Internal cooling flow from discharge to discharge
In the magnetic coupling, eddy currents are generated which lead to heat and cause temperature rise of the containment shell. To dissipate this heat and to cool the sleeve bearings, the Magnetic Coupled Process Pumps use internal cooling flow with pumped liquid as standard.
The cooling flow is led from the discharge side behind the impeller into the chamber between the slide bearings and through the pump shaft via the rotor back vanes again to the discharge side. This design pressurizes the slide bearings and the containment shell with nearly the full discharge pressure and the product remains stable in this area.
The internal cooling flow works without auxiliary piping, no additional thread or flange connections are available. External circulation from discharge flange through magnet end or external flushing will be available as an option.
Balancing thrust loads
Thrust loads of the closed impellers are balanced by wear rings, impeller balance holes and the rotor back vanes. The pump shaft, connected to the impeller is floating. During operation no thrust loads are available, no thrust bearings are required. Start-up rings keep the shaft unit in position at start-up and at shut-down.
Wear rings of the Magnetic Coupled Process Pump
Renewable wear rings are furnished on both the casing and the impeller. Front and back wear rings are part of the axial balancing system.
Mating wear surface materials have a difference in Brinell hardness of at least 50 HB.
Monitoring
Thread connection for containment shell surface temperature probe is standard. Bearing brackets have threaded M8 connections for permanently mounting vibration transducers.
Drain connection, venting
The complete Magnetic Coupled Process Pump can be drained by the drain connection at the bottom of the volute casing. There is no separate drain connection in the magnet end. The process pumps are self-venting. No air or gas will remain in the magnet end when filling suction and discharge pipe. Exception is taken for Magnetic Coupled Process Pumps.
