OMP
Blince
OMP motors use a gerotor gear set and shaft flow distribution. The catalogue separates shaft configurations, so the numeric limits shown here must remain attached to the stated shaft table rather than every motor bearing an OMP label.
| Model | Displacement cm3/rev | Continuous pressure differential MPa | Continuous torque N m | Maximum continuous speed rpm |
|---|---|---|---|---|
| OMP 36 | 36 | 12.5 | 55 | 1500 |
| OMP 50 | 51.7 | 14 | 100 | 1150 |
| OMP 80 | 77.7 | 14 | 146 | 770 |
| OMP 100 | 96.2 | 14 | 182 | 615 |
| OMP 125 | 120.2 | 14 | 236 | 490 |
| OMP 160 | 157.2 | 14 | 302 | 383 |
| OMP 200 | 194.5 | 14 | 360 | 310 |
| OMP 250 | 240.3 | 11 | 380 | 250 |
| OMP 315 | 314.5 | 9 | 375 | 192 |
| OMP 400 | 389.5 | 7 | 360 | 155 |
| OMP 500 | 486.5 | 6 | 385 | 120 |
These catalogue data apply to the listed 25 mm, 1 in, splined and 28.56 mm tapered shaft configurations. Other shaft arrangements require their corresponding table. Separate maximum limits must not be combined as one duty point.
OMP 125 lists 120.2 cm3/rev, 14 MPa continuous pressure differential, 236 Nm continuous torque and 490 rpm maximum continuous speed. OMP 160 lists 157.2 cm3/rev, 14 MPa, 302 Nm and 383 rpm. The comparison shows why displacement, pressure and speed must be read together.
Compare the required torque at the intended running speed with the selected model data. A larger displacement changes the flow needed for a target speed; it does not establish a proportional increase in continuous torque. The selected shaft version and the operating point still determine which catalogue data apply.
As a calculated example, assume 20 L/min reaches the OMP 125 with 120.2 cm3/rev displacement. Ideal motor speed is flow x 1000 / displacement, giving 20 x 1000 / 120.2 = approximately 166.4 rpm before volumetric losses. This is a flow estimate, not a measured BLINCE performance point or confirmation that the motor can deliver rated torque at that speed.
Actual speed and available torque depend on the operating point, oil conditions and motor losses. Use the relevant curve, starting data and inlet and outlet conditions to complete the selection. If the machine needs very low speed or changes load rapidly, include that duty explicitly in the enquiry.
| Item | Details for the enquiry |
|---|---|
| Shaft | OMP shaft profile diameter key or spline usable length and external loading |
| Mounting | Flange form pilot bolt pattern and available space |
| Oil ports | Connection type position and hose clearance from the approved drawing |
| Return and drain | Outlet pressure and the drain arrangement for the supplied motor |
| Duty point | Required starting torque running torque speed and available flow |
For a conveyor, brush or rotary assembly enquiry, state whether the motor connects directly or through a belt, sprocket or gearbox. Include the load on the output shaft and its position. These are machine-duty examples; the actual configuration must be reviewed for its own hydraulic and mechanical requirements.
The reviewed catalogue lists 36 cm3/rev for OMP 36. Use the geometric displacement for the matching configuration rather than assuming the model number is an exact displacement.
The table entries are limits or model-specific ratings, not a single performance point. Check the intended speed, pressure and load against the applicable operating curve and duty instructions.
Send the full existing reference and nameplate photograph, the shaft and mounting drawing, port details and the working duty. Include control or brake connections if they are part of the existing assembly.
Send BLINCE the complete OMP reference, quantity and installation drawing. Add the required starting torque, running speed, available flow and inlet and outlet pressures, together with the connection details that must be retained.
