Product Selection Guide
These Series 52/53 components share a 3600 PSI nominal pressure rating, with primary selection differences driven by displacement (flow capacity) and maximum speed limits across models.
?? 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 |
|---|---|---|---|---|
| R986110970 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110674 | 63cc | 3600 PSI | 2600 | 53 |
| R986110679 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986111098 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110680 | 100cc | 3600 PSI | 2300 | 52/53 |
Key Differences
Displacement
R986110970 is 45cc for lower flow needs, while the comparison options increase displacement to 63cc (R986110674), 71cc (R986111098), or 100cc (R986110679/R986110680) when higher flow is required at similar nominal pressure.
Pressure Rating
All listed comparison products are rated at 3600 PSI nominal; R986110970 additionally lists a 4600 PSI peak pressure, so confirm your system’s peak/relief settings align with the part you select.
Speed
Maximum speed is 2600 for R986110970 and for the 63cc/71cc options, while the 100cc options list 2300, which can matter if your drive speed is near the upper limit.
Quick Selection Guide
Choose: R986110970
Because: When you need a 45cc 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 flow exceeds what a 45cc unit can provide—consider 63cc (R986110674), 71cc (R986111098), or 100cc (R986110679/R986110680) while maintaining a 3600 PSI nominal rating.
Choose: Lower pressure model
Because: When the system operates at lower pressures than 3600 PSI nominal and a lower-rated option is acceptable; select only after confirming your required nominal and peak pressure limits.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation.
