What are Mechanical Seals

  • Mechanical Seals help in reducing leaks which leads to significant savings that come from less waste, reduces pump failure and eases maintenance.
  • One major factor in using mechanical seals by Indian companies in recent years is that such use reduces hazards to pump operators and adverse environmental conditions, high rotational speed and pressure levels place demanding requirements on sealing technology employed in the process industry.
  • The seal system’s role in a pump is to minimize leakage of the pumped liquid from the area in the pump where the drive shaft enters or exits the casing.
  • Mechanical seals are employed in harsh conditions such as well drilling, freshwater distribution, lift stations, and wastewater treatment in the water & wastewater industry.
  • The introduction of mechanical seals in cooling towers, hot & cold water, circulation pumps, booster pumps, boiler feed, and fire pumps in the HVAC industry is also expected to drive the Indian mechanical seal market.

Types of Seal

  • The Global Mechanical Seals market is segmented by type, which is further segmented into pusher and non-pusher, conventional seals, balanced and unbalanced seals and cartridge seals. Continuous adoption of advanced sealing material in several industries is expected to grow the cartridge seals segment in the years to come.
  • The cartridge seals segment is estimated to have exponential market opportunities as they are designed as universal shaft seals in the seal chamber of pumps, containers or pipelines.

Seals have been divided into 3 categories for further understanding:

  1. Static & Dynamic Seals

Static Seals

  • Used to seal 2 stationery parts
  • Examples - Gaskets/ O Ring

Dynamic Seals

  • Used to seal 2 rotating or stationary/ rotating parts

  • Examples - Gland packing, Mechanical Seals

  1. Pusher & Non-Pusher Seals

Pusher Seals

  • Movable O ring
  • Used in low-temperature services
  • Light liquid services - ethylene, propane, methane, butane.
  • Single-spring or Multi spring
  • Combination of Rotary face & Stationery face

Non-Pusher Seals

  • Bellows assembly
  • Bellow is a component consisting of spring and stationary-like characteristics
  • It doesn’t have any springs
  • Used in high-temperature applications
  1. Balanced & Unbalanced Seals


  • Same opening & closing face
  • Less heat is generated across the seal face
  • Seal life is more


  • Difference in size of opening and closing face
  • More heat is generated across the seal face
  • Less seal life
