DEPAC seal type 322 is a tandem – active, stationary design cartridge mounted double mechanical seal with an integrated barrier fluid pumping device. This seal type is double pressure balanced which guarantees lower face pressure, lower face friction and therefore less wear on the face pair. Additionally full pressure rating is possible on pump and barrier fluid side and the seal faces are self-closing in case of pressure reversal. Available product variants type 321 and type 323 for smaller and bigger sealing chamber cross sections round out this seal’s universal application opportunities.
Maximum temperature / pressure / speed indicates operating extremes independently and does not imply the seal will function at these extremes at the same time. Contact Pactor if in doubt.
