Type T 211-C
TOP FLANGE DESIGN
with centering projection and double flat
shaft end according to EN ISO 5211.
SHAFT BEARING
All nominal diameters have
a multiple, maintenance-free
shaft bearing.
SAFETY SEAL
FUNCTIONAL SURFACES The one-piece, blow-out proof shaft/disc
The functional surfaces of the is coated with PFA including the safety
shaft seal are machined to precise seal. The disc is covered with at least
tolerances. Forcible adaptation is 3mm. All sealing surfaces are machined.
damaging due to the resilience of
PTFE and is avoided in this design.
PTFE LINER
The PTFE liner is isostatically pressed
and at least 3 mm thick. The broad,
chambered sealing strips also serve
as a double-sided flange seal.
BALL PRINCIPLE
The proven seal according to
the ball principle between disc
and PTFE liner ensures reliable DOUBLE SEALS
long-term operation, without Double seals as standard on both shaft ducts. Primary
critical transitions.
seal (= main seal) achieved by prestressing through
maintenance-free set of stainless steel disc springs.
Secondary seal (= EBRO safety seal) is safely achieved
through a matched combination of a PTFE-Chevron
seal and an additional O-ring.
