FAQ

Motor is an indispensable part of the industrial automation and one of the most common electrical equipment in life. It is widely used in various electrical appliances, ranging from washing machines and fans in daily life; For industrial applications, pumping, machinery industry and fluid transfer, etc. Motors are also indispensable when pumps are used. Therefore, it is very important to understand and choose a suitable motor. The following describes the differences between normal motors, inverter duty motors and explosion-proof motors.

 

Normal Motors

There are many types of motors, according to the type of input power, they can be divided into DC motors, AC motors, etc. DC motors can be further subdivided into brushed DC motor, brushless DC motor(BLDC motor); AC motor includes induction motor and synchronous motor. In brief, DC motor controls the rotational speed through voltage, which is easy to control, but not suitable for high temperature and flammable operating environments. The AC motor controls the rotational speed through the frequency of the alternating current, so compared with the DC motor, it is not easy to control the speed, while it can be used in a high temperature and flammable operating environments.

 

Inverter Duty Motors

A variable frequency drive (VFD) (a.k.a Inverter) is used to change the frequency of the alternating current, by changing and controlling the speed and torque of the AC motor. Therefore, "variable frequency" refers to the way of driving the AC motor. It can be started and adjusted frequently without maintaining full-speed operation and maximum power. When the motor speed is reduced, the output horsepower will also decrease, thereby achieving high efficiency and energy saving. The system control is also more stable than the normal traditional motor.

 

Explosion-Proof Motors

Mainly used in operating environments where flammable substances exist, such as coal mining, natural gas industry, petrochemical and chemical industries, etc. With the hard explosion-proof shell, it can sustain the explosion pressure inside the motor, and also can isolate the heat from the inflammable materials, so as to avoid the danger of fire or explosion.

According to the explosion-proof form, it can be roughly divided into flameproof motor (symbol d), intrinsic safety motor (symbol i), increased safety motor (symbol e), positive pressure explosion-proof motor (symbol p), non-sparking motor (symbol n), and dust ignition proof motor, etc., depending on the protection level, each has its features and functions.

 

With a brief understanding of the differences between these motors, I believe it becomes easier to choose the right motor for your needs.

The pump is a general rotating machine, and its operating power comes from the motor. The types of pumps include sealless magnetic drive pumps, mechanical seal pumps or other forms of centrifugal pumps, all of which must be connected to a motor to deliver the fluid.

 

Motors can be divided into general motors, inverter duty motors and explosion-proof motors. The specifications of the motors are also different according to the application and environment. The following describes about how to select a suitable motor according to the requirements when using a pump.

 

For different purposes, it can be based on motor specifications, such as the number of poles (Pole), RPM, the frequency (Hz), voltage (V), the install location, IP Rating, and the energy efficiency index to decide which model to choose.

 

Pole, RPM, Frequency(Hz)

Pole represents the number of magnet poles in the stator magnetic field of the motor. According to the different connection forms of the stator coil windings, different numbers of poles in the stator magnetic field can be generated. The number of poles affects the rotational speed of the motor.

 

RPM stands for revolutions per minute. For example, the rotational speed of the motor is 3,600RPM, which means that the motor can rotate 3,600 revolutions per minute.

 

Frequency (Hz) refers to the frequency of the alternating current (AC) is the number of cycles per second in an AC sine wave. Frequency is the rate at which current changes direction per second, in the international measure Hz as the unit, we use 50Hz or 60Hz in the general worldwide.

 

RPM formula: RPM= Hz x 60(sec/min) x 2 ÷ number of poles

Therefore, under normal circumstances, when the frequency is 60Hz, 2P runs 3600 rpm, 4P runs 1800 rpm, 6P runs 1200 rpm, and so on. It can be seen from the formula that the number of poles, frequency and rotational speed are closely related to each other.

 

Voltage (V)

The voltage is proportional to RPM, that is, the higher the input voltage, the faster the motor rotates; the lower the input voltage, the slower the motor rotates.

 

IP Rating& Install Location

IP rating is usually marked with IPXX, such as IP54, IP55, IP56, etc. The first number after it represents the protection against contact and intrusion of solid foreign objects, and the second number represents the protection against ingress of liquid.

The motor can be installed indoors or outdoors according to the IP rating, depending on whether it can resist damage caused by wind, sun, rain, as well as customer operation requirements, noise problems and other conditions.

 

Energy Efficiency Index

International Efficiency is defined by the International Electrotechnical Commission (IEC), and the energy efficiency levels are divided into IE1, IE2, IE3, and IE4. The larger the number, the better the efficiency and the more power saving.

