Pierburg CWA400 electric water pump incl. plug set

Pierburg CWA400 electric water pump for use in motorsport vehicles or vehicles with very high thermal loads. An electric water pump enables constant cooling regardless of the engine speed. As a result, the vehicle no longer overheats when the vehicle is stationary, where the pumping capacity of the mechanical water pump is at its lowest. In addition, depending on the electrical circuit, after-cooling can be achieved after the engine has been switched off, since the electric water pump can continue to circulate the coolant in the cooling system without engine speed. 

The advantages of a Pierburg electric water pump as an overview:

• Robust and innovative design
• Brushless canned motor
• Integrated variable speed controller
• Controllable via PWM
• Reliable and maintenance free
• High delivery rates

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.
