Mechanical seals prevent leaks of the pumped fluid and the loss of expensive pumped products. They keep or seal the pump so that the fluid stays inside it 

Our mechanical seal solutions for numerous applications in the chemical, pulp and paper, mining, and power generation industries.

Mechanical Seals in Centrifugal Pumps

Seal Life

• Since the seal must function as a slider or friction bearing, the seal has an unpredictable life span.
• The seal of a centrifugal pump is usually replaced many times during the life of a pump.
• All bearings need lubricant and the seal lubricant is the liquid being pumped. Liquid infiltrates between the contact faces of the primary and mating rings.
• Some of this liquid does find its way through to the atmosphere but is so slight as to only be noticed as corrosion of 'build up' on the pump adapter.
• The condition of the pumped liquid will greatly affect seal life

Types of Mechanical Seals

There are three different types of mechanical seals which are commonly used in the process:

• Cartridge
• Component
• Air

Types of Mechanical Seals for Centrifugal Pumps

• Balanced seals
• Unbalanced seals
• Pusher seals
• Non-pusher seals
• Conventional seals
• Cartridge seals