 

The above are the relevant specifications that must be referred to when selecting a motor. Next, the differences and applications of general motors, inverter duty motors  and explosion-proof motors will be introduced.

We need to understand the operating condition in the consideration for pump selecting in previously introduced. After understanding the basic concepts, it is necessary to explain how to read the "pump performance curve (H-Q curve)". The performance of each pump model is different, and the most suitable pump must be selected according to the pump performance specifications and the operating conditions provided by the customer.

 


In the performance curve diagram, the horizontal axis is the CAPACITY (Q), the left side of the vertical axis is the HEAD (H), and the right side of the vertical axis is the EFFICIENCY (%) and shaft power.

The first gray straight dotted line is the shaft power curve under the maximum diameter of the impeller, the second gray straight dotted line is the shaft power curve under the minimum diameter of the impeller, and the red straight line(POWER) is the pump shaft power performance curve that meets the operating requirements provided by the customer.

 

The first gray dotted curve in the figure is the performance curve under the maximum diameter of the impeller, the second gray dotted curve is the performance curve under the minimum diameter of the impeller, and the red curve(TDH) is the performance curve that meets the customer's operating requirements of the pump, we call duty point, which is what we get by adjusting the size of the impeller, showing the relationship between capacity and head. The green curve(EFF) is the operating efficiency of the pump.

 

 

According to the flow demand of the horizontal axis, you can find the duty point by comparing the red curve upwards. By comparing the duty point to the left and right vertical axis, we can know the head and efficiency; then comparing the red line upwards, from the intersection (shaft power) to the right vertical axis, we can know how much the power is under this operating condition.

 

The efficiency of the pump depends on the duty point, and the change of the duty point will also have a great impact on the field process, so the correct selection of the pump is very important.

If basic preventive maintenance measures are taken, the sealless magnetic drive pump does not often fail. However, in order to have better pump quality and operating efficiency, there are several basic concepts which we need to know. The following describes the main problems that may be encountered when using a pump.

1. Pump Dry Running

When the flow rate is insufficient or the liquid is not filled with the pump, dry running will occur. If the pump run dry, its internal components (such as impellers, bearings, etc.) will be rubbed, resulting in a lot of frictional mechanical heating and pressure, which will cause the magnet to demagnetize and then damage the pump.

2. Motor Overload

Motor overload occurs when a motor is under excessive load. The primary symptoms that accompany a motor overload are excessive current draw. The main reasons for the excess current are the increased load at the outlet of the pipeline, high lift, poor heat dissipation, blockage of the pipeline, wrong selection of the motor or pump, etc. At this time, the operating power will increase. During a long-time operation insufficient torque and overheating, the motor may cause burn out. 

3.Cavitation 
During the operation of the pump, if the pressure of the pumped liquid drops to the vaporization pressure of the liquid at the current temperature due to the large resistance of the inlet pipeline and the large gas phase of the conveying medium in the local area of ​​ the overcurrent part (commonly found in the impeller), the liquid begins to vaporize to form bubbles. After the bubbles enter the impeller with the liquid, the surrounding high pressure causes the bubbles to shrink sharply and even burst.

At the same time when the bubbles are condensed and broken, the liquid particles fill the cavities at a high speed, which produces a strong water hammer at this moment, and hits the metal surface with a very high impact frequency.
Cavitation is the most harmful to the pump.
When cavitation occurs, the pump vibrates violently and makes noise, which will cause damage to the pump bearing, rotor or impeller.

4. Decoupling
As the temperature increases, the strength of the magnetic is weakened or the viscosity of the fluid is too high, the transmittable torque is less than the required torque, and if it continues to operate without cooling or sufficient torque, there will be demagnetization problems, which will cause the magnet to demagnetize and then damage the pump, resulting in failure.

In order to avoid these problems, the dry run protector is used to monitor the current or power of the pump motor when it is running. When the current is too high or too low, an immediate warning or automatic shutdown will be issued, which greatly reduces the probability of pump failure and maintenance costs.

In the selection process of the pumps, the following factors should be considered to select the appropriate pump.

1. First of all, it is necessary to confirm the source of the fluid:

Such as the underground storage tank or the above-ground storage tank, how far the tank is located, the pipeline configuration and other conditions. It is recommended to install the pump as close as possible to the source of the fluid, and the suction pipe should be as short as possible, and also reduce bending or other fittings to reduce the pipe friction loss, which is the resistance of the fluid passing through the pipe.

2. Capacity(Q):

This is an important indicator, which refers to the amount of liquid passing through the pump per unit time, in m³/h, L/min, L/sec. The amount of flow will affect the size of the pump and the thickness of the piping. If the pipe diameter is too small, it will cause extra friction loss and noise problems.

