The SEAFLO 12v Series 41 17L/M Diaphragm Water Pressure Pump is a general-duty on-demand positive displacement pump. 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, 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. The unit is 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. Our SEAFLO pumps come with a 3 year warranty.
