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.

Why You'll Love It

  • Automatic On-Demand Operation: The built-in pressure switch starts and stops the pump as you open and close your taps.

  • Powerful 17 L/min Flow Rate: Delivers a maximum flow of 17 litres per minute for compatible water supply systems.

  • Up to 2.75 Bar Pressure: Provides useful water pressure for taps, showers and mobile water installations.

  • 12V DC Operation: Ideal for battery-powered and off-grid water systems.

  • Self-Priming Design: Can draw water from a tank up to 1.5 metres below the pump under suitable conditions.

  • Built-In Pressure Switch: Automatically switches the pump off when the system reaches 40 PSI.

  • Thermal Overload Protection: Automatically stops the motor if it overheats, with an automatic restart function once conditions allow.

  • Dry-Run Detection: Includes protection designed to detect dry-running conditions.

  • Quiet Operation: Designed to minimise noise during use.

  • Replaceable Pressure Switch: Allows the pressure switch to be replaced when required.

  • Spare Parts Support: Replacement parts are supported for easier maintenance.

  • Versatile Installation: Suitable for caravans, boats, camper vans and other compatible 12V water systems.

Automatic Water Pressure Made Easy

The 12 Volt Water System Pump takes the hassle out of managing water pressure in your caravan, boat or off-grid setup.

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.

Ideal Applications

  • Caravans & Motorhomes: Supply water to taps, basins and compatible shower systems.

  • Camper Vans: Create a convenient pressurised water supply for travelling and camping.

  • Boats: Provide automatic water pressure for onboard freshwater systems.

  • Off-Grid Living: Operate from a suitable 12V battery or regulated solar-powered system.

  • Camping Water Systems: Supply water from portable tanks and storage containers.

  • Mobile Water Installations: Ideal for applications requiring an automatic low-voltage water pump.

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.
