Product Selection Guide

The FluiDyne V20 Series models WF820250, WF8202573, WF8202583, WF8202557, and WF8202538 all offer direct Vickers interchangeability, robust 2-bolt SAE ‘A’ mounting, and comparable pressure capabilities. Their main differences are in flow rate, displacement, shaft type, port sizes/orientation, and rotation direction, which impact system compatibility and performance. Selection should be based on required system flow, pressure, shaft/coupling compatibility, and hydraulic circuit design.

?? 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
WF820250 (Current)	9.4 GPM	2500 PSI	29.7 cm³/r (1.81 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 & Displacement

Difference: Models span from 5.7 GPM (1.10 in³/r) up to 13.5 GPM (2.60 in³/r) at 1200 RPM.

Selection Guide: Match flow rate and displacement to your actuator or circuit needs—select lower GPM/displacement for precise, low-volume tasks and higher for larger cylinders or faster cycle times.

Shaft Configuration & Size

Difference: WF820250 and WF8202557 use a 3/4″ straight keyed shaft (2.66″ extension), while WF8202573 and WF8202583 have a 9-tooth splined shaft (1.25″ extension). WF8202538 has a special shaft configuration.

Selection Guide: Use straight keyed shafts for standard couplings; opt for splined on WF8202573/2583 for higher torque or when vibration is a concern. Special shaft (WF8202538) fits unique couplings.

Port Size & Thread Type

Difference: Inlet ports are 1″ NPT (WF820250) or 1-1/4″ NPT (others); outlet ports vary: 3/4″ NPT or 1-1/16″-12 straight thread.

Selection Guide: Ensure port sizes/thread types match your plumbing; larger inlets reduce suction restriction for higher-flow models.

Port Position

Difference: WF820250: 180° (opposite inlet); WF8202573: 90° CCW; WF8202583: inline (0°); WF8202557: 90° CW; WF8202538: inline (0°).

Selection Guide: Select port orientation to ease hose routing—inline for straight connections, 90° for compact/tight layouts.

Rotation Direction

Difference: WF820250 and WF8202583 are right-hand (clockwise); WF8202573, WF8202557, WF8202538 are left-hand (counter-clockwise).

Selection Guide: Match rotation to your prime mover’s direction—incorrect rotation will cause pump failure.

Max Pressure & Speed

Difference: All models rated 2500 PSI; max speed varies: 2400–3000 RPM.

Selection Guide: For high-speed drives (up to 3000 RPM), choose WF8202557 or WF8202538.

Quick Selection Guide

If you need: Standard flow, right-hand rotation, and basic plumbing compatibility

Choose: WF820250

Because: Offers 9.4 GPM, 1″ NPT inlet, 3/4″ NPT outlet, and right-hand rotation for general-purpose replacements.

If you need: Higher flow and left-hand rotation with splined shaft

Choose: WF8202573

Because: Provides 13.5 GPM, 9-tooth splined shaft, 1-1/4″ NPT inlet, and 90° CCW porting for high-volume, high-torque, or reverse-rotation systems.

If you need: High flow and right-hand rotation with splined shaft

Choose: WF8202583

Because: 13.5 GPM, 1-1/4″ NPT inlet, 1-1/16″-12 outlet, 9-tooth splined shaft, and inline porting suit right-hand, high-flow applications needing robust coupling.

If you need: Low flow, max speed, and left-hand rotation

Choose: WF8202557

Because: 5.7 GPM and up to 3000 RPM rating—ideal for precision/low-volume circuits on high-speed drives.

If you need: Mid-range flow, left-hand rotation, and special shaft

Choose: WF8202538

Because: 6.2 GPM, up to 3000 RPM, inline porting, and unique shaft configuration for special coupling requirements.

Compatibility: All models are 100% Vickers-interchangeable, use SAE J744 ‘A’ 2-bolt flanges, and support G1″/G1/2″ BSPP ports for flexible installation. For pumps with integrated control options, see our pumps with integral valves selection. All pumps are covered by a 12-month manufacturer warranty and qualify for volume discounts starting at 4 units. Same-day shipping is available for in-stock items.

For model selection, cross-referencing, or troubleshooting, hydraulic specialists are available Mon-Fri, 7 AM – 5 PM MST at (800) 823-4937. For proven field applications, see our case studies with V20 series in similar use cases.
