Hydraulic Motor Spool Valve Motor BM3 motor is a spool valve with 2 radial ball-bearing type motor. And can bear bigger radial force. Characteristic features： It adapts the gerolor design, which has a higher distribution accuracy and Mechanical efficiency. Supported by double ball-bearing, the shaft can carry bigger radial force than BM2 motor. Credible design for shaft seal, which can bear high pressure and be used in parallel or in series. Direction of shaft rotation and speed can be controlled easily and smoothly. Best combination of efficiency and economy in medium duty applications.

Intermittent means the entrance of maximum pressure; continuous working pressure means the differential pressure. 2. Motor should not work under the highest pressure and the maximum speed. 3. The running time should not exceed 10% under intermittent working conditions. 4. The Maximum working temperature is 80℃. 5. The maximum allowable back pressure is 10Mpa, but the recommended back pressure should not exceed 5MP, a leaking pipes is needed when exceeding. 6. One hour running time under 40% of maximum working pressure is recommended before full capacity working. 7. Recommending N68 anti-wear hydraulic oil, viscosity 37-73cSt, cleanliness ISO 18/13.
