Product Selection Guide
The primary differences among these FluiDyne V20 Series pump models are flow rate, displacement, shaft configuration, port orientation, and port type. All models are direct Vickers replacements with full SAE ‘A’ 2-bolt flange mounting and BSPP port compatibility, making them easy drop-in solutions for existing systems. For advanced features, view our line of pumps with integral valves. Selection comes down to matching flow needs, shaft/coupling style, and port layout to your application.
?? 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 |
|---|---|---|---|---|
| WF820044 (Current) | 13.5 GPM | 2500 PSI | 42.6 cm³/r (2.60 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) |
| WF820049 | 8.4 GPM | 2500 PSI | 26.6 cm³/r (1.62 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 (1.62 in³/r), while all other models provide 13.5 GPM (2.60 in³/r) at 1200 RPM.
Selection Guide: Select WF820049 for smaller systems or when lower flow is required; choose any of WF820044, WF820048, WF8201811, or WF8201212 for higher flow hydraulic circuits.
Port Thread Type & Orientation
Difference: WF820048 uses 1-5/8″ and 1-1/16″ straight threads; WF820049, , and use NPT threads; all models feature G1″/G1/2″ BSPP straight thread ports. Port positions are either inline (0°), 90° counter-clockwise, or 180° from inlet.
Selection Guide: Choose port orientation and thread type matching your hose/fitting setup. Inline ports (0°) are best for straightforward plumbing; 90° or 180° positions suit tight or angled installations.
Shaft Configuration
Difference: Shafts vary between 3/4″ straight keyed (standard), special configurations (Code 20 or 39), and a 7/8″ threaded shaft (). Extension lengths differ (1.75″ or 2.66″).
Selection Guide: Pick the shaft type and extension compatible with your drive coupling and torque needs. Splined or heavy-duty shafts are preferred for high-torque, while threaded shafts work with certain pulley or flange setups.
Port Position
Difference: WF820044 is 90° counter-clockwise from inlet; WF820048, WF820049, and are inline (0°); is opposite (180°).
Selection Guide: 90° ports (WF820044) help in side-entry installations; inline (0°) simplifies direct hose routing; 180° is suitable when inlet and outlet need to be on opposite sides.
Quick Selection Guide
If you need: Lower flow (8.4 GPM at 1200 RPM) for compact or precision circuits
Choose: WF820049
Because: It offers the smallest displacement and flow, ideal for smaller actuators or slower system speeds.
If you need: Standard flow (13.5 GPM) with 90° port orientation
Choose: WF820044
Because: Its 90° port rotation solves installation challenges in confined spaces.
If you need: Standard flow with inline porting and standard shaft
Choose: WF820048
Because: It provides straightforward plumbing and a conventional 3/4″ straight keyed shaft.
If you need: Standard flow with NPT port threads and special shaft configuration
Choose:
Because: Best for systems already using NPT fittings and where a special shaft (Code 39) is advantageous.
If you need: Standard flow with threaded shaft and port positions opposite (180°)
Choose:
Because: The 7/8″ threaded shaft and 180° port layout suit specialized couplings or installations where inlet and outlet must be on opposing sides.
Compatibility: All models are fully interchangeable with Vickers V20 pumps and use SAE ‘A’ 2-bolt flange mounting with G1″/G1/2″ BSPP ports, supporting direct replacement in most applications.
