Types of mechanical seals

How to select a mechanical seal? What is the difference between Seal and mechanical seals? What are the different types of mechanical valves? There are a number of mechanical seal types,.

Mechanical seals provide the sealing reconciliation between.

Pusher type seals use an axially mounted spring on. Balanced and Unbalanced. Seal types: Induction sealing or cap sealing. Bodok seal , a specialized gas sealing washer for medical applications.

Bonded seal, also known as Dowty seal or Dowty washer. Bridgman seal , a piston sealing mechanism that creates a high pressure reservoir from. Both types consist of two identical metal seal rings mounted in two separate housings of wrapped seal faces.

The metal ring is centered in the housing by the elastomeric element. Half of the mechanical face seal is fixed in the housing and the other half rotates with the opposite side. CartridgePusher seal basically is installed with moving secondary seal. Rather than two flat rings, the sealing interface is a polymer material deflected against a hard material.

This material could be a hardene coated or plated metal , ceramic , or carbide face or sleeve. Cost effective and reliable seal used in high volume water systems - swimming pools, shower pumps, central heating and irrigation. Designed to improve seal performance and life where water interferes with seal faces.

The selection of secondary seal type often determines the temperature and chemical capabilities of the seal. The combination of materials used in the rotating and stationary faces define the abrasive resistance, and chemical. Huge Selection of Rubber Sheets!

Some of the major types of seals that can be found in industrial engineering applications include: Hydraulic seals—are use to seal the opening between various components in the hydraulic cylinder. Pneumatic seals —operate in dynamic applications, often at high speeds,. Piston seals —are used in.

The ASP Type mechanical seal was designed to shorten the working length of the Type seal.

It is slightly wider with a shorter working length spring. Available with Carbon, Silicon Carbide or Tunsten Carbide seal faces. For elastomers we offer Viton, Nitrile, EPDM and on special order Aflas.

Seal faces can be lubricated by the process fluid or, with double mechanical seals , by a proper auxiliary fluid (see chapter relevant to configurations). An stable and complete layer of lubrication greatly affects the performance and the life of a mechanical seal. The most common types of seal faces are: Carbon, Ceramic, Ni-resist, 17- Silicon Carbide, Tungsten Carbide, GFPTFE (glass filled PTFE often called Teflon (R)). Another group of seal faces would be those of coated seal faces.

A double mechanical seal consists of two seals arranged in a series. The inboar or “primary seal” keeps the product contained within the pump housing.

The outboar or “secondary seal” prevents the flush liquid from leaking into the atmosphere. Proven To Seal, Support And Increase Reliability.
