The R4320-243 Flojet quad pump is no longer available and has been removed from sale. We have an alternative in the 4300-143 and a 240v to 12v DC transformer which produces a maximum flow of 17.8 L/min and is fitted with an automatic pressure switch that is set at 245 kPa (30 psi). It comes with 20mm hose barb inlet and outlet ports and has santoprene diaphragms and EPDM check valves so it is suitable for water and some dilute chemicals. This is a great pump for a pressure water supply to a mobile home, boat or weekender. This pump is supplied as a 12v DC pump with a 240AC to 12v DC transformer. Click here for the pdf spec sheet.
