Product Selection Guide
The Fluidyne V20 Series models compared here are all direct Vickers replacements, including a wide range of single stage vane pumps,, sharing SAE ‘A’ 2-bolt flange mounting and high-pressure ratings, but differ significantly in flow rate, displacement, rotation, shaft type, port configuration, and maximum speed. See our vane pumps selection for additional configurations. Selecting the right model depends on your required flow, system direction, shaft compatibility, and plumbing layout.
?? 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 |
|---|---|---|---|---|
| WF820534 (Current) | 13.5 GPM | 2500 PSI | 42.6 cm³/r (2.60 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820531 | 6.2 GPM | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820537 | 6.2 GPM | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820535 | 11.5 GPM | 2500 PSI | 36.3 cm³/r (2.22 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8201811 | 13.5 GPM | 2500 PSI | 42.6 cm³/r (2.60 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Flow Rate & Displacement
Difference: Models range from 6.2 GPM (1.19 in³/rev) to 13.5 GPM (2.60 in³/rev) at 1200 RPM.
Selection Guide: Choose WF820531 for low-flow systems or pilot circuits; select WF820534 or WF8201811 for higher-demand systems needing 13+ GPM. The V201P13P39C11R – FluiDyne V20 Pump is another top-choice for similar flow and displacement requirements.
Rotation Direction
Difference: WF820531, WF820537, and WF820535 rotate right-hand (clockwise); WF820534 is left-hand (counter-clockwise); WF8201811 is right-hand.
Selection Guide: Match the pump’s rotation to your drive motor or existing setup. Use WF820534 only if you require left-hand rotation.
Shaft Type & Extension
Difference: WF820534 and WF820535 use a 9-tooth splined shaft (1.25″ extension); others use 3/4″ straight keyed shafts, generally with 1.75″ or 2.66″ extension.
Selection Guide: Select splined shafts like WF820534/WF820535 for high-torque or splined couplings; pick straight keyed shafts for standard couplings.
Port Size & Position
Difference: Most models have 1-1/4″ NPT inlet and 3/4″ NPT or 1-1/16″-12 straight thread outlet; WF820535 has 1-5/8″-12 straight thread inlet. Port positions vary: inline (0°), 90° (WF820537), or opposite (180°, WF820535).
Selection Guide: Choose inline ports for direct line connections, 90° for space constraints, or 180° if piping needs are opposite. For specialized systems, see our pumps with integral valves for added flexibility.
Maximum Pressure & Speed
Difference: All models except WF820534 and WF8201811 support up to 2500 PSI; those two are rated for up to 2200 PSI. Max speed ranges from 2400 to 3400 RPM.
Selection Guide: For applications above 2200 PSI, avoid WF820534/WF8201811. Select WF820531 if high-speed operation (up to 3400 RPM) is a priority.
Model Number Patterns
Difference: Higher numeric suffixes (e.g., WF820534/1811) indicate higher displacement and flow; rotation and special shaft or port configurations are marked by model code.
Selection Guide: Match the model code to your required flow, rotation, and shaft type—WF820531/537 for lower flow, WF820534/1811 for highest flow. For comparable right-hand rotation models, review the V201P13P3A11R – FluiDyne V20 Pump.
Quick Selection Guide
If you need: Lowest flow for pilot or auxiliary circuits (6.2 GPM, 1.19 in³/rev)
Choose: WF820531
Because: It offers the lowest displacement and highest max speed (3400 RPM), ideal for precise or high-speed small circuits.
If you need: Moderate flow with 90° port orientation (space constraints)
Choose: WF820537
Because: It provides 7 GPM, right-hand rotation, and a 90° port, simplifying plumbing in tight installations.
If you need: Mid-to-high flow with highest pressure (up to 2500 PSI)
Choose: WF820535
Because: It delivers 11.5 GPM at 2500 PSI with a splined shaft for high-torque needs.
If you need: Highest flow (13.5 GPM, 2.60 in³/rev), left-hand rotation, and splined shaft
Choose: WF820534
Because: This is the only model with left-hand rotation and high flow, ideal for applications requiring counter-clockwise operation.
If you need: Highest flow (13.5 GPM) with right-hand rotation and special shaft
Choose: WF8201811
Because: It matches the top flow rate and offers a unique shaft, useful for custom drive requirements.
Compatibility: All models feature SAE J744 ‘A’ 2-bolt flange mounting and G1″/G1/2″ BSPP ports for direct Vickers pump interchangeability—see our full line of Vickers replacement pumps applications for further compatibility.
