12V Diaphragm Pump for Mobile Water Systems

This 12V DC diaphragm pump delivers an open flow rate of 5.5 GPM and self-primes up to 6 feet. It operates at a rated pressure of 70 PSI with an adjustable range of 40 to 100 PSI. The unit draws 17A and consumes 216W, making it suitable for RV, camper, marine and lawn applications.

Five-Chamber Design with Santoprene Diaphragms

The pump uses five diaphragm chambers constructed from Santoprene material with EPDM valves. A pressure switch automatically starts and stops the motor when a faucet is opened or closed. The motor is rated for stable operation and supports dry running for short periods without damage.

PA6 Glass-Fibre Shell with FCC Certification

The housing is made from PA6 reinforced with 30% glass fibre for structural rigidity. Maximum liquid temperature is rated at 140°F (60°C) and ambient operating range spans 32 to 140°F (0 to 60°C). The product carries FCC certification and is not waterproof, so it must be installed in a protected location.

Questions about this item

How loud and hot does the 17 A motor run during continuous operation?

The manufacturer notes that if the pump shakes or gets loud, increasing water flow helps; it draws 17 A at 12 V (216 W) and is not waterproof, so it should be mounted in a ventilated, dry location.

What fittings and power supply are required to install the 1/2" MNPT ports?

The box includes two hose adapters, a 3/4" copper connector, sealing tape and a hex wrench; you must provide a 12 V DC source capable of 17 A and suitable hose or tubing for the 1/2" MNPT connections.

Will the Santoprene diaphragms and EPDM valves handle the same 140 °F liquid temperature as my old pump?

Yes, the maximum liquid temperature is rated at 140 °F (60 °C), and the Santoprene diaphragms with EPDM valves are designed for that range.
