The EWP150 Alloy Electric Water Pump – univresal fit, do-it-yourself, easy to install water pump designed to replace or compliment your existing belt-driven mechanical water pump. By removing the parasitic power losses of a belt-driven water pump the EWP can provide up to 10kW of extra power, increased torque, increased cooling capacity, eliminating heat soak and provide better engine temperature control.

This high capacity EWP®150 (40 US Gal/Min) is designed to replace and/or complement the existing belt driven mechanical water pump and when fitted with the optional Digital Controller (Part # 8020), replaces the thermostat.
The major benefits a EWP®150 offers are:

> Minimise the parasitic power losses running a mechanical water pump at high speed when not needed
> Maximise engine warm-up & minimise the effects of heat soak by operating the EWP®150 after engine shut down.

The EWP®150 has the advantage of offering more consistent coolant flow independent of the engine revs. The fitment of the EWP® & Fan Digital Controller to your engine, which is scientifically calibrated to manage the volume/flow of engine coolant with the corresponding increase in coolant temperature within the engine’s cooling system.

From start-up, the EWP® & Fan Digital Controller will ‘system check’ the EWP®150 and Thermatic Fan operating the pump and fan for approx. 10 seconds. Low engine temperature, low flow (10-on – 30-off pwm) reduces engine warm-up time, arriving at your targeted/set temperature quicker, assisting control the engine temperature within your -5 to +3 degree targeted/set temperature range. The Electric Thermatic Fan/s will be deployed at +3◦C above targeted/set temp if slower travel (traffic) or engine idle conditions continue. The EWP® & Fan Digital Controller will continue operating after a hot engine shut down for a approx. 2 minute period to help prevent damaging heat soak.


Davies Craig Pty Ltd is very pleased to announce the arrival of the updated Liquid Crystal Display (LCD) EWP®/Fan Digital Controller!

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.

These include:
• The prominent blue Liquid Crystal Display screen (pictured)
• Now suitable for all 12v & 24v electrical systems, with relevant displays
• Genuine Thermometer, with coolant and targeted/set temp. displays
• Diagnostic check & warm-up signals
• Nine (9) targeted/set coolant temperatures, 60C (140F) to 100C (212F)
• Flashing “EWP®” logo signifying water pump in operation
• Davies Craig Thermatic® Fan logo, circulating signifying fan in operation
• Flashing High & Low Voltage indicators
• Low & High Temp indicators
• Audible alarm –
* if coolant temp doesn’t exceed 40ºC (104ºF) within 5 mins of start-up
* when coolant temperature exceeds 10ºC (50ºF) of set/target
* when coolant temperature exceeds 100ºC (212ºF)
• Above Set/Target Temperature indicator accompanies audible alarm
• Temperature Sensor short & open circuit indicators
• Automatic time-out, EWP® runs for 3 minutes or until engine temp has reduced to -10◦C (-14F) below set/targeted temp whichever occurs first.

The updated Davies, Craig LCD EWP®/Fan Digital Controller (#8000) as an engine management component has undergone extensive research, development, vehicle and test centre scrutiny.

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, 60ºC (140°F) 65ºC (150°F) 70C (160°F) 75ºC (165°F) 80ºC (175°F) 85ºC (185°F) 90ºC (195°F) 95ºC (205°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.

The LCD Digital Controller can be used with our EBP however it is not recommended as it will not vary the speed of the pump in response to temperature but rather simply turn the pump on and off once the top end temperature is reached. For a far more economical & appropriate solution, we would recommend Part Number 0401 & 0444 to turn the EBP on and off at your set temp.
