SPX Johnson - 10-13399-04 - Aqua Jet Wash Down Pump System 3.5 - 24 Volt

The Johnson Pump WPS 3.5 can be used for domestic pressure of a wash down pump using sea water. It is the only Aqua Jet with a built in dampening device where a spring loaded valve allows high pressure water to bleed back into the pump head when a tap is slammed shut or the water flow is less than 4 litres per minute. This dampening device reduces duty cycling of this motor and dissipates harmful water hammer. This pump can therefore be used for domestic pressure or wash down in marine, RV and rural applications.


Complete with Spray Pistol, PUMProtector Inlet Strainer and Hose Connections for 1/2" hose
