What Is The Difference Between Sewage Lift Pump And Clean Water Pump

What is the difference between sewage lift pump and clean water pump? About the relevant knowledge of sewage pump and clean water pump, many friends do not know much, today we come to understand it!

Sewage lifting pump belongs to the scope of centrifugal pump, structure and principle and general centrifugal pump is the same. Sewage pump also has its own structural characteristics, sewage pump head is not high, due to more debris in the sewage, the clearance of the impeller is larger than the clean pump. Sewage pump prone to failure, and the general centrifugal pump is similar, because of pumping sewage, so the impeller wear faster.

Sewage lift pump impeller, than the water pump is simple, no ring, so that it will not be when the sewage grass, there is a serrated blade under the impeller, the water pump can be adjusted up and down, can put the thread, cloth ground and extracted.

Ordinary clean water pump is designed to obtain the highest efficiency, that is to say, the hydraulic structure parameters of the clean water pump is the best combination of obtaining the highest efficiency. For sewage pumps, this kind of pump with special requirements, its efficiency can not exceed the efficiency of the clean water pump at the same time.

The main reason that the efficiency of sewage lift pump is lower than that of clean pump is that their flow channel is widened. The value of efficiency decrease is mainly related to the degree of widening. The flow channel of the sewage pump is widened to prevent obstruction.

Clean water pump belongs to the scope of centrifugal pump, clean water pump structure and principle and general centrifugal pump is the same
