Intelligent pump to revolutionise engine cooling
Davies, Craig will launch its patented third-generation EWP electric water pump and electronic smart controller in May 2004.
Water pump adds new generation controller
The release of the new generation electronic controller for the innovative Davies Craig EWP electric water pump gives drivers an instant choice between power or economy at the press of a button.
All internal parts of the EWP exposed to coolant are stainless steel and the higher power electric motor has sealed bearings, with the pump body and impeller being made from heat stabilised glass-filled nylon.
This improved pump is now fully serviceable.
Performance-conscious drivers can now take advantage of the EWP power gains, confident that the unit will provide years of trouble-free service while improving vehicle performance, fuel economy and cooling management.

Electric water pumps optimise 4WD cooling
Davies Craig has had a number of enquiries recently with respect to large 4WDs overheating - particularly when towing on long gradients.
"We've put in considerable investment to upgrade the design, features and production methods that make this generation three model the very best EWP", says Davies Craig's Ray Brown.
"It's now a truly world class unit from every point of view".
In the short time this innovative solution to vehicle cooling has been on the market it has proven to be successful in the performance sector (cooling the class winning Ferrari at LeMans) and is attracting increased attention from automotive manufacturers for adoption as original equipment.
By installing the EWP, users will not only improve the cooling efficiency of their vehicle but also have the immediate benefits of enabling the engine to transmit power, which used to operate the outdated belt-driven water pump, to the road.
Power gain for a typical 4 litre engine can be up to 8kW.
Matched with the electronic controller, the EWP provides optimum cooling performance management independent of engine speed for maximum performance.
This smart device has a sensor that monitors the preset coolant temperature and regulates the EWP speed to match demand.
An example of this enhanced operation is the way the controller keeps the EWP turning after the ignition has been switched off to control engine cooling after a hot shutdown.
Converting a vehicle is as easy as removing the lower radiator hose together with the thermostat and disabling the mechanical pump.
The lower radiator hose is then cut for the EWP to be fitted inline, assisted by the many universal fittings included in the standard kit.
The compact controller is easily installed and the temperature sensor is fitted to the top radiator hose or thermostat housing.
The rest is all long-term performance improvement.
