Relaxn Fresh Water Pump 19 LPM 60 PSI 12V 5 chamber with bypass

BP1912 is the high flow 12V diaphragm pump, 19 litres per minute at 60 PSI, for vans and vessels with several outlets that can run at the same time. The five chamber layout is what smooths the delivery: more chambers means smaller pressure pulses per revolution, so a tap does not surge. An integrated bypass minimises spikes and cycling, and the pump is self-priming, which keeps the installation simple when it sits above the tank.

Key features

• Flow rate 19 LPM
• 60 PSI pressure rating for higher demand systems
• Five chamber diaphragm design for smooth, stable flow
• Integrated bypass to minimise pressure spikes and cycling
• 12V DC operation for mobile power setups
• Self-priming
• Stock code BP1912

Applications

• Larger caravans and motorhomes with multiple outlets
• Fresh water systems on cruising and cabin boats
• Vans with a shower, galley and outside tap
• Mobile and off-grid water delivery systems
• Installations where a smaller pump is already struggling

Compatibility and fitting

• Use drinking water rated hose on both sides of the pump; see beverage and food hose
• Fittings and push-fit plumbing are under caravan plumbing fittings
• The smaller BP1112 at 11 LPM and 55 PSI is on water pumps

How do I choose between 11 LPM and 19 LPM?

Count the outlets that could run together. One tap and a shower used separately suits the 11 LPM BP1112; a shower plus a galley tap plus an outside shower wants the 19 LPM BP1912. Pressure is close either way, 55 PSI against 60 PSI, so flow is the deciding number.

Does a bigger pump use more battery?

It draws more while running, but it also refills the system faster and spends less time running. In practice the difference over a day is smaller than the comfort gained at the outlets.
