Product Selection Guide
These Series 52/53 components are best compared by matching displacement for flow needs while confirming pressure and speed ratings align with your system requirements. If you’re evaluating alternatives across hydraulic pumps, focus on matching the full operating envelope and control configuration.
?? Important: The specifications shown are for reference and comparison purposes. Always verify specifications with the official manufacturer documentation or contact our technical team before ordering to ensure compatibility with your application.
| Part Number | Displacement | Pressure | Max Speed | Series |
|---|---|---|---|---|
| R986110804 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986111536 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110576 | 60cc | 3600 PSI | 2600 | 52 |
| R986110632 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986110941 | 63cc | 3600 PSI | 2600 | 53 |
Key Differences
Displacement
R986110804 and R986110632 match at 74cc; R986111536 increases to 100cc for higher flow per revolution, while R986110576 (60cc) and R986110941 (63cc) reduce displacement for lower flow demand or finer control at a given speed.
Pressure Rating
All listed comparison models show 3600 PSI nominal pressure; select based on displacement and speed needs while ensuring your system does not exceed the pressure rating requirements for the component.
Speed
Most options list 2600 max speed (R986110804, R986110576, R986110632, R986110941), while the higher displacement R986111536 lists 2300, which may matter if your application requires higher operating speed.
Quick Selection Guide
Choose: R986110804
Because: When you need a 74cc displacement in Series 52/53 with 3600 PSI nominal pressure, 4600 PSI peak pressure, and 2600 max speed to match the existing performance envelope.
Choose: Higher displacement model
Because: Choose R986111536 (100cc) when you need more displacement than 74cc to meet higher flow requirements, and your operating speed can accommodate its 2300 max speed.
Choose: Lower displacement model
Because: Choose R986110576 (60cc) or R986110941 (63cc) when your flow requirement is lower than 74cc while maintaining the listed 3600 PSI nominal pressure and 2600 max speed.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm displacement, pressure, and speed ratings align with your system requirements. For additional options in this product family, browse our piston pumps selection.
