The Seaflo 42-Series pump provides high volume water flow with reduced pump cycling, thanks to the quad chamber diaphragm and internal bypass. The "42"  can adapt to situations where huge flow is not needed and is more compact that the "Series 41".  It is a great fit for tight spaces and may be configured with different inlet types, each with their own unique fittings, to be sure that it fits any application you can find.

This pump provides up to 3.0 gallons per minute. The 42-Series pumps are self-priming, and can run dry without damage, performance reliable and low current. This automatic demand water system pump has a built-in pressure switch, which automatically starts and stops the pump when faucet is opened and closed.