3. T
otal head(H):

It refers to how high the pump can move the liquid, that is, the vertical height from the source surface of the fluid to the final outlet.

H = Total Head (in meters)= Discharge Head + Suction Head

The height of the head depends on the density of the conveyed liquid, the diameter of the impeller and what type of stage of the impeller.

4. Properties of fluid:

Chemical corrosive, temperature, viscosity, concentration(%), specific gravity and impurities are also the key point of choosing a pump.

Chemical corrosive: According to the difference of the pH value of the fluid and its corrosive, the applicable pump material is also different.

Temperature: When treating water, the temperature has a great influence on the suction capability; other liquids will vaporize at a certain temperature; oil and fats will significantly change their viscosity due to the temperature; The expansion of the material must be taken into account when the heat medium is in a high temperature state; and the chemical fluid will also change its corrosive with the difference of the temperature.

Viscosity, Concentration, Specific Gravity: When the viscosity and concentration of the liquid change, it will affect the corrosive to metals and other materials, and the specific gravity will change accordingly. Therefore, the pump performance will also change.

Impurities: The sand contained in the muddy water and the crystals in the chemical liquid. According to their hardness and content to select the structure of pump, and wear-resistant materials must be used at the same time.

A sealless magnetic drive pump is a conventional centrifugal pumps and sealless magnetic drive pump working principle, the inner magnet and outer magnet are attracted to each other, the outer magnet is connected with motor shaft, and inner magnet is assembly with impeller, as the motor shaft rotates the magnetic attraction forces inner magnet to rotate, thus rotating the impeller and causing chemical liquid to be pumped.
A sealless magnetic drive pump is a conventional centrifugal pump of which design concept is to not use of any mechanical shaft seal. Compared with traditional mechanical shaft seal type of pump, sealless design does not have any leak problem and it is commonly used to transfer hazardous, flammable, explosive, strong acid, strong alkali, or toxic chemical liquid.

Sealless Magnetic Drive Pumps
The sealless design structure is to use rear casing to completely seal the inner magnet, impeller and other wetted parts in the fluid chamber. Outer magnet transmits by motor shaft and inner magnet is connected to the impeller which rotates by magnetic traction and transfer fluid through the pump. Due to the isolation of the fluid by a rear casing, it creates a sealless containment. The sealless design brings leak feature.



Mechanical Seal Pump
A mechanical seal pump uses a driven motor to directly rotate the impeller and transfer fluid. The difference of a mechanical seal pump is that a motor shaft goes through rear casing and requires a mechanical seal to prevent any leak. Mechanical seals are consumables and maintenance or replacement is required for long-term use. Fluids often leak through the seal position and cause danger in a mechanical seal pump.

  Sealless Magnetic Drive Pump Mechanical Seal Pump
Leak Problem Leak-free feature for handling hazardous or volatile chemicals. Mechanical seal design with leak concerns, not recommend for handling hazardous or volatile chemicals.
Installation and Maintenance A sealless magnetic drive pump provides quick and easy installation without special tools. Special tools are required for maintenance or replacement of mechanical seal, and aligning is required for installation to keep the balance during operation.
Extra Monitoring The use of operating fluid for heat dissipation and lubrication, and no additional equipment for cooling or monitoring. Extra equipment needed to monitor the pressure and temperature on the mechanical seal, and refluxing tube to lubricate the seal.
Cost Effectiveness No additional monitoring or maintenance is required to improve the pump life cycle which reduces labor and time during installation and maintenance. Mechanical seals are consumable parts and require regular replacement, which is costly. The maintenance, complicated installation and replacement often increase downtime.
Safety Leak-free for better environment. Mechanical seals have leak or VOCs problem during operation which will cause safety concerns for the environment and users.

When the pump is running, mechanical heat will be generated due to the rotating parts. A sealless pump uses its own operating fluid to dissipate heat and lubricate the rotating parts. When no fluid enters the pump chamber, the internal temperature will rise and the pump dry runs for a long time, it might cause magnet demagnetization to damage parts.

  1. Use screwdriver to rotate the motor’s fan to ensure it is not too tight or stuck.
  2. Check the motor’s power rating including frequency, voltage and wiring.
  3. Clean piping system and supply tank.
  4. Recheck to make sure all the screw parts (flange, pump casing, baseplate, etc.) are securely fastened.
  5. Fill the pump with liquid to remove any air within the pump and suction piping.
  6. Check and make sure all the inlet calve of system is open.
  7. Make sure before start up the pump, and exhaust the inlet piping system and pump internal air.

