Feature: 1. Characteristic: Our diaphragm pump is self priming with a pressure of 60PSI, 4.2 BAR and a flow rate of 18.9LPM, 5.0GPM, allowing for short dry runs, reliable performance, and low current. 2. High Flow Rate: This 5 chamber construction design eliminates the need for a pressure tank and can be installed to provide a high flow rate with up to five 13 mm (1/2 in) outlets. 3. Wide Applications: Diaphragm pump is suitable for water systems connected to tanks and are commonly used in yachts, RVs and mobile passenger cabins. The flow rate can reach 19L per minute. 4. Automatic Switch: Automatic start technology, with both pressure switch and return switch control, the pump starts automatically when the tap is opened and stops automatically when the tap is closed. 5. Noise Reduction and Anti Vibration: Rubber soft pads are installed at the corners of the base, which can largely reduce vibration even on a hard exterior, and the 5 chamber body reduces the number of pump operations, reduces noise and runs quietly. Specification: Item Type: Self Priming Pump Material: Engineering Plastic + Metal Working Voltage: 12V Operating Current: 6A Pressure: 60PSI, 4.2BAR Flow Rate: 18.9LPM, 5.0GPM Maximum Peak Current: 15A Drive Mode: Electric Control Method: Pressure Switch Operating Mode: Continuous Operation Function: With self priming function Can run dry for a short time Main Uses: Yacht water supply system pressurization, caravan water supply system pressurization, dynamic car water supply system pressurization, large electric sprayer, vehicle mounted sprayer, washing machine, heater, drinking fountain, medical equipment and other supporting equipment to be pressurized.
