EWP115 Alloy Combo - 12V 115LPM/30GPM Remote Electric Water Pump & Controller (Part #8950)

The EWP115 Alloy12V is available for purchase in following options:

• Pump Only (Part #8140) 
• Kit (Part #8040) 
• Combo with Controller (Part #8950)

Take total control of your engine cooling with the Davies Craig EWP115 Alloy 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 accessory that improves engine cooling control and capacity whilst giving you more power and torque and improved fuel economy.

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 Alloy 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 EWP115 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)

EWP INSTALLATION OPTIONS

Installing 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. Re-install ensuring that the thermostat housing is clean and a new gasket is used if required.

In both these cases, the EWP will pump past the impeller of the mechanical water pump.

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 ensuring that all gasket surfaces are clean and the new gaskets are properly fitted to prevent leaks.
• Install the EWP^Ò into the bottom radiator hose.

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). Ensuring the gasket surfaces are clean and the appropriate gasket or sealant is used to prevent leaks.
• Install the EWP into the bottom radiator hose. This method will require you to modify or replace the standard radiator hose.
• Install an appropriate length belt (not supplied) to drive the accessories.

In most cases EWP will be adequately supported by the radiator hose. Where mounting is required, the EWP must be soft mounted to protect against vibration. For the EWP115, EWP130 and EWP150 Part #8700 Mounting bracket is recommended.

  

EWP & FAN DIGITAL CONTROLLER - 12 & 24 VOLT
This LCD EWP / Fan Digital Controller (Part #8002) 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 40°C (104°F)to 110°C (230°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.
