Features

If a STD is employed, it is possible to change seals with the vessel loaded and under pressure (shaft must be stationary!). Installation dimensions according to DIN 28138 Part 1 are possible. Material properties have to be taken into account.

Advantages

Can be installed in each position.

Operating range

Shaft diameter:
d3 = 40 ... 200 mm (1.57" ... 7.87")
Pressure: p1 = 16 bar (232 PSI)
Temperature: t = +100 °C (+212 °F)

Elastomer sealing element (Item no. 1) with pneumatic or hydraulic actuation
(closing pressure p4 > p1).

! It should be noted that the extremal values of each operating parameter cannot be applied at the same time because of their interaction.

Standards and approvals

  • Compliant to TA Luft (German Clean Air Act)*
(*) Shut-down seals are not specifically mentioned in the TA Luft but may be a solution in certain applications. Their use must be verirfied with the approval authorities.
