Product Selection Guide
These FluiDyne V20 Series single stage vane pumps share common SAE ‘A’ mounting, 2-bolt flange, and max pressure ratings, but differ in flow rate, displacement, shaft type/extension, rotation direction, port orientation, and connection sizes. Selecting the right model depends on your required flow, direction of rotation, preferred shaft style, and port configuration.
?? 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 |
|---|---|---|---|---|
| WF8203031 (Current) | 5.7 GPM | 2500 PSI | 18.0 cm³/r (1.10 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8203060 | 9.4 GPM | 2500 PSI | 29.7 cm³/r (1.81 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8203004 | 9.4 GPM | 2500 PSI | 29.7 cm³/r (1.81 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8203009 | 6.2 GPM | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8203013 | 10.4 GPM | 2500 PSI | 32.8 cm³/r (2.00 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Flow Rate & Displacement
Difference: WF8203031: 5.7 GPM (1.10 in³/r), WF8203009: 6.2 GPM (1.19 in³/r), WF8203060 & WF8203004: 9.4 GPM (1.81 in³/r), WF8203013: 10.4 GPM (2.00 in³/r)
Selection Guide: Select a higher GPM/displacement for larger actuators or faster operation; lower GPM for smaller circuits or precise control.
Rotation Direction
Difference: WF8203031 & WF8203013: Left-Hand (Counter-Clockwise); WF8203060, WF8203004, WF8203009: Right-Hand (Clockwise)
Selection Guide: Match rotation to your prime mover; incorrect rotation will cause pump failure.
Shaft Type & Extension
Difference: WF8203060: Splined shaft (1.25″ extension); others: Straight keyed shaft (1.75″ or 2.66″ extension)
Selection Guide: Choose splined shaft for high-torque, heavy-duty applications; straight keyed for standard use. Check extension length for equipment fit.
Port Orientation & Connection
Difference: WF8203031 & WF8203009 & WF8203013: Inline ports (0°); WF8203004: 90° CCW from inlet; WF8203060: 180° (opposite) from inlet
Selection Guide: Inline ports simplify straight plumbing; 90° or 180° options help in tight spaces or when side entry is required.
Port Size & Thread Type
Difference: Inlets vary from 1″ NPT (WF8203031, WF8203009) to 1-1/4″ NPT (WF8203060, WF8203004), and 1-5/8″-12 (WF8203013); outlets range from 3/4″ NPT to 1-1/16″-12 or G1/2″ BSPP
Selection Guide: Ensure port size and thread type match your system connections or adapters.
Max Speed
Difference: WF8203009: Up to 3400 RPM; WF8203031: 3000 RPM; WF8203060 & WF8203004: 2800 RPM; WF8203013: 2500 RPM
Selection Guide: If your system runs at higher speeds, choose a pump rated for that RPM.
Quick Selection Guide
If you need: Lowest flow for small actuators or precise circuits
Choose: WF8203031 (5.7 GPM, left-hand rotation)
Because: Smallest displacement with inline ports and keyed shaft, ideal for compact applications.
If you need: Slightly higher flow with right-hand rotation and inline ports
Choose: WF8203009 (6.2 GPM, right-hand rotation)
Because: Provides modest flow with inline porting and standard shaft extension.
If you need: Mid-range flow with high-torque shaft option
Choose: WF8203060 (9.4 GPM, splined shaft, right-hand rotation, 180° port position)
Because: Splined shaft suits higher torque, 9.4 GPM for mid-size cylinders, 180° porting for opposite plumbing.
If you need: Mid-range flow with alternative port orientation
Choose: WF8203004 (9.4 GPM, right-hand rotation, 90° CCW port position, straight shaft)
Because: Useful when side access to ports is needed in confined installs.
If you need: Maximum flow in this selection and left-hand rotation
Choose: WF8203013 (10.4 GPM, left-hand rotation, inline ports)
Because: Best for circuits requiring higher flow and left-hand drive, with largest displacement.
Compatibility: All models are direct Vickers replacements, fully interchangeable, and follow SAE J744 mounting for easy retrofitting. Standard G1″/G1/2″ BSPP ports simplify connection. 12-month warranty and same-day shipping available on in-stock items. Volume pricing starts at 4 units.
