Sommario/riassunto |
|
Written by one of the world's foremost authorities on pumps, this first volume in Gulf PublishingCompany's Gulf Pump Guides series covers the design, application and troubleshooting forprogressing cavity pumps, downhole pumps and mudmotors. There is no other volume offeringa more 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. |
