Impeller pump WUP series

waterwith brushless DC motorfor automotive applications

The electronically commutated water circulation pump (WUP) with its brushless DC motor is a dependable alternative to conventional motor vehicle pumps with their wear-prone mechanical commutation systems. The pumps are chiefly used wherever additional cooling or heating functions need to be performed. Turbo charging, power electronics and EGR coolingduties are just some of the examples which also include auxiliary heating, residual heat extraction and vehicle interior heating systems. The WUP is engineered in such a way that the pump itself and its electric drive are hermetically sealed from each other. Dispensing with any complex coupling mechanisms to ensure leak-proof sealing of the drive components has the advantage of substantial weight savings. The pump is regulated electronically and with all usual engine coolants. Thanks to the low number of moving parts, the pump operates very smoothly and hence quietly. Additionally, the electronically commutated design results in an exceptionally compact build.
