    Take total control of your engine cooling with the Davies Craig EWP115 Aluminum Electric Water Pump and LCD EWP/Fan Digital Controller. The Controller will also manage the operation of your Thermatic Fan. The EWP115 (115 litres per minute) pump is suitable for small, medium, large, high-performance and 4WD vehicles. It’s a performance product that improves engine cooling control and capacity whilst giving you more power and torque and improved fuel economy.

    The LCD EWP/Fan Digital Controller 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. Multiple temperature settings are provided on the Controller for either maximum power or fuel efficiency.

    The Thermatic Fan/s will be activated automatically once the engine coolant rises 5.4°F (3°C) above the targeted (set) temperature. The Digital Controller will automatically run on for three minutes (or to 14°F / 10°C below the set temperature) after engine shut down, eliminating ‘heat soak’ and extending engine life.

    The EWP115 Digital Controller Combo is supplied in a do-it-yourself kit with everything you need for fitment to your vehicle’s engine, including an easy-to-follow DIY instruction booklet.

    The EWP115 (115 litres per minute) pump is suitable for small, medium, large, high- performance and 4WD vehicles. It’s a performance product that improves engine cooling control and capacity whilst giving you more power and torque and improved fuel economy.

    The EWP115 is a practical alternative to the mechanical belt-driven pump or fitted as an auxiliary pump. Mechanical belt-driven water pumps run directly off the motor and sap engine power … the EWP115 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. This kit comes 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.

    An Electric Water Pump is one of the most economical way to increase horsepower and save on fuel consumption whilst caring for your engine. Used in conjunction with a Davies, Craig EWP header adaptor kit, it can replace the mechanical water pump completely.

    The mechanical water pump is one of the last mechanical components of the modern engine which has long been considered an inefficient component that was designed as an accessory from the very first engines. A mechanical belt driven pump installed on your car engines runs at the same speed as the engine regardless of how hot the engine is. Example: when traveling at high speeds down the freeway, the engine require less cooling as ram air is naturally cooling the engine however, the engine speed is high as is the mechanical water pump thus providing excessive cooling whilst draining the engine of power. Then in heavy traffic in high ambient, the engine is idling or slow and so is the belt driven mechanical pump, even though in this condition, extra coolant flow is required to cool the engine.

    With an LCD EWP Controller, the speed of the pump is managed by the controller, which varies the supply voltage to the pump and so varies the speed of the pump, hunting for a target temperature. When the engine reaches the target temperature the controller locks on, constantly changing the pump speed with traffic and throttle conditions, maintaining the target temperature independent of the engine speed.

    The important improvement for your vehicle comes from the fact that most of the power the mechanical pump takes from the engine can be reclaimed with the use of an EWP hence the fuel savings. By removing the parasitic power losses of belt-driven water pumps, the EWP may provide up to 10kw of extra power and additional fuel savings. The engine power used by the mechanical pump increases as the cube of its speed – so when the mechanical pump speed doubles from idle speed say; 600 rpm to 1200 rpm, the power it takes increases by eight times. Then another eight times going to 2400 rpm, and so on up to maximum engine speed. It is this extra power and torque that is released by deleting the mechanical pump that provides the fuel savings that is estimated to be 3.5% to 10%.

    Major European Manufacturers have implemented EWP's as standard issue on a number of their vehicles, it has been documented to show that and EWP uses 90% less energy than conventional systems, i.e.: the mechanical water pump. Other advantages will include lower emissions by virtue of faster engine warm up, better engine temperature management, eliminating engine heat soak and improved engine life.

    Weight reduction is a key requirement of any automotive manufacturer seeking fuel savings and our EWP will weight around 900 grams up to 1,151 grams (dependent on EWP Type) compared to a typical mechanical pump at 3 to 4 kg. Not only is their EWP considerably lighter when matched against the mechanical pump but it would also be replacing several outdated components with one environmentally friendly product which once again helps improve performance and fuel consumption.
