Chemical Pump Failure Diagnostics: Cavitation, Leakage and Vibration

Most unplanned chemical pump shutdowns are not sudden events. Noise changes first, then temperature, then vibration, then flow. A structured approach that works backwards from symptoms is far more valuable than simply…

Wetted Materials and Shaft Sealing for Chemical Pumps

The same pump can last ten times longer in cooling water than in a hot chloride solution. More often than not, the difference comes down to two decisions: what the wetted parts…

Canned Motor Pumps: Zero-Leakage Handling of Hazardous Chemical Fluids

When the pumped fluid is highly toxic, corrosive, flammable, explosive, expensive, or simply cannot be released into the environment, the small permitted leakage of a conventional mechanical seal becomes unacceptable. A canned…

High-Speed Pumps in Chemical Plants: Service Conditions and Engineering Essentials

Hydrotreating, light-ends recovery, liquid ammonia transfer and high-pressure water injection all share a difficult profile: modest flow, very high head. A conventional multistage centrifugal pump becomes tall, heavy and maintenance-intensive. High-speed pumps…

Chemical Process Pump Selection: Matching Design to the Service

In a chemical plant, pumps are the heart of fluid movement. Unlike water supply duties, chemical process pumps handle corrosive, flammable, toxic, solids-laden or high-temperature fluids. A poor selection does not merely…
