Engineered for flexibility

The Seaflo 5 Chamber DC Diaphragm Pump is Seaflo's heavy-duty water pump. It provides high volume water flow with reduced pump cycling, thanks to the five-chamber diaphragm. This model is designed to run on water systems with no accumulator tank necessary, and up to five fixtures! It's also suited for use with a holding tank water system, as may be found in a boat, RV or remote cabin.

The Seaflo 5 Chamber DC Diaphragm Pump is 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 the faucet is opened and closed. Plus, it’s easy to install, service and winterise.

How a Diaphragm Pump Works
In front of the motor is a valve assembly containing two to five valve pump chambers. Each valve chamber has a diaphragm behind it in the lower pump housing. As the motor shaft turns, an internal cam positioned behind the diaphragms causes the diaphragms to be pushed forward, then back in a continuous sequence creating suction. As this suction builds, fluid is pulled through the inlet, through the various valve chamber check valves to the outlet.
