SPW682-132 – Single Cartridge Mechanical Seal
Overview
The SPW682-132 from HydroMax Seal is a robust single-cartridge mechanical seal engineered to meet the rigorous standards of API682, making it ideally suited for applications in the Oil & Gas industry. Designed for use in API Plan 32 piping arrangements on API610 V8 and newer process pumps, this seal offers superior sealing performance in challenging operating environments.
This complete cartridge solution features a stationary seal design and incorporates critical best-practice elements to ensure optimal reliability, thermal performance, and resistance to process contaminants.
Product Description
Design Features
- Multi-port flush orifice for Plan 32 systems — delivers a uniform spray of clean, cooling, and lubricating fluid to the inboard seal faces, especially beneficial for process media with suspended solids
- Quench and drain orifices support Plan 62 or Plan 52 systems — integrated deflector guides steam or buffer fluid to the inboard faces
- 1/2″ NPT large seal port orifices for efficient fluid handling
- Gland plate with multi-port flush ring ensures consistent flow across the sealing interface
- Radial clearances between rotary and stationary components conform to API 682 best practice standards
- Monolithic seal faces enhance thermal resistance and durability under high-temperature conditions
- Self-aligning stationary face design — optimized for high-speed applications
- Multi-spring configuration with isolated springs (non-contact with process fluid) for extended service life
- Advanced restriction bushing assembly — includes both a segmented bush and a floating restriction bush for improved outboard sealing efficiency
- Fully compatible with HydroMax Seal’s Plan 32 accessory kit, featuring an integrated pressure gauge, flow meter, valves, and an inline strainer
