EWP®150 Alloy Combo – Remote Electric Water Pump & Controller (12V)

Upgrade your cooling system with the Davies Craig 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.
