LSHT Hydraulic Motors KM90 Radial Piston Motors Hydraulic characteristic values: KM 3 Geometric displacement (cm /rev): 89 Theoretical specification torque (Nm/bar): 1.41 Average specification torque (Nm/bar): 1.27 Peak pressure* (bar): 250 Max. operating pressure** (bar): 210 Continuous pressure (bar): 140 Max. operating torque (Nm): 266 Continuous torque (Nm): 178 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): 21.4 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 : 900 2 Moment of inertia (kgm ): 0,00039 Continuous power (kW): 8.5 Intermittent power (kW): 100 Flange DIN-ISO 3019/2 KM 90 ZAF End cover A 20 www.jbj.co.uk/hydraulic-motors.html #DriveLineHarmony
