Windust Hydraulics supply the the GM Series of radial piston motors, manufactured by SAI Hydraulics.
The GM Series is a range of fixed displacement motors with a design resulting from continuous improvement obtained from decades of experience in the field. High mechanical and volumetric efficiency and excellent cavitation resistance make them ideal products for any circuit that requires reliability, high performance, and speed control.
- Radial injection cylinder feed eliminates direct hydraulic axial loading of the motor casing
- Larger cylinder feed channels for reduced power loss with high flows
- Stronger castings and internal reinforcement ribbing: increased casing strength and stiffness for higher internal and external load capacity
- High load capacity bearings for applications requiring high lifetime, high power/pressure, high external loads
- Larger cylinder trunnions for increased strength and stiffness and reduced specific loads
- Cylinder trunnions with hydraulic balancing to reduce friction, wearing and heat generation, enabling operation with higher powers and improved efficiency
The GM3A range has:
- displacement options between 352 to 792cc
- peak pressure 350 to 450 bar
- max speed 500 to 700rpm
- torque 5.49 to 12.40 Nm/bar
