SEAFLO 33 Series RV Water Pump, 12V, 3.0 GPM 45 PSI Diaphragm Pump, Self Priming On Demand, NSF UL
SEAFLO's 33 Series 12V RV water pump, 3.0 GPM at 45 PSI, self priming and on demand with NSF and UL listings.
When you are dry camping, the water pump is what gives you a working sink and shower, and the noisy, weak units many rigs ship with make every dish and rinse a chore. Upgrading to a stronger, quieter pump brings near-residential water pressure to your rig without needing a city hookup. Below we compare 12V RV water pumps on the specs that matter in daily use. We look at flow rate and pressure for a satisfying shower, how quiet each runs when it kicks on at night, self-priming reliability, and whether the fittings and dimensions match common factory installs so the swap stays straightforward.
