The quiet and pulsation-free Aqua Jet five-chamber diaphragm wash down pumps provide the perfect wash down solution for cleaning recreational equipment. With a higher pressure of up to 5 bar, clean-up is faster and easier than ever before. The pump is equipped with positively checking outlet valves which ensure that the pressure is maintained after the pump shuts off. When water is demanded the pressure decreases. After a moderate drop in pressure, the integrated pressure switch automatically turns the pump back on.
