During normal operation heat is generated inside the magnetic coupling due to hydraulic friction and eddy currents in the wall of the separation can by the moving magnetic fields. Cooling of the cou- pling see chapter 3.16.3 Circulation pump.

Maximum allowable temperature and nominal torque

Samarium Cobalt (SmCo): 280°C

Neodymium Iron Boron (NdFeB): 120 °C

The type of the magnetic coupling is related to the selected pump type. There are three types of magnetic couplings with different nominal diameters to cover the five pump sizes. Each coupling type is available with magnets in different lengths and in both magnetic materials. (see table

below).

3.16.2 Rotor bearing assembly

The rotor bearings are designed to support the radial and axial load generated by the rotor and

are lubricated by the pumped liquid. The bearing assembly is supplied as a complete set, consisting of two radial bearing bushes mounted in the bearing holder, two separate axial bearing faces and a shaft sleeve. The shaft sleeve is clamped between the two axial bearings via a shaft nut and is rotating with the shaft. The front faces of the radial bearing bushes are acting as axial bearing faces. The axial bearing clearance is determined by the length of the shaft sleeve, so there is no adjustment required. That means in case of wear or damage the complete bearing assembly must be exchanged.
