Product Selection Guide
These FluiDyne V20 Series vane pumps are all direct Vickers replacements, designed with SAE ‘A’ 2-bolt flanges and G1″/G1/2″ BSPP ports, but differ in flow rate, displacement, shaft configuration, and max pressure. The main selection factors are flow (GPM), displacement (in³/rev), pressure rating, and shaft/port details. Browse our full range of hydraulic pumps for additional options.
?? 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 |
|---|---|---|---|---|
| WF820493 (Current) | 11.5 GPM | 2500 PSI | 36.3 cm³/r (2.22 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820498 | 13.5 GPM | 2500 PSI | 42.6 cm³/r (2.60 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820499 | 8.4 GPM | 2500 PSI | 26.6 cm³/r (1.62 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820494 | 8.4 GPM | 2500 PSI | 26.6 cm³/r (1.62 in³/r) | 2-Bolt Flange (SAE “A” size) |
| V201P13P39C11R – FluiDyne V20 Pump (42.6 cm³/r (2.60 in³/r)) | 13.5 GPM | 2500 PSI | 42.6 cm³/r (2.60 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Flow Rate
Difference: Models span from 8.4 GPM (WF820499, WF820494) to 13.5 GPM (WF820498, WF8201811). For single-stage applications, see our single stage vane pumps selection. WF820493 sits at 11.5 GPM.
Selection Guide: Choose higher GPM models (WF820498, WF8201811) for applications needing more hydraulic flow; select lower GPM (WF820499, WF820494) for precise, lower-volume circuits.
Displacement
Difference: Displacement ranges from 1.62 in³/rev (WF820499, WF820494) to 2.60 in³/rev (WF820498, WF8201811), with WF820493 in the middle at 2.22 in³/rev.
Selection Guide: Match displacement to your required actuator speed—higher displacement means more fluid per revolution.
Maximum Pressure
Difference: WF820498 and WF8201811 are rated 2200 PSI in the description but 2500 PSI in detailed specs. All others (WF820493, WF820499, WF820494) are consistently rated at 2500 PSI.
Selection Guide: Use WF820493, WF820499, or WF820494 for systems needing full 2500 PSI; verify actual requirements if selecting WF820498 or WF8201811.
Shaft Configuration
Difference: WF820493 offers a 9-tooth splined shaft (1.25″), all others use a 3/4″ straight shaft with key (1.75″ extension); some have special shaft codes (15, 31, 39).
Selection Guide: Choose splined (WF820493) for high torque or if matching an existing splined coupling; use keyed models for standard replacements. For similar performance, consider V201P13P3C11R – FluiDyne V20 Pump.
Port Thread Type
Difference: WF820493 uses 1-5/8″ and 1-1/16″ straight threads, while the others use 1-1/4″ NPT (inlet) and 3/4″ NPT (outlet) in the description and G1″/G1/2″ BSPP in specs.
Selection Guide: Select the model with ports matching your system’s existing fittings for easier installation.
Maximum Speed
Difference: WF820499 and WF820494 support up to 2800 RPM; the rest are rated for 2400–2500 RPM.
Selection Guide: For high-speed drive applications, choose WF820499 or WF820494.
Quick Selection Guide
If you need: A balance of moderate flow and high pressure with splined shaft
Choose: WF820493
Because: It delivers 11.5 GPM at up to 2500 PSI, with a 9-tooth splined shaft for high-torque couplings.
If you need: Maximum flow (13.5 GPM) at up to 2500 PSI with keyed shaft
Choose: WF820498 or WF8201811
Because: These models offer the highest flow rate among the group, suitable for larger actuators or faster cycle times.
If you need: Lower flow (8.4 GPM) with higher RPM capability
Choose: WF820499 or WF820494
Because: These support up to 2800 RPM, ideal for faster-running systems or smaller actuators.
If you need: Keyed shaft with specific shaft code (for custom fitment)
Choose: WF820499 (Shaft Code 15), WF820494 (Code 31), or WF8201811 (Code 39)
Because: Use these if your application requires non-standard shaft options.
Compatibility: All models are 100% interchangeable with Vickers replacement pumps and conform to SAE J744 mounting standards. Port sizes and bolt patterns are consistent for direct drop-in replacement.
