Powerful pressurised water pump with a long service life. Thanks to its silent operation and even water flow, this pump is the best solution for your pressurised water system on board. The WPS diaphragm pumps are equipped with a 5-chamber displacement system.
Even after switching off, the Johnson Aqua Jet provides upright pressure, and the built-in pressure regulator automatically switches off the pump after reaching the correct amount of pressure.
Key features
- Quiet operation
- Smooth flowing
- Self-priming
- Integrated pressure switch automatically turns the pump on and off when the tap is opened and closed.
- Safe to run dry
- Integrated bypass valve
- Low energy consumption
- Quickly disconnect the connections
Operating principle
When the pump is running, a pressure of up to 2.8 bar / 41 PSI is created. Once this pressure is reached, the pump switches off automatically. Positive-checking drain valves ensure that the pressure is maintained after the pump is switched off. If water is used (e.g. at the tap, shower), the pressure is reduced. In the event of a moderate pressure drop, the integrated pressure switch automatically reactivates the pump.
