Description
Selecting “the right pump for the job” is an essential and complex undertaking throughout all chemical process industries (CPI) applications. This Chemical Engineering Guidebook covers a range of essential topics associated with proper pump selection, operation and maintenance.
Several articles focus on sizing, installing and troubleshooting pumps, including details on vacuum pumps, diaphragm pumps, magnetically driven pumps and others. Others discuss variable-frequency drives, and process safety considerations to ensure safe operation and avert catastrophic failure over the lifecycle of the pump systems.
Included are specific recommendations to carry out pump maintenance and proper lubrication and include tips for overcoming the challenges associated with high-shear mixing, engineering considerations for piping system design, strategies for optimal process plant layout, lifecycle-cost calculations and more.
