Product Selection Guide

These FluiDyne V20 Series single stage vane pumps differ mainly in flow rate, displacement, shaft configuration, rotation direction, and port orientation. All are direct Vickers replacement pumps, sharing SAE ‘A’ mounting and compatible port threads, but each model targets specific hydraulic needs such as higher flow, different rotation, or unique shaft types.

?? 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
WF8201651 (Current)	9.4 GPM	2500 PSI	29.7 cm³/r (1.81 in³/r)	2-Bolt Flange (SAE “A” size)
WF820169	13.5 GPM	2500 PSI	42.6 cm³/r (2.60 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201695	13.5 GPM	2500 PSI	42.6 cm³/r (2.60 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201639	5.7 GPM	2500 PSI	18.0 cm³/r (1.10 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201611	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 offer flow rates at 1200 RPM from 5.7 GPM (WF8201639) up to 13.5 GPM (WF820169, WF8201695), with corresponding displacement from 1.10 in³/r to 2.60 in³/r. For additional vane pump options, view our vane pumps lineup.

Selection Guide: Select lower flow models (WF8201639, WF8201611) for compact circuits and precise control, or higher flow models (WF820169, WF8201695) for faster actuator movement and larger hydraulic systems.

Rotation Direction

Difference: WF820169 is right-hand (clockwise), while WF8201695 is left-hand (counter-clockwise); others are right-hand.

Selection Guide: Match pump rotation to your system’s motor direction—choose WF8201695 if your drive requires counter-clockwise rotation.

Shaft Configuration

Difference: WF8201651 and WF820169 have an 11-tooth splined shaft; others use a 3/4″ straight keyed shaft. WF8201639 has a special shaft (code 18).

Selection Guide: Use splined shafts for higher torque applications or where splined couplings are standard; select straight keyed for simpler, lower-cost installations.

Maximum Speed & Pressure

Difference: All models are rated up to 2500 PSI. Maximum speed ranges from 2400 (WF820169, WF8201695) to 3400 RPM (WF8201611).

Selection Guide: Choose WF8201611 for applications with higher RPM requirements (up to 3400 RPM); others when operating at standard 1200 RPM.

Port Position

Difference: WF8201651 features a 90° port position; others have ports inline with the inlet (0°).

Selection Guide: Use 90° port models (WF8201651) in tight installations where straight port connections are challenging.

Quick Selection Guide

If you need: Lowest flow and finest control in a compact system

Choose: WF8201639

Because: Offers 5.7 GPM at 1200 RPM and 1.10 in³/r displacement, ideal for smaller actuators or precise hydraulic circuits.

If you need: Moderate flow with highest speed capability

Choose: WF8201611

Because: Provides 6.2 GPM at 1200 RPM, 1.19 in³/r displacement, and operates up to 3400 RPM for fast cycling applications.

If you need: Standard flow, splined shaft, and 90° port orientation

Choose: WF8201651

Because: Delivers 9.4 GPM at 1200 RPM, features an 11-tooth splined shaft, and 90° port for easier plumbing in confined spaces.

If you need: Maximum flow with standard (right-hand) rotation

Choose: WF820169

Because: Highest flow at 13.5 GPM and 2.60 in³/r displacement—best for large systems or rapid cylinder actuation.

If you need: Maximum flow with left-hand (counter-clockwise) rotation

Choose: WF8201695

Because: Identical high-flow performance as WF820169 but for systems requiring counter-clockwise pump rotation.

Compatibility: All models are 100% interchangeable with Vickers V20 Series, share SAE J744 ‘A’ 2-bolt flange mounting, and offer G1″/G1/2″ BSPP ports for straightforward installation. For similar application requirements, consider the V201P13P3C11R FluiDyne V20 Pump.
