There is hardly any industry, where fluid power application does not exist. Each and every application has a Pump involved and many cases a hydraulic motor too. Therefore, the global field population of Hydraulic Pumps and Motors is enormous. There are numerous Hydraulic Pump and Motor manufacturers in the world, in all the continents. The significant of them has been mentioned in this book. United States of America is the largest producer of hydraulic Pumps and Motors. The Fluid power industry involves millions of Jobs across the Globe. User base market for hydraulic pumps and motors are almost unlimited. Vocational and engineering schools barely mention Fluid Power application and usage of hydraulic pumps and motors. This book is designed to help the engineering schools to baptize their students with hydraulic Pumps and Motors and the industry as a whole. The book will put in touch the students with the actual pump and motor and their many applications. For those who are in Fluid Power industry, the book will provide variety of applications where hydraulic pumps and motors are profusely used.
