Heat exchanger design specific features

  • Simple and compact design
  • For plain shafts
  • Seal balance (353,313) reduces the impact of fluid increased pressure
  • Multiple coil-springs (153, 353) provide uniform load on seal faces interface
  • Single spring (313) provides better corrosion resistance of unit

What one needs to know when choosing a mechanical seal?

Equipment characteristics

Shaft diameter, temperature, pressure and fluid type are the main parameters when choosing a seal, but there are many other factors

Choice of a manufacturer is important

Lots of products that do not meet the required quality are being produced at the market now.

Service life extension

Operating time of component part is several times longer if the mechanical seal is selected correctly
