Product Selection Guide
The Fluidyne V20 Series models compared here are all direct Vickers replacements, sharing standard SAE ‘A’ 2-bolt mounting and similar port sizes for easy interchangeability. For similar displacement options, see V201P5P18C11R – FluiDyne V20 Pump. Key differences are found in flow rate, displacement, shaft type, rotation direction, and port orientation. These factors directly impact pump compatibility with your hydraulic system, optimum performance, and installation convenience.
?? 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 |
|---|---|---|---|---|
| WF820537 (Current) | 6.2 GPM | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820534 | 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) |
| 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: Flow rates range from 6.2 GPM (1.19 in³/rev) to 13.5 GPM (2.60 in³/rev) at 1200 RPM depending on model.
Selection Guide: Choose lower displacement/flow models (WF820531, WF820537) for precise, lower flow applications. Opt for higher displacement/flow models (WF820534, WF8201811) for large actuators or higher speed circuits.
Maximum Pressure & Speed
Difference: Most models are rated to 2500 PSI; WF820534 and WF8201811 are limited to 2200 PSI and 2400 RPM max speed, while others handle up to 2500 PSI and higher speeds.
Selection Guide: For demanding high-pressure or high-speed applications, prefer WF820531 or WF820537. For standard pressure and moderate speed, WF820534 and WF8201811 are suitable.
Shaft Type & Extension
Difference: Shaft options include 3/4″ straight keyed (standard, 1.75″ or 2.66″ extension) and splined (9-tooth, 1.25″ extension) on some models.
Selection Guide: Choose splined shafts (WF820534, WF820535) for high-torque or heavy-duty couplings. Straight keyed shafts (WF820531, WF820537, WF8201811) are ideal for standard applications or where existing drive couplings are keyed.
Rotation Direction
Difference: WF820534 is Left-Hand (CCW); others are Right-Hand (CW).
Selection Guide: Ensure the model matches your drive rotation: use left-hand models for CCW drives and right-hand for CW. Incorrect rotation can damage the pump.
Port Position
Difference: Varies by model: inline with inlet (0°), 90° clockwise, or opposite inlet (180°).
Selection Guide: Select port orientation to best fit your plumbing layout: 90° positions (WF820537) for space constraints or unique plumbing requirements; inline (WF820531, WF820534, WF8201811) for straightforward hose routing.
Quick Selection Guide
If you need: A compact pump with lower flow for precise control
Choose: WF820531 or WF820537
Because: Both provide 6.2 GPM at 1200 RPM with standard pressure and keyed shaft, ideal for smaller actuators or compact circuits.
If you need: Higher flow for larger cylinders or rapid cycle times
Choose: WF820534 or WF8201811
Because: These models deliver up to 13.5 GPM at 1200 RPM, supporting more demanding applications.
If you need: A specific shaft configuration for high-torque or special couplings
Choose: WF820534 or WF820535
Because: Offer 9-tooth splined shafts, suitable for demanding or OEM-specific drive requirements.
If you need: Left-hand (counter-clockwise) rotation
Choose: WF820534
Because: It is the only left-hand model in this group, matching CCW drive systems.
If you need: Unique port positions for challenging installations
Choose: WF820537 (90° clockwise) or WF820535 (180° opposite inlet)
Because: These options simplify hose routing in tight or unusual layouts.
Compatibility: All models are 100% interchangeable with Vickers V20 series, share SAE J744 ‘A’ 2-bolt mounting, and feature G1″/G1/2″ BSPP straight thread ports for straightforward drop-in replacement. Our Vickers replacement pumps applications portfolio demonstrates proven field reliability.
