The rubber material of rubber rotor pumps
Thread Content
Can a rubber rotor pump be used to handle domestic wastewater (toilet waste, kitchen waste)? Can a rotor made of nitrile rubber be used?
Why is a rotary pump used for pumping wastewater? Generally, positive displacement pumps are better suited for transporting media with higher viscosity; are submersible pumps more appropriate in such cases?
The wastewater is relatively clean after oil separation and sedimentation treatment. The rotor pump is also a positive displacement pump, so it’s relatively cheaper
A rotor pump is a positive displacement pump; rotor pumps are more expensive than submersible sewage pumps
What other types of rubber can be used?
Looking at water temperature, nitrile rubber can withstand up to 80 degrees, and hydrogenated nitrile rubber can tolerate boiling water.
