Mechanical Seals

Mechanical seals are one of the most effective ways of sealing rotating shafts, consisting of two lapped faces arranged perpendicular to the axis of the rotating shaft. (This gives rise to the alternative name Radial Face Seal, Pump Seals or Packings.)

One face is fixed to the equipment casing or vessel, while the other is fixed to the shaft and so rotates with it. Frictional heat generation and wear is controlled by maintaining a film of lubricant between the seal faces. As such, mechanical seals resemble thrust bearings.

Eastern Seals UK Ltd supply all common industry standard Mechanical Seal types and dimensional standards. We also provide a huge range of equipment specific Mechanical Seal replacements for all major global pump manufacturers. Our seals are totally interchangeable with all other manufacturer’s equivalent seals. They do not require any modification to the existing seals housings and gland plates.

The material quality is vital to the capability, performance and life of a seal. We therefore only specify superior quality seal materials. Our seals are proven to be durable and of high quality.
The benefits include;
 Reduced wear and reduced heat generation.
 Lower energy consumption.
 Reduced maintenance requirement.
 Tighter control of shaft leakage, true reduction of costs.

We have heavily invested in even further developing reaction and sintered SIC and Nickel and Cobalt TC sintering processes, so that we can exceed previous Single Spring Seal norms. This focus on the best quality face materials is standard throughout our mechanical seal range.

Advanced Custom Design
We also supply any standard or special mechanical design principle to fit your specific dimensional, equipment and application needs. These designs eliminate the common faults found in some original industry standard types through improved design, technology and material quality.
