Shaft SleevesLong Life Pump Shaft Sleeves

Pump shaft sleeves form one of the main production lines for our PTA systems. These sleeves have been produced in the past from hardened steels and various sprayed metal coatings. The advantages of sleeves produced using the PTA processes are as follows:

  • Pump sleeves have lasted more than 10 times the life of conventional sleeves.
  • The increased life now exceeds the life of wet end components (pump volutes, doors and throat bushes) reducing pump maintenance costs and maintenance frequency.
  • Lower environmental impact is achieved through reduced gland leakage and a reduced requirement for gland water.
  • High temperature operation resulting from gland water failure or “dry” operation has not caused sleeve failure.
  • Installation and maintenance of sleeves and packing is a simple process (when compared to mechanical seals).
  • The cost is a fraction of that of mechanical seals.
