Coolant Pumps
Over a decade ago, we were the world’s first supplier to commence full-scale production of an electrical coolant pump for main engine cooling – and we haven’t stopped innovating since. Our extensive portfolio offers solutions ranging from the cooling of auxiliary circuits to main cooling of internal combustion engines, batteries, e-motors, and fuel cell stacks. Stationary battery systems, fast charging stations, data centers, and 5G network towers all require thermal management.
Our products make it easy to attain even the most ambitious targets. It doesn’t matter if you use a traditional water-glycol mixture or advanced dielectric fluid, or if you use a low- or high-voltage network – we have the right pump for you!
Our mechanical pump portfolio consists of conventional direct drive pumps that offer a reliable and compact package as well as fully variable pumps, controlled by a solenoid valve for the ultimate combination of reliability and efficiency. All our products are suitable for passenger car and commercial vehicle applications.
