Pump design for maximum flow

Pump design for maximum flow

Pump design for maximum flow

(OP)
Guys,

I have 2 duty pumps for a storm water pumping station. Is it absolutely necessary that we design these 2 pumps for 100% of the flow capacity? What are the factors that would determine this decision.

RE: Pump design for maximum flow

What would depend on the peak load and minimum load and what happens in between. In many instances it is preferable to design for 3 × 50% units which covers a far greater range of flows within the pumps hydraulic capabilities.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

RE: Pump design for maximum flow

Perhaps you can add some more details to your question as it is not clear what you are referring to.

RE: Pump design for maximum flow

In general, you would design a pumping station to pump the design flow with one pump out of service.
So you would need 3x50% as Artisi said.
