Seaflo Water Pump 41 Series

The SEAFLO 12V Series 41 Diaphragm Water Pressure Pump, is a general-duty positive displacement pump. Typical applications include: Marine, RV, Agricultural Spraying, General Industrial, Filtration, Beverage Processing, Solar Water System

Thanks to the quad chamber diaphragm and internal bypass, the 41-Series pump provides high volume water flow with reduced pump cycling.

It excels in providing high-water flow - up to 4.5 gallons per minute - with moderate pressure and is suitable for all activities needing these requirements. These models are designed to run on water systems with up to 5 outlets and no accumulator tank. It is also suited for use with a holding tank water system, as may be found in a boat, RV or remote cabin.

The 41-Series pumps are self-priming, and can run dry without damage.

It also features a built in pressure switch, allowing the unit to start and stop when it detects a faucet being opened. These pumps are supplied with 12mm and 19mm fittings. They're easy to install service and winterize with quick snap-in port fittings.
