 UHMW-PE - also available as conductive material
– up to 90 °C liquid temperature
– excellent abrasion resistance
 PVDF
– up to 115 °C liquid temperature
 Wernit®
- armoured mineral cast
– up to 125 °C liquid temperature
– Epoxy resin with silicon carbide
– best abrasion resistance
 PTFE/ PFA - also available as conductive material
– up to 165 °C liquid temperature
– generally resistant against chemicals, bad abrasion resistance

• Internal rinsing
• Quench
• Continuous rinsing
• Rinsing after use
 Double acting mechanical seals
– Double acting MS to DIN 24960 (back-to-back)
– Stationary, double acting MS BURGMANN HRZ13
WERNERT elastomer bellows-typeWERNERT elastomer bellows-type

 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 -

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
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
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.

DIN 24960 ( back-to-back)DIN 24960 ( back-to-back)
 All common manufacturers
 For the following media:
– harmfull
– water polluting
– harmfull to the
environment
– close to boiling point
– tending to crystallisation
 Effective protection against
dry running
 Protected against pressure

 Developed with BURGMANN
- exclusively manufactured
for WERNERT
 Robust “FGD” - design
 Cartridge on product side for
simple mounting
 For medium up to high solid
containing liquids
 The top-solution for critical
applications

  • 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
  • 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
  • 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.
