Coolant pump

Coolant pumps are often part of liquid cooling and ensure the forced throughput of the coolant in technical systems with high levels of waste heat, such as engines , brakes , cooling units , computers , nuclear reactors and many others.

All commercially available pumps are used as the coolant pump. Depending on the design of the cooling system, the pump circulates the coolant in a coolant circuit or draws in fresh water, which is separated out after heat absorption and no longer passes through the system. Deionized water treated with additives is mostly used in coolant circuits . Thus rot , corrosion and deposits can be counteracted or avoided.
