Reduced inventory

From an operational point of view the stuffing box is different as it requires some leakage to ensure lubrication and to prevent heat build up. The mechanical seal box should be leak free.

A quench plan, as the name indicates, is designed to quench or cool the seal. It is normally used if short periods of dry running are expected. As illustrated bellow, the fluid is introduced into the area between the back of the seal faces and the close fit exit on the drive side of the pump.

Definition of dredge and slurry pumps

A slurry is any mixture of a fluid (such as water) and a powdery solid. Slurries are used as a convenient way to handle bulk solids in the mining, steel processing, foundry, power generation and, more recently, frac sand mining industries. Slurries typically behave like viscous viscous fluids, flowing under gravity, but can also be pumped as needed.

Slurry pumps with rubber lining are the ideal pump for the mineral sand industry. They have a special rubber lining that makes them heavy duty pumps capable of withstanding high levels of abrasion.
