Straight Talk on WOB-L Piston Pumps

Publisher: Combined Fluid Products Co.
A step-by-step guide for selecting the appropriate WOB-L piston pump for specific applications is presented in this paper, highlighting the versatility offered by these pumps. It compares the characteristics of the pumps based on WOB-L piston, rotary vane, articulated piston, diaphragm, and linear vacuum and pressure technologies, stating the applications they are best suited for. While it attempts to provide a thorough understanding of the functioning of WOB-L piston pumps with the help of illustrations, the paper lists the various engineering enhancements in WOB-L technology, along with the wide variety of applications of WOB-L piston pumps. The paper also states the top ten factors to be considered while specifying a WOB-L piston pump, explaining their significance, in addition to the top ten list of factors that cover most of the information a pump manufacturer would need to know to recommend or design the best pump for user's application in detail.
