Cartridge Mechanical Seal: PZ47D

Features

  • Incorporates an elastomer O-ring as the secondary sealing member.
  • Primary ring and mating ring reverse balance designs allow for ID or OD pressurization, which permits the dual seal to operate as a low-pressure barrier tandem seal or a high-pressure barrier double seal.
  • OD pressurization of the outboard seal avoids subjecting components to high tensile stresses and achieves improved cooling. On vertical installations, it allows venting of entrapped air.
  • Reversible seal head.
  • Non-clogging wave spring outside the product; fits ANSI and ISO seal chambers.
  • Optimized primary ring design for greater reliability.
  • Set screwless outboard seal drive.
  • Tangential inlet and outlet pipe connections below 3.000"/75mm.
  • Type PZ47DP comes standard with a pumping ring.
