GM series radial piston hydraulic motor
1. Jointly developed with USA company
2. Completely interchanageable with original
3. High mechanical efficiency, high starting torque (at startup mechanical efficiency above 0.92)
4. Flat with simple, reliable converters to improve sealing performance, and thus low-speed stability is good, very little leakage. Volumetric efficiency above 0.97
5. Due to the structure to reduce friction losses, improve sealing performance, low-speed stability and thus the motor can operate smoothly 1r/min operating conditions
6. As piston ring and bearing sleeve through the card firmly affixed there is no gap, so the motor can do pump running conditions, when the inlet is closed motor operating conditions in the free round of high-speed operation
7. This series motor with the original appearance and installation dimension Italy SAI's basically the same performance parameters and the original fitted Italy SAI close, is an ideal choice to replace imported motor

feature:
1. It reduces friction loss in force transmission because of no side force between piston and swing cylinder, hydrostatic balance designed in piston foot, transferring torque force through roller bearing. GM series hydraulic motors have high mechanical efficiency and high starting torque.
2. Flat distributor is simple, reliable and good seal, little leakage, no leakage between piston and swing cylinder through using plastic seal ring, so there motors have high volumetric efficiency.
3. Because of reducing friction loss in configuration, improving seal ability, these motors have good characteristic of low speed stability, can run steadily in 1 R/MIN condition, and have large speed range.
4. There is no gap between piston and bearing cover connected by ring clip, so these series motors can run as pump and can run with high speed when inlet is sealed.
5. There series motors have high pressure, with the Max. Pressure 45Mpa, light weight, small volume, high power.
