Description
12 Volt Self Priming Diaphragm Pump 17L/M 003
Reliable Water Pressure for Caravans, Boats & Off-Grid Living
Enjoy convenient running water wherever your adventures take you with the 12 Volt Water System Pump. Designed for caravans, camper vans, boats and off-grid water systems, this compact automatic water pump makes it easy to supply water to taps, showers and other compatible outlets without relying on mains electricity.
With a maximum flow rate of 17 litres per minute and pressure of up to 40 PSI (2.75 bar), this pump provides a practical solution for mobile water systems that need reliable water pressure.
One of its most convenient features is the built-in automatic pressure switch. When you open a tap, the pump automatically starts supplying water. Once you close the tap and pressure builds up, the pump switches off, helping save energy and making everyday use easier.
The pump is also self-priming up to 1.5 metres, allowing it to be installed above your water tank under suitable conditions.
Whether you're setting up a camper van, upgrading your caravan's water system or installing a water supply on your boat, this 12V pump offers a convenient way to keep water flowing.

Thanks to its built-in 40 PSI automatic pressure switch, there's no need to manually switch the pump on and off every time you need water.
Simply open your tap and the pump starts supplying water. When you close the tap, pressure builds up in the system and the pump automatically switches off.
This makes it particularly convenient for mobile showers, kitchen taps and other everyday water supply applications.

Powering Your 12V Water System Pump
This pump operates on 12V DC, making it suitable for mobile and off-grid water installations.
It can be powered using:
-
12V Battery: Ideal for caravans, boats, camper vans and camping setups.
-
Solar Power: Can operate as part of a properly designed solar system using a suitable solar panel, regulator and battery.
-
Regulated 12V DC Power Supply: Suitable for installations with a compatible AC-to-DC power supply.
Please note: The battery, solar panel and regulator are not included with the pump.
Important Installation & Operating Information
This pump is designed for intermittent operation and should not be used continuously.
To protect the motor and extend the lifespan of the pump:
-
Maximum Running Time: Do not operate continuously for longer than 30 minutes.
-
Cooling Period: Allow at least 15 minutes between operating cycles, and ensure the pump has cooled to ambient temperature before restarting.
-
Secure Pipe Connections: All piping and fittings must be properly connected and sealed.
-
Prevent Leaks: Leaks can cause the pressure switch to cycle on and off repeatedly, potentially shortening its lifespan.
-
Thermal Protection: The motor features thermal overload protection and may restart automatically after cooling.
-
Correct Power Supply: Always use a suitable 12V DC power source capable of supplying the required current.
-
Dry-Run Protection: Although the pump includes dry-run detection, it should not be intentionally operated without water.
For best performance, install the pump according to the manufacturer's instructions and ensure your water system is properly sealed.
