Reliability & Engineering Risk Analysis

Failure Mode & Root Cause

Seal degradation and leakage

Cause: Chemical incompatibility with dispensed fluids leading to swelling, hardening, or cracking of elastomeric seals; excessive pressure cycling causing fatigue failure; improper installation leading to misalignment and uneven wear

Valve sticking or binding

Cause: Particulate contamination in fluid stream causing buildup on valve seats and moving parts; corrosion from aggressive chemicals or moisture ingress; lack of lubrication on mechanical linkages; thermal expansion/contraction causing tolerance issues

Maintenance Indicators

Visible fluid leakage around seals, connections, or housing indicating seal failure or component damage
Irregular dispensing patterns, inconsistent flow rates, or unusual noises (clicking, grinding, hissing) during operation suggesting internal obstruction or mechanical issues

Engineering Tips

Implement proactive seal replacement based on chemical compatibility charts and service hours rather than waiting for failure; use compatible lubricants on moving parts and establish regular cleaning protocols to prevent contamination buildup
Install proper filtration upstream to remove particulates; conduct regular calibration checks to ensure consistent performance; maintain environmental controls to prevent moisture ingress and temperature extremes that accelerate degradation
