Product Selection Guide
The provided FluiDyne V2020P double vane pump models differ primarily in their total flow rates, individual pump flows, port orientations, rotation direction, and maximum operating speeds. These differences are key when matching a pump to your hydraulic system requirements, especially where flow, speed, or specific porting is critical.
?? 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 specifications applications before ordering or review our vane pumps technical guides to ensure compatibility with your application. We cannot accept returns due to specification mismatches.
| Model Number | Flow Rate | Max Pressure | Displacement | Mounting |
|---|---|---|---|---|
| WF825666 (Current) | 8 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825663 | 6 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825699 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825601 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825865 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Total Flow Rate
Difference: WF825666 delivers a total of 9.0 GPM; WF825663 provides 12.0 GPM; WF825699 and WF825601 each deliver 17.0 GPM; WF825865 offers the highest at 19.0 GPM.
Selection Guide: Select higher total GPM models (WF825699, WF825601, WF825865) for systems with larger hydraulic demands or multiple actuators. Choose WF825666 or WF825663 for lower flow applications or where precise low-speed control is needed.
Individual Pump Flows
Difference: WF825666: Front 8 GPM / Rear 1 GPM; WF825663: Front 6 GPM / Rear 6 GPM; WF825699 & WF825601: Front 11 GPM / Rear 6 GPM; WF825865: Front 11 GPM / Rear 8 GPM.
Selection Guide: Match front/rear pump flows to your circuit’s flow-splitting needs. For example, WF825663 is ideal for equally split dual circuits; WF825865 suits applications needing more flow from the secondary section.
Maximum Speed
Difference: WF825666 limited to 1800 RPM (rear pump); WF825663 up to 3400 RPM; WF825699, WF825601, WF825865 all up to 2500 RPM (limited by front pump).
Selection Guide: Choose WF825663 for high-speed drive applications. WF825666 is best for systems with lower speed primemovers.
Rotation
Difference: WF825666 and WF825663 are left-hand (counter-clockwise); WF825699, WF825601, and WF825865 are right-hand (clockwise).
Selection Guide: Select rotation to match your prime mover. Verify your system’s direction to avoid installation issues.
Port Orientation
Difference: WF825666 & WF825865: front port 90° CCW, rear 90° CW; WF825663, WF825699, WF825601: both outlets 90° (CW or CCW).
Selection Guide: Choose based on your plumbing layout: split orientations (WF825666, WF825865) help in complex manifolds, while matching orientations (WF825663, WF825699, WF825601) ease parallel connections.
Shaft Type
Difference: WF825666, WF825663, and WF825865 list 13-tooth splined or straight keyed shafts; WF825601 uses shaft code 51 (not further detailed but likely keyed). For similar specifications, see V201P5P18C11R – FluiDyne V20 Pump.
Selection Guide: Splined shafts (WF825666, WF825663) are best for high-torque or shock-load applications; straight keyed shafts suit standard couplings.
Quick Selection Guide
If you need: The lowest combined flow for precise control
Choose: WF825666
Because: It offers 8 GPM (front) and 1 GPM (rear), ideal for low-flow, fine-control applications or pilot circuits.
If you need: Equal flow split for two circuits
Choose: WF825663
Because: Both sections provide 6 GPM, simplifying dual circuit designs.
If you need: High front section flow with moderate rear flow
Choose: WF825699 or WF825601
Because: Both deliver 11 GPM (front) and 6 GPM (rear), supporting larger actuators up front.
If you need: Maximum total flow and higher rear section flow
Choose: WF825865
Because: It provides 11 GPM (front) and 8 GPM (rear), maximizing output for high-demand dual circuits.
If you need: High drive speed capability
Choose: WF825663
Because: Rated to 3400 RPM, suitable for fast prime movers.
Compatibility: All models are direct Vickers replacements, 100% interchangeable, and use SAE ‘A’ 2-bolt flanges with G1″/G1/2″ BSPP ports for seamless installation. For single-circuit designs, see our single stage vane pumps options.
