Aqua Jet Water Pressure Systems – 4.0GPM – 12VThe five chamber Aqua Jet WPS-series provides a reliable heart for small boat and recreational vehicle water pressure systems. Compared to conventional three or four-chamber diaphragm pumps, the Aqua Jet demonstrates dramatically lower noise and water pulsation characteristics. It is recommended to install the WPS-pumps with an accumulator tank. Always use a PUMProtector inlet strainer before the pump intake.Diaphragm: SantopreneValves EPDMBody: Nylon/PolypropyleneMotor: 100WPressure Cut Off:2.8 bar – 41psiFuze Size: 10 AConnection:3/8″ NPT/hose 1/2″, 1/2″NPT/Hose 3/4″, 1/2″ NPT, 3/4″ HoseWeight: 2 kg /4.5lbsLength: 236,5 mm/9.31″Width: 210 mm/8.25″Height: 116 mm/4.575″
