THE PUMP PROFESSOR’S DESK
Technical articles and practical guidance from Process Containment Solutions (PCS).
ANSI/ASME and ISO process-pump standards provide recognised engineering frameworks for design, dimensions and technical requirements. This article explains what the standards actually specify, how they relate to reliability and efficiency, and why correct pump selection still depends on the application.
Repair quality affects more than the component that failed. This article explains how pump condition, mechanical seal performance, bearing reliability and functional testing should be assessed together to limit the risk of repeat interventions.
Every pump repair leaves useful evidence. When repair findings, intervention history and test results are recorded and reviewed over time, they can help maintenance teams identify repeat issues, plan interventions earlier and make better repair, replacement and reliability decisions.
MTBR and MTBF help maintenance teams understand how often pumps and mechanical seals fail, require intervention or show signs of declining reliability. Used correctly, these metrics support better shutdown planning, spares management and root cause investigation, helping plants move from reactive seal replacement to structured reliability management.
API 682 gives engineering, maintenance and procurement teams a structured way to assess mechanical seal type, arrangement, piping plan and documentation requirements against real service conditions. PCS explains why standards-led seal selection supports containment, reliability and lifecycle control in critical pump applications.
Long-term seal reliability in severe methanol service depends on correct seal selection, disciplined reconditioning, and evidence-based MTBR/MTBF tracking. PCS examines how Flowserve BRC metal bellows seals support reliability in demanding petrochemical duty.
