Why Choose DC Autom
Dependable Off-Grid Water Pressure
Experience consistent water flow wherever you are with the SURGEFLO FL-44 24 V DC pump. Designed to outperform standard generic units, this robust pump delivers an impressive 17L/min flow rate at 40 PSI (2.8 bar). Whether you are upgrading a tired caravan water system or installing a new boat washdown setup, this pump ensures you never have to settle for a weak trickle again.
Smart Automatic Operation
Unlike manual pumps that require constant attention, our 40 psi diaphragm pump features a highly responsive built-in pressure switch. It automatically activates the moment you open a tap or nozzle and shuts off instantly when closed. Combined with integrated thermal overload protection, it is for intermittent clean-water duty, with thermal overload protection on the motor.

Whether you need a caravan water pump or a garden booster, the FL-44 24 V DC pump is built for intermittent clean-water duty.

Customer Reviews
Bought this as a boat freshwater pump for our narrowboat. The self-priming works perfectly right out of the box, and the pressure is fantastic for washing down the deck. Much quieter than our old unit.
An excellent caravan water pressure pump. Upgraded our old 7L/min pump to this 17L/min beast and the difference in the shower is night and day. Highly recommend for any motorhome owner.
I use this as a garden irrigation booster on my smallholding. It runs off a 24 V battery and gives steady pressure to the raised beds.
Great 40 psi diaphragm pump, delivers exactly the flow promised. My only minor gripe is that the power lead tails could be a bit longer for easier wiring, but it was simple enough to extend them.
I wanted a 24 V diaphragm pump for the van. The automatic shut-off is instant and it feels solidly built.
Using this in my mobile valeting van. The 17 lpm flow is brilliant for filling buckets quickly and running my low-pressure rinse hose. Good piece of kit, does exactly what I need.
Fantastic automatic dc water pump. Delivery was incredibly fast to Wales, and the build quality exceeded my expectations. The rubber feet really do stop the vibration noise transferring to the caravan walls.
