Electric water pump

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.

• 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
