The EWP®80 Alloy Electric Water Pump – simple, do-it-yourself, easy to install, designed to complement or replace your existing belt-driven, mechanical water pump. It will fit most vehicle makes and models fitted with naturally-aspirated or turbo engines up to two litres. The revolutionary, Australian-designed EWP®80 Alloy is made from lightweight aluminium which offers great thermal conductivity and incorporates a ceramic faced seal for long-life durability.

The EWP®80 greatly enhances engine cooling control while giving you added power and improved fuel economy. By removing the parasitic power losses of a belt-driven, mechanical water pump the EWP® can provide up to 10kW (13hp) of extra power and increased torque and used extensively in Intercooler applications.

Electric Water Pump Comparison chart

EWP80 Nylon & Alloy
Most small- and medium sized car engines, up to around 2.5 litres/200HP. The EWP80 is the most flexible pump in terms of mounting configurations.
For higher power and tuned engines in the 200-350HP range. Available with either glass-filled nylon or alloy body. The performance of the two pumps is identical, but the alloy pump can be hard mounted and so is more suitable for rough treatment eg in rally cars.
Suitable for most engines up to around 400bhp, particularly where space is tight, as it shares the EWP80’s flexibility in mounting configurations.
Suits very high powered engines, race cars, very hard-working 4x4s, many commercial vehicles etc. All EWP150s have alloy bodies.
