The EBP23 is available for purchase in following options:

The EBP23 is a ‘brushless’ 12 volt, high flow (23 litres / 6 gallons per minute), magnetically driven water pump. The EBP motor has no brushes to ever wear out and the pump is magnetically driven by the motor, which means that no shaft sealing is required. The many EBP applications include: booster for car heater and LPG systems, solar pump applications, water cooled motorcycle, go-kart engines, turbo air / water intercoolers & household irrigation.

The EBP®23 is designed to complement your existing Davies, Craig EWP (Electric Water Pump), or belt-driven mechanical water pump, or improve your heater and/or cooling system or assist engine block cooling circulation. The EBP can continually circulate coolant around the engine head, block and by-pass. It has a high flow capacity and has the advantage of running at a speed independent of the engine speed. The EBP® can also be set to continue running with a timer or thermal switch (not supplied) after engine shut down to prevent damaging heat soak.

Electric Booster Pump Comparison chart

Use for thermosyphon cars, boosting car heater performance, liquid-cooled motorcycles and scooters up to 500cc, and other low powered closed-circuit cooling systems eg hovercraft, lawnmowers. Also suitable for Larger-engined motorcycles 500cc-1000cc. Air-to-water intercoolers for turbos & superchargers.
Higher powered motorcycles and lower powered kit cars. Air-to-water intercoolers for turbos & superchargers. Significantly better flow rates than the EBP23 when resistance to flow is higher, eg with long hose runs.
Very high powered / race motorcycles, intercoolers, solar heating systems etc (12V & 24V)
