Mechanical Seals

De.mem Pumps / Graco Stand: D142

A mechanical seal is a very effective device. Every centrifugal pump must accommodate a spinning shaft while mechanically maintaining fluid or gas contained in the “wet end” of the pump. Mechanical seals consists primarily of a rotary seal face with a driving mechanism which rotates at the same speed as the pump shaft, a stationary seal face which mates with the rotary and is retained using a gland or in some pump models an integral stuffing box cover, a tension assembly (utillizing springs or a metal bellows) keeps the rotary face firmly positioned against the stationary face preventing, excluding, and containing contamination and leakage, both when the pump is not in operation and when the pump shaft is rotating. 

Custom-engineered solutions can help lower total cost of ownership by working with rather than against the application’s environment. Products that have been custom engineered for the precise equipment and exact environment they will be operating within.
