There mainly 3 sealing types for centrifugal pumps, like shearing pump, sand pump , slurry pump, etc…

1) Asbestos packing

2) Arid seal

3) Mechanical seal

Mechanical seal is the greatest and many costive sealing types. It’s reliable with an extended lifetime.

The fundamental meaning of Centrifugal pump Mechanical seal

Mechanical seal is the seal device for rotary machines. Like centrifugal pumps, centrifuges, reactor along with a compressor equipment. Since the transmission shaft goes through within the inside and outdoors from the equipment, so, the presence of a circumferential clearance between your shaft and also the equipment, equipment of medium leakage outwards with the gap, when the equipment within the pressure is gloomier compared to atmospheric pressure, air towards the equipment inside leakage, and for that reason it has to possess a package to avoid leakage from the shaft. Many seal species, because of mechanical seal has the benefits of little bit of leakage and lengthy service existence and so forth, so in present day world, mechanical seal is sealed within the primary shaft from the equipment. Mechanical seal can also be known as the face area seal, within the relevant standards from the condition is understood to be: “by a minimum of a set of finish faces vertical with respect towards the axis of rotation within the fluid pressure and also the elasticity of compensation organizations (or magnetic) device function and coordination of auxiliary closes to help keep integrating carefully relative sliding form to avoid fluid leakage.

Review of concepts on Centrifugal pump Mechanical seal

Mechanical seal is as simple as a set of or number around the vertical axis for finish face relative sliding within the fluid pressure and also the compensation mechanism of elastic (or magnetic) under the act of coupled with keep adhering auxiliary sealing and leakage potential to deal with seal device.

Common mechanical seal structure comprises an immobile ring (static ring) 1, rotating ring (dynamic ring) 2, 3 elastic components, a spring chair 4, fastening screw 5, a rotating ring auxiliary seal ring 6, and also the static ring auxiliary seal ring 8 along with other components, anti rotation pin 7 is bound around the cover 9 to avoid static the rotation from the ring.

Rotating ring and also the stationary ring is frequently may also based on when they have been the axial compensation capacity and it is known as the compensation loop or non compensation ring.
