Product Selection Guide

These FluiDyne V2020 double vane pumps are all direct Vickers replacements but differ in total flow rate, pump section configuration (single or double), rotation direction, port orientation, and shaft type. Selecting the right model depends on required system flow, direction of rotation, outlet orientation, and whether both pump sections are needed for your hydraulic circuit.

?? 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
WF825421 (Current)	9	2500 PSI	19.5 cm³/r (1.19 in³/r)	2-Bolt Flange (SAE “A” size)
WF825424	8	2500 PSI	19.5 cm³/r (1.19 in³/r)	2-Bolt Flange (SAE “A” size)
WF825423	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)

Key Differences

Total Flow Rate

Difference: WF825421 delivers 18.0 GPM (two 9 GPM sections), WF825424 and WF825423 deliver 16.0 GPM (two 8 GPM sections), while WF825975 and WF825063 provide 10.0 GPM (front section only, rear section not active). For details on the V20201F10S10S11AA30L series, see V20201F10S10S11AA30L – FluiDyne V2020.

Selection Guide: Choose WF825421 for highest total flow (18.0 GPM), WF825424 or WF825423 for moderate dual flows (16.0 GPM), and WF825975 or WF825063 for single-section or backup/auxiliary flow applications (10.0 GPM).

Rotation Direction

Difference: WF825421 and WF825975 are Left-Hand (Counter-Clockwise); WF825424, WF825423, and WF825063 are Right-Hand (Clockwise).

Selection Guide: Match rotation to your drive motor—select Left-Hand for CCW drives and Right-Hand for CW drives.

Port Orientation

Difference: WF825421 has both outlets 90° CCW from inlet; WF825424, WF825975, and WF825063 have both outlets opposite inlet (180°); WF825423 has front outlet inline (0°), rear outlet 90° CW.

Selection Guide: Choose 90° for side outlet applications, 180° for opposite-side piping, and mixed for custom layouts. WF825423 is best for systems needing different outlet orientations front/rear.

Shaft Type

Difference: WF825421, WF825424, WF825975, and WF825063 use a 13-Tooth Splined Shaft; WF825423 has a Straight Keyed Shaft.

Selection Guide: Use splined shafts for higher torque and better alignment in demanding drives; keyed shafts for standard, lower-torque couplings. For pumps with additional integrated features, explore pumps with integral valves.

Pump Configuration

Difference: WF825421, WF825424, and WF825423 have dual active sections (both front and rear pump), WF825975 and WF825063 only have an active front section (rear is inactive/0 GPM).

Selection Guide: Select dual-section models when you need Hi-Lo circuits or two different flows/pressures; single-section models for simpler systems or when only one output is required. For similar flow requirements, see the V201P5P18C11R – FluiDyne V20 Pump (18.0 cm³/r).

Quick Selection Guide

If you need: Maximum dual-section flow (18.0 GPM) and CCW rotation

Choose: WF825421

Because: Provides two 9 GPM sections, ideal for demanding circuits needing highest combined flow with left-hand rotation.

If you need: Moderate dual-section flow (16.0 GPM) with CW rotation and matching outlet orientation

Choose: WF825424

Because: Both outlets are opposite the inlet, simplifying opposite-side piping in clockwise systems.

If you need: Moderate dual-section flow (16.0 GPM) with CW rotation and mixed outlet positions

Choose: WF825423

Because: Front and rear outlets are positioned differently for custom piping layouts, with a straight keyed shaft for standard couplings.

If you need: Single-section flow (10.0 GPM) with CCW rotation

Choose: WF825975

Because: Only the front pump is active, suitable for applications needing a single output or for redundancy.

If you need: Single-section flow (10.0 GPM) with CW rotation

Choose: WF825063

Because: Only the front pump is active, suited to clockwise drives needing a compact, single-output solution.

Compatibility: All models are 100% interchangeable with Vickers equivalents, use SAE ‘A’ mounting, and share G1″/G1/2″ BSPP ports for straightforward retrofit or new design integration.
