Product Selection Guide
These FluiDyne V20 Series single stage vane pumps deliver consistent displacement and pressure but differ in shaft configuration, port orientation, flow rate, rotation direction, and connection types. These differences impact how easily each pump integrates into specific hydraulic circuits and equipment.
?? Important: The specifications shown are for reference and comparison purposes. For more details, see our Vickers replacement pumps resource. 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 |
|---|---|---|---|---|
| WF820608 (Current) | 6.2 GPM | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820602 | 6.2 GPM | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820603 | 6.2 GPM | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820604 | 6.2 GPM | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820600 | 11.5 GPM | 2500 PSI | 36.3 cm³/r (2.22 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Shaft Type and Extension
Difference: WF820608 has an 11-tooth splined shaft (1.25″ extension); WF820602 features a 3/4″ straight keyed shaft (2.66″ extension); WF820603 and WF820604 use a 9-tooth splined shaft (1.25″ extension); WF820600 has a 3/4″ straight keyed shaft (1.75″ extension).
Selection Guide: Select a splined shaft (WF820608, WF820603, WF820604) for higher torque or where precise alignment is critical. Choose a straight keyed shaft (WF820602, WF820600) for standard coupling or when replacement matching existing hardware.
Port Position
Difference: WF820608 and WF820604 have ports inline with inlet (0°); WF820602 and WF820603 have outlet ports opposite from inlet (180°).
Selection Guide: Inline port orientation (0°) simplifies straight-through plumbing; 180° port orientation suits installations where space requires ports on opposite sides.
Flow Rate & Displacement
Difference: WF820600 offers a higher flow/displacement (11.5 GPM, 36.3 cm³/r, 2.22 in³/r) compared to the others at 6.2–7 GPM (19.5–22.8 cm³/r, 1.19–1.39 in³/r).
Selection Guide: Choose WF820600 for systems demanding higher flow rates, such as large cylinders or multiple actuators. Select other models (WF820608, WF820602, WF820603, WF820604) for moderate flow needs or smaller hydraulic systems.
Rotation Direction
Difference: WF820600 is Left-Hand (Counter-Clockwise); all other models are Right-Hand (Clockwise).
Selection Guide: Match pump rotation to your prime mover’s direction—select WF820600 for left-hand drive, others for right-hand.
Port Connection Type & Size
Difference: WF820608 and WF820600 use NPT for inlet/outlet; others use BSPP threads. Inlet sizes vary (1-1/4″ NPT, 1-5/8″-12, G1″ BSPP).
Selection Guide: Select NPT-threaded models (WF820608, WF820600) for North American standards or existing NPT plumbing; BSPP-threaded models (WF820602, WF820603, WF820604) for metric or European plumbing.
Quick Selection Guide
If you need: High flow and large displacement for demanding hydraulic systems
Choose: WF820600
Because: It delivers 11.5 GPM at 1200 RPM and 2.22 in³/r displacement, suitable for larger actuators or multi-function circuits.
If you need: Splined shaft for high torque or specific coupling requirements
Choose: WF820608, WF820603, or WF820604
Because: These models offer splined shafts (11- or 9-tooth), ideal for high-torque or backlash-sensitive applications.
If you need: Straight keyed shaft for standard couplings and longer shaft extension
Choose: WF820602
Because: It features a 3/4″ straight keyed shaft with a 2.66″ extension, making it compatible with many common drive arrangements.
If you need: Specific port orientation for confined installation
Choose: WF820602 or WF820603 for 180° port orientation; WF820608 or WF820604 for inline 0° orientation
Because: This allows you to match plumbing layout to your equipment’s space constraints.
If you need: Left-hand (counter-clockwise) rotation
Choose: WF820600
Because: It is the only model in this group with left-hand rotation.
