What do you need to know about mechanical seals?
This article will explain what a mechanical seal is and the key design features that make them work. 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 are the sealing points on a mechanical pump?
A basic mechanical seal contains three sealing points. The stationary part of the seal is fitted to the pump housing with a static seal –this may be sealed with an o-ring or gasket clamped between the stationary part and the pump housing.
What are the parts of a seastar seal kit?

What are the features of a double pressurized seal?
The more common multiple seal configuration is called a Double (dual pressurized) seal, where the two seal face sets are oriented in opposite directions. The features of this seal arrangement are: Potentially five times the life of a single seal in severe environments.

What is the purpose of a diaphragm seal?
A diaphragm seal is a flexible membrane that seals and isolates an enclosure. The flexible nature of this seal allows pressure effects to cross the barrier but not the material being contained.
How big is the gap between the faces of a mechanical seal?
This is achieved by maintaining a precise gap between the faces that is large enough to allow in a small amounts of clean lubricating liquid but small enough to prevent contaminants from entering the gap between the seal faces. The gap between the faces on a typical seal is as little as 1 micron – 75 times narrower than a human hair.
