Secondary containment of the Heavy Duty Pump
If desired, a mechanical stand-by seal can be supplied in lieu of the inboard labyrinth seal. This mechanical seal separates the magnet area from the oil bath respectively the atmosphere and forms, together with the closed bearing bracket lantern, a secondary containment behind the containment shell.
In case of leaking containment shell, the pressure inside the bearing bracket will increase and activate the seal. Leakage will be collected at the bottom of the bearing bracket and can be monitored by level detection device.
Double sleeve bearings of the Heavy Duty Pump
The pump shaft is carried by two sleeve bearings. These bearings are located in the pumped liquid. Bearing material is pure alpha grade Silicon Carbide. SiC is corrosion proof to all kinds of acids and hydroxides and suitable for all common pumped liquids. Extreme hardness and wear resistance accept also abrasive solids.
An additional "diamond like Carbon coating" reduces friction losses and accepts dry running conditions until monitoring device will switch off the unit. The SiC-bearing parts are shrink-fitted in metallic holders or elastically beared by metallic tolerance rings. This protects the bearing unit against shock or thermal stress, caused by different thermal expansion of metal und ceramic. Design temperature is 400°C. Both stationary sleeve bearings are located in the common bearing housing which guarantees absolute centricity.
Antifriction bearings of the Heavy Duty Pump
The outer magnet shaft is fitted with generously dimensioned antifriction bearings. The bearings are L10 rated for an average life in excess of 3 years. The oil bath is protected against the atmosphere by a replaceable labyrinth seal. Oil level is controlled by a constant level oiler and additionally by a bull's eye sight glass. Oil mist lubrication available as an option.
