Core Concept

Environmental protection and user safety are always been the main focus of PTCXPUMP product development, The chemical pump structure is designed in the form of sealless magnetic drive, sealless design is to solve the leakage caused by mechanical seals and VOCs problem.

PTCXPUMP is a professional sealless magnetic drive pump manufacturer in Taiwan, with more than 40 years of experience in chemical fluid transfer solutions, we completed research and development and started mass production in 2014. The product materials provide engineering plastics GFRPP and CFRETFE, and stainless steel material SUS316L is available for selection, pump is being used in various range of chemical fluid, such as hydrochloric acid, sulfuric acid, hydrofluoric acid, toluene, ethanol and other high corrosion or flammable chemical fluids.

PTCXPUMP with sealless leakage free feature, products come with high-standard production processes and material selection, we follow standardization of internal work processes and enhance the reliability of product competitiveness and quality. Products are widely used in petrochemical, fine chemical, energy, semiconductor, optoelectronic, electronic, environmental protection and other industries.

Pump Maintenance Guide

When we use the pump, in order to maintain its performance and avoid operational problems, there are some maintenance and methods of routine job that need to be understood. The following will introduce how to maintain and inspect the pump to extend the service life of the pump, in order to reduce maintenance costs.

According to the difference in initiative, the types of maintenance are mainly divided into corrective maintenance and preventive maintenance.

What is Corrective Maintenance?

Corrective maintenance: When the pump leaks, the efficiency decreases, stops or the motor failure, resulting in production loss, it is necessary to quickly purchase or install spare parts in an emergency to restore the equipment system to an operational condition.

What is Preventive Maintenance?

Preventive maintenance: Routine or regular (hourly, daily, weekly, monthly, yearly) scheduled inspections aimed at maintaining the equipment in its current state and preventing malfunction, by dismantling devices, replacing seals such as gaskets or mechanical seals, and checking the pump's external and internal parts for wear.

In addition to the necessary to ensure that the pump can operate normally after started through some inspection steps, carrying out the routine preventive maintenance through the following checklists is also a point of pump protection.

Routine inspection:

1. Check the pump body, connection plate and base plate are corroded or damaged.
2. Check whether there is leakage between the pump and the piping.
3. Whether the surface of the motor is damaged or corroded.
4. Whether the pump is operating normally, and check there is any abnormal noise or vibration.
5. Confirm the flow and pressure at the pump inlet.
6. Confirm the flow and pressure at the pump outlet.
7. Confirm the liquid height in the tank.
8. Whether the motor current value is within the rated range.

If there are spare parts, it is also necessary to test run frequently and check whether they can work normally.

Regular inspection:

(depending on the usage conditions and hours, about once every 3 to 6 months)

1. Front casing, rear casing
Check for cracks, abnormal wear, crystallization, or foreign matter attached.

2. Gasket
Check for deformation, corrosion, or swelling.

3. Impeller and inner magnet
Check for scratches or cracks, crack or crystallization on bearings, bearing wear or tear, deformation of the impeller, etc.

4. Shaft
Check for scratches or cracks.

5. Rear casing
Check for corrosion, cracks, holes and scratches.

In addition to the above-mentioned maintenance and detection methods, preventive maintenance also includes the use of monitoring technology to determine the current operating status of system equipment. In order to correct the pump problem before it occurs, the current or power of the pump motor can be monitored by using PTCXPUMP dry run protector. When the current is too high or too low, an immediate warning or automatic shutdown will be issued, which greatly reduces the pump failure probability and maintenance costs.

Considering preventive maintenance, PTCXPUMP sealless magnetic drive pump can reduce the cost of preventive and corrective maintenance because of its simple structure and high durability.
