Product Selection Guide
These Series 52/53 components share the same nominal pressure and max speed ratings, so selection primarily comes down to displacement (flow) requirements and fitment details for the replacement. If you’re comparing options across our hydraulic pumps lineup, focus first on displacement and control style, then verify mounting and porting.
?? 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 |
|---|---|---|---|---|
| R986110632 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986111328 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110118 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110104 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110106 | 71cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110632 is 74cc, compared with 71cc options (R986110104, R986110106) and 45cc options (R986111328, R986110118); higher displacement supports higher flow demand at the same speed, while lower displacement is better suited when less flow is required.
Pressure Rating
All listed comparison parts show 3600 PSI nominal pressure; R986110632 additionally lists a 4600 PSI peak pressure—confirm your system’s required peak capability and ensure the replacement meets or exceeds it.
Speed
All listed parts show a max speed of 2600, so speed is not a primary differentiator among these options.
Quick Selection Guide
Choose: R986110632
Because: When you need 74cc displacement with 3600 PSI nominal pressure, 4600 PSI peak pressure capability, and 2600 max speed to match the current unit’s performance requirements.
Choose: Higher displacement model
Because: When your required flow rate is higher than what a 74cc displacement unit can provide at your available operating speed.
Choose: Lower pressure model
Because: When the hydraulic system operates at lower pressures and the replacement component’s pressure rating still meets the system requirements.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. For additional options in this family of piston pumps, our team can help cross-reference by displacement, control type, and OEM number.
