It''s a perfect and economical choice to replace Italy SAI GMseries. And it has the followingmodels: XHS05,XHS1,XHS2,XHS3,XHS4,XHS5,XHS6,XHS7,XHS9

Its main characteristics:

1. It has very high mechanical efficiency and comparatively higherstarting torque (at least 0.92 mechanical efficiency when itstarts).The reason is: there’s no side force between piston andcylinder; the piston bottom is designed into static pressurebalance; the torque between piston and crankshaft is transferredthrough the rolling bearing which reduces friction loss duringforce transferring process.

2. It has very high volumetric efficiency (could reach 0.98)because of the following: the distributor with flat surface (patenttechnology) is designed simplely, reliablely, with perfect sealingand few leakage; the plastic piston ring is used between the pistonand the tilt cylinder to provide no leakage.

3. It runs stably under low speed and it can stably run under1r/min working condition. And it provides wide adjusting range ofspeed. The reason is that it reduces friction loss and improvessealing performance in structure design.

4. It could run under pump working condition as there’s noclearance between its piston and bearing bushing because they arejointed firmly through a snap ring.

5. It has high pressure, light weight, small size and high specificpower.

6. It works reliably, with long life and low noise; its drivingshaft allows bearing radial load; and it could run reversibly.

These characteristics are based on its simple and reasonable designand using bearing with large load ability

It has wide application range. It can be applied in the hydraulictransmission systems of various machines such as plastic injectionmachine, light industry machine, construction and engineeringmachine, metallurgical equipment, petroleum equipment, coal mineequipment, geological prospecting equipment, railway equipment,ship equipment, environment protection equipment, machine tool andagricultural machine.
