12V Diaphragm Water Pump with Automatic Pressure Control, Pressure for Boat Bilge and Car Wash

Diaphragm Water Pump, Color Reflux A compact 12V DC diaphragm pump designed for applications that require frequent switching and automatic pressure control. Built with durable materials and vibration mounting, it reduces power use during standby and restarts automatically when flow demand returns. Key benefits Automatic pressure control: optional pressure switch or reflux switch cuts power when outlet pressure reaches the set level and restarts when pressure falls, allowing reliable automatic on and off operation. Energy efficient for frequent cycling: suited to systems that need repeated start and stop, reducing wasted run time. Sturdy connections and vibration isolation: inlet and outlet use silica gel PE or PU pipe connections and the pump has soft rubber mounting feet for vibration cushioning. Compact and serviceable: small footprint and straightforward installation for a range of water transfer tasks. Main specifications Color: Reflux Voltage: 12V DC. Note 220V AC can be used with a transformer Current: 6 A Rated power: 72 W Pressure: 7 kg Flow rate: 6.0 liters per minute Medium temperature range: 0 to 100 C Water inlet and outlet size: 20 mm Size: 16.5 x 10 x 6.2 cm Type: pressure switch or reflux switch optional Package includes: 1 x diaphragm pump Materials and performance Diaphragm design provides stable flow and tolerance to on off cycling Pipe connections use silica gel PE or PU for reliable sealing Soft rubber feet reduce vibration and noise transmission Pressure switch function protects against run on when output pressure is sufficient Typical applications Machine washing systems where frequent pump start and stop is required Solar water feeding or circulation systems that need a low voltage pump and automatic pressure control Remote or automatic water transfer and suspension supply systems that require reliable on off operation Notes Manual measurement tolerance 1 to 3 mm Actual product color may vary slightly from images due to monitor differences If using 220V AC supply, a transformer is required to run the 12V DC pump
