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, 1/2NPT/Hose 3/4, 1/2 NPT, 3/4 HoseWeight: 2 kg /4.5lbsLength: 236,5 mm/9.31Width: 210 mm/8.25Height: 116 mm/4.575
