Product Selection Guide
These FluiDyne V20 Series hydraulic vane pumps are all direct Vickers replacements with identical SAE ‘A’ 2-bolt flange mounting and 2500 PSI max pressure, but differ mainly in flow rate, displacement, shaft type/size, rotation direction, port orientation, and maximum speed. Selecting the right model depends on your system’s required flow, shaft compatibility, rotation, and installation constraints.
?? 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 |
|---|---|---|---|---|
| WF8201365 (Current) | 11.5 GPM | 2500 PSI | 36.3 cm³/r (2.22 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8201321 | 5.7 GPM | 2500 PSI | 18.0 cm³/r (1.10 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820135 | 6.2 GPM | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8201371 | 6.2 GPM | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8201358 | 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: WF8201365 delivers 11.5 GPM at 2.22 in³/rev, while other models range from 5.7 GPM (1.10 in³/rev, WF8201321) to 7 GPM (1.39 in³/rev, WF8201358) and 6.2 GPM (1.19 in³/rev, WF820135 & WF8201371).
Selection Guide: Choose WF8201365 for higher flow needs (11.5 GPM). Select WF8201321, WF820135, WF8201371, or WF8201358 for lower flow or smaller displacement applications.
Shaft Type & Size
Difference: WF8201365 uses an 11-tooth splined shaft (2.94″ ext). WF8201321, WF820135, and WF8201371 use 3/4″ straight shafts with key (varied extension). WF8201371 also lists a 7/8″ threaded shaft with Woodruff key. WF8201358 uses a 9-tooth splined shaft (1.25″ ext).
Selection Guide: Select splined shafts (WF8201365 or WF8201358) for higher torque or splined couplings. Choose straight keyed shafts for standard coupling compatibility. Threaded shafts (WF8201371) suit unique coupling requirements.
Rotation Direction
Difference: WF8201365, WF820135, WF8201371, and WF8201358 are right-hand (clockwise); WF8201321 is left-hand (counter-clockwise).
Selection Guide: Ensure pump rotation matches your system. Use WF8201321 for counter-clockwise, others for clockwise systems.
Port Orientation & Position
Difference: WF8201365, WF8201321, and WF820135 have ports opposite the inlet (180°); WF8201371 has ports at 90° clockwise from inlet; WF8201358 has ports inline with inlet (0°).
Selection Guide: Choose port orientation matching your plumbing layout: inline for straight-through connections (WF8201358), 90° for tight corners (WF8201371), or 180° for standard setups.
Maximum Speed
Difference: WF820135 supports up to 3400 RPM, WF8201321 and WF8201358 up to 3000 RPM, WF8201365 up to 2500 RPM.
Selection Guide: Select models with higher max speed ratings (WF820135) for high-RPM systems.
Quick Selection Guide
If you need: High flow rate (11+ GPM) and high displacement
Choose: WF8201365
Because: It provides 11.5 GPM at 2.22 in³/rev, ideal for larger actuators or faster cycle times.
If you need: Low flow rate and left-hand (counter-clockwise) rotation
Choose: WF8201321
Because: It delivers 5.7 GPM at 1.10 in³/rev with left-hand rotation for systems requiring reverse direction.
If you need: Standard flow with right-hand rotation and high RPM capability
Choose: WF820135
Because: Supports 6.2 GPM, 1.19 in³/rev, right-hand rotation, and up to 3400 RPM.
If you need: Right-hand rotation with 90° port orientation
Choose: WF8201371
Because: 6.2 GPM, 1.19 in³/rev, and ports oriented 90° for tight spaces or specific piping needs.
If you need: Splined shaft compatibility and inline porting
Choose: WF8201358
Because: 7 GPM, 1.39 in³/rev, 9-tooth splined shaft for high torque, and inline (0°) ports for straight connections.
Compatibility: All models are direct Vickers replacements, 100% interchangeable, SAE J744 ‘A’ 2-bolt flange mounting, and use G1″/G1/2″ BSPP straight thread ports for seamless system integration.
