Fig 4.3-6  Typical Slurry Mechanical Seal 

For information on mechanical seals, consult the 
manufacturer’s manual. 

4.3.4 Bearings 

The bearing assembly is a cartridge design mounted on a 
concentric pedestal with an adjustment mechanism for 
setting the impeller axial clearance. 
Standard lubrication is grease.  Oil lube is also available.  
For lubrication quality and quantity, see Section 7.2. 

Basic bearing parts are listed for reference. Note that the suffix can 
vary depending on configuration and vendor. Replacement bearings 
are available from GIW/KSB

.

1) Timken Co. part numbers shown, Koyo is also an approved 
supplier.
2) 125 mm taper roller bearing assembled from two single row 
bearings.  Other sizes are TDO (one piece cup) design.
