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
