Installation Guidelines
Pre-Installation Preparation
Clean and inspect the pump shaft and seal chamber thoroughly. Remove any debris, corrosion, or surface damage to ensure proper alignment and sealing integrity.
Seal Installation
Install the RPW-020 seal assembly into the Fristam pump seal chamber, confirming correct orientation. No pump modification is required, as the seal is designed as a direct replacement.
Alignment and Fit
Verify that the rotary and stationary faces are properly aligned and that the spring mechanism is correctly seated to ensure consistent contact and sealing performance.
Startup Procedure
After installation, bring the pump up to operating conditions gradually. Monitor for leakage, vibration, or abnormal temperature at the seal area before placing the pump into full service.
Maintenance & Inspection Best Practices
- Perform routine visual checks for leakage, noise, vibration, or elevated temperatures near the seal area.
- Inspect seal faces and stationary components during scheduled maintenance for wear, scoring, or deposits.
- Check the spring condition to ensure proper compression and replace components if wear is detected.
- Maintain operating logs of pressure, temperature, and speed to support predictive maintenance.
- Keep replacement seal components available to minimize downtime during servicing.
Service & Support Options
- Application reviews to confirm material compatibility with process fluids and operating conditions
- Installation assistance to ensure correct placement and reliable first-run performance
- Preventive maintenance planning based on duty cycles and operating history
- Evaluation of alternative materials or seal designs if service conditions become more demanding
