Product Selection Guide
These FluiDyne V20 Series hydraulic vane pumps share direct Vickers interchangeability and SAE ‘A’ 2-bolt flange mounting but differ mainly in flow rate, displacement, rotation direction, shaft type, port types, port orientation, and cover features. Selection should be based on required flow, pressure, porting configuration, rotation, and special functions like flow control.
?? 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 |
|---|---|---|---|---|
| WF820703 (Current) | 11.5 GPM | 2500 PSI | 36.3 cm³/r (2.22 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820704 | 8.4 GPM | 2500 PSI | 26.6 cm³/r (1.62 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820705 | 11.5 GPM | 2500 PSI | 36.3 cm³/r (2.22 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820702 | 11.5 GPM | 2500 PSI | 36.3 cm³/r (2.22 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: WF820704 offers 8.4 GPM (1.62 in³/rev), WF820703 and WF820705 provide 11.5 GPM (2.22 in³/rev), WF8201811 delivers 13.5 GPM (2.60 in³/rev), and WF820702 provides 11.5 GPM (2.22 in³/rev) with flow control.
Selection Guide: Select a model with a flow rate and displacement that matches your system’s actuator speed and overall hydraulic demand.
Port Type & Orientation
Difference: WF820703/704 have straight thread ports with ports 90° clockwise from inlet; WF820705/1811 have NPT ports inline with inlet (0°); WF820702 has a mix of NPT and straight thread ports, with a special flow control cover.
Selection Guide: Choose 90° port orientation for compact installations; select inline ports for straightforward hose routing. Match thread style (NPT/BSPP) to your plumbing.
Shaft & Rotation
Difference: WF820703: 9-tooth splined shaft, right-hand; WF820704/705/1811: 3/4″ keyed shaft, right-hand; WF820702: 11-tooth splined shaft, left-hand.
Selection Guide: Select shaft and rotation to match motor/coupling and drive direction. Use splined shafts for higher torque; keyed shafts for standard applications.
Cover & Special Functions
Difference: WF820702 includes a flow control cover (8 GPM) and built-in relief valve (2000 PSI), while others use standard covers. For more options, see our pumps with integral valves.
Selection Guide: Choose the flow control cover model (WF820702) if you need integrated flow regulation and pressure relief.
Pressure & Speed Ratings
Difference: All standard models rated to 2500 PSI; WF8201811 is limited to 2200 PSI. Max speeds range from 2400 to 2800 RPM.
Selection Guide: For higher-speed or lower-pressure systems, verify that the selected model’s limits match your requirements.
Quick Selection Guide
If you need: Lower flow for smaller actuators or circuits
Choose: WF820704
Because: It delivers 8.4 GPM at 1200 RPM with a compact displacement.
If you need: Standard 11.5 GPM flow with splined shaft and 90° ports
Choose: WF820703
Because: It offers a right-hand rotation, 9-tooth splined shaft, and 90° outlet orientation for specific mounting needs.
If you need: Standard 11.5 GPM flow with keyed shaft and inline ports
Choose: WF820705
Because: It has a 3/4″ keyed shaft and inline porting for straightforward hose routing.
If you need: Integrated flow control and relief valve
Choose: WF820702
Because: It provides 11.5 GPM with an 8 GPM flow control, 2000 PSI relief, and left-hand rotation.
If you need: Maximum flow in this group (13.5 GPM)
Choose: WF8201811
Because: It has the highest displacement (2.60 in³/rev) and flow, ideal for larger systems.
Compatibility: All models feature SAE J744 ‘A’ 2-bolt flange mounting and are 100% interchangeable with Vickers V20 series applications, ensuring easy retrofit or replacement in existing systems.