Visual Inspection
1. Check for corrosive or damage to the front casing, bracket, and baseplate.
2. Check for leak of pump and piping system.
3. Check the pump and motor surface for physical damage such as
corrosion, paint peeled off.

Operating Inspection
1. Check for the unusual sound, vibrations when pump is running.
2. Check for any abnormal overheating on the surface of motor, current and motor loading, noise, foreign objects blocking the vent of fan, etc.
3. Check for liquid level in tank and inlet & outlet pressure.

How temperature affects pump selection
Do you know that temperature is a key factor in pump selection? It includes the temperature of the process medium and the environment of installation. Understanding these will ensure that you choose the right pump structure and material, and the most important thing is to select the right pump.



Temperature
Temperature refers to the heat present in a gas, liquid or solid. In the selection of the pump, we need to consider both the atmospheric temperature and the temperature of the pumping medium.



Temperature and pressure
Temperature not only affects the stability and efficiency of operation, but also affects the pressure of the pump delivery system. When the temperature of the gas approaches zero, it becomes a liquid, and as the temperature continues to increase, the pressure of the gas also increases. Different media generate pressure in different ways, before we design a system for pumping and conveying media, must be considered the connection between temperature change and pressure, If this is not considered, and the pump selector is not aware of how gasses will respond to temperatures within the system, faults can occur costing the business time, money, and production.



Zero degree environment
When the pump is installed or moved outdoors and the temperature drops overnight, the fluid medium inside the pump may freeze or solidify. When the pump is restarted, parts may be damaged. When selecting pump, we need considered the install environment, heating jackets may be required to maintain a consistent temperature within the pump or insulation. Consistent to avoid freezing or solidification of the fluid medium.



How temperature affects your pump
The material of pump selection, corrosion can occur depending on the temperature, high temperature liquid has more corrosive action against the material than those at lower temperature liquid. Therefore, is important to check the chemical compatibility of material at the temperature be for selecting a pump.



Pump Component Selection
As the temperature of the liquid medium increases, heat will be transferred to the entire pump system, including the internal shaft, bearings or bearings on the motor. Long-term operation may lead to shortened service life; therefore, the selection of parts also needs to consider temperature resistance level.



Changes in fluid viscosity
Temperature will affect the viscosity change of the liquid medium during the pumping process, for example, honey when heated becomes runny, therefore, it is necessary to understand how temperature change's liquid medium viscosity during pumping, and ensure that the correct pump is selected.



Part expansion and contraction
Under high temperature or low temperature, the parts will expand or contract at different speeds. When selecting the pump, it is also necessary to consider the use of high temperature or low temperature resistant parts to ensure the stability of the pump during operation.



Keep the heat ot maintaining low temperature
Under certain operating application conditions, the medium needs to maintain a certain temperature to keep the medium flowing. The system design can consider using a jacket type pump to achieve this, or use proper insulation to maintain a low temperature.



NPSH net positive suction head (NPSH)
When designing the pumping system, the temperature and vapor pressure of the fluid need to be considered to ensure that the pump has the correct NPSHa.

Hydrogenic Energy

The hydrogen revolution is happening. No matter in electricity generation, transportation, oil refining or chemical industry, hydrogen is gradually replacing fossil fuels, becoming the promoter of energy transition, and playing a key role in realizing low-carbon energy in industry.


What is Hydrogenic Energy?


Hydrogen energy resource is a new renewable energy resource. Since the molecular structure of hydrogen does not contain carbon, the use and production of hydrogen energy can greatly reduce carbon emissions. In addition, excess electricity from renewable energy such as wind energy and solar energy can also be used to convert water into hydrogen through electrolysis, it can be stored for a long time and in large quantities, and converted into electrical energy when needed. It can be seen that hydrogen is a clean, environmentally friendly, efficient and multifunctional energy carrier.

Hydrogenic Energy


What is Hydrogen? The Colors of Hydrogen?


Hydrogen does not exist in nature, it needs to be produced, and can be obtained through electrolysis of water by renewable energy, or steam methane reforming. Even though hydrogen will only produce water after combustion or chemical reaction, and will not emit any carbon or pollutants, the amount of carbon emissions produced during the process is still different depending on the source of materials and production methods, and the color is often used to differentiate hydrogen type.


