Wet rotor pump, especially for transporting coolant in vehicle engines, has motor with rotor connected to pump wheel via common shaft, cooled by fluid and coated with corrosion inhibitor

摘要

The wet rotor pump has a pump wheel (10) for transporting a fluid and a motor with a rotor (20) connected to the pump wheel via a common shaft (12,14). The motor's rotor is cooled by the fluid and is coated with a corrosion inhibitor. The protective coating (28) seals the motor's rotor against with respect to the fluid.
