How do you describe a mechanical seal?

A mechanical seal is simply a method of containing fluid within a vessel (typically pumps, mixers, etc.) where a rotating shaft passes through a stationary housing or occasionally, where the housing rotates around the shaft.

What is inside mounted seal?

Single seals can be mounted inside the process liquid or outside the process liquid. Inside-mounted seals are sometimes described or even defined as being mounted within the boundaries of the seal chamber. This means that the process fluid is present on the outside diameter of the seal.

What is a Type 1 mechanical seal?

Suitable for a wide range of service conditions ranging from water and steam to chemicals and corrosive materials, the Type 1 mechanical seal is ideal for use in pumps, mixers, blenders, agitators, air compressors, blowers, fans and other rotary shaft equipment.

What is gland in pump?

A gland is a general type of stuffing box, used to seal a rotating or reciprocating shaft against a fluid. The gland at the rotating shaft of a centrifugal pump may be packed in a similar way and graphite grease used to accommodate continuous operation.

What is pusher type mechanical seal?

A pusher-type seal consists of a primary sealing ring assembled with an ‘O’ ring and springs (can be one or multiple). The purpose of this is to force the sealing fluid across the face and keep it from leaking to the ID (atmospheric) side of the seal.

What is quench in mechanical seal?

Quench is the term used for an arrangement that applies an unpressurised external fluid to a mechanical seal’s outboard faces. Lubrication/cooling of the stand-by seal. Exclusion of air: prevents the leakage from reacting with the atmosphere (e. g. crystallisation of the leaking fluid)
