The EWP is an electric water pump for automotive engines which replaces the mechanical belt driven pump. It has a smart controller that senses the engine temperature and then varies the pump speed, hunting for a target temperature onto which it locks.

Unique Benefits:

  • Better fuel consumption
  • Better acceleration (top rev. range)
  • Smaller radiator
  • Less weight
  • Less emissions (faster warm up)
  • Less engine machining
  • Easier to assemble and align pulleys and belts
  • Smaller coolant volume
  • No need for mechanical water pump and pulley
  • No need for idler pulley or thermostat
  • Longer belt life
  • Less running time of electric fan
  • Easier to service and replace
  • Bigger head to sump temperature difference
  • Faster warm up

Stage of Innovation:
The company has sold 16,000 pumps into the aftermarket as a kit. The first original equipment manufacturer contract has been acheived with Connaught. The EWP was used in a Ferrari Maranello during their win at the Le Mans 24 hour race at and also by the McLaren F1 team at the Grand Prix 2006
