DIN ISO 3019/3 LSHT Hydraulic Motors RM250N Radial Piston Motors 36 Drain line pressure (bar) max. 1: max. 1 2 Viscosity range (mm /s): 20 to 150 Hydraulic characteristic values: RM 3 Geometric displacement (cm /rev): 251 Theoretical specification torque (Nm/bar): 4.0 Peak pressure* (bar): 350 Average specification torque (Nm/bar): 3.7 Continuous pressure (bar): 200 Max. operating pressure** (bar): 315 Max. operating torque (Nm): 1165 Continuous torque (Nm): 740 Hydraulic fluid temperature range (K): 243 to 363 (°C): -30 to +90 2 (maximum 1000 mm /s at start) Mineral oil H-LP in conformity with DIN 51524 part 2. Bio-degradable fluids available on request. Peak pressure = Pressure exceeding the maximum operating pressure for a short time at which the motor remains able to function. Pressure fluids: HM and HV, definition to CETOP RP 75 H (mineral oil based fluids). HFC Reduce HFC pressure to 70 %. Check the bearing service life. HFD Viton seals are required. Definition to CETOP RP 77 H ISO/DIS 6071. * Definition according to DIN 24 312. Characteristic values according to VDI 3278 Weight (kg): 58.0 Mounting position as : required Direction of rotation, if viewed at the shaft end clockwise: flow from connection 2 to connection 1, anti-clockwise: flow from connection 1 to connection 2 Operating speed range (rpm): 5 : 600 2 Moment of inertia (kgm ): 0,00023 Continuous power (kW): 24.0 Filtering: Max. permissible degree of contamination of the pressure fluid according to NAS 1638 class 9. Filters with aminimum retention rate of β ≥100 recommended. 10 For a long service life we recommend filtering acc. to NAS 1638 class 8 and filters with aminimum retention rate of β ≥100. 5 ** If the sum of inlet pressure and outlet pressure is higher than the peak pressure, please consult jbj Techniques technical office, telephone: +44 (0)1737 767493 or email: info@jbj.co.uk Intermittent power (kW): 30.0 RM 160 NZA1
