It is a V2020 series double vane pump offering 100% interchangeability with the original Vickers model..
- Mounting Pattern: SAE ‘A’ 2-bolt
- Inlet Port: G1″ BSPP
- Outlet Port: G1/2″ BSPP
Common Applications
Commonly used in marine applications, stationary power units, test stands, or in industrial circuits using FluiDyne V20 pumps for similar applications.
- marine applications
- stationary power units
- test stands
Important: Verify pump model WF825111 matches your existing Vickers unit before ordering. For technical assistance, contact (800) 823-4937.
Product Selection Guide
These FluiDyne V2020 double vane pumps are all direct Vickers replacements, sharing core features like SAE ‘A’ mounting, G1″/G1/2″ BSPP straight thread ports, and a 2500 PSI max pressure rating. The main differences are in flow capacity, pump section outputs, maximum speed, port orientation, shaft type, and rotation direction. These factors determine which model best fits your hydraulic system’s 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 |
|---|---|---|---|---|
| WF825111 (Current) | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251121 | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825115 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825116 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251115 | 12 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Total Flow Rate
Difference: WF8251115 delivers the highest total flow (20.0 GPM), WF825116 offers 19.0 GPM, WF8251121 provides 15.0 GPM, and WF825111 / WF825115 both supply 12.0 GPM.
Selection Guide: Choose WF8251115 or WF825116 for systems needing higher flow rates or to supply multiple actuators with different flow demands.
Front vs Rear Pump Output
Difference: WF825111 and WF825115 have a front-to-rear flow split of 11 GPM / 1 GPM; WF8251121 has a 10 GPM / 5 GPM split; WF825116 and WF8251115 offer higher rear pump outputs (8 GPM).
Selection Guide: Select models with higher rear pump output (WF825116, WF8251115) for circuits requiring significant secondary flow, such as Hi-Lo hydraulic circuits.
Maximum Speed (RPM)
Difference: WF825116 allows higher speeds (up to 2500 RPM); WF8251115 can run at 2400 RPM; others are limited to 1800 RPM.
Selection Guide: Higher RPM models (WF825116, WF8251115) are preferable for systems with faster cycle requirements or when paired with higher-speed motors.
Port Orientation
Difference: WF825111 and WF8251115 have both outlets opposite the inlet (180°); WF825115 has both outlets 90° CW from inlet; WF825116 has both outlets 90° CCW from inlet; WF8251121 has front outlet opposite inlet (180°), rear outlet inline (0°).
Selection Guide: Choose port orientation based on your piping layout—180° is ideal for straight-line installation, 90° for compact or corner installations, and inline rear outlet for simplified rear connections. For specialized requirements, consider pumps with integral valves for integrated system solutions.
Shaft Type
Difference: WF825111 and WF825115 use a 13-tooth splined shaft; others use a straight keyed shaft.
Selection Guide: Splined shafts (WF825111, WF825115) are best for high-torque applications or where positive drive is critical; straight keyed shafts fit standard couplings and are easier to service.
Rotation Direction
Difference: WF825111, WF8251121, and WF8251115 are left-hand (counter-clockwise); WF825115 and WF825116 are right-hand (clockwise).
Selection Guide: Select the correct rotation to match your motor and system design—using the wrong direction can damage the pump or system.
Quick Selection Guide
If you need: Highest total flow and significant rear section output (e.g., dual actuator or Hi-Lo circuit)
Choose: WF8251115 (20.0 GPM total, rear 8 GPM, left-hand rotation)
Because: Provides the largest combined flow and high output from both sections.
If you need: High flow with right-hand rotation and 8 GPM rear output
Choose: WF825116 (19.0 GPM total, rear 8 GPM, right-hand rotation)
Because: Best for right-hand drive applications needing robust secondary flow.
If you need: Balanced front/rear output for split circuits
Choose: WF8251121 (10 GPM front, 5 GPM rear, left-hand rotation)
Because: Ideal for systems with moderate dual demands instead of a dominant main section.
If you need: Compact installation with minimal rear flow
Choose: WF825111 or WF825115 (11/1 GPM, 12.0 GPM total; left/right rotation options)
Because: Maximizes main pump output while supplying a small secondary flow—choose rotation and port orientation to match your setup.
Compatibility: All models are 100% interchangeable with Vickers V2020 series, follow SAE J744 mounting, and use G1″/G1/2″ BSPP ports for straightforward replacement. Volume pricing starts at 4 units and all pumps include a 12-month manufacturer warranty. Same-day shipping available on in-stock items.
