The hydraulic speed variator is an unified hydrostatic transmission that consists of the radial piston pump or variable displacement pump as the primary pump operating a fixed displacement radial piston motor (secondary pump). The pump motor
system can be completely sectioned off in one case or housed in the same case and mounted on a fixed shaft. Hydrostatic gears
work according to the principle of hydrostatic transmission. The input shaft of the hydraulic speed variator conveys the continouos speed of the upstream motor to a variety of pistons that expand and compress the oil in the cylinders. By altering the oil pressure and flow rate, the speed of rotation transmitted to the output shaft changes as well. A wide range of hydrostatic speed variator options are available to you, such as gearing arrangement.
