Product Selection Guide
These Series 52/53 units share the same 3600 PSI nominal pressure class, so selection typically comes down to matching displacement (flow) and allowable speed to your existing setup. If you’re comparing options across our broader hydraulic pumps lineup, confirm the circuit type and control configuration first.
?? 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 |
|---|---|---|---|---|
| R986110051 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986111281 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110085 | 140cc | 3600 PSI | 2000 | 31* |
| R986111529 | 163cc | 3600 PSI | N/A | 52/53 |
| R986110038 | 71cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110051 is 74cc; comparable options range from 71cc (R986110038) up to 163cc (R986111529). Choose lower displacement when your required flow matches and you want closer replacement sizing; choose higher displacement when your system needs more flow per revolution.
Pressure Rating
All listed comparison models are rated at 3600 PSI nominal pressure; R986110051 also specifies a 4600 PSI peak rating, so confirm your system peak-pressure requirement against the exact part you’re replacing.
Speed
Maximum speed varies by model: R986110051 and R986110038 are listed at 2600, while higher-displacement options list lower speeds (2300 for R986111281 and 2000 for R986110085); select a model that meets or exceeds your operating speed. (R986111529 speed is not provided.)
Quick Selection Guide
Choose: R986110051
Because: When you need a 74cc displacement unit with 3600 PSI nominal pressure, 4600 PSI peak pressure, and up to 2600 max speed in a Series 52/53 replacement.
Choose: Higher displacement model
Because: When your required displacement (flow per revolution) is higher than 74cc—e.g., 100cc (R986111281), 140cc (R986110085), or 163cc (R986111529)—and your operating speed aligns with the model’s listed limit.
Choose: Lower pressure model
Because: Not applicable here: all listed comparison models show 3600 PSI nominal pressure, so select based on displacement and speed rather than a lower pressure rating.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. If you’re sourcing other axial piston pumps, use the same verification steps to avoid fitment and performance issues.
