Product Selection Guide
These 31* components can be compared primarily by displacement (flow per revolution) and allowable speed, since the listed nominal pressure rating is the same across the options. If you’re comparing other hydraulic pumps for similar mobile equipment duty cycles, confirm your system type (open vs. closed loop) and required 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 |
|---|---|---|---|---|
| R986111013 | 110cc | 3600 PSI | 2200 | 31* |
| R986111453 | 140cc | 3600 PSI | 2000 | 31* |

| R986110061 | 74cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986111013 is 110cc; choose higher displacement (e.g., 140cc) when you need more flow per revolution, or lower displacement (100cc, 85cc, 74cc) when you need less flow per revolution and finer control at a given speed. For more options in this style, browse our piston pumps selection.
Pressure Rating
All compared models list 3600 PSI nominal pressure; match your system’s required pressure rating, and note that R986111013 additionally specifies a 4600 PSI peak pressure requirement that should be met by the replacement.
Speed
Maximum speed varies by model (R986111013: 2200; alternatives range from 2000 to 2600), so select a unit that meets or exceeds your operating speed requirements.
Quick Selection Guide
Choose: R986111013
Because: When you need 110cc displacement with 3600 PSI nominal pressure, 4600 PSI peak pressure capability, and up to 2200 max speed.
Choose: Higher displacement model
Because: When flow requirements exceed what a 110cc unit can provide at your available operating speed (e.g., consider R986111453 at 140cc, noting its listed max speed is 2000).
Choose: Lower pressure model
Because: When system operates at lower pressures for cost savings.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm the replacement meets both nominal and any required peak pressure and speed limits for your system.
