Optima’s Hydrostatic Transmission (HST) System
Hydrostatic Transmission system provides smooth and efficient power transmission by connecting the hydraulic pump and motor in a closed circuit. This system is widely used for the traveling function of many construction and agricultural machinery. We can offer displacements as follows: 90(71), 112, 125(110)cc/rev. Optima's Hydrostatic Transmission Systems HTS.09 and HTS.211 of its own development and design.
Application: Harvesters, mobile mowers, transit mixers
HST.09 for concrete mixer volume 9-12 m3 (Equivalent to Danfoss®: PV23, MF23)
HST.211 for concrete mixer volume 12-15 m3
HST.521 (125cc) for Harvesters
