Preventative Maintenance for a Sanitary BPRV
Preventative maintenance depends on the customer. Some run to failure while others change out every 2 years.
Sanitary Preventive Maintenance is a planned, routine approach to maintaining equipment and systems in a way that ensures cleanliness, hygiene, and contamination control, especially in industries where sanitation is critical.
In this video, Karl walk you through the preventive maintenance process for our sanitary BPRV, along with key insights to help optimize performance and longevity.
Sanitary Preventative Maintenance Overview
While maintenance frequencies vary across the biopharmaceutical industry, the Mark 95 and Mark 96 series are designed for high longevity. Common industry practices range from replacing seals every six months to two years, while some facilities choose to “run to failure”.
Performance Benchmarks
The video highlights two notable examples of long-term reliability:
- East Coast Biopharm Facility: Out of a population of over 100 regulators used in clean steam and biopharm services, only one failed over a nine-year period.
- West Coast Biopharm Facility: This customer currently uses a four-year PM cycle for their control valves and is considering extending that cycle to seven years based on the durability of the components.
Key Components to Inspect
- The Diaphragm: This is the primary wear item and the key to the valve’s longevity.
- O-ring Seals: While these are also wear items, they generally experience less wear than the diaphragm.
Recommended Maintenance Strategy
Rather than adhering to a rigid schedule, a judgment-based approach is recommended:
Initial Inspection: Inspect the diaphragm and o-rings at your facility’s standard PM interval for this class of valve (e.g., every six months).
Assessment: If the components show no visible signs of wear, they can be reinstalled for the next cycle.
Data-Driven Adjustments: Use these inspections to build a history of the valve’s performance in your specific application, allowing you to confidently extend the time between maintenance cycles.
