Product Selection Guide
These Series 52/53 components can be compared primarily by displacement (flow per revolution) and maximum speed, since the listed nominal pressure is the same across the compared part numbers. If you’re comparing options across our broader hydraulic pumps selection, keep in mind that mounting and control configuration can be just as important as displacement.
?? 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 |
|---|---|---|---|---|
| R986111528 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110961 | 60cc | 3600 PSI | 2600 | 52 |
| R986111115 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110684 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986111054 | 74cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986111528 is a 100cc unit, matching R986111115 and R986110684 for similar flow output; R986111054 (74cc) and R986110961 (60cc) provide lower flow per revolution, which can be beneficial when downsizing flow or fitting a smaller displacement requirement. For more options in this design class, see our piston pumps category.
Pressure Rating
All listed comparison parts show a nominal pressure of 3600 PSI, matching R986111528; note that R986111528 also lists a 4600 PSI peak pressure, so confirm peak-pressure requirements when cross-referencing alternatives.
Speed
R986111528 is rated to 2300 max speed, aligning with the other 100cc options (R986111115 and R986110684); the 60cc (R986110961) and 74cc (R986111054) options list 2600 max speed, which may matter if your application requires higher allowable RPM.
Quick Selection Guide
Choose: R986111528
Because: When you need a Series 52/53 100cc unit rated for 3600 PSI nominal pressure, 4600 PSI peak pressure, and 2300 max speed.
Choose: R986111115 or R986110684
Because: When you need a 100cc, 3600 PSI nominal pressure, 2300 max speed alternative within the same Series 52/53 performance band.
Choose: R986111054 (74cc) or R986110961 (60cc)
Because: When you need lower displacement (reduced flow per revolution) and/or a higher listed max speed (2600) compared with the 100cc, 2300 max speed options.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm displacement, nominal/peak pressure, and maximum speed meet your system requirements. If you’re standardizing across fleets, it can also help to compare related R986111250 configurations for similar platform requirements.
