Non-clog sewage low flow high head pump
Non-clog sewage low flow high head pump
(OP)
I need some help finding a pump (or other method of conveyance) that can pump sewage at approximately 170 gpm and 314' TDH, efficiently. We have thought of two pumps in series and two lift stations, but that seems that it would be an operator's nightmare. The operating point is peak wet weather flow at 4 feet per second over 9,500' for a dynamic head of 154' and an elevation head of 160'.

Seems stanier's suggestion could be a good way to go.

This type of installation is far less costly than a reciporcating pump. These types of pumps would require a macerator as the clearances through the valves is not large enough for your process. They are also high maintenance items in such service. Pumping sewage is an intermittent duty normally. Settling of solids in such valve chambers causes problems.