  1. Grey Hydrogen
    Using fossil fuels such as natural gas (mainly methane) for steam methane reforming, water vapor reacts with hydrocarbons to convert hydrogen, which is the most commonly used and lowest-cost manufacturing method today. The disadvantage is that the by-products emitted contain a lot of carbon dioxide.
  2. Green Hydrogen
    Using renewable energy (such as wind energy, solar energy) or nuclear energy to do water electrolysis to produce hydrogen, which has the advantage of almost zero carbon emissions in the process. The disadvantage is that the cost of electrolyzer is high, and the conversion efficiency of water electrolysis is only about 70-80%.
  3. Blue Hydrogen
    Hydrogen is produced by steam methane reforming of fossil fuels such as natural gas (methane), but with carbon capture and storage (CCS) in the process.
  4. Brown Hydrogen
    Brown hydrogen is produced via coal gasification. The disadvantage is that the CO2 and carbon monoxide released as by-products during the process are not recaptured, causing high degree of pollution to the environment.

In order to achieve the goal of 2050 Net Zero Emissions, it is necessary to gradually increase the proportion of low-carbon hydrogen such as green hydrogen and blue hydrogen. Countries are committed to researching mature green hydrogen manufacturing technologies to alleviate global warming and energy crisis.


Electrolyte Circulation


In the electrolysis technology for producing green hydrogen, a key step is to pass electricity into the electrolyzer containing the electrolyte (typically potassium hydroxide) so that the electrolyte and water are mixed and circulated between the cathode and the anode, and then occurring chemical reaction, split into hydrogen and oxygen. In this electrolyte circulation system, PTCXPUMP sealless magnetic drive pump with the characteristics of leakage-free and corrosion resistance can ensure safety in use, and become the best solution for transporting potassium hydroxide or other electrolytes.

Electrolyte Circulation


Hydrogen Economy


The hydrogen economy was proposed by General Motors (GM) in 1970, which refers to a new economic structure that replaces petroleum with hydrogen and widely uses hydrogen as the main energy carrier. With the trend of hydrogen economy, innovative and advanced hydrogen application methods will be gradually developed, and wider application fields and markets will also appear at the same time.

Hydrogen Economy

However, hydrogen gas is an explosive gas and is easy to leak. In addition, hydrogen molecules are small and easy to penetrate into metal materials, resulting in reduced ductility and "hydrogen embrittlement". Therefore, there are special demands on pumps for handling and transporting hydrogen.


Conveying Solutions Without Leakage Concerns


In order to save storage space, it is necessary to compress and liquefy hydrogen before transporting it. A compressor is used to compress gaseous hydrogen, and then the hydrogen is cooled to turn it into liquid hydrogen. The storage of liquid hydrogen requires low temperature and high pressure resistance, so complete gastightness is one of the key to hydrogen process system. In order to avoid hydrogen leakage or external gas mixed with hydrogen, resulting in impurities in the gas, a sealless magnetic drive pump must be used, which helps to improve efficiency and cost management.

If you are also ready to respond to the global trend of net zero emissions, please contact us to choose the most suitable pump for hydrogen energy applications.


In order to meet the needs of different conditions of the human body, there are countless types of medicines now. Since the outbreak of Covid-19 in recent years, the pharmaceutical industry has developed rapidly. However, since medicines are used on the human body, safety and non-pollution are the primary conditions in the manufacturing process.
In order to ensure that the medicines can meet the legal and hygienic standards during and after the production, the types and materials of the pumps used in the production process are very important.


Application of Cosmetics Industry and Pharmaceutical Industry


In a society where both women and men pursue beauty, cosmetics have apparently become one of the necessities for grooming themselves. In the production of cosmetics, in order to reduce the number of organics and microorganisms and minimize the concentration of bacteria, ‘deionized water’ must be used in the cleaning process of the cosmetics process, and the sealless magnetic drive pump has leakage-free characteristics and is suitable for transportation DI water to ensure cosmetic hygiene and safety.



In pharmaceutical production, the materials of the pump must be carefully selected. If the material is cut corner or the material is not selected correctly, the product may not meet the standard, and the huge loss caused by this deficiency may also be borne.


In order to avoid serious accident, sealless magnetic drive pumps can be used in equipment such as chemical dispensers, which can effectively keep medicines sterile and pure, and also take into account safety and efficiency in the process.


The wastewater treatment in pharmaceutical factories cannot be ignored either. Since pharmaceutical wastewater has a high salt content and may contain toxic substances, it is necessary to pay attention to corrosion resistance in the selection of equipment for treating pharmaceutical wastewater.


What is the Best Material for Handling Medical Devices?



Because the process of pumping medical chemicals must be as error-free as possible, reliable medical equipment materials are key, and polypropylene (PP) is an ideal material. Polypropylene is a plastic material resistant to acid, alkali and high temperature, and has good chemical stability, so it can also provide safe use in medical devices. We recommend the PTCXPUMP sealless magnetic drive pump – polypropylene for the impeller, front casing, rear casing and baseplate, or other durable materials such as plastics for O-rings, shafts and thrust rings, fine ceramics or SiC.
