DAVIES CRAIG electric water pump EWP150 + digital controller, 12V, 8970

Description

The Davies Craig EWP150 Alloy Electric Water Pump (12V) is a high-flow pump that mounts remotely, away from the engine. It is built for performance vehicles that need tight control of engine temperature.

It has an open flow rate of 162 litres per minute (42.8 g/min) and is designed for high-horsepower, turbocharged, supercharged and modified engines. The EWP150 handles excess heat well and can also be used in intercooler systems.

A mechanical pump is driven by the engine, while the EWP150 is not. This takes load off the engine, which frees up power and improves overall efficiency.

The EWP Combo is meant for a full conversion to an electric water pump. You can remove or disengage the belt-driven mechanical water pump. In most applications you can also remove the factory mechanical thermostat, so the cooling system is fully controlled.

Converting to an EWP Combo system gives you optimal temperature management, better efficiency and complete control over how your engine is cooled.

The LCD EWP/Fan Digital Controller is included in this Combo pack and runs both the EWP and the Thermatic fan. It changes the speed of the EWP according to the engine's coolant temperature. You can choose between several temperature settings for either maximum power or fuel efficiency.

Controller features

• Black and white numerical screen
• Celsius or Fahrenheit display option
• Set / targeted temperature memory
• Override feature to assist bleeding the EWP

Controller warning alarms

• Plus 10°C (14°F) above the set/target temperature
• Under temperature: 40°C after 5 mins
• Temp sensor error / over or under voltage / EWP error

Key benefits

• Universal fit
• More power
• More cooling
• Increased fuel efficiency
• Longer engine life
• World-leading technology

Installation

In most cases the radiator hose gives the EWP enough support. Where the pump does need mounting, it must be soft mounted to protect it against vibration. For the EWP115, EWP140 and EWP150, the DC8700 or DC8710 mounting bracket is recommended.
