Clear water pump and sewage pump in the structural difference

Sewage pumps are centrifugal pump range, structure and principle and the general centrifugal pump is the same. Sewage pumps also have their own structural features, sewage pump lift is not high, due to more debris in the sewage, impeller clearance greater than the water pump. Easy to produce sewage pump failure, and the general centrifugal pump is also similar, because pumping sewage, so impeller wear faster.

The sewage pump belongs to the centrifugal pump range, structure and principle is the same as the general centrifugal pump. The ordinary clean water pump is designed to obtain the highest efficiency, that is to say, the water pump structural parameters are the best combination to obtain the highest efficiency. Sewage pumps, such special requirements of the pump efficiency can not exceed the same period of the efficiency of the pump.

Sewage pumps, the efficiency is lower than the main reason for the water pump is their over-flow channel widened. The decrease in efficiency is mainly related to the degree of broadening. Sewage pump runner widening is to prevent clogging.

Sewage pump impeller than the water pump is simple, there is no retainer, so that will not live in the grass, the impeller below there is a sawtooth piece, you can adjust up and down, can thread, cloth pieces and extracted.
