Product Selection Guide
These FluiDyne V2020 double vane pumps are all direct Vickers replacements, sharing the same SAE ‘B’ 4-bolt flange mounting and porting, but they differ primarily in total flow output, pump section flow splits, rotation direction, port orientation, shaft type, and maximum speed. Selecting the right model depends on your system’s required flow (GPM), rotation, and configuration for inlet/outlet connections.
?? 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 |
|---|---|---|---|---|
| WF825654 (Current) | 7 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825659 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825657 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825651 | 8 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825975 | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Total Flow Output
Difference: WF825657 provides the highest total flow at 18.0 GPM, while WF825975 offers the lowest at 10.0 GPM. WF825654 and WF825651 both offer 14.0 GPM, and WF825659 delivers 12.0 GPM.
Selection Guide: Select WF825657 for applications needing maximum combined flow; WF825975 suits lower-flow systems.
Front vs Rear Pump Flow Split
Difference: WF825654 and WF825651 have balanced front/rear flows (7+7 GPM, 8+6 GPM), while WF825657 is more front-heavy (11+7 GPM) and WF825659/975 are highly unbalanced (e.g., 11+1 GPM, 10+0 GPM).
Selection Guide: Choose balanced models for circuits needing similar parallel flows; unbalanced for Hi-Lo circuits or single main flows with secondary functions.
Maximum Speed Capability
Difference: WF825654, as well as WF825657, allow up to 3000 and 2500 RPM respectively, suitable for higher-speed drives. WF825975 and WF825659 are limited to 1800 RPM.
Selection Guide: For high-speed motors, select WF825654 or WF825657; for slower drives, WF825975 or WF825659 are sufficient.
Rotation Direction
Difference: WF825654, WF825657, and WF825975 are left-hand (counter-clockwise); WF825659 and WF825651 are right-hand (clockwise).
Selection Guide: Match rotation to your prime mover. Select left-hand models for counter-clockwise drives, right-hand for clockwise.
Port Orientation
Difference: WF825654, WF825657, and WF825651 have both outlets inline with the inlet (0°), WF825659 is 90° CCW from inlet, and WF825975 is 180° (opposite) from inlet.
Selection Guide: Inline port models suit direct, in-line plumbing; 90° or 180° orientations help in restricted or custom layouts.
Shaft Type
Difference: WF825654 and WF825975 feature a 13-tooth splined shaft, while others use a straight keyed shaft.
Selection Guide: Choose splined shafts for higher torque or flexible couplings; straight keyed shafts for standard, lower-torque setups.
Quick Selection Guide
If you need: Highest total flow (18.0 GPM) for dual-function circuits
Choose: WF825657
Because: It delivers the most combined GPM, ideal for high-demand systems with multiple actuators.
If you need: Balanced dual flows (7+7 GPM or 8+6 GPM) for parallel operations
Choose: WF825654 or WF825651
Because: These models deliver similar flows from both pump sections, useful for circuits requiring simultaneous, balanced outputs.
If you need: High front section flow with minimal rear flow (Hi-Lo circuit)
Choose: WF825659
Because: The front pump delivers 11 GPM, rear only 1 GPM — ideal for Hi-Lo applications or systems with one main and one auxiliary flow.
If you need: Minimal rear pump output or single circuit (lowest total flow)
Choose: WF825975
Because: Rear pump is inactive (0 GPM); choose this for strictly single-circuit applications or lowest total volume.
If you need: Specific port orientation for tight installations
Choose: WF825659 (90° CCW) or WF825975 (180°)
Because: Alternative port locations help with unique plumbing requirements in compact or custom equipment.
If you need: High-speed drive compatibility (up to 3000 RPM)
Choose: WF825654
Because: Rated for the highest maximum speed, suitable for fast-running prime movers.
If you need: Splined shaft for high-torque or flexible coupling
Choose: WF825654 or WF825975
Because: 13-tooth splined shafts handle higher torque loads and allow more flexible coupler options.
Compatibility: All models feature SAE ‘B’ 4-bolt flange mounting and 1-1/16″-12 UN-2B/straight thread ports, ensuring 100% direct interchangeability with Vickers models and easy swap-in for existing systems.
