Davies Craig DC-8930 EWP115 Nylon Electric Water Pump and LCD EWP/Fan Digital Controller Combo Kit 12V

The Davies Craig DC-8930 is a complete combo kit pairing the EWP115 Nylon Electric Water Pump with the LCD EWP/Fan Digital Controller — giving you total command over your engine's cooling system. Designed as a direct complement or full replacement for belt-driven mechanical water pumps, this kit delivers improved coolant circulation, reduced parasitic power loss, and enhanced engine protection.

The EWP115 electric water pump delivers a maximum flow rate of 115 litres per minute (30.38 US gal/min) at 13V DC. Built from anti-corrosive, lightweight, heat-resistant glass-filled nylon with a ceramic-faced impeller seal, the pump operates reliably across a wide temperature range of -40°C to 130°C (-40°F to 266°F). The inlet and outlet are sized at 38mm (1.5") and fit hose diameters from 38mm to 44mm using the included rubber sleeve adapters.

The LCD EWP/Fan Digital Controller actively manages both the electric water pump and your Thermatic fan. It varies the pump speed in response to real-time coolant temperature and allows you to dial in a target temperature for either maximum power output or improved fuel efficiency. The fan is triggered automatically when coolant temperature rises 3°C (5.4°F) above the set point, and the controller continues running for three minutes after engine shutdown — eliminating damaging heat soak and extending engine life.

Key Features:

• Max flow rate: 115 L/min (30.38 US gal/min) @ 13V DC
• Operating voltage: 3V DC to 15V DC; maximum current: 10A @ 13V
• Pump housing: Nylon 66, 30% glass-filled — anti-corrosive and heat-resistant
• Ceramic-faced impeller seal for long service life
• Inlet/outlet: 38mm (1.5") — fits 38mm to 44mm hoses with included sleeve adapters
• LCD controller manages both EWP speed and Thermatic fan operation
• Adjustable target temperature: 60°C to 100°C (140°F to 212°F)
• Fan activates automatically 3°C above target temperature
• Post-shutdown run-on of 3 minutes to prevent heat soak
• Operating temperature: -40°C to 130°C (-40°F to 266°F)
• Releases up to 10kW (13hp) by eliminating belt-driven pump drag
• Universal fitment — mounts inline in the bottom radiator hose
• Australian designed and manufactured
