Product Selection Guide
The provided FluiDyne V2020 double vane pump models, part of our broader hydraulic pumps offering, differ primarily in flow rate, pump section sizes, port orientation, shaft type, rotation direction, and maximum speed. All are direct Vickers replacement pumps and provide up to 2500 PSI, but each suits distinct hydraulic circuit needs depending on desired flow, direction, and installation constraints.
?? 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 |
|---|---|---|---|---|
| WF825424 (Current, see also single stage vane pumps) | 8 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825423 | 8 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825421 | 9 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825975 (see full specs) | 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
Flow Rate & Total Displacement
Difference: WF825424 and WF825423 deliver 16.0 GPM (8 GPM per section); WF825421 offers 18.0 GPM (9 GPM per section); WF825975 and WF825063 provide 10.0 GPM (single section active, rear is inactive).
Selection Guide: Select higher flow (WF825421) for applications needing more volume or faster actuation; choose WF825975 or WF825063 for circuits where a single active pump section suffices.
Front/Rear Pump Sections
Difference: WF825424, WF825423, WF825421: Both front and rear pumps are active and identical; WF825975, WF825063: Only the front section is active, rear is inactive (0 GPM).
Selection Guide: Use double-active models (WF825424, WF825423, WF825421) for dual-circuit systems; single-active models (WF825975, WF825063) for simplified or single-circuit needs. If your application requires higher displacement, consider V201P13P3A11R – FluiDyne V20 Pump.
Port Orientation
Difference: WF825424, WF825063, WF825975: Outlets 180° opposite inlet; WF825423: Front outlet inline (0°), rear outlet 90° CW; WF825421: Both outlets 90° CCW from inlet.
Selection Guide: Choose 180° orientation for straightforward plumbing; select 0°/90° or 90° CCW for installations with tight or unique space constraints.
Shaft Type
Difference: WF825424, WF825421, WF825063, WF825975: 13-tooth splined shaft; WF825423: Straight keyed shaft.
Selection Guide: Opt for splined shafts (higher torque, longer life) in demanding or high-cycling applications; select keyed shaft for standard duty or drop-in keyed drives.
Rotation Direction
Difference: WF825424, WF825423, WF825063: Right-hand (clockwise); WF825421, WF825975: Left-hand (counter-clockwise).
Selection Guide: Match pump rotation to your prime mover—right-hand for standard engines/motors (CW), left-hand for reverse-rotation drives.
Maximum Speed
Difference: WF825424, WF825423, WF825421: Up to 2800 RPM; WF825063, WF825975: Limited to 1800 RPM (by rear pump section).
Selection Guide: Select higher RPM models for fast-cycling or high-speed applications; 1800 RPM models for slower, steady operations.
Quick Selection Guide
If you need: Balanced double-pump flow, standard clockwise rotation, and 180° porting
Choose: WF825424
Because: Provides 8+8 GPM, splined shaft, right-hand rotation, and straightforward plumbing.
If you need: Balanced double-pump flow with inline/90° porting and keyed shaft
Choose: WF825423
Because: Provides 8+8 GPM, standard keyed shaft, and flexible port orientations for challenging installations.
If you need: Maximum total flow (18 GPM) and left-hand rotation for reverse-drive systems
Choose: WF825421
Because: Delivers higher 9+9 GPM, left-hand rotation, and splined shaft.
If you need: Single-circuit simplicity or lower total flow at 10 GPM, right-hand rotation
Choose: WF825063
Because: Front pump only (10 GPM), splined shaft, 180° ports, right-hand rotation, ideal for simpler systems.
If you need: Single-circuit, lower flow with left-hand rotation
Choose: WF825975
Because: Front pump only (10 GPM), splined shaft, 180° ports, left-hand rotation.
Compatibility: All models are 100% Vickers interchangeable, use SAE ‘B’ 4-bolt flange mounting, and feature G1″/G1/2″ BSPP straight thread ports. For pumps with advanced control, see our pumps with integral valves. Pressure rating is 2500 PSI across models. Volume pricing is available for orders of 4 or more units, and all pumps include a 12-month manufacturer warranty.
