Davies Craig’s range of patented Electric Water Pumps include the EBP (12v), EWP®80 (12v) and the EWP®115 (12v & 24v) in both Nylon66 and Alloy housings. The new EWP®115 (115 litres per minute) in Alloy and Nylon66 is designed to replace a vehicle’s existing mechanical belt-driven water pump and is the latest in Davies Craig’s range of simple, DIY electric water pumps which are all
universal fit. Its lightweight, compact, more powerful design is suitable for all types of vehicles including small, to large plus high-performance and 4WD vehicles. It’s a vital performance product that improves engine cooling management whilst giving more power, torque and increased fuel economy. All deliver 3% to 5% improved fuel economy, increased power while lowering environmental impact by reducing emissions.
The EWP® is available in 2 sizes:
The EWP
® can be used to replace the existing mechanical water pump or as a ‘booster’ to your existing mechanical pump. EWP
® fit most makes and models of vehicles on the road today and by removing the parasitic power losses of belt-driven water pumps, the EWP
® may provide up to
10kW of extra power.
The many benefits of the EWP include:
- Increased Power and Torque
- Increased cooling capability
- Eliminating Heat Soak
- Better control of engine temperature
- Flexible options for pump control
- Options for pump control
1. Used in conjunction with Digital EWP® Controller
The Digital Controller has a micro-processer which will run the EWP® at exactly the right flow rate maintaining the engine temperature you ‘set’.
2. Use in conjunction with Thermal Switch
Combine the EWP® with an adjustable Thermal Switch to add a cooling boost to an overheating mechanical pump cooling system.
3. Continuous Running
Wire the pump to the ignition for maximum cooling - suitable for race vehicles, very hot climates and chronically overheating engines.
EWP Kits come with everything you need for DIY installation including easy to understand instructions.
Digital Controller and Thermal switches are sold separately.

Electric Booster Pump (EBP)
Part Number: 9001 & 9002 (INSTRUCTION SHEETS)
The EBP is a ‘brushless’ 12 volt, high flow, magnetically driven water pump. The EBP motor has no brushes to ever wear out and the pump is magnetically driven by the motor, which means that no shaft sealing is required. There is only one moving part, the impeller, and it is floating in the coolant. The pump chamber is hermetically sealed for trouble free operation. The EBP’s ease of installation, low current draw, high flow capacity and long life makes it ideal for a range of applications.
The many EBP applications include:
- Booster for car heater and LPG systems
- Air to Water Intercoolers for Turbo cars
- Solar pump applications
- Water cooled motorcycle, Go-Kart engines
- Turbo Air/Water Intercoolers
- Household irrigation
- 4WD Caravan applications
The EBP is sold in two forms:
1. Kit (part 9001) comes with everything you need for easy installation including, hoses, clamps, wiring & easy to understand, Do-It-Yourself instructions.
2. Short (part 9002) comes with pump and wiring only.
