3.16.3 Circulation pump

To ensure proper lubrication of the rotor bearings and cooling of the magnetic coupling a circulation pump is providing a controlled flow over the magnetic drive. The liquid is flowing from the discharge side of the pump via holes and grooves in the bearing assembly and the magnetic drive back to the suction side of the pump. This circulation pump is designed as an internal gear pump where the drive gear, integrated in the front axial bearing is driving a disk rotor which is rotating in an insert, situated between rotor and intermediate cover. The insert and the complete rotor bearing assembly are mounted on the intermediate cover.

3.16.4 Sealing rings and gaskets

The magnetic drive replaces a dynamic shaft sealing, so there are only static seals on TopGear MAG pumps. The intermediate cover, separation can and pump cover are sealed with O-rings. Standard O-ring material is FPM, but other O-ring materials can be supplied on request. The maximum allowable operating temperature and chemical resistance must be considered for selection of the O-ring material.

Max. allowable temperature for FPM (Fluorcarbon) = 200 °C

The topcover/safety relief valve is sealed with a graphite gasket and following sealing rings are used to seal plugs:

Cast iron pump casing parts: Stainless steel casing parts:

Steel sealing rings with asbestos-free filling PTFE sealing rings
