Product Selection Guide
Within the Bosch Rexroth 31* series options shown, R986111319 stands out primarily by its higher displacement, while all compared models share the same nominal pressure rating and differ mainly in speed capability.
?? 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 |
|---|---|---|---|---|
| R986111319 | 110cc | 3600 PSI | 2200 | 31* |
| R986110069 | 60cc | 3600 PSI | 2600 | 52 |
| R986110071 | 28cc | 3600 PSI | 3000 | 52/53 |
| R986111475 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110581 | 74cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986111319 is 110cc versus 74cc (R986110581), 71cc (R986111475), 60cc (R986110069), and 28cc (R986110071); choose higher displacement when you need more flow per revolution, and lower displacement when you need less flow and potentially finer control at higher speeds.
Pressure Rating
All listed comparison parts show 3600 PSI pressure; R986111319 is rated 3600 PSI nominal with 4600 PSI peak, so confirm your system’s required nominal and peak pressures align with the component you select.
Speed
R986111319 is 2200 max speed, while the others listed are 2600 (R986110069, R986111475, R986110581) or 3000 (R986110071); if your duty cycle requires higher operating speed, select a model with a higher stated speed rating.
Quick Selection Guide
Choose: R986111319
Because: When you need 110cc displacement with 3600 PSI nominal and 4600 PSI peak capability, and your operating speed requirement is within 2200 max speed.
Choose: R986110581 or R986111475
Because: When you need a mid-range displacement (74cc or 71cc) with 3600 PSI rating and a higher listed speed capability (2600) than R986111319.
Choose: R986110071 or R986110069
Because: When you need lower displacement (28cc or 60cc) while maintaining 3600 PSI rating, and you require higher listed speed capability (3000 for R986110071 or 2600 for R986110069).
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. If you’re comparing alternatives across our hydraulic pumps lineup, match the interface details first—then confirm performance requirements.
