Big Flow Rate Self Priming Waste Water Pump

Big Flow Rate Self Priming Waste Water Pump is designed for economical & trouble-free operation in handling solid-laden liquids and slurries.

Big Flow Rate Self Priming Waste Water Pump

Big flow rate self priming waste water pump, also named solid-liquid pump or trash pump, is featured by distinctive hydraulic design, with impeller restricted within a single impeller bowl connected by pumping chamber. When impeller rotates, the liquid inside pump produces violent axial vortex, thus making inlet vacuumized and outlet provided with head. In this way foreign substances can be discharged out of pumping chamber. That is to say ,its flow channel is fully cleared, making it’s discharging capability unparalleled compared with other self-priming pumps.

Big flow rate self priming waste water pump produced by our pump can be used like common clean water pump without bottom valve, also can suck and transfer big solid ,long fiber, sediment, waste ore impurities, faeces and all of engineer sewage.

Widely applicable for the lines of urban discharge projects, light industry, paper making, textile, foodstuff, chemicals, electric power, petroleum, mines,   agriculture and so on. It is an optional choice of trash pump at home to handle solid particles, fiber, paste, mixed or suspended mediums etc.
