BV-TNG Elastic mechanical seal
DIN 24960
Analog:
Sterling GNZ, Burgmann HJ92N / HJ97N
Friction couple materials:
Carbographite (Рђ, Р’)
tungsten carbide (РёР·)
silicon carbide (Qi, Q2)
ceramics Al203 (V)
Secondary seals:
fluorine rubber, FKM (V)
nitrile rubber (Р )
ethylene-propylene rubber, EPDM (Р•)
EFKM, FFKM(for example KalrezВ®)
fluorine rubber in PTFE shell, FEP
Parameters:
СЂ = 40 bars
t = -50 ... 220°С
v = 20m/s
Designed with a central protected spring
The location of the spring prevents any contact with the fluid being pumped
Ideal for viscous media, liquids containing abrasive particles and so on,
If it is to be used in sterile processes, it is supplied with electropolished surfaces and profiled elastomer rings to prevent cavity formation
Hydraulically relieved
Does not depend on the direction of shaft rotation
Dimensions as per DIN 24960 (EN12756)
