Product Selection Guide
All five Fluidyne V20 Series models are direct Vickers replacements, offering 100% interchangeability and sharing core performance specs, but they differ in flow rate, displacement, port size/type, shaft configuration, port position, and mounting flange size. For a full range of hydraulic pumps including various vane, gear, and piston configurations, explore our main product family. If you’re interested specifically in vane pumps applications, review our dedicated category for additional options and technical resources. For single model applications, see our single stage vane pumps overview for technical comparisons. These differences impact compatibility with your hydraulic system, space constraints, and coupling 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 |
|---|---|---|---|---|
| WF820048 (Current) | 13.5 GPM | 2500 PSI | 42.6 cm³/r (2.60 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820049 | 8.4 GPM | 2500 PSI | 26.6 cm³/r (1.62 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) |

Key Differences
Flow Rate & Displacement
Difference: WF820049 delivers 8.4 GPM (1.62 in³/r), while WF820048, WF820044, WF8201811, and WF8201212 each deliver 13.5 GPM (2.60 in³/r).
Selection Guide: Select WF820049 for lower flow/pressure applications or when system efficiency at lower speeds is required. The other models suit higher flow systems or larger actuators.
Mounting Flange
Difference: WF820044 uses a 2-bolt SAE ‘B’ flange; all others use 2-bolt SAE ‘A’.
Selection Guide: Choose WF820044 only if your system requires an SAE ‘B’ mount; otherwise, the others fit SAE ‘A’ applications.
Shaft Configuration
Difference: WF820048, WF820049, and use a 3/4″ straight keyed shaft; has a 7/8″ threaded shaft with Woodruff key; WF820044 uses a special shaft (Code 20).
Selection Guide: Select a shaft matching your coupling and torque needs. Use for threaded shaft applications or when a Woodruff key is required.
Port Thread Type & Size
Difference: WF820049, , and use NPT threads; WF820048 uses straight thread (SAE), and WF820044 uses a flange inlet and special outlet port.
Selection Guide: Pick a model with ports matching your system’s thread type—NPT for legacy US systems, straight thread or flange for modern or OEM requirements.
Port Position
Difference: WF820048, WF820049, and have inline ports (0°); WF820044 has outlet port at 90° CCW; has outlet 180° opposite inlet.
Selection Guide: Choose port orientation based on your piping layout—inline for straightforward connections, 90° or 180° for tight or angled installations.
Maximum Speed
Difference: WF820049 allows up to 2800 RPM; others rated to 2400 RPM.
Selection Guide: Select WF820049 for higher-speed motor drives or variable speed applications.
Quick Selection Guide
If you need: Low flow, high-speed compatibility
Choose: WF820049
Because: Delivers 8.4 GPM, supports up to 2800 RPM, and fits applications with smaller actuators or where reduced flow is needed.
If you need: Standard flow with compact SAE ‘A’ mounting and inline ports
Choose: WF820048
Because: Offers 13.5 GPM, standard 3/4″ straight shaft, and inline porting for straightforward installations.
If you need: Standard flow but require SAE ‘B’ flange mounting
Choose: WF820044
Because: Same flow/displacement as WF820048 but with SAE ‘B’ flange and 90° outlet for alternative mounting/porting needs.
If you need: Standard flow with NPT ports and special shaft
Choose: or
Because: Both offer 13.5 GPM and use NPT threads; features a threaded shaft for unique coupling, has a special shaft configuration for specific applications.
Compatibility: All models are 100% interchangeable with Vickers replacement pumps and follow SAE J744 standards. Most feature SAE ‘A’ 2-bolt mounting and G1″/G1/2″ BSPP straight thread ports for simplified system integration.
