Dual Mechanical Seal WM560D

Mechanical seals are devices that seal machines between rotating parts (shafts) and stationary parts (pump housing) and are an integral part of the pump. Their main job is to prevent the pumped product from leaking into the environment and are manufactured as single or double mechanical seals. Dual Mechanical Seal WM560D configuration consists of two independent seals mounted within a sealed chamber outside the pump, which is flushed with an independent water supply at a flowrate of approximately two to four gallons per hour (minimum) and pressure slightly higher than the maximum expected operating pressure of the pumped solution. This water may be recirculated for conservation purposes provided cooling of the same is accomplished when necessary.

How Dual Mechanical Seal WM560D Works

A double mechanical seal has two primary seals with a barrier or buffer fluid area in between. Each primary seal typically consists of a softer, narrower stationary face accompanied by a harder, wider rotating face. This arrangement enables the softer seal to wear while maintaining the integrity of the harder faced seal during service.

The Application of Dual Mechanical Seal WM560D

● To prevent a costly product from leaking.

● To prevent a dangerous product from leaking to the atmosphere.

● To prevent a pollutant from escaping to the atmosphere.

● As a backup seal to prevent costly downtime when the first seal wears out or fails. This is an important element in any predictive maintenance program.
