- stationary power units
- test stands
Important: Verify pump model WF825855 matches your existing Vickers unit before ordering. For technical assistance, contact (800) 823-4937.
Product Selection Guide
These FluiDyne V2020 double vane pumps differ mainly in total flow rate, front/rear section output, rotational direction, shaft type, and port orientation. Compare with other pumps with integral valves applications for specialized systems. All are direct Vickers replacements with SAE ‘B’ 4-bolt flanges and are suitable for applications requiring two separate flows from a single compact unit.
?? 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 |
|---|---|---|---|---|
| WF825855 (Current) | 7 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825857 | 13 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825852 | 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) |
| WF825063 | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Total Flow Rate
Difference: WF825857 delivers the highest total flow (22.0 GPM), followed by WF825852 (18.0 GPM), WF825855 (14.0 GPM), and WF825975/WF825063 (10.0 GPM each).
Selection Guide: Choose WF825857 for high-demand circuits where maximum combined flow is needed; WF825975/WF825063 for low-flow dual-circuit requirements.
Front/Rear Pump Output
Difference: WF825857: 13/9 GPM; WF825852: 9/9 GPM; WF825855: 7/7 GPM; WF825975/WF825063: 10/0 GPM (rear section inactive).
Selection Guide: Opt for equal-output models (WF825852, WF825855) for balanced dual circuits; split-output (WF825857) for systems needing different flows; single-section (WF825975, WF825063) when only one flow is required but double pump mounting is preferred.
Maximum Speed
Difference: WF825855: 3000 RPM; WF825857: 2400 RPM; WF825852: 2800 RPM; WF825975/WF825063: 1800 RPM.
Selection Guide: High-speed applications should use WF825855 (up to 3000 RPM); WF825975/WF825063 are best for lower-speed requirements.
Rotation Direction
Difference: WF825855 and WF825063 are right-hand (clockwise); WF825857, WF825852, and WF825975 are left-hand (counter-clockwise).
Selection Guide: Match rotation to your system’s drive—select right-hand or left-hand as needed for your motor orientation.
Shaft Type
Difference: WF825855, WF825975, WF825063: 13-tooth splined; WF825857, WF825852: straight keyed shaft.
Selection Guide: Select splined shafts for higher torque or flexible couplings; choose straight keyed shafts for standard coupler applications.
Port Orientation
Difference: WF825855: both outlets 90° CW from inlet; WF825857: both outlets 90° CCW; WF825852: front opposite (180°), rear inline (0°); WF825975/WF825063: both outlets opposite inlet (180°). For specs on single-section options, see the V201P5P18C11R – FluiDyne V20 Pump.
Selection Guide: Choose models with outlet orientation that best fits your plumbing layout to simplify installation and reduce fittings.
Quick Selection Guide
If you need: Highest combined flow for dual circuits (up to 22 GPM) and split flows
Choose: WF825857
Because: Provides 13 GPM front and 9 GPM rear with left-hand rotation for applications requiring large and small section flows.
If you need: Balanced dual outputs (equal front and rear flow) at moderate rates
Choose: WF825852 (9/9 GPM, 18 GPM total) or WF825855 (7/7 GPM, 14 GPM total)
Because: Ideal for two similar hydraulic actuators or circuits.
If you need: Single output from a double pump housing for future expansion or mounting flexibility
Choose: WF825975 (left-hand) or WF825063 (right-hand)
Because: Delivers 10 GPM from front section only, with rear section inactive.
If you need: Highest RPM capability for faster cycling
Choose: WF825855
Because: Supports up to 3000 RPM (front pump limited), suitable for high-speed applications.
If you need: Specific shaft or rotation configuration
Choose: WF825857/WF825852 for straight keyed, left-hand; WF825855/WF825063 for splined, right-hand; WF825975 for splined, left-hand
Because: Select to match your drive and torque requirements.
Compatibility: All models feature SAE ‘B’ 4-bolt flange mounting and 1-1/16″-12 UN-2B threaded outlets, ensuring direct Vickers compatibility and straightforward interchange with standard hydraulic system layouts.
