Equipment & Use-Case Scenarios
- Parallel-shaft centrifugal and process pumps require a basic internal seal
- Services with clean to mildly contaminated liquids
- Applications under low to moderate pressure and temperature conditions
- Routine maintenance and part replacement in standard pumping systems
Why It Fits These Applications
- Single coil spring design: Delivers consistent radial load to maintain contact between seal faces
- Elastomeric secondary seals: Provide effective sealing to the shaft and housing surfaces
- Set-screw drive: Secures reliable mechanical engagement and straightforward installation
- Internal wet configuration: Utilises process fluid for lubrication and cooling
- Simple, robust construction: Ideal for standard industrial applications where minimal engineering support is needed
Installation Guidelines
Pre-Installation Preparation
Clean and inspect the pump shaft, seal chamber bore, and gland surfaces. Remove corrosion, debris, and surface irregularities to ensure proper sealing surface contact and alignment.
Seal Installation
Slide the RPW-010 seal onto the shaft into the seal chamber. Ensure correct orientation of the coil spring and elastomer components relative to the shaft and housing. Tighten the set screws evenly to secure the assembly without over-torquing.
Orientation Check
Verify that the seal’s orientation matches the intended direction of shaft rotation and fluid flow where applicable.
System Readiness
Confirm that the seal chamber is flooded with process fluid if required by your application and that all components are securely in place before starting the pump.
Maintenance & Inspection Best Practices
- Routine Visual Checks: Inspect the seal area for signs of leakage, vibration, or irregular temperature
- Seal Face Condition: During scheduled maintenance, check seal faces for wear, scoring, or deposits
- Secondary Seal Integrity: Inspect elastomeric components for hardening, cracking, or deformation and replace as needed
- Operating Logs: Track fluid pressure, temperature, and shaft speed to support predictive maintenance planning
- Spare Parts Inventory: Keep replacement springs, seal faces, and elastomeric elements on hand to minimise downtime
Service & Support Options
- Application Review: Confirm elastomer compatibility and overall seal selection for your specific fluid and operating conditions
- Installation Assistance: Technical guidance to help ensure correct orientation and secure engagement
- Preventive Maintenance Scheduling: Set inspection and replacement intervals based on duty conditions
- Seal Upgrade Evaluation: If operating conditions intensify, assess alternative designs or materials for improved performance
