DMVA Short Description-1

Short description Axial piston motor DMVA --- The Liebherr axial piston motors in the DMVA series are designed as swashplates for open and closed circuits and were specially developed for use in mobile machinery in harsh environments. The inverse drive with a swivel angle of 22° is very efficient and has a very high power density, making it ideal for applications that require a variable displacement to hydraulic motor. The variable displacement flange motors are available in nominal sizes ranging from 108 to 370. The nominal pressure of the units is 6,527 psi (450 bar) and the maximum pressure is 7,252 psi (500 bar) absolute. The through-drive capability can be used for mounting a brake or tandem units (axial piston multi-circuit motor). The DMVA series is available with the most common controls. Speed sensor or preparation for speed sensor available on request. Valid for: DMVA 108 involute gear hub profile DMVA 165 involute gear hub profile DMVA 215 involute gear hub profile DMVA 370 involute gear hub profile Features: D series Open and closed circuit Control types: Various control types can be selected Pressure range: Nominal pressure pN = 6,527 psi (450 bar) Maximum pressure pmax = 7,252 psi (500 bar)
