The Flanged Alloy EWP80 is available for purchase in following options:

  • Pump Only (12V)
  • Kit (12V)
  • Combo with Controller (12V)
The EWP®80 Flanged Alloy Electric Water Pump and LCD EWP/Fan Digital Controller Combo – 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. This compact pump is manufactured out of lightweight Aluminium and utilises 6 bolt flange fittings on both the inlet and outlet of the pump for superior fitment flexibility. The provided 35mm (1-3/8”) straight and right-angle push on barb fittings offer convenient fitment in any application.

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.
EWP115
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.
EWP130/EWP140
Suitable for most engines up to around 400bhp, particularly where space is tight, as it shares the EWP80’s flexibility in mounting configurations.
EWP150
Suits very high powered engines, race cars, very hard-working 4x4s, many commercial vehicles etc. All EWP150s have alloy bodies.
