DIN ISO 3019/3 LSHT Hydraulic Motors RM80N Radial Piston Motors Hydraulic characteristic values: RM 3 Geometric displacement (cm /rev): 81 Theoretical specification torque (Nm/bar): 1.29 Average specification torque (Nm/bar): 1.15 Peak pressure* (bar): 400 Max. operating pressure** (bar): 315 Continuous pressure (bar): 250 Max. operating torque (Nm): 365 Continuous torque (Nm): 290 Drain line pressure (bar) max. 1: max. 1 Hydraulic fluid temperature range (K): 243 to 363 (°C): -30 to +90 2 Viscosity range (mm /s): 20 to 150 2 (maximum 1000 mm /s at start) Pressure fluids: HM and HV, definition to CETOP RP 75 H (mineral oil based fluids). Mineral oil H-LP in conformity with DIN 51524 part 2. Bio-degradable fluids available on request. * Definition according to DIN 24 312. Peak pressure = Pressure exceeding the maximum operating pressure for a short time at which the motor remains able to function. ** 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 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. Filtering: Max. permissible degree of contamination of the pressure fluid according to NAS 1638 class 9. Filters with a minimum retention rate of β ≥100 recommended. 10 For a long service life we recommend filtering acc. to NAS 1638 class 8 and filters with a minimum retention rate of β ≥100. 5 Characteristic values according to VDI 3278 Weight (kg): 40.0 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 : 800 2 Moment of inertia (kgm ): 0,00017 Continuous power (kW): 12.0 Intermittent power (kW): 15.0 RM 80 NZA1 www.jbj.co.uk/hydraulic-motors.html #DriveLineHarmony 27
