The Type PO1 & P02 are multi-coil spring unbalanced Pusher Seals catering to almost 90% of general purpose sealing requirements.

First introduced in the early sixties and are now in service around the world. Today's P Seals incorporate all the latest design features based on millions of hours of field service.

Salient features:

  • Wedge or 'O' Rings allow lower spring loads and a cooler running seal, thus shaft fretting is minimized.
  • Narrow cross-section lets the seal slide into the smallest stuffing box.
  • Also ideal for external mounting.
  • This range is available with the carbon locked in by a circlip for ease of assembly on heavy duty and vertical pumps. Designated as P11/PI2 for unbalanced versions with 'O' Ring and wedge respectively.
  • Can be provided as an engineered cartridge construction in single, double or tandem arrangements with a complete range of auxiliary sealing devices and seal support systems.

Because all parts are interchangeable, you can convert from an unbalanced seal to a balanced seal merely by changing the carbon. This means fewer spares to stock and much lesser maintenance costs.
