Davies Craig Brushless EWP180 Combo - Remote Electric Water Pump (12V) - DC8945

Brushless EWP®180 Combo - Remote Electric Water Pump (12V)(#8945) 12 Volt | Part Number: #8945 The Davies Craig Brushless EWP180 Combo – Remote Electric Water Pump (12V) combines the high-performance Brushless EWP180 Remote Electric Water Pump with the Brushless Variable Speed Fan & EWP Controller to deliver a complete intelligent engine cooling solution. Designed to automatically vary coolant flow based on engine temperature, the system provides precise thermal management, faster engine warm-up, improved cooling efficiency and reduced parasitic engine losses. At the heart of the system is the Brushless EWP180, engineered for applications where flow under pressure truly matters. While many electric water pumps promote peak open-flow figures, the EWP180 delivers an impressive 93 L/min at 1.5 Bar (15m Head)—the specification that reflects real-world cooling performance through radiators, intercoolers, heat exchangers and long coolant circuits. Combined with the Variable Speed Controller, the pump speed is continuously adjusted to maintain a stable engine temperature while also providing intelligent control of compatible Davies Craig Brushless Thermatic® Electric Fans. Ideal for high-performance street vehicles, motorsport, 4WDs, marine applications and water-to-air intercooler systems, the Brushless EWP180 Combo provides exceptional cooling performance, improved engine efficiency and long-term reliability. The magnetic drive brushless motor eliminates carbon brush wear, while the controller's programmable operation ensures coolant flow is matched precisely to engine demand.

Traditional mechanical water pumps operate at engine speed regardless of cooling demand, consuming engine power and often circulating more coolant than necessary. The Davies Craig Brushless EWP180 Combo intelligently controls coolant flow based on engine temperature, providing maximum cooling only when required. The result is faster engine warm-up, improved thermal efficiency, stable operating temperatures and reduced engine load. Combined with intelligent variable-speed electric fan control, the system delivers complete cooling management for high-performance engines, motorsport applications and demanding cooling systems where precision, reliability and maximum flow under pressure are critical. Advanced Brushless Motor Technology Unlike conventional brushed electric water pumps, the EWP®180 uses a magnetic drive brushless motor, delivering: Longer service life Reduced electrical noise Greater efficiency Improved reliability in continuous duty intercooler circuits Stable flow in high-temperature engine bays Full PWM control (100–1000 Hz) allows integration with modern ECUs and standalone controllers, enabling intelligent temperature-based flow management for both engine cooling and intercooler systems. For optimum coolant management, Davies, Craig recommends the installation of Brushless Variable Speed Fan and EWP® Controller (Part #0550 or #0551). Davies, Craig has a full range of Digital Thermatic® Fan Switches for when on/off control of the EWP® is desired (Part #0444, #0445, #0448, #0435, #0438 & #0500). The Brushless EWP® can also be controlled using an aftermarket ECU Designed for Intercooler & Charge Cooling Systems For performance builds running water-to-air intercoolers, coolant flow stability is critical to reducing intake air temperatures and preventing heat soak. As a dedicated intercooler pump / charge cooler pump, the EWP®180: Maintains high circulation through restrictive intercooler cores Supports large front-mounted heat exchangers Delivers consistent flow during sustained boost Reduces temperature spikes between pulls Improves thermal recovery during track sessions With 93 L/min at 1.5 bar, the EEWP®180 significantly outperforms typical small OEM-style intercooler pumps in high-demand applications. High Performance Cooling & Intercooler Flow Open Flow Rate: 180 L/min (47.6 GPM) Rated Flow: 93 L/min @ 1.5 bar (15m head) Maximum Head Height: 18.4 m (60ft 4.4") Maximum Power: 450 W Rated Current: 33 A (Max 39 A) Whether you're running a high-boost turbo engine, LS conversion, endurance race car, off-road vehicle, marine setup, or a high-capacity water-to-air intercooler system, the EWP®180 provides the flow and pressure capability required to maintain stable coolant and intake air temperatures under load. For performance builds using charge coolers, this pump ensures rapid coolant circulation between the intercooler core and heat exchanger — helping reduce heat soak and maintain consistent intake air temperatures during repeated pulls, track sessions or sustained boost conditions. Built for Extreme Conditions Operating Voltage Range: 13.5V – 19V Ambient Temperature: -40°C to 80°C Fluid Temperature: -40°C to 120°C IP68 Rated – Fully sealed against dust and water ingress EMC Compliant From extreme cold starts to high ambient under-bonnet temperatures and boosted engine environments, the EWP®180 is engineered to perform. Heavy Duty Construction Manufactured using high-grade materials including: ADC12 Aluminium housing Stainless steel components Silicon carbide mechanical seal Nitrile sealing elements PPS composite internals Designed specifically for water and water-based coolant systems, including dedicated intercooler circuits, the EWP®180 ensures durability and corrosion resistance in demanding cooling environments.

Ideal Applications High performance street cars Turbocharged & supercharged engines Water-to-air intercooler systems Charge cooler setups Circuit & endurance racing Drag racing 4WD & off-road vehicles Marine cooling systems Custom engine conversions 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 EWPÒ 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® Block 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.
