sleeve
Integral
balance line takes
leakage back to
pump suction.
Thrust Load Balance

Low Energy & Speed
Typically 3” Pumps
Sleeve/Ball
Medium Energy & Speed
3” to 6” Pumps
Sleeve/KTB
High Energy & Speed
Many 4” and 6” Pumps dependent on
power
All 8” and 10” Pumps,
All Fluid Coupling Driven Pumps
Accommodates Thrust
in Either Direction
Bearing Is Very Lightly
Loaded During Operation
Due to Flanged Drum
Spring Loaded Bearing
Improves Reliability
During Starting, &
Stopping
Sized to accommodate
resultant axial load when
pump clearances have
increased to 2x as built.
