Type A | Category 2/3 Contacting Wet Seals – Arrangement 1

The Flexaseal Style HPPS addresses the challenges of sealing high pressure process fluids with low specific gravities in refinery, pipeline, and power generation industries. The seal design is highly adaptable to meet specific application needs and comes standard with:

  • High-duty seal face materials
  • Precision laser-etched lubrication-enhancing features on the mating ring amplify film load support, critical to long life in thin fluids like light hydrocarbons and high temperature water.

    ype A | Category 2/3 Contacting Wet Seals
  • Stationary design allows for high-peripheral speeds
  • Robust metal-to-metal torque transfer to flexible stationary element eliminates wear-induced seal hang-up.
  • Metal oxide coated dynamic O-ring surfaces prevent fretting wear from process vibrations

Tailored Solutions for Enhnaced Reliability

Style HPPS seals can be configured with optional features to meet application specific requirements, including:

  • Floating carbon bushing inboard and/or outboard for seal isolation from process and leakage containment
  • Radial or axial pumping ring for Plan 23 circulation in hot processes
  • Multi-point flush injection for distributed cooling and vapor bubble elimination
  • Style CPH outboard non-contacting containment seal for emissions control with API Plan 72/75/76
