Product Selection Guide
Within the 52/53 series, R986111126 sits mid-range in displacement while matching the same nominal pressure rating as the compared options, so selection is primarily driven by required flow (cc) and allowable speed when comparing hydraulic pumps.
?? 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 |
|---|---|---|---|---|
| R986111126 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986111247 | 110cc | 3600 PSI | 2200 | 31* |

| R986110978 | 60cc | 3600 PSI | 2600 | 52 |
Key Differences
Displacement
R986111126 is 74cc; choose higher-displacement alternatives (110cc or 100cc) when you need more flow, or 60cc options when lower flow is sufficient and you want to stay closer to the lower end of displacement.
Pressure Rating
All listed comparison parts show 3600 PSI nominal pressure, matching R986111126; if your system relies on higher transient capability, note R986111126 also lists a 4600 PSI peak pressure.
Speed
R986111126 is rated to 2600 max speed, matching the 60cc options (2600) and exceeding the 100cc (2300) and 110cc (2200) alternatives, which may matter in higher-speed drive setups.
Quick Selection Guide
Choose: R986111126
Because: When you need a 74cc displacement unit with 3600 PSI nominal pressure and up to 2600 max speed (and a listed 4600 PSI peak pressure).
Choose: Higher displacement model
Because: When flow requirements exceed 74cc—consider R986111247 (110cc) or R986110676 (100cc) while confirming their lower max speeds (2200–2300) fit your operating range.
Choose: Lower displacement model
Because: When 74cc is more than needed—consider R986110689 or R986110978 (60cc), which maintain 3600 PSI nominal pressure and 2600 max speed.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation.
