Product Selection Guide
These FluiDyne V20 Series vane pumps are all direct Vickers replacements, offering 100% interchangeability and designed for hydraulic systems requiring reliable performance. The primary differences among these models are flow rate, displacement, shaft configuration, port orientation, and mounting details, which directly affect suitability for specific system layouts and power requirements.
?? 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 |
|---|---|---|---|---|
| WF820049 (Current) | 8.4 GPM | 2500 PSI | 26.6 cm³/r (1.62 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820048 | 13.5 GPM | 2500 PSI | 42.6 cm³/r (2.60 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820044 | 13.5 GPM | 2500 PSI | 42.6 cm³/r (2.60 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8201811 | 13.5 GPM | 2500 PSI | 42.6 cm³/r (2.60 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8201212 | 13.5 GPM | 2500 PSI | 42.6 cm³/r (2.60 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Flow Rate & Displacement
Difference: WF820049 delivers 8.4 GPM at 1.62 in³/rev, while WF8201811, WF820048, WF820044, and WF8201212 each supply 13.5 GPM at 2.60 in³/rev.
Selection Guide: Choose WF820049 for lower flow, precise applications or smaller actuators, or explore other single stage vane pumps for similar requirements. Select any of the 13.5 GPM models for larger cylinders or higher-flow circuits.
Mounting & Port Configuration
Difference: WF820049, WF820048, WF8201811, and WF8201212 use SAE ‘A’ 2-bolt flanges; WF820044 is listed as SAE ‘B’ flange in the description but shares most specs with the SAE ‘A’ models.
Selection Guide: Match pump flange to your system’s mounting pad. Use SAE ‘A’ for most standard applications; select SAE ‘B’ only if your setup requires it.
Shaft Type & Extension
Difference: WF820049, WF820048: 3/4″ straight shaft with key (2.66″ extension). WF8201811: 3/4″ straight shaft with key (1.75″ extension). WF8201212: 7/8″ threaded shaft with Woodruff key. WF820044: special shaft configuration (Code 20).
Selection Guide: Choose shaft type based on coupling style and torque needs. Use standard 3/4″ keyed shafts for compatibility with most couplings; select the 7/8″ threaded shaft if required by your drive; special shaft codes for unique installations.
Port Orientation & Thread Type
Difference: WF820049, WF8201811: Inline port positions (0°). WF8201212: ports opposite (180°). WF820044: outlet is 90° counter-clockwise from inlet. WF820049 and WF8201811 offer NPT ports; others use BSPP threads or specified flanges.
Selection Guide: Choose port orientation to match your plumbing layout (inline for straight runs, 90° for compact systems). Match port thread type (NPT or BSPP) to your hose or fitting standards. Our V201P8P10D11R model offers similar porting if an alternate configuration is needed.
Maximum Speed & Pressure
Difference: WF820049: 2800 RPM max, 2500 PSI. Others: 2400 RPM max, 2500 PSI.
Selection Guide: WF820049 supports higher speeds—choose for fast cycling systems. All models rated to 2500 PSI, suitable for most medium-pressure hydraulics.
Quick Selection Guide
If you need: Lower flow with higher RPM capability (8.4 GPM @ 2800 RPM)
Choose: WF820049
Because: Ideal for compact systems or applications requiring faster shaft speeds and lower displacement.
If you need: Standard high flow (13.5 GPM) with 3/4″ straight shaft and inline ports (NPT threads)
Choose: WF820048 or WF8201811
Because: Common configuration for general hydraulic use; select WF820048 for longer shaft extension.
If you need: 13.5 GPM with special shaft or non-standard port orientation
Choose: WF820044 or WF8201212
Because: WF820044 offers a special shaft and 90° porting for tight installations; WF8201212 provides a threaded shaft and 180° port layout for unique setups.
Compatibility: All models are 100% Vickers-interchangeable and built to SAE J744 standards, with shared SAE ‘A’ mounting and similar port sizing for easy drop-in replacement. For a broader overview of compatible solutions, see our Vickers replacement pumps page.
