Product Selection Guide
These FluiDyne single stage vane pump models primarily differ in total flow rate, individual pump section flows, shaft style, rotation direction, and the presence of a priority valve cover. All offer direct Vickers interchangeability, SAE mounting, and 2500 PSI max pressure—see our hydraulic pumps family for more options., but are tailored for different circuit requirements and installation preferences. For a full overview of vane pumps, explore our product family.
?? 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 |
|---|---|---|---|---|
| WF825791 (Current) | 13 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825793 | 6 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825796 | 8 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825975 | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825063 | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Total Flow Rate
Difference: WF825791 delivers the highest total flow at 19.0 GPM (13 GPM front + 6 GPM rear); WF825793 provides 12.0 GPM (6 GPM front + 6 GPM rear); WF825796 offers 14.0 GPM (8 GPM front + 6 GPM rear); WF825975 and WF825063 give 10.0 GPM (10 GPM front + 0 GPM rear).
Selection Guide: Select WF825791 for highest total flow needs, WF825793 for balanced dual outputs, WF825796 for circuits requiring a priority valve, and WF825975 or WF825063 where only a single output is required from a double pump body.
Front/Rear Pump GPM
Difference: WF825791 has the largest front section (13 GPM), WF825796 uniquely offers an 8 GPM front with a priority valve cover, while WF825793 is balanced (6 GPM/6 GPM).
Selection Guide: Choose based on which section needs higher flow—e.g., WF825791 for high primary demand, WF825796 for prioritized flow, WF825793 for equal flows.
Maximum Speed
Difference: WF825791 is limited to 2400 RPM (front section), WF825793 can run up to 3400 RPM, WF825796 to 2800 RPM, WF825975 and WF825063 are limited to 1800 RPM (rear section).
Selection Guide: Use WF825793 for high-speed drive-motor compatibility. Select if lower speed is acceptable.
Shaft Type
Difference: WF825791 and WF825796 use straight keyed shafts; WF825793, WF825975, and WF825063 feature 13-tooth splined shafts.
Selection Guide: Select splined shaft models for higher torque or matching existing splined couplings (see also our FluiDyne V20 pump for similar specs); use keyed shafts for standard couplings.
Rotation Direction
Difference: WF825791, WF825796, and WF825975 are left-hand (counter-clockwise); WF825793 and WF825063 are right-hand (clockwise).
Selection Guide: Choose rotation to match your drive motor’s rotation—incorrect selection leads to pump or system damage.
Priority Valve Cover
Difference: Only WF825796 includes a priority valve cover for flow division.
Selection Guide: Opt for WF825796 in circuits demanding prioritized flow (e.g., steering or braking circuits).
Quick Selection Guide
If you need: Maximum total flow for dual-circuit systems
Choose: WF825791
Because: It delivers up to 19.0 GPM (13 GPM + 6 GPM) at 2500 PSI—ideal for high-demand machinery with two flow requirements.
If you need: Equal split flow for two similar actuators or circuits at high speed
Choose: WF825793
Because: Provides 6 GPM from each section and supports 3400 RPM; ideal for dual-cylinder or dual-motor applications; for similar application needs, see our FluiDyne V20 pump (42.6 cm³/r).
If you need: Priority flow for a safety or critical function
Choose: WF825796
Because: The priority valve ensures one circuit (e.g., steering or braking) always receives flow regardless of main circuit demand.
If you need: Single output from a double pump housing
Choose:
Because: Rear section is inactive (0 GPM); use when only one output is needed but double pump mounting is required.
If you need: Clockwise (right-hand) rotation
Choose: WF825793 or WF825063
Because: These models match right-hand drive requirements.
If you need: High-speed operation (above 2400 RPM)
Choose: WF825793 (up to 3400 RPM)
Because: It supports the highest input speed among these options.
Compatibility: All listed models are direct Vickers replacement pumps applications, meet SAE J744 mounting (SAE ‘B’ 4-bolt flange), and use standard port sizes for easy interchange in existing systems.
