Gulf Pump Guides: Progressing Cavity Pumps, Downhole Pumps and - Mudmotor

Klappentext Written by one of the world's foremost authorities and instructors on pumps, this first volume in Gulf Publishing Company's new GULF PUMP GUIDES series covers the design, application and troubleshooting for progressing cavity pumps, downhole pumps and mudmotors. There is no other volume offering such a comprehensive, easy-to-understand and hands-on coverage of these types of pumps. As they become more and more widely used in the petrochemical industry, and other industries, knowledge of their design and application will become increasingly more important for the engineer. Zusammenfassung Covers the design! application and troubleshooting for progressing cavity pumps! downhole pumps and mudmotors. This title offers a comprehensive! easy-to-understand and hands-on coverage of these types of pumps.
