Product Selection Guide
The FluiDyne V20 Series models compared here offer varying flow rates, displacements, shaft types, port orientations, and pressure ratings. All are direct Vickers replacements, fully SAE J744 compliant, and designed for easy interchangeability in hydraulic systems. Key differences lie in output (GPM and pressure), shaft configuration, rotation direction, and specialized covers such as flow control. See all single stage vane pumps for detailed comparisons.
?? 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 |
|---|---|---|---|---|
| WF820553 (Current, see Vickers replacements) | 11.5 GPM | 2500 PSI | 36.3 cm³/r (2.22 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820556 | 5.7 GPM | 2500 PSI | 18.0 cm³/r (1.10 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820552 | 8.4 GPM | 2500 PSI | 26.6 cm³/r (1.62 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820551 | 12.5 GPM | 2500 PSI | 39.5 cm³/r (2.41 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820559 | 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: Flow rates range from 5.7 GPM (WF820556) to 12.5 GPM (WF820551). Displacement varies from 18.0 cm³/r (WF820556) up to 39.5 cm³/r (WF820551).
Selection Guide: Select a model with a flow rate and displacement that matches your system’s actuator speed and volume requirements—see our full vane pump selection for specifications.—higher GPM/displacement for faster or larger cylinders.
Maximum Pressure
Difference: Most models are rated to 2500 PSI, except WF820551, which is rated at 2200 PSI in its description (but 2500 PSI in the summary).
Selection Guide: For systems requiring operation at or above 2500 PSI, verify the actual maximum rating—WF820553, WF820556, WF820552, and WF820559 are confirmed at 2500 PSI.
Shaft Type & Extension
Difference: Most models use a 3/4″ straight keyed shaft (varied extension), but WF820552 and WF820559 list 11-tooth splined shaft options.
Selection Guide: Choose splined shafts (WF820552, WF820559) for high-torque or vibration-prone environments; straight key for standard hydraulic coupling.
Port Configuration & Size
Difference: Inlet and outlet ports vary in thread type and orientation: some are NPT, others are BSPP. Port positions include inline (0°), opposite (180°), and 90° clockwise.
Selection Guide: Match port orientation to your plumbing layout: 90° (WF820553) for right-angle connections, inline (WF820556, WF820559) for straight-through piping, and 180° (WF820552, WF820551) for opposite-side connections.
Rotation Direction
Difference: WF820553, WF820556, WF820552 are right-hand (clockwise); WF820551 and WF820559 are left-hand (counter-clockwise).
Selection Guide: Select rotation direction to match your drive motor or system setup—incorrect rotation can damage the pump.
Specialized Features
Difference: WF820559 includes a flow control cover and built-in relief valve (6 GPM flow control, 2000 PSI relief).
Selection Guide: Choose WF820559 for applications needing integrated flow control and overpressure protection.
Maximum Speed
Difference: Max speed ranges from 2400 RPM (WF820551) to 3000 RPM (WF820556); others are 2500–2800 RPM.
Selection Guide: For high-speed drive applications, select a pump rated for the desired RPM.
Quick Selection Guide
If you need: Lowest flow for compact systems or precise control
Choose: WF820556 (5.7 GPM, 1.10 in³/r, 3000 RPM, right-hand)
Because: Ideal for smaller actuators or where fine flow control is needed; highest maximum speed.
If you need: Mid-range flow and displacement with splined shaft for higher torque
Choose: WF820552 (8.4 GPM, 1.62 in³/r, 2800 RPM, right-hand, splined shaft, 180° ports)
Because: Combines moderate output with robust shaft for demanding drives.
If you need: Standard flow and straightforward porting for typical right-hand systems
Choose: WF820553 (11.5 GPM, 2.22 in³/r, 2500 RPM, right-hand, 90° port orientation)
Because: Balances output and reliability; 90° port position helps in tight installations.
If you need: Highest flow and displacement for large actuators, left-hand rotation
Choose: WF820551 (12.5 GPM, 2.41 in³/r, 2400 RPM, left-hand, 180° ports)
Because: Best for high-demand, counter-clockwise systems; check pressure requirement.
If you need: Built-in flow control and relief valve for precise, protected operation
Choose: WF820559 (6.2 GPM, 1.19 in³/r, 2800 RPM, left-hand, inline ports)
Because: Integrated controls simplify circuit design and enhance safety.
Compatibility: All models are 100% interchangeable with Vickers V20 series and are part of our extensive hydraulic pumps lineup, follow SAE ‘A’ 2-bolt flange mounting, and use G1″/G1/2″ BSPP straight thread ports for easy swap-in.
