12V Camping Water Pump with Self-Priming Design by Seaflow

Running a tap or shower off the grid comes down to one thing: a reliable 12V camping water pump wired straight into your battery system. This Seaflow diaphragm pump delivers 3.8LPM at up to 40PSI, enough for a single sink or shower point in a caravan, camper trailer, boat or 4x4 camp setup, and it switches on the moment a tap opens.

A built-in pressure switch handles the start and stop automatically, so there's no separate control to wire in. The self-priming design pulls water up to 1.2m of suction lift, which means the pump can sit above the tank rather than needing gravity feed, and a sealed thermal protector guards the motor if it runs hot. It's also rated to run dry without damage, handy while you're still plumbing the system in.

3.8LPM Flow Rate

40 PSI Maximum Pressure

1.2m Suction Lift

Features

12V DC Operation: Runs straight off a vehicle, caravan or deep-cycle leisure battery, no mains power needed at camp.

3.8LPM Flow Rate: Enough for a single tap, shower rose or sink line.

40 PSI Maximum Pressure: Keeps consistent pressure at the tap rather than a trickle.

Self-Priming to 1.2m Suction Lift: Mount it above the tank and it still pulls water through.

Automatic On-Demand Switch: On when a tap opens, off when it closes.

Dry-Run Capable: Tolerant of an empty line while you finish plumbing it in.

Thermal Protection: Built-in thermal protector guards the motor during use.

Compact and Quiet: Fits tight cavities and runs quieter than a typical 12V pump.

Frequently Asked Questions

How many taps can this pump run at once?

At 3.8LPM, this pump suits a single tap, shower rose or sink outlet running at a time.

Does the pump need mains power, or can it run off a battery?

It runs on 12V DC, wiring directly into a vehicle, caravan or deep-cycle leisure battery circuit. No mains power or inverter is needed. We'd recommend a qualified auto electrician handle the wiring into your system.

Can the pump run dry without being damaged?

Yes, it's designed with dry-run capability, so an empty line during installation or a temporarily empty tank shouldn't damage it under normal use.

Does the pump need to be primed before use?

It's self-priming, rated to pull water through up to 1.2 metres of suction lift, so there's no need to manually prime the line on startup.

Can the pump be mounted above the water tank?

Yes. Its self-priming design and 1.2m suction lift rating mean it can be installed above the tank rather than needing a gravity feed.

Will the pump run continuously, or only when a tap is open?

It's built for intermittent, on-demand operation. The built-in pressure switch starts it when a tap opens and stops it once pressure builds back up.

What size hose fits the pump's inlet and outlet?

The inlet and outlet are 3/8 inch hose barb fittings.

How is the pump wired in?

It comes with 18 AWG power leads, approximately 35cm long, terminating in a 2-pin connector. We'd recommend a qualified auto electrician wire it into your battery or accessory circuit.
