Single Cartridge Seal: SPW682-131

HydroMax Seal SPW682-131 | API682 Stationary Cartridge Seal for Plan 31 Systems

The SPW682-131 is a single-cartridge mechanical seal designed to comply with API 682 specifications, specifically for Plan 31 systems in API 610 V8+ process pumps. Built to handle process fluids containing suspended particles, it features integrated vortex breakers and a dual-restriction bush setup to maintain system integrity in demanding oil and gas applications.

Product Description

Design Features

  • Flush orifice for Plan 31 systems: Prevents ‘shot blasting’ of the stationary face by directing fluid correctly when handling particulate-laden liquids
  • 1/2″ NPT port connections for large flow capacity
  • Quench and Drain orifices for Plan 62/52 with integral deflector for optimal fluid direction
  • Gland plate with vortex breakers for turbulence control and particle management
  • Compliant radial clearances per API 682 for improved seal face alignment
  • Monolithic seal faces for thermal performance and face integrity
  • Self-aligning stationary design to accommodate shaft-to-chamber misalignment
  • Multi-spring design with springs isolated from process fluid for longevity
  • Dual outboard restriction bush: Segmented and floating for superior safety and reliability
  • Compatible with HydroMax Cyclone Separator systems and sample pots for Plan 31
