Pierburg CWA Electric Waterpump - CWA 400

This upgrade is great for Track Car and Motorsport applications but can also be used on road applications

Pierburg were one of the first to introduce the electric water pump to line production for BMW in 2004

They and others are now widely available in the aftermarket and got many advantages over conventional mechanical pumps

Some of which are the freedom of installation and the independence of engine revolutions

Also the pumps are very well built and with its brushless canned motor they are practical maintenance free (plus it looks like a turbo!!)

Specifications:

Supply voltage: 8-16 Volt
Current consumption: max. 36A in operation and 0,2mA in standby mode
Differential pressure: 0.85 bar
Flow rate: 150l/min @ 0.85bar / 220l/min @ 0.55bar


Advantages of electric water pumps:

The best benefit for aftermarket and motorsport application would be the freedom of installation and use

You can mount the pump practically anywhere (yes even in the trunk) and it is completely independent of the engines revolutions

Most of the cooling power is needed when the car is idling around in a complete standstill
Sadly that’s the situation where a mechanical water pump got its least amount of power
So most of the time a conventional pump is oversupplying the engine with coolant flow

The Electric Water Pumps however can deliver the right amount of flow at any time it is needed


When installing these water pumps the conventional mechanical pump will need blanking and replacing with an idle pulley. Addition coolant hoses / pipes will be needed depending on where you decide to mount the new pump

To do control this you will need an independent controller that regulates the power of the pump. These are listed here
