Utility and manufacturing applications
Equipment & Use-Case Scenarios
- Parallel-shaft centrifugal and process pumps require reliable internal wet sealing
- Applications involving chemically aggressive or corrosive liquids
- General industrial equipment where compact, balanced sealing is preferred
- OEM replacements or upgrades in standard working length seal cavities
Why It Fits These Applications
- Multi-spring configuration: Ensures balanced face pressure across varying operating conditions, enhancing sealing performance
- Monolithic rotary head: Improves thermal stability and structural integrity during service
- PTFE wedge packing: Provides superior chemical resistance compared with standard elastomer secondary seals
- Set-screw driven: Offers secure and reliable mechanical engagement to the shaft
- Interchangeability: Can replace JC Type 9 component seals without modification, facilitating inventory and maintenance flexibility
- Supplied with a stationary seat: Simplifies installation and readiness for common internal wet applications
Installation Guidelines
Pre-Installation Preparation
Clean and thoroughly inspect the pump shaft, seal chamber bore, and gland surfaces. Remove any corrosion, debris, or surface damage to ensure proper sealing surface contact and alignment.
Seal Installation
Slide the IPW-021 seal onto the shaft and position it in the seal chamber with correct orientation. Confirm that the multi-spring assembly, PTFE wedge packing, and set screws engage properly without over-torquing.
Alignment & Fit
Ensure the stationary seat and seal faces are correctly aligned within the gland or housing to maintain even face loading and optimal contact.
Startup Procedure
Once installed, introduce the process fluid and gradually bring the equipment up to operating speed and pressure. Monitor the seal area for leakage, vibration, or temperature anomalies before full duty operation.
Maintenance & Inspection Best Practices
- Routine Visual Checks: Observe the seal area for leakage or abnormal heat
- Seal Face Condition: Inspect seal faces periodically for wear, scoring, or deposits
- Secondary Seal Integrity: Check the PTFE wedge packing for signs of degradation, swelling, or distortion
- Operating Logs: Track pressure, temperature, and speed trends to support predictive maintenance
- Spare Parts Planning: Maintain replacement stationary seats, springs, and wedges to minimise downtime
Service & Support Options
- Application Review: Verify material compatibility and seal selection for specific fluid conditions and operating parameters
- Installation Assistance: Technical guidance to ensure correct orientation and secure engagement
- Preventive Maintenance Scheduling: Establish inspection and replacement intervals based on operating history
- Upgrade Evaluation: If service conditions become more demanding, assess alternative materials or enhanced seal designs to maintain reliability
