1.Internal structure of pump

A pump is a machine that works to move fluids, as in lifting a liquid to its inside. For example, its impeller rotates to move water.

2.Mechanical seal installation location in pump

A mechanical seal is installed on the impeller rotating shaft. This prevents the liquid from leaking through the clearance between the pump body and the shaft as a shaft seals.

3.Mechanical seal installation location on shaft

Mechanical seals are mostly comprised of two rings: a rotary ring on the shaft and a stationary ring on the pump housing.

4.Mechanical seal structure (stationary and rotary rings)

The rotary ring rotates with the shaft. The stationary and rotary rings rub against each other ensuring a clearance in the order of micrometers maintained between them. Where they rub against each other, they are referred to as "face materials".
