Shaft seal maintenance
Mechanical-seal maintenance
CAUTION:
Running a mechanical seal dry, even for a few seconds, can cause seal failure and physical
injury. Never operate the pump without liquid supplied to the mechanical seal.
Cartridge-type mechanical seals
Cartridge-type mechanical seals are commonly used. Cartridge seals are preset by the seal
manufacturer and require no field settings. Cartridge seals installed by the user require
disengagement of the holding clips prior to operation, allowing the seal to slide into place. If the
seal has been installed in the pump by ITT, these clips have already been disengaged.
Reference drawing
The manufacturer supplies a reference drawing with the data package. Keep this drawing for
future use when you perform maintenance and seal adjustments. The seal drawing specifies
the required flush fluid and attachment points.
Before you start the pump
Check the seal and all flush piping.
Mechanical seal life
The life of a mechanical seal depends on the cleanliness of the pumped fluid. Due to the
diversity of operating conditions, it is not possible to give definite indications as to the life of a
mechanical seal.
