Product Selection Guide

These Fluidyne V20 Series single stage vane pump models are all direct Vickers replacements with 100% interchangeability, sharing the same SAE ‘A’ 2-bolt flange mounting and BSPP port sizes. The primary differences are in flow rate, displacement, shaft configuration, port position, and maximum pressure. For a broader selection, browse our hydraulic pumps category. These factors influence which model is best suited for your system requirements, installation constraints, and connection 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
WF820035 (Current)	8.4 GPM	2500 PSI	26.6 cm³/r (1.62 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)
WF8201212	13.5 GPM	2500 PSI	42.6 cm³/r (2.60 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201138	13.5 GPM	2500 PSI	42.6 cm³/r (2.60 in³/r)	2-Bolt Flange (SAE “A” size)
WF8202442	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: WF820035 delivers 8.4 GPM (1.62 in³/rev), while WF8201811, WF8201212, WF8201138, and WF8202442 deliver 13.5 GPM (2.60 in³/rev)

Selection Guide: Choose WF820035 for lower-flow applications or when precise, smaller displacement is needed; select any of the 13.5 GPM models when higher flow is required

Maximum Pressure

Difference: WF820035 supports up to 2500 PSI; other models are rated at 2200 PSI (description) but show 2500 PSI in detailed specs—verify system requirements

Selection Guide: If your system regularly operates near 2500 PSI, confirm the actual rating before selection; WF820035 is safest for highest pressure

Shaft Type & Extension

Difference: WF820035 uses a 3/4″ straight keyed shaft (2.66″ extension); WF8201811, WF8201212, WF8201138, and WF8202442 use 3/4″ straight keyed shafts (1.75″ extension) or 7/8″ threaded shafts with Woodruff key

Selection Guide: Choose shaft type/extension to match your coupling style and torque needs—straight keyed for most standard applications, threaded for specific drive couplings

Port Position

Difference: WF820035 and WF8201212: ports opposite (180°); WF8201811, WF8201138, WF8202442: ports inline (0°)

Selection Guide: Choose inline ports for straight plumbing runs; use 180° ports for opposing connection layouts

Port Thread Type

Difference: WF820035: 1-5/8″-12 & 1-1/16″-12 straight thread; other models: 1-1/4″ NPT & 3/4″ NPT (description) or G1″/G1/2″ BSPP (detailed spec)

Selection Guide: Verify port thread type to match your fittings—select the model with ports compatible with your existing hoses or adapters

Shaft Configuration (Special Codes)

Difference: WF8201811 (Code 39) and WF8202442 (Code 40) have special shaft configurations, which may be required for certain OEM drive setups

Selection Guide: If your equipment specifies a shaft code, match accordingly

Quick Selection Guide

If you need: Lower flow, highest pressure (8.4 GPM at up to 2500 PSI)

Choose: WF820035

Because: It offers the smallest displacement and full 2500 PSI rating, ideal for precision or lower-volume circuits

If you need: Higher flow (13.5 GPM) with standard shaft and inline ports

Choose: WF8201811 or WF8202442

Because: Both provide higher displacement and inline ports for straightforward plumbing

If you need: undefined

Choose: WF8201212

Because: It offers 13.5 GPM, opposite port orientation, and a threaded shaft for specific coupling requirements

If you need: Special shaft configuration or OEM replacement

Choose: WF8201811 (Code 39) or WF8202442 (Code 40)

Because: These models match special OEM shaft specifications

Compatibility: All models are direct replacements for Vickers replacement pumps, fully interchangeable with SAE ‘A’ 2-bolt flanges and G1″/G1/2″ BSPP ports, ensuring drop-in compatibility.
