Important: Verify pump model WF825979 matches your existing Vickers unit before ordering. For technical assistance, contact (800) 823-4937.
Product Selection Guide
These FluiDyne V2020 double vane pumps differ primarily in total flow rate, outlet port orientation, shaft type, rotation direction, and maximum speed. For a broader overview, browse our complete vane pump selection. All models are direct Vickers replacements with 100% interchangeability (see Vickers replacement options), conform to SAE mounting and port standards, and handle up to 2500 PSI. Selection depends on flow/output requirements, system layout, and drive 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 |
|---|---|---|---|---|
| WF825979 (Current) | 9 | 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) |
| WF825976 | 8 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825063 | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825884 | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Total Flow Rate
Difference: WF825979 delivers up to 17.0 GPM (9+8 GPM across two sections), while WF825976 provides 16.0 GPM (8+8 GPM). WF825975, WF825063, and WF825884 deliver 10.0 GPM (single active section).
Selection Guide: Choose WF825979 or WF825976 for higher flow (two active sections); select WF825975, WF825063, or WF825884 for applications needing only 10 GPM and a secondary inactive section.
Pump Section Configuration
Difference: WF825979 and WF825976 feature both front and rear pumps active; the others have a rear pump with zero flow (effectively single section).
Selection Guide: For dual-circuit or hi-lo systems, use WF825979 or WF825976; for single flow systems, use WF825975, WF825063, or WF825884.
Maximum Speed
Difference: WF825979 and WF825976 operate up to 2800 RPM; others are limited to 1800 RPM due to the rear pump section.
Selection Guide: Select WF825979 or WF825976 for higher speed drives or when matching to fast-turning prime movers.
Rotation Direction
Difference: WF825979, WF825975, WF825976, and WF825884 are Left-Hand (Counter-Clockwise); WF825063 is Right-Hand (Clockwise).
Selection Guide: Match pump rotation to your drive direction—choose WF825063 if your system requires clockwise rotation.
Port Orientation
Difference: WF825979, WF825975, and WF825063 have both outlets opposite the inlet (180°); WF825976 has outlets 90° CCW from inlet; WF825884 has outlets inline with inlet (0°).
Selection Guide: Select port orientation for optimal hose routing: 180° for standard setups, 90° for compact or offset installations, 0° for direct inline connections.
Shaft Type
Difference: WF825979 uses a straight keyed shaft; others use 13-tooth splined shafts.
Selection Guide: Use splined shafts (WF825975, WF825976, WF825063, WF825884) for higher torque/longer life or when system requires splined coupling. Use straight keyed shaft (WF825979) for standard keyed couplings.
Quick Selection Guide
If you need: Dual-flow output for Hi-Lo circuits or simultaneous circuits (total 16-17 GPM)
Choose: WF825979 (9+8 GPM, 2800 RPM) or WF825976 (8+8 GPM, 2800 RPM)
Because: Both front and rear pumps are active, maximizing system versatility and flow.
If you need: Single output (10 GPM), with specific port orientation or rotation
Choose: WF825975 (180°, left-hand), WF825063 (180°, right-hand), or WF825884 (0°, left-hand)
Because: These models provide single active flow and let you select for port direction and rotation.
If you need: Splined shaft for high torque or keyed shaft for standard drives
Choose: WF825979 for straight key; others for 13-tooth spline
Because: Choose based on your coupling and torque requirements.
If you need: Maximum pump speed up to 2800 RPM
Choose: WF825979 or WF825976
Because: Only these models support higher speeds due to both pump sections being active.
Compatibility: All models are 100% Vickers interchangeable, feature SAE ‘B’ 4-bolt mounting, and G1″/G1/2″ BSPP straight thread ports for seamless integration.

Running it on a log splitter rebuild. Pressure is strong and consistent, no leaks after a full weekend of heavy use. Would buy again without hesitation.
works great
Pump runs well and the fitment was spot on. Only reason I'm not giving it full marks is the packaging was a little roughed up when it arrived — pump itself was fine though, so can't complain too much.
Bolted up to the old Vickers mount without any modifications, fired it right up and had full pressure immediately. Thing's a beast for the price.
Ordered it on a Tuesday, had it by Thursday. Fit the machine exactly like the original and haven't had a single issue since install.
