Mechanical belt-driven water pumps run directly off the motor and sap engine power … the EWP®115 is hardwired into your electrical system, by-passing the engine and releasing up to an additional 10kw (13hp). Combined with the LCD EWP®/Fan Digital Controller, the pump continues to run after you’ve switched off, eliminating “heat soak” and extending engine life.

Davies, Craig’s revolutionary, Australian-designed EWP® pumps are made from anti-corrosive, lightweight nylon reinforced with fibreglass. Universal fit allows for easy mounting into the bottom radiator hose. Our kits come with easy-to-understand DIY instructions and everything you need for easy installation, including different adaptors to fit various hose sizes and all necessary electrical wiring.

The EWP®115 and LCD EWP®/Fan Digital Controller Combo Pack is the most economical way to increase horsepower and save on fuel consumption whilst caring for your engine.

The Davies, Craig EWP® header adaptor kit can replace the mechanical water pump completely. (See EWP Header Adaptors on website)

This LCD EWP® / Fan Digital Controller (Part #8000) is Australian designed and as part of this Australian manufacturing company’s continuous improvement program this advanced Digital Controller boasts a suite of enhancements.


The updated LCD Digital Controller how has two specific functions. This unique Controller will now manage the operation of the EWP® by varying the speed of the EWP® in response to the temperature of the engine and manage control of your electric engine fan. The Controller has a push-button on the facia panel that offers target temperatures Singular degrees from 60°C (140°F) to 100°C (212°F).

Generally, higher engine temperature will offer improved fuel efficiency and lower engine temperature more power. The LCD Digital Controller will now operate the engine’s electric fan automatically once the engine has reached +3c above the target temperature. A significant benefit too is the Controller allows the EWP® to run on after ignition shutdown to reduce heat soak. It is recommended that engine operational temperatures be checked with manufacturer.
