12V Diaphragm Water Pressure Pump, 1.2 GPM, 80 PSI

12V diaphragm water pump delivers steady 1.2 GPM flow for reliable pressurised water in RVs, caravans, boats and garden irrigation setups. The 2-chamber self-priming design reaches up to 10 ft, helping draw from tanks without pre-filling and supporting short dry-run starts. Built for quieter operation with reduced pulsation and vibration, it features a durable housing, protective cover and heavy-duty power cord for practical, quick installation.

• Delivers 1.2 GPM (4.5 L/min) max flow and up to 80 PSI for on-demand pressure


• Self-primes up to 10 ft to pull from distant tanks; supports short dry-run starts


• Reduces noise and vibration with a 2-chamber diaphragm and copper motor (approx. 50 dB)


• Connects to standard 3/8 in hoses with MNPT ports; clamps and sealing tape help prevent leaks


• Protects with built-in overheat and overload protection to reduce motor burnout risk
