Product Selection Guide
These 52/53 series options are best compared by matching displacement and pressure first, then using speed capability to confirm suitability for your operating RPM range.
?? 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 |
|---|---|---|---|---|
| R986111280 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110127 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986111092 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986111070 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110672 | 60cc | 3600 PSI | 2600 | 52 |
Key Differences
Displacement
R986111280, R986110127, and R986111092 are 100cc options for matching the same flow per revolution, while R986111070 (45cc) and R986110672 (60cc) reduce flow per revolution and may be better where lower flow is required.
Pressure Rating
All listed comparison parts show 3600 PSI nominal pressure; R986111280 additionally specifies a 4600 PSI peak rating, so confirm your system’s peak/transient pressure requirements against the exact part’s ratings.
Speed
R986111280, R986110127, and R986111092 list 2300 max speed, while R986111070 and R986110672 list 2600; choose based on whether your application requires the higher speed capability.
Quick Selection Guide
Choose: R986111280
Because: When you need a 52/53 series 100cc unit with 3600 PSI nominal pressure, 4600 PSI peak pressure capability, and 2300 max speed.
Choose: R986110127 or R986111092
Because: When you need the same 100cc displacement, 3600 PSI pressure rating, and 2300 speed rating as the current unit and are matching those core specs.
Choose: R986111070 (45cc) or R986110672 (60cc)
Because: When you need lower displacement (reduced flow per revolution) and/or require the higher listed 2600 speed rating compared with the 2300-rated 100cc options.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. If you’re comparing options across our piston pumps lineup, also confirm control type and intended circuit (open vs. closed loop).
