Pierburg CWA 200 Electric Water Pump for BMW N43 Petrol Engines
Replacement CWA Electronic Water Pump for BMW N43 Petrol Engines - CWA200 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 freePLEASE NOTE:
CWA Electronic Water Pumps can also be used / fitted in many different applications other than the direct OE replacement
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
To do control this you will need an independent controller that regulates the power of the pump, we have a link to them below in this listing
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
