Slurry Pump Gland Folowers C044

Tobee® 3/2C-AH Slurry Pump Parts Gland Assembly C044 is for preventing leak, the gland assembly is mainly used to compress the packing to ensure the tightness between the packing and the shaft sleeve. And the gland assembly also can be installed on 3x2C-AH, 4x3C-AH, 3x2C-AHR, 4x3C-AHR Slurry pumps.

The gland assembly is primarily used to compress the packing to ensure a tight seal between the packing and the bushing. Gland Assembly has a split Gland Assembly that is typically used in slurry pumps.

Gland packing

The gland packing's application limit is primarily determined by the extent to which heat developing due to friction can be dissipated. For heavy-duty gland packings, leakage water is actually pre-cooled by means of an internally cooled shaft protecting sleeve and a cooling jacket.

The packing materials generally employed are braided cords made from asbestos-free yarn such as Ramie, Aramid, PTFE, graphite fibres or cotton, which are processed on special machines to form endless square braids.

The packings can be adjusted and are suitable for higher pressures and circumferential speeds than lip seals. Different packing variants are used depending on whether the pump is run in suction head or suction lift operation, or whether it handles clean or contaminated fluid.

In the case of positive pressure, the gland packing is equipped with three to five packing rings. These packing rings are pressed together axially via the gland follower. As a result they expand radially which means the pressure on the shaft protecting sleeve is increased. This has an influence on the clearance gap width and the leakage rate at this location.

The radial gap between the shaft protecting sleeve and the packing rings allows fluid to leak to the outside. This leakage is required to reliably dissipate the heat generated by friction from the gap. When tightening the gland bolts it is important to find a satisfactory compromise between an acceptable leakage rate and sufficient packing cooling.
