Subject: Understanding Mechanical Seals For Pump And Their Types.

By John Gan


Subject: Mechanical Seal is mainly a device that's used to control and stop the leakage of liquid or gases from the pump.

There are a lot of types of pump seals with totally different configurations that can assist the user to identify the perfect seal as per their application and their usage. These mechanical seals for pumps can be found in several designs and mechanism, among them some are: Cartridge Balanced Unbalanced Pusher Non-Pusher Conventional

The cartridge seal is the strongly beneficial seal by the pump users. The cartridge mechanical seals are positioned immediately on shaft which assists remove the seal setting and measurement requirements on set up, and provide low upkeep cost in addition to limits the seal errors.

The balanced and unbalanced seals are principally designed to manage the pressure within themechanical seal pump.

Stationary Components:It is fixed with the pump seal, it's sometimes made of stainless-steel or some are made from ceramic or any type of harden material. Its axial surface is polished. On the center of the stationary pump a rubber (o-ring) is put on seal to stop leakage. This can be obtained from a pump seal supplier.

The non-pusher seal does not have secondary seal shifting with the shaft just like the pusher seal. In non-pusher seal the secondary seal is static often, even throughout the pump operation.

The leakage is especially prevented as a result of the o-ring parts are compressed between the stationary components. The leakage by the shaft cannot happen as well, because the o-ring is positioned within the rotary component which grips in opposition to the shaft.

  1. So to get some accurate values, digital scales were introduced and it has some facilities which analog doesn't have. Different types of weighing scales are there such as bench scales, portable scales, fork scales, floor scales and more; each type are used for some specific purpose. yük hücresi
