Product Selection Guide
These FluiDyne V2020 double vane pump models are all direct Vickers replacements, sharing core features like SAE ‘A’ mounting, 3/4″ straight keyed shafts, and G1″/G1/2″ BSPP ports. Their key differences are in flow rates, total displacement, maximum speed, rotation direction, port orientation, and shaft type—factors critical to matching your hydraulic system’s design and performance needs.
?? 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 |
|---|---|---|---|---|
| WF825881 (Current) | 11 | 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) |
| WF825889 | 7 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825885 | 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) |
Key Differences
Flow Rate
Difference: Models provide total flows from 10.0 GPM (WF825884, WF825975) up to 15.0 GPM (WF825885). WF825881 offers 12.0 GPM and WF825889 13.0 GPM.
Selection Guide: Select higher flow models (WF825885 for 15.0 GPM) for applications needing faster cycle times or multiple actuators. Choose lower flow (WF825884, WF825975) for smaller systems or precise control.
Pump Configuration (Front/Rear Sections)
Difference: Some models have both front and rear sections producing flow (WF825889: 7 + 6 GPM, WF825885: 9 + 6 GPM), while others have only the front section active (WF825884, WF825975: 10 + 0 GPM).
Selection Guide: Choose dual-output models (WF825889, WF825885, WF825881) if you require two separate flows or Hi-Lo circuit operation. Single-output (WF825884, WF825975) is ideal if only one flow is needed.
Maximum Speed
Difference: WF825889 can operate up to 3000 RPM, WF825885 up to 2800 RPM, while others are limited to 1800 RPM by the rear pump section.
Selection Guide: For high-speed drives or where compact size is needed for a given flow, select WF825889 or WF825885. For standard speeds, the other models suffice. See also V201P5P18C11R for similar single-section high-RPM applications.
Rotation Direction
Difference: WF825881, WF825884, WF825975 rotate left-hand (counter-clockwise); WF825889 and WF825885 rotate right-hand (clockwise).
Selection Guide: Match pump rotation to your existing drive—left-hand models for counter-clockwise shafts, right-hand for clockwise.
Port Orientation
Difference: WF825884: inline (0°), WF825881 & WF825885: both outlets 90° CCW from inlet, WF825975: both outlets opposite inlet (180°), WF825889: front 90° CCW, rear inline.
Selection Guide: Choose outlet orientation that best matches your piping layout: 90° for side connections, inline or 180° for straight-through lines.
Shaft Type
Difference: WF825881, WF825884, WF825889, WF825975 use a 13-tooth splined shaft; WF825885 uses a straight keyed shaft.
Selection Guide: Splined shafts are preferred for higher torque and durability; straight keyed shafts are common for standard couplings.
Displacement
Difference: Front and rear pump displacement varies by GPM; for example, WF825889 and WF825885 rear pump: 1.19 in³/rev; others not always specified.
Selection Guide: If matching an existing system, verify required displacement per revolution for compatibility. Explore other V20 series models for varying displacement needs.
Quick Selection Guide
If you need: Two independent flows from one pump (Hi-Lo circuit, dual actuator supply)
Choose: WF825889 (7 + 6 GPM, up to 3000 RPM), WF825885 (9 + 6 GPM, up to 2800 RPM), or WF825881 (11 + 1 GPM, up to 1800 RPM)
Because: These provide dual-section output, ideal for systems requiring two flow rates and are a key part of our single stage vane pumps selection.
If you need: Single flow with simple plumbing (one pump section active)
Choose: WF825884 or WF825975 (10 + 0 GPM)
Because: Rear section is inactive, simplifying installation and reducing potential leak paths.
If you need: Highest available flow and speed
Choose: WF825885 (15.0 GPM, 2800 RPM) or WF825889 (13.0 GPM, 3000 RPM)
Because: These models combine high flow and speed, supporting demanding applications.
If you need: Specific port orientation to fit existing piping
Choose: WF825884 for inline outlets, WF825881/885 for 90° CCW, WF825975 for 180° opposite
Because: Choosing the right orientation minimizes piping changes and installation effort.
If you need: Matching rotation to your drive
Choose: WF825881, WF825884, WF825975 for left-hand (CCW); WF825889, WF825885 for right-hand (CW)
Because: Pump rotation must match your system’s drive rotation.
Compatibility: All models are 100% interchangeable with Vickers equivalents, use SAE ‘A’ mounting, and feature G1″/G1/2″ BSPP ports for straightforward swap-in replacement. Volume pricing begins at 4 units and each pump is covered by a 12-month manufacturer warranty. Same-day shipping is available for in-stock items.
