Performance:
The suction capacity of the pump must be selected correctly, taking into account all influencing parameters.
Chemical resistance:
Some components of a pump are in permanent contact with the liquid to be pumped. It is therefore essential that these parts are resistant to the pumped liquid.
Liquids containing solids:
The maximum size of the solids in the pumping liquid can be found in the technical information.
Operating temperature:
The maximum operating temperature affects the pump components. This interacts with the liquid to be pumped.
Wear due to abrasion:
If the liquid to be pumped is very abrasive, the wear of the wearing parts (diaphragm, balls, ball seat) increases. This is reduced by selecting a larger pump than required. This can reduce the flow rate, which has a positive effect on the wear of the components.
Size of the system:
For proper operation of the pump, it is important to observe the following parameters of the system:
Suction pipe: Position the pump as close as possible to the suction point; if not possible, the maximum vertical distance is 6 metres.
Delivery pipe: The pipe must be selected in such a way that pressure loss in the system is avoided. The diameter of the pipe must be selected depending on the length of the pipe, the temperature and the viscosity.
