The Selection Of Acid And Alkali Resistant Sewage Pump

The selection of acid and alkali resistant sewage pump should start from two aspects.

Tools / raw materials

1. Acid and alkali resistant sewage pump material corresponding to the acid and alkali value of sewage.

2. Power of acid and alkali resistant sewage pump corresponding to flow head

Method

A. First, determine the acid-base characteristics of sewage. Generally, the pH value of sewage is between 5 and 9. It is OK to select FRPP (polypropylene plus glass fiber) material for acid and alkali resistant pump. If the pH value is less than 5, it is strong acid. PVDF should be selected for alkali resistant centrifugal pump. If the pH value is greater than 9, it is strong alkali, and pure PP or CPVC material should be selected.

B. Then determine the sewage flow and the distance and height of the alkali resistant water pump to be delivered, so as to determine the power of the sewage pump. The flow and head of the acid and alkali resistant sewage pump are inversely proportional,

C. It is necessary to determine whether there are particles with high hardness in the sewage. To the corresponding selection of acid and alkali resistant sewage pump shaft seal material.

D. The installation position of acid and alkali resistant sewage pump shall be determined so as to determine whether the acid and alkali resistant sewage pump has self-priming function.

E. To determine the temperature, in order to determine the acid and alkali resistant sewage pump material and whether to use high temperature bearings.

Attention

The acid and alkali resistant sewage pump shall not be exposed to the sun for a long time in use. There should be places for shading and shelter from rain.The inlet of the acid and alkali resistant sewage pump shall be equipped with a filter device, and the outlet shall be equipped with a non-return valve device to avoid further damage of the sewage back-flow.
