2 pumps inline ?

[hardy steve]

What's anybody think.2 pumps inline,but only one running.Second one sitting idle just as back up no power.Would the one pump struggle pumping water thru ?

i don't know-

i run two small pumps in case one fails, which did happen once

Are we talking water pumps or Hydralic pumps?

Don't run them in series. Parallel them instead.

Use check valves to keep water from back flowing through the other pump.

This

Parallel = same psi as one pump just moves more gpm
Series = same gpm but more psi. (have to consider hose max psi capability with this)

What is this for? sprinkler or fire protection?

Assuming we are talking circulation pumps for an OWB, I think TPA has it right.

Yep, as long as only one will be powered. Parrallel works best and eliminates a bunch of flow restriction.

Ball valves would be cheaper.

Ball valves would be cheaper.

Check valves properly installed need not be operated, they would do it automatically.
