Single Cartridge Seal SPW132 – High-Performance Mechanical Seal
Single Cartridge Seal SPW132 – High-Performance Mechanical Seal
Overview
HydroMax Seal SPW-132 | Compact Single Cartridge Seal for Plan 32 Applications
The SPW-132 is a compact single-cartridge mechanical seal featuring a multi-port flush ring integrated into the gland plate. Specifically designed for equipment with limited cross-sectional space, this seal is compatible with API610 Ed.5 onwards. It supports API Plan 32 arrangements, making it ideal for systems handling process fluids with suspended solids and particles.
This stationary cartridge seal is fully assembled and engineered for high efficiency and ease of installation in small seal chambers.
Product Description
Design Features
- Multi-port flush orifice provides a uniform “shower” of clean fluid over the inboard seal faces for Plan 32 systems
- Large 1/2″ NPT seal port orifices for optimal flow and system compatibility

Equipment & Use-Case Scenarios
- Single-seal cartridge installations using API Plan 32 flush systems
- Applications with fluids containing suspended solids or abrasive components
- Pumps and other rotating equipment with limited seal chamber cross-sections
- Services where reduced maintenance and high reliability are required
Why It Fits These Applications
- Plan 32 flush orifice: Directs clean flush fluid across seal faces to support lubrication and heat dissipation
- Integral vortex breakers: Improve fluid flow dynamics in the seal chamber and help manage solids without aggressive impact
- Compact cartridge design: Allows installation in smaller seal cavities without sacrificing performance
- Hydraulically balanced face configuration: Enhances pressure handling and operational stability
- Multi-spring design: Promotes even loading across seal faces and isolates springs from process fluid
- Monolithic seal faces: Provide durability and thermal stability in moderate to elevated temperature services
Installation Guidelines
Pre-Installation Preparation
Thoroughly clean and inspect the pump shaft, seal chamber bore, and gland surfaces. Remove corrosion, scoring, or debris to ensure accurate alignment and full face contact.
Seal Installation
Install the SPW132 cartridge seal into the seal housing, ensuring the flush orifice and vortex breaker features are correctly oriented for the API Plan 32 piping arrangement. Secure the cartridge evenly to the specified torque values and verify stable positioning.
Alignment & Fit
Confirm that the stationary seat and rotary faces are properly aligned within the housing to maintain uniform contact and reliable sealing performance.
Startup Procedure
Initiate flush fluid circulation before bringing the equipment to operating speed and pressure. Monitor the seal area for leakage, vibration, or abnormal temperature during initial operation before committing the system to full duty.
Maintenance & Inspection Best Practices
- Routine Visual Inspections: Regularly observe the seal area for signs of leakage, vibration, or unusually high temperatures
- Seal Face Monitoring: During scheduled maintenance, inspect faces for wear, scoring, or buildup of deposits
- Vortex Breaker Assessment: Check vortex breaker components for particle buildup or erosion that might reduce flow efficiency
- Operating Logs: Maintain records of pressure, temperature, and shaft speed to support predictive maintenance
- Spare Parts Inventory: Keep replacement O-rings, springs, seal faces, and cartridge components available to reduce downtime
Service & Support Options
- Application Review: Confirm materials and seal configuration are compatible with your fluid chemistry and operating conditions
- Installation Assistance: Technical guidance to ensure correct installation and reliable first-run performance
- Preventive Maintenance Scheduling: Establish inspection and parts replacement intervals based on duty cycles and operating history
- Seal Upgrade Evaluation: If operating conditions become more demanding (higher pressures, abrasive solids, elevated temperatures), consider alternate materials or enhanced designs to maintain performance
