Product Selection Guide

These single stage vane pumps from FluiDyne V20 Series are all direct Vickers replacements with 100% interchangeability, but differ in flow rate, displacement, pressure rating, shaft style, port type, and port orientation. Choosing the right model depends on your system’s flow and pressure needs, port connection requirements, and available space for installation. For more options, view our full range of vane pumps and hydraulic pumps.

?? 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.

Key Differences

Flow Rate & Displacement

Difference: WF820023 delivers 9.4 GPM (1.81 in³/r), WF820025 provides 11.5 GPM (2.22 in³/r), WF820026/WF8201811/WF8201212 offer 13.5 GPM (2.60 in³/r) at 1200 RPM.

Selection Guide: Select WF820023 for lower flow circuits or smaller actuators; WF820025 for mid-range flow; WF820026, WF8201811, or WF8201212 for higher flow demands.

Maximum Pressure & Speed

Difference: WF820023, WF820025, and WF820026 support up to 2500 PSI and vary in max speed (WF820023: 2800 RPM; WF820025: 2500 RPM; WF820026: 2400 RPM). Higher displacement models (WF820026, WF8201811, WF8201212) have slightly lower max speeds.

Selection Guide: Choose WF820023 for applications needing higher RPMs; WF820025/26/1811/1212 for standard speed and pressure.

Shaft Configuration

Difference: WF820025 and WF820026 use an 11-tooth splined shaft (1.25″ extension); WF820023, WF8201811, and WF8201212 use a 3/4″ straight shaft with key (varying extension), while WF8201212 also lists a 7/8″ threaded shaft with Woodruff key.

Selection Guide: Pick splined shafts (WF820025/26) for high-torque or splined couplings; choose straight keyed or threaded shafts for standard or legacy connections.

Port Type & Orientation

Difference: WF820025, WF820023, and WF820026 have SAE straight thread ports (1-5/8″-12 inlet, 1-1/16″-12 outlet). WF8201811 and WF8201212 feature NPT ports (1-1/4″ NPT inlet, 3/4″ NPT outlet). Port positions also vary: some are inline (0°), others opposite (180°).

Selection Guide: Select SAE ports for systems using straight thread adapters; NPT ports for pipe thread plumbing. Inline (0°) ports simplify straight plumbing, while 180° aids in tight layouts.

Model Number Patterns

Difference: Higher model numbers (e.g., WF820026 vs WF820023) correspond to higher displacement/flow. Models ending in ’11’ (e.g., WF8201811, WF8201212) commonly have NPT ports and alternate shaft types.

Selection Guide: Scan the last digits: ’11’ often signals NPT configurations or special shaft features; lower numbers are standard SAE/straight thread.

Quick Selection Guide

If you need: Lowest flow, highest RPM (smaller cylinders/motors, faster cycling)

Choose: WF820023

Because: 9.4 GPM, 1.81 in³/r displacement, and up to 2800 RPM for compact or high-speed hydraulic circuits.

If you need: Mid-range flow, standard SAE ports, and splined shaft for higher torque

Choose: WF820025

Because: 11.5 GPM, 2.22 in³/r, SAE straight thread, and 11-tooth splined shaft for robust industrial duties.

If you need: Maximum flow, SAE ports, and splined shaft

Choose: WF820026

Because: 13.5 GPM, 2.60 in³/r, suited for large actuators or high-output systems with standard SAE connections.

If you need: Maximum flow, NPT ports, and standard straight/keyed or threaded shaft

Choose: WF8201811 or WF8201212

Because: 13.5 GPM, 2.60 in³/r, NPT ports for pipe thread plumbing, and shaft options for legacy or special couplings.

Compatibility: All models directly replace Vickers replacement pumps applications, follow SAE J744 ‘A’ 2-bolt flange standards, and offer 100% interchangeability for mounting and performance.
