Pierburg was the world's first series-production supplier of an electric coolant pump to BMW.
With matched cooling demand and supply a reduced fuel consumption was easily achieved.
Suitable for engine cooling in combustion engine vehicles and cooling of bigger systems in electrical vehicles.

* Pump pressure is not the same as the system pressure.
Those pumps can of course be used in normal automotive cooling systems with system pressures
in the range of 0.8 to 1.2 bar for instance.
The pump pressure or differential pressure expresses the ´resistance´ of which the pump has to work against.
Tip: A mechanical thermostat is responsible for about half of that resistance. (in most cars)
We will gladly provide you with our controller (tinyCWA) to control the pump.
Just write us an email in this matter or take a look at our online store.
There you will also find product bundles and accessories. :-)
