Product Selection Guide
These FluiDyne V2020 double vane pumps differ primarily in front/rear flow capacities, maximum RPM, shaft type, rotation direction, and port orientation. All are direct Vickers replacements, follow SAE J744 mounting, and are built for up to 2500 PSI operation. Selection depends on required total flow, desired front/rear flow split, system rotation, and shaft/coupling needs. For more options, view all our hydraulic pumps.
?? 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 |

Key Differences
Front/Rear Flow Ratings
Difference: WF825659 delivers 11 GPM front and 1 GPM rear (total 12 GPM); WF825657 delivers 11 GPM front and 7 GPM rear (total 18 GPM); WF825654 and WF825651 both provide 7–8 GPM front and 6–7 GPM rear (total 14 GPM); WF825975 is 10 GPM front only (rear pump inactive, total 10 GPM).
Selection Guide: Choose WF825657 for high combined flow (18 GPM) or WF825659 for applications needing a small secondary circuit. Select WF825975 for single-circuit needs at 10 GPM.
Maximum RPM
Difference: WF825654 reaches 3000 RPM (highest); WF825651 up to 2800 RPM; WF825657 up to 2500 RPM; WF825659 and WF825975 limited to 1800 RPM by rear pump.
Selection Guide: Select WF825654 for high-speed applications requiring up to 3000 RPM; WF825659 or WF825975 for lower speed systems (up to 1800 RPM).
Shaft Type
Difference: WF825654 and WF825975 feature a 13-tooth splined shaft; others use a straight keyed shaft.
Selection Guide: Choose splined shaft models for high-torque or splined-coupling setups; straight keyed for standard couplings.
Rotation Direction
Difference: WF825659 and WF825651 are right-hand (clockwise); WF825657, WF825654, and WF825975 are left-hand (counter-clockwise).
Selection Guide: Match pump rotation to your drive motor—select right-hand models for clockwise, left-hand for counter-clockwise systems.
Port Orientation
Difference: WF825659: outlets 90° CCW from inlet; WF825657, WF825654, WF825651: outlets inline (0°) with inlet; WF825975: outlets opposite inlet (180°).
Selection Guide: Choose port orientation based on plumbing layout—inline for straight runs, 90° or 180° for compact or specific routing needs. For more vane pump options, see our single stage vane pumps catalog.
Quick Selection Guide
If you need: High total flow (18 GPM) with two circuits
Choose: WF825657
Because: Provides a balanced 11 GPM front and 7 GPM rear, ideal for systems requiring significant simultaneous flows.
If you need: Two moderate flows (7–8 GPM front, 6–7 GPM rear) at high RPM
Choose: WF825654 or WF825651
Because: Both provide 14 GPM total; WF825654 allows up to 3000 RPM and splined shaft option for high torque.
If you need: Primary flow with minimal secondary flow (e.g., pilot circuit)
Choose: WF825659
Because: 11 GPM front/1 GPM rear output suits main/auxiliary circuit applications.
If you need: Single circuit, 10 GPM, with splined shaft
Choose: WF825975
Because: Rear pump is inactive; select when only one output is required and system uses splined coupling.
Compatibility: All models are 100% interchangeable with Vickers V2020, share SAE J744 mounting, and use G1″/G1/2″ BSPP ports for straightforward replacement. For applications requiring integral valves, see our pumps with integral valves.

Installed without any trouble and it's putting out good pressure. Took a little while longer to ship than the listing said, but it got here and works fine so can't complain too much.
Customer brought in a machine with a worn out Vickers pump, sourced this as the replacement and it was 100% interchangeable — same bolt pattern, same shaft, everything lined up perfect. Been a few weeks and the customer hasn't called back, which is always a good sign.
works good so far, been about three weeks running it pretty hard on the log splitter. only reason not five stars is i haven't put enough hours on it yet to say for certain it'll hold up long term.
fit perfect, shipped fast
Dropped it in place of the old Vickers unit, fired up the machine and had full pressure immediately. Couldn't ask for more.
