Product Selection Guide
These hydraulic pumps from the FluiDyne V20 Series are all direct Vickers replacements, designed for easy interchangeability in systems using SAE ‘A’ 2-bolt mounting. The main differences are flow rate, displacement, shaft configuration, rotation direction, and port types. For a complete range of single stage vane pumps, see our category overview. Selecting the right model depends on your required flow, available speed, port compatibility, shaft/coupling requirements, and rotation direction for your system. To explore all vane pumps and their specifications, visit our dedicated section.
?? Important: The specifications shown are for reference and comparison purposes. Always verify specifications with the official manufacturer documentation or contact our technical team at (800) 823-4937 before ordering to ensure compatibility with your application. We cannot accept returns due to specification mismatches.
| Model Number | Flow Rate | Max Pressure | Displacement | Mounting |
|---|---|---|---|---|
| WF8201639 (Current) | 5.7 GPM | 2500 PSI | 18.0 cm³/r (1.10 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820169 | 13.5 GPM | 2500 PSI | 42.6 cm³/r (2.60 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8201695 | 13.5 GPM | 2500 PSI | 42.6 cm³/r (2.60 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8201611 | 6.2 GPM | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820168 | 6.2 GPM | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Flow Rate & Displacement
Difference: WF8201639 delivers 5.7 GPM (1.10 in³/r), WF8201611 and WF820168 deliver 6.2 GPM (1.19 in³/r), while WF820169 and WF8201695 provide 13.5 GPM (2.60 in³/r) at 1200 RPM.
Selection Guide: Choose WF820169 or WF8201695 for higher-output circuits needing 13.5 GPM. For lower flows, WF8201611, WF820168, or WF8201639 are suitable.
Rotation Direction
Difference: WF8201639, WF8201611, WF820168, and WF820169 are right-hand (clockwise). WF8201695 is left-hand (counter-clockwise).
Selection Guide: Match pump rotation to your drive shaft direction. Use WF8201695 for systems requiring left-hand (CCW) rotation.
Shaft Configuration
Difference: WF8201639, WF8201611, WF820168 have 3/4″ straight keyed shafts; WF820169/1695 feature 11-tooth splined shafts (with 2.94″ or 1.25″ extensions).
Selection Guide: Select splined shafts for higher torque or when using splined couplings. Use straight keyed shafts for standard couplings.
Port Type & Size
Difference: WF8201639 and WF8201611 have 1-1/4″ NPT inlet and 3/4″ NPT outlet; WF820169, WF8201695, and WF820168 use 1-1/4″ NPT inlet and 1-1/16″-12 straight thread outlet.
Selection Guide: Ensure port type matches your system plumbing. Use straight thread ports (WF820169, WF8201695, WF820168) for leak-resistant, high-pressure fittings.
Speed Ratings
Difference: WF8201611 and WF820168 allow up to 3400 RPM max speed, while others are rated to 2400–3000 RPM.
Selection Guide: For higher-speed drives, choose WF8201611 or WF820168.
Quick Selection Guide
If you need: High flow rate (13.5 GPM) at 1200 RPM
Choose: WF820169 (right-hand) or WF8201695 (left-hand)
Because: These models provide nearly 2.5× the output of others, ideal for larger actuators or parallel circuits.
If you need: Standard flow (6.2 GPM) with higher speed capability
Choose: WF8201611 or WF820168
Because: Both are rated to 3400 RPM max, suited for variable speed drives.
If you need: Compact low-flow application and standard shaft coupling
Choose: WF8201639
Because: Offers 5.7 GPM with a 3/4″ keyed shaft for simple installations.
If you need: Splined shaft for high-torque or specialty couplings
Choose: WF820169, WF8201695, or WF820168
Because: These models have 11-tooth splined shafts, preferred in demanding or OEM applications.
Compatibility: All models are 100% Vickers interchangeable, follow SAE J744 mounting, and use SAE ‘A’ 2-bolt flanges with G1″/G1/2″ BSPP ports for easy retrofit or replacement in existing systems. See our full lineup of Vickers replacement pumps for more options.
