Cleaning Solution Leakage
- Worn Bearings & Seals
Water exiting from the CIP holes in the Tee Housing will cause a slight spray to exit around the Tee and Nozzle Housing.
However, excessive leakage from the Tee Housing or Nozzle Housing usually indicates worn Housing Bearings (29), and Seals
(31). Inspect them for wear (sealing lips are worn to a smooth surface) or damaged lips or loss of spring tension (indicated by
excessive dry deposits of dirty or abrasive cleaning solution on the spring), and replace as required.
- Worn Bearing Cups
Inspect the Bearing Cups (30) for excessive wear (grooved or scored), particularly near the inside flange where they contact the
(31) Seals. Replace any that show distinct grooves.
- Worn Static Seal Contact Surfaces
Inspect the Bearing and Seal contact surfaces of the Stem (3) and the nose of the Tee Housing (4). If these are worn or
grooved, new Bearings and Seals will be ineffective. Replace the damaged parts as required.
- Leak On Either Side of Bearing Housing
Verify that the Stem Cap SHCS (41) are tight. If tight, inspect the Stem Collar (2), Rotor Shaft Upper Bearing Housing (26), and
Stem (3) for nicks or burrs. File, if necessary.
- Worn Stem Collar O-Rings
Severe leakage between the Inlet Collar (1) and Stem Collar (2) may indicate worn or damaged Stem Collar O-rings (56) and
(57). Remove the Stem Collar as described in Section 2, and inspect the O-rings for signs of damage or wear.
