SEAL SLEEVEĀ S027

This term is used to describe the inner barrel of a balanced rotating seal, the sleeve used to contain the cartridge seal components, or the sleeve put on the pump shaft to protect the solid shaft against corrosion or fretting damage from the mechanical seal.

The following illustration shows the inner barrel or sleeve of a balanced, rotating mechanical seal attached to the shaft by setscrews and sealed to the shaft by an O-ring.

 

Double ended pumps use two sleeves to position the impeller between them.
