Product Selection Guide
These FluiDyne V2020 double vane pump models differ primarily by total flow rate, front/rear pump GPM splits, port orientation, shaft type, rotation, and maximum speed. See all available vane pumps for more selection details. All are direct Vickers replacements with SAE ‘B’ 4-bolt mounting and 2500 PSI rating, but each model is tailored for specific hydraulic system demands—including flow balance, port layout, and drive configuration. For single-stage requirements, our single stage vane pumps offer similar compatibility.
?? 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 |
|---|---|---|---|---|
| WF825257 (Current) | 12 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825258 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825253 | 13 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825252 | 6 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825251 | 9 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Total Flow Rate & Front/Rear Split
Difference: Total flows range from 12.0 GPM (WF825252) up to 20.0 GPM (WF825258), with each model offering distinct front/rear pump GPM combinations (e.g., WF825257 provides 12/6 GPM split, WF825258 offers 11/9 GPM).
Selection Guide: Select a model that matches your system’s required flow and Hi-Lo circuit needs—higher combined flow supports larger actuators or multiple simultaneous functions.
Maximum Speed
Difference: WF825252 offers the highest speed at 3400 RPM, while others are limited between 1800 and 2800/2500 RPM, depending on pump sections.
Selection Guide: Choose WF825252 if your application runs at higher RPM or requires faster response; select lower-RPM models for standard systems or where speed is limited by other components.
Shaft Type
Difference: Some models use a 13-tooth splined shaft (WF825257, WF825252, WF825251), others use a straight keyed shaft (WF825258, WF825253).
Selection Guide: Choose splined shafts for high-torque or splined coupler requirements; keyed shafts suit standard coupling setups.
Rotation
Difference: WF825257 and WF825258 are right-hand (CW) rotation; WF825253, WF825252, and WF825251 are left-hand (CCW) rotation.
Selection Guide: Match the rotation to your prime mover—right-hand for standard engines, left-hand for reverse-driven setups.
Port Orientation
Difference: Models offer various port layouts: both outlets inline (WF825258, WF825252), opposite inlet (WF825253), or mixed (WF825251: front 180°, rear inline; WF825257: front 90° CCW, rear 90° CW).
Selection Guide: Select port orientation based on your plumbing needs: inline for direct, straight runs; 90° or 180° for tight or offset installations.
Quick Selection Guide
If you need: Balanced flow to two circuits with highest combined GPM
Choose: WF825258 (11 GPM front, 9 GPM rear, 20.0 GPM total)
Because: Provides the highest total flow, ideal for dual high-demand functions.
If you need: Even split flow at highest speed capability
Choose: WF825252 (6 GPM front, 6 GPM rear, 12.0 GPM total, max 3400 RPM)
Because: Best for high-speed applications with two equal circuits.
If you need: High flow on one circuit and minimal on the second
Choose: WF825253 (13 GPM front, 1 GPM rear, 14.0 GPM total, CCW rotation)
Because: Useful for primary/auxiliary systems where one circuit needs much less flow.
If you need: Matching flow for two mid-size circuits with splined shaft and CCW rotation
Choose: WF825251 (9 GPM front, 9 GPM rear, 18.0 GPM total)
Because: Balanced output plus splined shaft for higher torque, with left-hand rotation.
If you need: Disparate flows with max front section GPM and splined shaft, CW rotation
Choose: WF825257 (12 GPM front, 6 GPM rear, 18.0 GPM total)
Because: Delivers strong primary flow, supports two different demands.
Compatibility: All models feature SAE ‘B’ 4-bolt mounting, 1-1/16″-12 UN-2B and straight thread ports, and 2500 PSI rating—ensuring direct Vickers interchangeability and simple retrofit in existing systems. Not sure which model fits? Visit our Vickers replacement pumps applications guide.
