Pumps: Selection, Maintenance and Safety- Volume 2


SKU: CE149 Category:


This Chemical Engineering Guidebook provides useful engineering recommendations for selecting, operating, maintaining and troubleshooting pumps to ensure safe, cost-effective operation.

Several articles focus on reciprocating pumps and positive-displacement pumps, while others focus on selection and fabrication of pumps for hygienic applications in biopharmaceutical, food-and-beverage and other applications that carry out pristine processing.

Suggestions on sizing and specifying pumps, and calculating the appropriate net positive suction head (NPSH) to meet the application are included. Guidance is provided for selecting sealless pumps to ensure full product containment, and for carrying out condition monitoring of pumps and other rotating machinery.

Also included are engineering recommendations for setting appropriate foundations for equipment (to minimize vibration and misalignment), and a review of principles of piping and instrumentation diagrams (P&ID) development, and coupler technologies that ensure secure chemical handling. There is also review of best practices in commissioning capital equipment, and the use of corrosion data to monitor aging assets.

Delivered in a PDF format, 156 pages.
