Product Selection Guide

These FluiDyne V20 Series hydraulic vane pumps are direct replacements for Vickers replacement pumps, sharing SAE ‘A’ mounting and G1″/G1/2″ BSPP ports. They differ mainly in flow rate, displacement, shaft configuration, rotation, and port positions—allowing you to match your system’s exact needs for speed, space, and connection style. For applications requiring efficient and robust single stage solutions, see our single stage vane pumps category.

?? 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
WF8202566 (Current)	12.5 GPM	2500 PSI	39.5 cm³/r (2.41 in³/r)	2-Bolt Flange (SAE “A” size)
WF8202573	13.5 GPM	2500 PSI	42.6 cm³/r (2.60 in³/r)	2-Bolt Flange (SAE “A” size)
WF8202583	13.5 GPM	2500 PSI	42.6 cm³/r (2.60 in³/r)	2-Bolt Flange (SAE “A” size)
WF8202557	5.7 GPM	2500 PSI	18.0 cm³/r (1.10 in³/r)	2-Bolt Flange (SAE “A” size)
WF8202538	6.2 GPM	2500 PSI	19.5 cm³/r (1.19 in³/r)	2-Bolt Flange (SAE “A” size)

Key Differences

Flow Rate

Difference: Models range from 5.7 GPM (WF8202557) to 13.5 GPM (WF8202573, WF8202583) at 1200 RPM

Selection Guide: Select a model with a flow rate that matches your system’s actuator size and speed requirements—higher GPM for faster or larger cylinders/motors.

Displacement

Difference: Displacement increases by model: 1.10 in³/r (WF8202557), 1.19 in³/r (WF8202538), 2.41 in³/r (WF8202566), 2.60 in³/r (WF8202573/WF8202583)

Selection Guide: Choose a displacement that delivers your required flow at your system’s operating speed.

Rotation Direction

Difference: WF8202583 is right-hand (clockwise), others are left-hand (counter-clockwise)

Selection Guide: Match pump rotation to your drive—incorrect rotation can cause pump failure.

Shaft Configuration

Difference: Options include 3/4″ straight keyed shaft (most models), 9-tooth splined shaft (WF8202573/WF8202583), and special shaft codes (WF8202566, WF8202538)

Selection Guide: Select the shaft type that fits your coupling and torque needs—splined shafts suit high-torque, keyed shafts are standard.

Port Position

Difference: Inline ports (WF8202566, WF8202583, WF8202538), 90° counter-clockwise (WF8202573), 90° clockwise (WF8202557)

Selection Guide: Choose inline for straight plumbing runs, 90° orientation for installations with space restrictions or preferred hose routing.

Max Speed

Difference: WF8202557 and WF8202538 rated up to 3000 RPM, others up to 2400 RPM

Selection Guide: For higher-speed drives, select models rated up to 3000 RPM.

Quick Selection Guide

If you need: Lowest flow and displacement for compact, low-demand systems

Choose: WF8202557 (5.7 GPM, 1.10 in³/r)

Because: Ideal for small actuators or limited system flow

If you need: Moderate flow for mid-sized equipment

Choose: WF8202538 (6.2 GPM, 1.19 in³/r) or WF8202566 (12.5 GPM, 2.41 in³/r)

Because: Covers a range of typical industrial and mobile hydraulics

If you need: Maximum flow and displacement for large or fast actuators

Choose: WF8202573 or WF8202583 (13.5 GPM, 2.60 in³/r)

Because: Best for systems requiring rapid movement or high-volume circuits

If you need: Right-hand (clockwise) rotation for specific drive requirements

Choose: WF8202583

Because: Only model in this group with right-hand rotation

If you need: Splined shaft for high torque or specific couplings

Choose: WF8202573 or WF8202583

Because: Feature a 9-tooth splined shaft (1.25″ extension)

If you need: Ports at 90° for tight installations

Choose: WF8202573 (90° counter-clockwise), WF8202557 (90° clockwise)

Because: Allows flexible hose routing in space-constrained layouts

If you need: Inline ports for straight-through plumbing

Choose: WF8202566, WF8202583, or WF8202538

Because: Simplifies installation in open layouts

Compatibility: All models are 100% interchangeable with Vickers V20 pumps, use SAE J744 ‘A’ 2-bolt flange mounting, and G1″/G1/2″ BSPP threaded ports for simple retrofit or replacement.
