Pierburg CWA400

The CWA400 is the next development stage of the very successful principle the CWA200 used.
(A brushless and fully canned motor for instance)
This pump is supplying more than double the hydraulic performance at nearly the same dimensions.
Suitable mainly for engine cooling in combustion engine vehicles.

Know-how:

* 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)

 

Controller:

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 here at our online store. :-)
