Modular hydraulic motors MS8 - MSE8 OCLAIN HYRAULICS INTROUCTION Given their optimized and modular design capable of deliverg high performance, motors from the MS Classic range have established themselves as a benchmark on the hydraulic motor market. MS Classic range can be characterize by: Compacity Optimized cost ower density The MS HighFlow motor range has all the qualities that have made the MS Classic range such a success: they are modular and robust, offerg performance advantages (speed and power) at the same time. MS HighFlow motor range is different by: Integrated exchange valve New ports geometry New valvg 2 11/7/218
