SEAFLO RV Supreme MK2 12V Water Pump 55 PSI RV1-030-055-42

Open a tap, it starts. Close it, it stops. The SEAFLO RV Supreme MK2 is the 12V on-demand pump most AU vans and small boats already know — RV1-030-055-42, 42 Series, four-chamber diaphragm with internal bypass so it does not hammer the pipes every time you crack a tap.

3.0 GPM / up to 11.3 L/min, shuts off at 55 PSI (3.8 bar). Self-primes to 1.8 m. Run-dry safe. Quiet on a rubber base that matches the industry mounting pattern, so it drops in where a tired Shurflo or older SEAFLO sat.

Kit in the box: pump, inlet filter, and three 1/2" fittings. Fresh water only — caravan, RV, food van, boat galley.
