Product Selection Guide
These FluiDyne V2020 double vane pumps differ primarily in their front/rear pump flow combinations, total output, shaft type, rotation, and port orientation. All are direct Vickers replacements, 100% interchangeable, and feature SAE ‘B’ 4-bolt mounting and standard porting. Selection should be based on required total flow, needed rotation (RH or LH), desired port orientation, and shaft compatibility with your drive system.
?? 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 |
|---|---|---|---|---|
| WF825139 (Current) | 9 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825135 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825134 | 11 | 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 & Pump Combination
Difference: WF825134 delivers the highest total flow at 20.0 GPM (front: 11 GPM / rear: 9 GPM). WF825139 produces 18.0 GPM (front: 9 / rear: 9), WF825135 offers 16.0 GPM (front: 11 / rear: 5), while WF825975 and WF825063 both provide 10.0 GPM (front: 10 / rear: 0). For detailed specs, see the V20201F10S10S11AA30L – FluiDyne V2020 technical page.
Selection Guide: Pick WF825134 if your system needs the highest combined flow or two circuits with higher demands. Choose WF825139 or WF825135 for balanced or asymmetrical flows. Use WF825975 or WF825063 when only one flow output is needed or for simplified double-pump installations.
Maximum Speed
Difference: WF825134 allows up to 2500 RPM; WF825139 up to 2800 RPM (limited by front pump). WF825135 is limited to 1800 RPM (limited by rear pump), as are WF825975 and WF825063.
Selection Guide: For higher speed applications, select WF825139 or WF825134. For lower speed or constant drive situations, WF825135, WF825975, or WF825063 are suitable.
Shaft Type
Difference: WF825139, WF825975, and WF825063 use a 13-tooth splined shaft. WF825134 and WF825135 have straight keyed shafts.
Selection Guide: Choose splined shafts (WF825139, WF825975, WF825063) for higher torque or when splined coupling is required. Select straight keyed shafts (WF825134, WF825135) for standard coupling compatibility.
Rotation Direction
Difference: WF825975 is left-hand (counter-clockwise); all others are right-hand (clockwise).
Selection Guide: If your system requires counter-clockwise rotation, use WF825975. Choose the other models for clockwise drive systems.
Port Orientation
Difference: WF825139: Front 90° CW, Rear 90° CCW. WF825134: Both outlets 180° from inlet. WF825135: Both outlets inline with inlet (0°). WF825975 and WF825063: Both outlets 180° from inlet.
Selection Guide: For specific piping layouts, select port orientation that best matches your installation—90° for side exits, 0° for inline, 180° for opposite-side connections. Compare with the V201P13P3A11R – FluiDyne V20 Pump for large displacement single-stage needs. For systems needing directional control, see our pumps with integral valves category.
Quick Selection Guide
If you need: Highest total output (20.0 GPM) and two high-flow circuits
Choose: WF825134
Because: It provides the largest total flow with flexible port orientation (both outlets opposite inlet) and a straight keyed shaft for common coupling.
If you need: Balanced dual flows at higher speed (up to 2800 RPM)
Choose: WF825139
Because: It offers equal 9 GPM outputs front and rear, a splined shaft for high torque, and unique 90° porting for tight installations.
If you need: Asymmetric dual flows or limited rear circuit
Choose: WF825135
Because: 11 GPM front and 5 GPM rear outputs suit machines needing a dominant high-flow and a smaller secondary flow. Inline porting eases straight connections. For comparable single-stage models, view the V201P5P18C11R – FluiDyne V20 Pump.
If you need: Single flow output from a double pump package
Choose: WF825975 or WF825063
Because: Both deliver 10 GPM from the front section only; select WF825975 for left-hand (CCW) rotation or WF825063 for right-hand (CW) rotation. Both feature splined shafts and 180° porting.
Compatibility: All models are direct Vickers replacements with 100% interchangeability, follow SAE J744 standards, and use SAE ‘B’ mounting with 4-bolt flanges. Ports are standardized for easy integration.
