The Whale Standard Submersible Pump GP1002 is a compact and efficient 12V electric water pump designed to deliver a reliable freshwater supply in caravans, motorhomes, campervans and boats. With a maximum flow rate of 10.3 litres per minute, this lightweight pump provides a practical solution for supplying water from external containers or onboard freshwater tanks.
Designed for everyday convenience, the GP1002 combines quiet operation, low power consumption and dependable performance. Whether you are replacing an existing submersible pump or upgrading a manual water system to electric operation, this genuine Whale pump offers an economical way to improve your freshwater setup.
One of its main advantages is its versatile electrical compatibility. The pump can operate with a microswitched tap, a separate electrical switch or a suitable pressure switch, allowing it to be incorporated into a variety of caravan and motorhome water systems.
Operating from a standard 12V DC power supply, the Whale GP1002 draws approximately 2.4 amps at its maximum flow rate. Its efficient design helps minimise demand on your leisure battery, making it suitable for touring and off-grid camping where power consumption is an important consideration.
The pump's compact dimensions make it particularly useful where space is limited. Measuring just 36mm in diameter, it can be lowered into suitable freshwater containers or installed within compatible onboard water tanks. Its narrow profile provides flexibility when working with smaller tank openings.
The Whale Standard Submersible Pump is designed to connect to 10mm or 13mm internal diameter flexible hose, providing compatibility with common leisure vehicle water system installations. Its 1m electrical cable allows connection to an appropriately protected 12V circuit.
Despite its compact construction, the GP1002 provides useful water delivery performance. It offers a maximum open-flow output of 10.3LPM, with flow reducing as the vertical pumping height increases. This makes it important to select the correct pump for your installation's required water flow and discharge height.
Manufactured using an ABS pump body, nitrile seals, polypropylene strainer and PBT impeller, the Whale GP1002 is designed for regular freshwater pumping applications. Its lightweight construction and straightforward design make it a convenient replacement or upgrade for compatible water systems.
Upgrade your caravan, motorhome or boat freshwater system with the Whale Standard Submersible Pump GP1002, combining reliable 12V performance, quiet operation and efficient water delivery in one compact pump.
