The Whale Premium Inline Booster Pump 13LPM 12V GP1392 is a compact, quiet and energy-efficient water pump designed to improve water flow in caravans, motorhomes and boats, featuring self-venting operation, 12V power and compatibility with pressure-switched and microswitched systems.
Designed to enhance the performance of existing freshwater installations, this practical Whale booster pump provides an economical solution for increasing water flow to taps and other suitable outlets. Its maximum flow rate of approximately 13 litres per minute makes it particularly useful for leisure vehicles requiring additional water delivery from their existing pump arrangement.
The inline booster design allows the GP1392 to be installed directly into compatible water pipework. It is designed to work alongside a suitable submersible electric pump or manual foot pump, helping improve the flow available throughout the system without requiring a larger primary pump.
One of its standout advantages is its self-venting construction, which helps release trapped air during operation. This supports more consistent water delivery and reduces the inconvenience associated with air accumulating within the pump.
The Whale Premium Inline Booster Pump is also designed for quiet operation and low power consumption, making it suitable for caravans and motorhomes where electrical efficiency and minimal noise are important. Operating from a standard 12V DC supply, it draws approximately 3.6A at its rated maximum flow.
Its compact dimensions of just 135mm in length and 38mm in width make installation convenient in restricted spaces. Weighing approximately 150g, the pump can be fitted neatly into suitable pipework without requiring a separate mounting bracket.
The GP1392 is compatible with 10mm and 13mm internal diameter flexible hoses, with 13mm adaptors supplied. This provides flexibility when integrating the pump into different caravan, campervan and marine freshwater installations.
Another useful feature is its compatibility with microswitched taps, pressure switches and separate electrical switches. This allows the pump to operate within a variety of correctly configured water systems.
The pump delivers approximately 11.75L/min at a 1m head and 9.75L/min at a 3m head, providing useful performance for everyday washing, rinsing and freshwater supply.
