Do a search on Google for the Pondmaster Mag-Drive pumps. They use a lot
less electricity and only have 1 moving part.

Hello: I've estimated that I need a pump that pushes 3500 gallons/hr at 7'
head. Is there a good website to compare different pumps and their
capabilities? There seem to be so many varieties of pumps I've had a hard
time finding what models are available that can do this. Also, could someone
explain how i go about deciding if i need a 1/8HP vs 1/4HP etc?



Of course if anyone wants to recommend a specific pump model that would be
helpful too.



Thanks for any help you can provide.
