HydroMax Seal – SPW682-53

Double Cartridge Mechanical Seal for API Plan 53 Systems

The SPW682-53 from HydroMax Seal is a high-performance double cartridge mechanical seal, fully designed in accordance with API682 standards, and engineered for mission-critical Oil & Gas applications. Developed for use with API Plan 53A, 53B, and 53C configurations on API610 V8 and newer process pumps, this seal ensures superior containment, cooling, and pressure control.

This advanced stationary seal assembly incorporates a bi-directional barrier fluid pumping ring and is suitable for slurry, high-speed, or high-temperature applications.

Product Description

Design Features

  • 1/2″ NPT Barrier Fluid In (BI) and Out (BO) orifices for efficient flow in Plan 53 or 52 systems
  • Barrier fluid deflector integrated into the gland plate — ensures directed fluid flow to inboard faces and thermal removal from outboard seal faces
  • Quench (Vent) and Drain orifices for Plan 62 compatibility — includes outboard floating restriction bush to maintain seal integrity upon primary seal failure
  • Integrated vortex breakers in the gland for handling slurries and process fluids with solids
  • API682-compliant radial clearances between rotating and stationary elements for operational stability
  • Monolithic seal faces are designed to withstand elevated temperatures
  • Stationary self-aligning seal face is ideal for high-speed operations
  • Multi-spring configuration — springs are positioned outside the process fluid for enhanced durability
  • High-efficiency bi-directional pumping ring for barrier fluid circulation in pressurized dual seal systems
  • Fully compatible with HydroMax Seal’s Plan 53A/B/C support systems, including heat exchangers, reservoirs, and flow controls
