IMB series Fixed Displacement High Torque Radial Piston Hydraulic Motor

The IMB fixed displacement hydraulic motor comes with the hydrostatical balance between the connecting rod and eccentric wheel, so as to effectively prevent the crank throw of the crankshaft type hydraulic motor from being overwhelmed by the roller. Hence, this hydraulic motor can enjoy high pressure, high power and other advantages because of this design.

The connecting rod and piston of this hydraulic motor undergoes special treatment process and features hydrostatic balance between them, thus ensuring reduced friction loss in the load transmission and, and decreased force between piston and cylinder wall, as well as little wear between the piston and cylinder wall.

The piston seal ring designed with special structure greatly improves the volumetric efficiency and lowers the friction of the hydraulic motor. In addition, the distributor with hydrostatically balanced shaft can rotary without connection, thereby reducing the noise and resistance and prolonging the service life.

As the shape, characteristics and data of our IMB series fixed displacement hydraulic motor are similar to that of the Staffa HMB series motor, so it can substitute the imported one. Due to these advantages, this low speed high torque hydraulic motor is widely applicable to the hydraulic transmission of deck machinery, construction machinery and equipment, plastic injection machine, heavy metallurgical machinery.

Model Options
1. INI hydrostatic balance low speed, high torque model
2. Type
3. Nominal displacement
4. Output shaft
a. P-Parallel keyed shaft(numbers stand for the kinds of shaft)
b. T-Taper key shaft
c. S-Spline Shaft(1 stand for BS3550 standard shaft, 2 stand for DIN5480)
d. Q-Internal Spline Shaft

For example, IMB 325 5400 P3 indicates that the motor is an IMB 325 type hydrostatic balance low speed and high torque motor. The number 5400 contained in the model represents that the hydraulic motor comes with a nominal displacement of 5400ml/r. In addition, P3 means that the output shaft adopts three kinds of parallel keyed shaft.
