Jabsco ParMax 2 Diaphragm Pump 1/2 Inch 12V – 31295-3512-3A

The Jabsco Par‑Max 2 is a compact 12 V freshwater pressure pump designed for reliable water delivery in boats, RVs, and motorhomes. Ideal for supplying on‑demand water to sinks, showers, and multiple outlets in mobile living environments, it delivers smooth, consistent flow where space and power are limited.

Built for durability and quiet operation, this pressure‑controlled diaphragm pump provides approximately 7.6 L/min (2 GPM) open flow and has a max operating pressure 25 PSI (1.7 bar) while automatically starting and stopping via its integrated pressure switch. Its three‑chamber Santoprene diaphragm with EPDM check valves ensures long life and smooth flow, and self‑priming and dry‑run capability allow flexible installation without damage if briefly run empty. 1/2″ (13 mm) quick‑connect hosebarb ports with a 40‑mesh inline strainer simplify plumbing, and vibration‑reducing mounts help keep operation quiet and smooth.
