Equipment & Use-Case Scenarios
- Parallel-shaft centrifugal and process pumps needing consistent internal wet sealing
- Services with chemically aggressive or moderately contaminated liquids
- Applications requiring durable, balanced sealing under varying pressures and speeds
- OEM replacement and routine maintenance in standard working length seal cavities
Why It Fits These Applications
- Multi-spring design: Provides consistent face loading across a range of operating conditions, enhancing reliability
- Monolithic rotary head: Improves thermal strength and structural integrity during service
- Set-screw drive: Offers secure mechanical engagement to the shaft
- Internal wet configuration: Utilises process fluid for lubrication and heat removal
- Stationary seat included: Simplifies installation and reduces assembly time
- Interchangeability: Can substitute common component seals without modification in many applications
Installation Guidelines
Pre-Installation Preparation
Thoroughly clean and inspect the pump shaft, seal chamber bore, and gland surfaces. Remove corrosion, debris, and surface defects to ensure proper sealing surface contact and alignment.
Seal Installation
Slide the IPW-022 seal onto the shaft and position it correctly in the seal chamber. Ensure the multi-spring assembly and set screws are oriented correctly. Tighten the set screws evenly without over-torquing to secure the rotary head to the shaft.
Alignment & Fit
Check that the stationary seat and seal faces are correctly aligned within the housing to maintain even face loading.
Startup Procedure
Once installed, gradually bring the pump up to operating speed and pressure. Observe the seal area for any signs of fluid leakage, vibration, or abnormal temperature before placing the equipment into full duty.
Maintenance & Inspection Best Practices
- Routine Visual Checks: Periodically inspect the seal region for leakage, abnormal heat, or vibration
- Seal Face Inspection: During planned maintenance, review seal faces for wear, scoring, or deposit build-up
- Secondary Seal Integrity: Ensure set screws and secondary parts remain secure and undamaged
- Operating Logs: Track pressure, temperature, and shaft speed to support predictive maintenance
- Spare Parts Planning: Keep replacement stationary seats, springs, and seal faces available to minimise downtime
Service & Support Options
- Application Review: Verify that the selected materials and sealing configuration match fluid chemistry and operating conditions
- Installation Assistance: Technical guidance to ensure correct orientation and secure engagement
- Preventive Maintenance Scheduling: Establish regular inspection and replacement intervals based on operating history and duty cycle
- Upgrade Evaluation: If service demands intensify, evaluate alternate materials or enhanced designs to maintain performance
