How to choose suitable feeding pump for wastewater treatment?

The function of feeding pump is to continuously send slurry into filter chambers. The filtration rate depends on feed pressure, while feed pressure is related to strength of filter press and head of feeding pump. Therefore, when you choose the pump, you should consider both pump performance and matching degree. The common feeding pump includes centrifugal pump, screw pump, plunger pump and so on. At present, the most common centrifugal pump used in industrial production includes common pump, stainless steel pump, and slurry pump and so on.

The chosen principle of feeding pump

1. The type and performance of feeding pump should meet requirements of rate of flow, head, pressure, temperature, cavitation flow, suction head pump and other technological parameters.
2. It must can meet requirements of media characteristics: reliable shaft sealing or zero leakage pump are necessary for sending inflammable, explosive, poisonous or valuable medium, such as membrane pump, canned motor pump and magnetic force driving pump. The pump that sends corrosive medium should adopts anti-corrosion convection components.
3. In terms of mechanical properties, it should has higher reliability, lower noise and smaller vibration.
4. You should consider the total cost, including equipment cost, running cost, maintenance cost and management cost.
5. The centrifugal pump is featured with high rotate speed, small volume, light weight, high efficiency, large flow rate, simple structure, stable performance, easy operation and maintenance and so on. Therefore, this kind of pump may be a good choice in most conditions.
