Wastewater Pumps Information Wastewater pumps are used in the collection of sewage, effluent, drainage and seepage water in locations such as homes, farms, light commercial buildings and industrial areas. Many wastewater pumps use centrifugal force or positive displacement to move fluids. Centrifugal pumps apply centrifugal force to generate velocity, use rotating impellers to increase velocity, and push fluids through an outlet valve. Positive displacement pumps use rollers, gears, or...

Q:
What new technologies are influencing wastewater pump design?
11 answers
Answers:
VFD's have been the biggest overall change in the wastewater pump design; it has forced manufacturers to upgrade their motors to effectively operate in a system with VFD's. Secondly the use of the vortex impeller design, which has been available for years, is becoming more acceptable due to it's forgiving characteristics which allows for longer service life.

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using wastewater pumps?
7 answers
Answers:
1- Lower speeds means longer life time 2- Control panel with high protections 3- Bigger pumps does not means it will cover your requirement --- May be the smaller one is most suitable for you ---- which means you should know the suitable required head and flow rate
~Moustafa H, Marketing/Sales, Buraidah, SAUDI ARABIA
Purchase a pump that will give you longevity and don't be fooled by high efficiencies or cutting mechanisms.
~Chad S, Marketing/Sales, Powhatan, VA
Take into account the amount of solids that the system is likely to handle.
