EWP80 Alloy Flange Kit - Remote Electric Water Pump (12V)
The EWP®80 Alloy Flange is available for purchase in following options:
- Pump Only (Part #8106)
- Kit (Part #8006)
- Combo with Controller (Part #8908)
The EWP®80 Alloy Flange Kit configuration mirrors the highly successful EWP®80 Nylon pump. It provides a maximum flow rate of 90 l/min and will fit most vehicle engines up to two litres as an alternative to the mechanical belt-driven pump or as an auxiliary pump.
This compact pump is manufactured out of lightweight Aluminium and utilises 6 bolt flange fittings for superior fitment flexibility. Arriving in a magnificent matt-black powder-coated finish, it removes parasitic power losses, providing up to 10kW (13hp) of extra power and increased torque. Used extensively in Intercooler applications.

Combined with an LCD EWP®/Fan Digital Controller (Sold separately Part #8002 or EWP® Combo Pack) will manage both the EWP® and Thermatic® fan operation. The Digital Controller will vary the speed of the EWP® in response to the engine’s coolant temperature.
universal fit more power more cooling increase fuel efficiency extend engine life world-leading technologyInstalling an EWP® as an AUXILIARY PUMP
- Leaving the mechanical water pump in place, install the EWP® into the bottom radiator hose.
- Remove the thermostat and drill two approx. 3mm (1/8") holes in the thermostat plate to allow some coolant circulation when the thermostat is closed. Re-install ensuring that the thermostat housing is clean and a new gasket is used if required.
EWP® installation – disabling Mechanical water pump
- Leaving the mechanical water pump in place, install the EWP® into the bottom radiator hose and remove the manufacturer’s thermostat.
- You will need to bypass the water pump pulley by installing an appropriate length belt (not supplied). This method makes for an easy installation.
- If running the pump continuously remove the thermostat and drill two approx. 3mm (1/8") holes in the thermostat plate to allow some coolant circulation.
Disengaged mechanical water pump (recommended)
- Remove the mechanical water pump and remove the thermostat.
- Then remove the impeller from the mechanical pump shaft. Retain the mechanical water pump using the pump pulley as an idler to avoid re-routing the drive belt.
- Block any bypass passages and re-install the disengaged water pump.
Removed mechanical water pump (Ideal)
- Remove the mechanical water pump and thermostat from the engine.
- Install a Davies Craig EWP® Header Adaptor or blanking plate (not supplied).
- Install the EWP® into the bottom radiator hose. This method will require you to modify or replace the standard radiator hose.
In most cases EWP® will be adequately supported by the radiator hose. For the EWP®115, EWP®140 and EWP®150 Part #8700 or #8710 Mounting bracket is recommended.
