The choice of pump series and materials

The choice of pump series and materials

When the type of pump is determined, the material of the pump can be selected according to the characteristics of the medium.

If you decide to choose a centrifugal pump.Further consideration could be given to the following items:

① According to the characteristics of the medium to decide which characteristics of the pump, such as clean pumps, corrosion resistant pumps, or chemical process pumps and impurity pumps and so on.

When the medium is highly toxic, valuable or radioactive substances that are not allowed to leak, it should be considered to use non-leakage pumps (such as shield pumps, magnetic pumps) or double-end mechanical seals with leakage liquid collection and leakage alarm devices.

If the medium is volatile liquid such as liquefied hydrocarbons, low cavitation margin pumps should be selected, such as barrel pumps.

② Choose horizontal pump, vertical pump (under liquid pump, pipeline pump) according to the site installation conditions.

③ According to the flow size, choose single suction pump, double suction pump, or small flow centrifugal pump.

④ Select single-stage pump, multistage pump, or high-speed centrifugal pump according to the height of the head.
