Durable Single Cartridge Mechanical Seal SPW682-132
Durable Single Cartridge Mechanical Seal SPW682-132
Overview
HydroMax Seal SPW682-132 | API682-Compliant Single Cartridge Seal for Plan 32 Systems
The SPW682-132 is a high-performance single-cartridge mechanical seal designed with a multi-port flush ring in the gland plate and a unique combination of segmented and floating outboard restriction bushes. Engineered to meet API682 specifications, this seal is optimized for critical Oil & Gas applications and is compatible with API Plan 32 arrangements on API610 V8+ process pumps.
The stationary cartridge configuration is fully assembled and tested, making it an ideal solution for high-speed and particle-laden process fluid environments.

Typical Applications & Industry Use Cases
The SPW682-132 Single Cartridge Mechanical Seal is a high-performance, API 682–compliant single-cartridge seal engineered for use with API Plan 32 piping arrangements on API 610 V8 and newer process pumps. It is designed to deliver reliable sealing performance in demanding process environments, particularly where suspended solids are present, and continuous flush circulation is required for cooling and lubrication.
Industries Served
Oil and gas and hydrocarbon processing
Chemical processing facilities
Refining and petrochemical transfer systems
Water treatment and utility operations handling particulate fluids
General industrial pumping systems requiring API-level sealing reliability
Equipment & Use-Case Scenarios
- Single-seal configurations on API 610 process pumps where API 682 compliance is required
- Applications using Plan 32 flush systems for improved seal-face cooling and lubrication
- Services handling suspended solids or contaminants that benefit from distributed flush delivery
- Installations where fully assembled cartridge seals reduce installation time and minimize assembly errors
Why It Fits These Applications
- Multi-port flush orifice delivers an even spray of clean fluid across the inboard seal faces, improving cooling and reducing solids-related wear
- Integrated quench and drain ports compatible with Plan 62 and Plan 52 arrangements, with a deflector that directs steam or buffer fluid effectively
- API 682–compliant internal clearances enhance alignment, stability, and long-term performance
- Monolithic seal face construction improves thermal resistance and durability in elevated-temperature services
- Segmented and floating restriction bush design enhances sealing reliability in demanding process conditions
Installation Guidelines
Pre-Installation Preparation
Thoroughly clean and inspect the pump shaft, seal chamber bore, and gland face. Remove corrosion, debris, or surface damage to ensure proper alignment and sealing integrity.
Cartridge Installation
Carefully install the SPW682-132 cartridge into the seal chamber, ensuring the multi-port flush ring and all ports are correctly oriented to match the selected Plan 32 piping arrangement. Secure all fasteners according to specification.
Support-Fluid Connections
Connect flush, quench, and drain lines in accordance with the applicable API piping plan. Prime and vent all lines to remove trapped air and confirm consistent fluid flow before startup.
Controlled Startup
Start support-fluid circulation first, then gradually bring the pump to operating speed. Monitor flush flow, seal-face temperature, vibration, and leakage during initial operation.
Maintenance & Inspection Best Practices
- Monitor flush and quench system performance, including flow rates, pressure, and fluid cleanliness
- Perform scheduled inspections during shutdowns to check seal faces, springs, restriction bushings, and secondary seals for wear or corrosion
- Maintain operating logs tracking pressure, temperature, speed, and fluid properties to support predictive maintenance
- Replace secondary seals and filters on a preventive schedule to maximize service life
- Reassess seal materials and support-fluid plans if process conditions change, such as increased temperature, pressure, or solids content
Service & Support Options
- Application reviews to confirm material compatibility and piping plan suitability
- Spare parts planning to ensure replacement faces, elastomers, springs, and hardware are readily available
- Installation and commissioning support to ensure correct orientation and first-run performance
- Preventive maintenance programs based on operating history and duty conditions
- Evaluation of upgraded materials or configurations for more severe or evolving service requirements
