Celebrating 50 years, Davies Craig Pty Ltd is launching a ‘BLACK LABEL’ Limited Edition EWP®150 Remote-Mounted Electric Water Pump! This attractive model is supplied in glorious matt black power-coat.
Upgrade your cooling system with the EWP®150 Alloy Electric Water Pump (12V) — a high-flow, remote-mount solution engineered for performance vehicles that demand superior temperature control.
Delivering a massive open flow rate of 162 litres per minute (42.8 g/min), it is designed for high horsepower, turbocharged, supercharged and modified engines. The EWP®150 efficiently manages excessive heat while also supporting intercooler applications. By reducing the load on your engine compared to a traditional mechanical pump, it helps free up power and improve overall efficiency.
The EWP® Combo Configuration is the ideal solution for a full electric water pump conversion. This setup allows you to remove or disengage the mechanical belt-driven water pump and, in most applications, eliminate the factory mechanical thermostat — delivering precise, fully controlled cooling system performance.
By converting to an EWP® Combo system, you gain optimal temperature management, improved efficiency, and complete control over your engine’s cooling strategy.

The updated LCD Digital Controller manages the operation of the EWP® by varying the speed of the pump in response to engine temperature and manages your electric engine fan.
Features:
Black & White Numerical Screen
Celsius or Fahrenheit display option
Set / targeted temperature memory
Override feature to assist bleeding EWP®
Warning Alarms:
- Plus 10°C (14°F) set/target temperature
- Under temp 40°C after 5 mins
- Temp sensor error / Over or under voltage / EWP® error
Combined with an LCD EWP®/Fan Digital Controller (Included in this Combo Pack) 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.

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.
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® 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 EWP®115, EWP®140 and EWP®150 Part DC8700 or DC8710 Mounting bracket is recommended.
