Product Selection Guide

These Fluidyne V20 Series hydraulic vane pumps are all direct Vickers replacements, sharing the same SAE ‘A’ mounting and general port sizes, but differ in flow rate, displacement, port orientation, shaft configuration, rotation, and inlet/outlet thread types. These variances let you match the pump exactly to your flow, speed, and installation requirements.

?? Important: The specifications shown are for reference and comparison purposes. Always verify specifications with the official manufacturer documentation or consult our hydraulic pumps knowledge center, 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
WF8201787 (Current)	6.2 GPM	2500 PSI	19.5 cm³/r (1.19 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201742	13.5 GPM	2500 PSI	42.6 cm³/r (2.60 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201739	13.5 GPM	2500 PSI	42.6 cm³/r (2.60 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201780	6.2 GPM	2500 PSI	19.5 cm³/r (1.19 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201762	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: WF8201787 and WF8201780 deliver 6.2 GPM at 1.19 in³/rev; for slightly lower displacement, consider the V201P5P18C11R – FluiDyne V20 Pump. WF8201762 provides 7 GPM (displacement not explicitly specified but likely higher); WF8201742 and WF8201739 deliver 13.5 GPM at 2.60 in³/rev.

Selection Guide: Select WF8201742 or WF8201739 for systems needing higher flow (up to 13.5 GPM), WF8201787 or WF8201780 for moderate flows, and WF8201762 for slightly higher than standard 6 GPM applications.

Rotation Direction

Difference: WF8201787, WF8201780, and WF8201739 are right-hand (clockwise); WF8201742 and WF8201762 are left-hand (counter-clockwise).

Selection Guide: Choose the rotation that matches your drive motor or system design—critical for compatibility and performance.

Port Orientation

Difference: WF8201787: Ports 180° opposed; WF8201742 & WF8201780 & WF8201762: Ports inline (0°); WF8201739: Ports at 90° clockwise.

Selection Guide: Use inline or 180° for straight-through plumbing; 90° configurations (WF8201739) help in tight or angled mounting situations.

Inlet/Outlet Thread Type & Size

Difference: WF8201787: 1″ NPT inlet, 3/4″ NPT outlet; WF8201742: 1-1/4″ NPT inlet, 3/4″ NPT outlet; WF8201739 & WF8201780: 1-1/4″ NPT inlet, 1-1/16″-12 outlet; WF8201762: 1-1/4″ NPT inlet, 3/4″ NPT outlet.

Selection Guide: Match inlet/outlet sizes to your hose or pipework to minimize restriction and ensure proper fit.

Shaft Configuration

Difference: Most use a 3/4″ straight keyed shaft (extension varies: 1.75″ or 2.66″); WF8201762 has a special shaft (Code 15).

Selection Guide: Ensure the shaft matches your coupling or drive—verify length and key configuration for drop-in replacement.

Maximum Speed

Difference: WF8201787 and WF8201780 rated for 3400 RPM; WF8201742 and WF8201739 for 2400 RPM; WF8201762 for 3000 RPM.

Selection Guide: Choose higher-rated speed pumps for faster cycling or applications with high input RPM.

Quick Selection Guide

If you need: High flow at 1200 RPM (13.5 GPM)

Choose: WF8201742 (left-hand, inline ports, 1-1/4″ NPT inlet, 3/4″ NPT outlet) or WF8201739 (right-hand, 90° ports, 1-1/4″ NPT inlet, 1-1/16″-12 outlet)

Because: Best suited for circuits with larger actuators or higher speed requirements.

If you need: Compact flow (6.2 GPM) at high speed (up to 3400 RPM)

Choose: WF8201787 (right-hand, 180° ports, 1″ NPT inlet, 3/4″ NPT outlet) or WF8201780 (right-hand, inline ports, 1-1/4″ NPT inlet, 1-1/16″-12 outlet)

Because: Ideal for smaller or medium-sized hydraulic circuits and high RPM drive sources.

If you need: Slightly higher flow than standard 6 GPM but not full 13.5 GPM

Choose: WF8201762 (left-hand, inline ports, 1-1/4″ NPT inlet, 3/4″ NPT outlet, special shaft)

Because: Fills the gap for mid-sized systems or where shaft configuration is critical.

If you need: Specific port orientation for tight spaces

Choose: WF8201739 (90° port orientation)

Because: Allows easier plumbing in confined or uniquely oriented installations.

Compatibility: All models feature SAE J744 ‘A’ 2-bolt flange mounting and G1″/G1/2″ BSPP straight thread ports, ensuring 100% interchangeability with Vickers pumps and rapid installation.
