This sewage cutting pump is designed with a unique cutting method, and the impeller adopts a semi open rotating design. The design features high efficiency in cutting pollutants, fast discharge, and high energy efficiency. Cutting and crushing debris such as plastic bags and cloth strips in general sewage can prevent blockages during discharge. The impeller is made of 3Cr13 material and has undergone heat treatment to increase wear resistance, making it less prone to damage and rust, thus extending the lifespan and increasing efficiency of the water pump.
