What are the considerations when choosing a pump?

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.
