The difference between sewage pump and clear water pump

What’s the difference between sewage pump and clear water pump? This question has been frequently asked, but not one convincing answer can be found even when you search throughout the internet. Today, Weihu sewage pump manufacturers will show you the difference between sewage pump and clear water pump.

Generally speaking, sewage pump is primarily used to deliver waste water, as well as fluids containing solid particles, such as fibers, paper scraps, hairs, etc., or fluids that are very dirty, sticky and slippery. It is applicable for sewage treatment in mines, paper making plants, chemical engineering industry, farms, etc. Clear water pump is mainly used to deliver clear water. It is suitable for municipal water supply and discharge systems, water heating and cooling circulation system, farmland irrigation, bath room, etc. As sewage pump and clear water pump delivers different fluids, they are different in flow channel design, lift distance, pump efficiency, impellers configuration, mechanical sealing, and raw material, as shown in detail in the following table. Sewage pump and clear water pump comparison table.

Pump type	Sewage pump	Clear water pump
Pumping fluids	Fluids containing fibers, hairs, etc.	Water and other fluids similar as water
PH Value	6~8	6.5~8
Flow channel	Designed primarily with large flow channel to prevent clogging	Often with small flow channel
lift	low	high
Efficiency	low	high
Impeller	Equipped with saw tooth blades to cut fibers and hairs	Complicated, improve efficiency
Material	Adopt sealing parts with better wear-resistant performance	Not strictly required
