Product Selection Guide

These FluiDyne V20 Series hydraulic vane pump models differ primarily in flow rate (GPM), displacement (in³/rev), shaft type, rotation direction, port orientation, and port connection type. All are direct Vickers replacements, with SAE ‘A’ 2-bolt flange mounting and are fully compatible with Vickers V20 series. Key selection factors include required flow, shaft compatibility, rotation, and port arrangement for your plumbing—for technical guides, consult our vane pump specifications.

?? 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
WF820573 (Current)	9.4 GPM	2500 PSI	29.7 cm³/r (1.81 in³/r)	2-Bolt Flange (SAE “A” size)
WF820572	6.2 GPM	2500 PSI	19.5 cm³/r (1.19 in³/r)	2-Bolt Flange (SAE “A” size)
WF820578	6.2 GPM	2500 PSI	19.5 cm³/r (1.19 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: WF820572 and WF820578 deliver 6.2 GPM (1.19 in³/rev); WF820573 provides 9.4 GPM (1.81 in³/rev); WF8201811 and WF8201212 offer 13.5 GPM (2.60 in³/rev).

Selection Guide: Select lower displacements (WF820572, WF820578) for compact systems or precise flow needs; choose higher (WF8201811, WF8201212) for demanding circuits or larger actuators.

Rotation Direction

Difference: WF820572 and WF820573 are left-hand (counter-clockwise); WF820578, WF8201811, and WF8201212 are right-hand (clockwise).

Selection Guide: Match pump rotation to your drive motor; incorrect rotation can cause damage.

Port Position

Difference: WF820572, WF820573, and WF8201212 have ports opposite each other (180°); WF820578 and WF8201811 have inline ports (0°).

Selection Guide: Choose 180° ports for traditional hose routing; 0° inline ports simplify straight-line plumbing or accommodate tight spaces.

Shaft Type and Size

Difference: WF820572, WF820573, WF820578, and WF8201811 use a 3/4″ straight keyed shaft; WF8201212 features a 7/8″ threaded shaft with Woodruff key.

Selection Guide: Verify shaft compatibility with your coupling. Threaded shafts (WF8201212) fit specific drive setups or retrofits.

Max Pressure & Speed

Difference: WF820572, WF820573, WF820578: 2500 PSI, up to 3400 RPM (for 6.2 GPM models); WF8201811 and WF8201212: 2200 PSI max, 2400 RPM (for 13.5 GPM models).

Selection Guide: For high-pressure, high-speed needs at moderate flow, use 6.2 or 9.4 GPM models. For higher flows at slightly lower pressure, use 13.5 GPM models.

Port Connection Type

Difference: WF820572, WF820573, WF8201811, WF8201212: 1-1/4″ NPT inlet, 3/4″ NPT outlet; WF820578: 1-5/8″-12 straight thread inlet, 3/4″ NPT outlet.

Selection Guide: Choose NPT for standard U.S. plumbing; select straight thread (WF820578) if matching to metric or specialized fittings.

Quick Selection Guide

If you need: Lowest flow and displacement, left-hand rotation, NPT ports, standard keyed shaft

Choose: WF820572

Because: Ideal for precise, compact systems requiring 6.2 GPM at 2500 PSI with traditional plumbing and left-hand drive.

If you need: Moderate flow and displacement, left-hand rotation, NPT ports, standard keyed shaft

Choose: WF820573

Because: Offers 9.4 GPM for mid-sized circuits, maintaining left-hand rotation and easy integration.

If you need: Low flow with right-hand rotation, inline ports, straight thread inlet

Choose: WF820578

Because: Best for compact, right-hand drive applications where straight thread fitting and inline plumbing are preferred.

If you need: Maximum flow, right-hand rotation, standard keyed shaft, inline ports

Choose: WF8201811

Because: 13.5 GPM suits large actuators or high-output circuits, with right-hand rotation and inline plumbing.

If you need: Maximum flow, right-hand rotation, threaded shaft, ports opposite

Choose: WF8201212

Because: 13.5 GPM for large systems, compatible with drive systems needing a 7/8″ threaded shaft and 180° ports.

Compatibility: All models are direct Vickers replacements, 100% interchangeable, and use SAE ‘A’ 2-bolt flanges. Ports are G1″/G1/2″ BSPP (straight thread) for easy global compatibility.
