WERNERT elastomer bellows-type WERNERT elastomer bellows-type mechanical sealmechanical seal

Well proven for decades, also with solid laden liquids

Bellows acts as spring and auxiliary seal

Bellows materials:

– CSM up to 80°C

– FPM up to 100°C Seal rings of Carbon, SSiC or

Al2O3 Up to 3 bar(g) inlet pressure Shown is internal rinsing -

Quench, continuous rinsing or rinsing after use as an option

Rotating seal ring Stationary seal ring bellows

WERNERT PTFE bellows-type WERNERT PTFE bellows-type mechanical sealmechanical seal

Generally resistant against chemicals

PTFE- bellows with spring Up to 115 °C and up to

3 bar(g) inlet pressure Seal rings of Carbon, SSiC,

Al2O3 or PTFE/glass Shown is internal rinsing -

Quench, continuous rinsing or rinsing after use as an option

18.04.23 14

QuenchQuench

Pressureless liquid rinsing on atmospheric side

Usually: clean water or demineralised water

Flushing rate 30 l/h, quenching liquid does not contaminate the product

Open or closed circuit Used for

– crystallizing media

– conglutinating media

– protection against certain types of dry running caused by blocked suction pipe work

18.04.23 15

Continuous rinsingContinuous rinsing

Pressurized rinsing of the mechanical seal

Usually: clean water Flushing rate 40 - 250 l/h,

verges into the product Used for

– heavy solid laden liquids

– liquids closed to the boiling point

– undissolved gases in the liquid

– certain types of dry running caused by air in the pump

18.04.23 16

Rinsing after useRinsing after use

Pressure less rinsing of the sealing chamber during and after shut-down

Usually: clean water Flushing rate 40 l during 5

minutes Used to prevent

– sedimentation

– crystallizing

– conglutinating Is not replacing the flushing

of the whole pump, but completing it.
