How do you read a mechanical seal size?

How do you read a mechanical seal size?

On the back side of the “seal head” (the end which fits towards the “spring”), measure the inside diameter. This will determine the seal size diameter – which is either the shaft size or the sleeve size that the seal fits over. The front side of the seal usually has a black carbon face.

What material is used in the mechanical seal?

For mechanical seals, these include silicon carbide, tungsten carbide, and alumina oxide. Other materials such as silicon nitride are used in specialty applications. Not all ceramics are the same. Characteristics such as thermal conductivity and thermal shock resistance vary significantly depending upon the material.

What type of material is the secondary seal made of?

Typically one of the seal faces is manufactured out of a Carbon Graphite type material and the counter-face out of a harder Ceramic or Carbide material. Seal hardware, springs and drive mechanisms tend to be produced out of metallic materials and the secondary seals are elastomeric or polymeric type materials.

How do you identify a mechanical seal?

To determine the size of a component mechanical seal, measure the inside diameter of the seal face, the length of the spring, and diameter and thickness of the stationary seat.

What are the different materials used in making packings seals and gaskets?

Viton, Neoprene, Nitrile, Pure Gum Rubber, EPDM Butyl, and SBR are just a sampling of the most common rubber or elastomeric materials commonly used to manufacture gaskets.

What does SC mean on oil seal?

Rotary seals / Standard shaft seals The SC profile is a shaft seal composed of a single metal cage with a rubber coating and a primary sealing lip with integrated spring.

Which are the three basic types of mechanical seals used in pumps?

What are the main types of pump shaft seals?

  • Packing. Packing (also known as shaft packing or gland packing) consists of a soft material, which is often braided or formed into rings.
  • Lip seals.
  • Double seals.
  • Tandem seals.
  • Cartridge seals.
  • Gas barrier seals.
