Important: Verify pump model WF825399 matches your existing Vickers unit before ordering. For technical assistance, contact (800) 823-4937.
Product Selection Guide
The primary differences among these FluiDyne V2020 double vane pumps are flow rate, total displacement, maximum speed, shaft type, rotation direction, port orientation, and mounting flange style. Each model is designed to suit particular hydraulic system requirements, from flow demands to 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 |
|---|---|---|---|---|
| WF825399 (Current) | 7 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825390 | 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) |
| WF825884 | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Flow Rate & Total Displacement
Difference: WF825399 delivers 14.0 GPM total (7 GPM front + 7 GPM rear); WF825390 offers 18.0 GPM (9 + 9 GPM); WF825975 applications, WF825063, and WF825884 each provide 10.0 GPM (10 GPM front, 0 GPM rear).
Selection Guide: Select WF825390 for the highest flow applications (18 GPM). WF825399 suits medium flow at 14 GPM and balanced output. WF825975, WF825063, and WF825884 are best for applications needing up to 10 GPM from a single section.
Pump Sections (Dual vs Single)
Difference: WF825399 and WF825390 provide dual output (both front and rear sections are active), while WF825975, WF825063, and WF825884 only use the front pump (rear section is inactive).
Selection Guide: Choose a dual-output model (WF825399, WF825390) for circuits requiring two separate flows/pressures. Choose single-output models (WF825975, WF825063, WF825884) for simpler systems or when only one output is needed.
Maximum Speed
Difference: WF825399 is rated up to 3000 RPM; WF825390 up to 2800 RPM; WF825975, WF825063, and WF825884 up to 1800 RPM.
Selection Guide: For high-speed drives, WF825399 is optimal. For alternative displacement requirements, see V201P5P18C11R – FluiDyne V20 pump. WF825390 supports moderately high speeds. Use the others for lower-speed requirements.
Mounting Flange
Difference: WF825399 uses a Foot Bracket Mount; others (WF825390, WF825975, WF825063, WF825884) use SAE ‘B’ 4-Bolt Flange.
Selection Guide: Select based on your machine’s mounting compatibility.
Shaft Type
Difference: WF825399 and WF825390 have a straight keyed shaft; WF825975, WF825063, and WF825884 come with a 13-tooth splined shaft.
Selection Guide: Choose straight keyed for standard or retrofit installations. Choose splined shafts for high-torque or shock-load applications.
Rotation Direction
Difference: WF825399, WF825390, and WF825063 are right-hand (clockwise); WF825975 and WF825884 are left-hand (counter-clockwise).
Selection Guide: Match the pump rotation to your drive system’s direction.
Port Orientation
Difference: WF825399 and WF825063: both outlets opposite the inlet (180°); WF825390: front outlet 90° CW, rear 90° CCW; WF825884: both outlets inline with inlet (0°); WF825975: both outlets opposite inlet (180°).
Selection Guide: Choose based on piping layout—inline (0°) for straightforward routing, 180° for opposite connections, or 90° for tight or angled spaces. For systems needing integrated pressure control, explore our pumps with integral valves.
Quick Selection Guide
If you need: Highest total flow and dual outputs
Choose: WF825390
Because: It provides 18 GPM (9+9) at up to 2800 RPM, suitable for demanding dual-circuit systems.
If you need: Medium dual flow with high RPM
Choose: WF825399
Because: It offers 14 GPM (7+7) and supports up to 3000 RPM, ideal for balanced dual-output applications with faster drives.
If you need: Single output at 10 GPM, left-hand rotation, 180° outlet
Choose: WF825975
Because: It provides 10 GPM front pump only, left-hand rotation, and 13-tooth splined shaft for specialized layouts. If your application requires higher displacement, review the V201P13P3C11R – FluiDyne V20 Pump for similar industrial uses.
If you need: Single output at 10 GPM, right-hand rotation, 180° outlet
Choose: WF825063
Because: It matches WF825975 specs but with right-hand rotation.
If you need: Single output at 10 GPM, left-hand rotation, inline outlet
Choose: WF825884
Because: It has left-hand rotation and both outlets inline with the inlet (0°), simplifying straight-through piping.
Compatibility: All models are direct Vickers replacements, 100% interchangeable, follow SAE J744 mounting, and use G1″/G1/2″ BSPP straight thread ports.
