It has been the dream of engineers for years to devise an efficient method of transmitting rotary mechanical power that gives infinite smooth speed variation. Achieving this at a competitive price has been a difficult task, with the result being that most hydraulic machines offer low, inefficient performance.
IFIELD variable pump motor units, incorporating patented technology, have been developed over decades to give a level of efficiency and performance that surpasses all other known methods. These non-over-center units have been proven in arduous applications, such as mining, defence, and motor industries, resulting in high reliability and performance.
