In the case of positive pressure, the gland packing is equipped with 3 to five packing rings. These packing rings are pressed collectively axially through the gland follower. As a outcome they expand radially which implies the pressure on the shaft protecting sleeve is elevated. This has an influence on the clearance gap width and the leakage price at this location.

In the late 1930s, most likely about 1938 or 1939, mechanical seals began to replace packing on automobile water pumps. The renowned Jeep of WWII employed a rubber bellows seal in the water pump. Soon after WWII, all automobile water pumps utilized mechanical seals.

NASH solutions mechanical seals for rotating gear such as steel agitators, mixers, filter dryers and vertical cone dryers. A additional essential differentiating feature is that seals can be unbalanced and balanced. In the case of unbalanced mechanical seals, the seal face is exposed to the comprehensive stress to be sealed.

High bearing loads, consequently causing the mechanical loading of the shaft. This could cause the grinding of the impeller in the pump casing or even much more leakage of the mechanical seal. In the case of boiler feed pumps, seals have to cope with high sliding velocities, heat transfer from the fluid handled and the heat generated by friction.
