EWP115 Nylon - 12V 115LPM/30GPM Remote Electric Water Pump (PART #8125)

The EWP115 Nylon 12V is available for purchase in following options:

• Pump Only (Part #8125) 
• Kit (Part #8025)
• Combo with Controller (Part #8930)

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).

  EWP & CONTROLLER INSTALLATION DEMONSTRATION

Combined with an LCD EWP/Fan Digital Controller (Sold separately Part #8002 or combo #8930) , 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.

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.

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.
