Seaflo Diaphragm Pumps


Seaflo Series 31, 33, 35 and 52 are on demand positive displacement pumps.

Each series offers a different combination in output, duty type, connector type and pressure.

They provide reliable performance in moderate water flow, high-pressure applications.

The 3 chamber diaphragm pump provides excellent water pressure and is capable of self-priming up to 1.85 metres. Seaflo pumps can run dry without damaging components.

These automatic demand water system pumps have a built-in pressure switch, automatically starting/stopping when the fixture is opened/closed.

They are simple to install and service.
