Product Selection Guide
These FluiDyne V20 Series single stage vane pumps differ primarily in flow rate, displacement, pressure rating, shaft configuration, rotation direction, port orientation, and maximum speed. All models maintain SAE ‘A’ 2-bolt flange mounting and BSPP straight thread ports, ensuring direct Vickers replacement and easy interchangeability.
?? Important: The specifications shown are for reference and comparison purposes. For additional technical resources and installation guides, see our vane pumps documentation. 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 |
|---|---|---|---|---|
| WF820672 (Current) | 10.4 GPM | 2500 PSI | 32.8 cm³/r (2.00 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820675 | 9.4 GPM | 2500 PSI | 29.7 cm³/r (1.81 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820673 | 10.4 GPM | 2500 PSI | 32.8 cm³/r (2.00 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820678 | 11.5 GPM | 2500 PSI | 36.3 cm³/r (2.22 in³/r) | 2-Bolt Flange (SAE “A” size) |

Key Differences
Flow Rate
Difference: Flow rates range from 9.4 GPM (WF820675) to 13.5 GPM (WF820679) at 1200 RPM.
Selection Guide: Select WF820679 for applications needing the highest flow (up to 13.5 GPM); choose WF820675 for lower flow needs.
Displacement
Difference: Displacement varies from 29.7 cm³/r (1.81 in³/r, WF820675) to 42.6 cm³/r (2.60 in³/r, WF820679).
Selection Guide: Higher displacement models deliver more fluid per revolution and suit larger actuators or higher volume circuits.
Maximum Pressure
Difference: WF820679 is rated to 2200 PSI, while all other models are rated to 2500 PSI.
Selection Guide: For applications requiring up to 2500 PSI, avoid WF820679; use other models for higher pressure circuits.
Rotation Direction
Difference: WF820673 offers left-hand (counter-clockwise) rotation; all other models are right-hand (clockwise).
Selection Guide: Match rotation to your drive system—use WF820673 for counter-clockwise systems only.
Shaft Configuration
Difference: WF820672 and WF820673 use a 9-tooth splined shaft; WF820675 uses a 7/8″ threaded shaft with Woodruff key; WF820678 and WF820679 use special shaft configurations (Code 18).
Selection Guide: Choose shaft type based on coupling method and torque requirements—splined for high torque, threaded/keyed for standard coupling.
Port Position
Difference: WF820675 has outlet port opposite inlet (180°); other models have inline ports (0°).
Selection Guide: Select 180° port position (WF820675) for installations requiring ports on opposite sides.
Maximum Speed
Difference: WF820675 allows up to 2800 RPM; WF820679 up to 2400 RPM; others up to 2500 RPM.
Selection Guide: If higher RPMs are needed, WF820675 supports the highest maximum speed.

Quick Selection Guide
If you need: Lowest flow and displacement (compact circuits, smaller actuators)
Choose: WF820675
Because: Offers 9.4 GPM, 29.7 cm³/r displacement, and highest speed capability (2800 RPM).
If you need: Standard flow with right-hand rotation and inline ports
Choose: WF820672
Because: Provides 10.4 GPM, 32.8 cm³/r displacement, and 2500 PSI rating with easy inline plumbing.
If you need: Standard flow with left-hand rotation
Choose: WF820673
Because: Only model with left-hand (counter-clockwise) rotation for matching specific drive requirements.
If you need: Maximum flow for high-volume circuits
Choose: WF820679
Because: Delivers up to 13.5 GPM and 42.6 cm³/r displacement, ideal for large actuators or quick cycle times (note: max pressure 2200 PSI).
If you need: Slightly higher flow than standard but maintain max pressure
Choose: WF820678
Because: Offers 11.5 GPM at 2500 PSI, a balance between flow and pressure.
Compatibility: All models comply with SAE J744 mounting, are direct Vickers replacements, and feature G1″/G1/2″ BSPP straight thread ports for straightforward interchangeability in existing systems.
