Product Selection Guide
These FluiDyne V2020 double vane pumps differ mainly by their individual front and rear pump flow rates, total combined flow, port orientation, maximum speed, mounting flange type, and shaft style. See all pumps with integral valves for specialized system needs. Each model is a direct, 100% interchangeable replacement for Vickers V2020 double vane pumps, and all meet SAE J744 mounting standards.
?? 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
Front & Rear Pump Flow Rates
Difference: Front pump flow ranges from 6 to 13 GPM, rear pump from 6 to 7 GPM. Total flow varies from 12 to 20 GPM.
Selection Guide: Select higher flow models (e.g., WF825125) for systems needing more combined hydraulic flow, and balanced-flow models (e.g., WF825124) for twin or parallel circuits.
Maximum Speed
Difference: Max speed is limited by the front pump: up to 3400 RPM (WF825127), 3000 RPM (WF825121), 2800 RPM (WF825124, WF825129), and 2400 RPM (WF825125).
Selection Guide: Choose higher speed models (e.g., WF825127 at 3400 RPM) for fast-cycling or high-RPM drives.
Port Orientation
Difference: WF825121 has both outlets 90° CW from inlet; WF825124 is 180° opposite inlet; WF825125, WF825127, and WF825129 are inline (0°) with inlet.
Selection Guide: Pick inline outlet models for straightforward plumbing, or 90°/180° for space-constrained or custom layouts.
Shaft Style
Difference: WF825121, WF825124, WF825125 have straight keyed shafts; WF825127 and WF825129 feature 13-tooth splined shafts.
Selection Guide: Select splined shafts for higher-torque or coupling flexibility, keyed shafts for standard replacements.
Mounting Flange
Difference: WF825121, WF825124, WF825125, WF825127 use SAE ‘B’ 4-bolt flanges; WF825129 uses SAE ‘A’ 2-bolt flange.
Selection Guide: Choose based on your equipment’s mounting requirements—ensure flange compatibility.
Total Displacement
Difference: Varies from 2.38 cu.in./rev (WF825127) to 4.00 cu.in./rev (WF825125).
Selection Guide: Select higher displacement for greater per-rev fluid transfer, useful for larger actuators.
Quick Selection Guide
If you need: Balanced, moderate flow (7+7 GPM) at up to 3000 RPM
Choose: WF825121
Because: Provides 14 GPM total, 90° outlet orientation, and high speed capacity—ideal for synchronized circuits.
If you need: Maximum total flow (20 GPM) with high front section output
Choose: WF825125
Because: Delivers 13 GPM front/7 GPM rear, matching applications demanding high primary and auxiliary flows.
If you need: Lower, balanced flow with highest RPM capability
Choose: WF825127
Because: Both sections offer 6 GPM at up to 3400 RPM; features splined shaft for high-torque drive compatibility.
If you need: Higher, balanced flow (8+8 GPM) and opposite port orientation
Choose: WF825124
Because: 16 GPM total and 180° port layout simplifies specific machine installations.
If you need: Unbalanced flow with splined shaft and SAE ‘A’ mounting
Choose: WF825129
Because: 9 GPM front/7 GPM rear, 16 GPM total, SAE ‘A’ 2-bolt flange, and splined shaft suits compact, high-torque drives.
Compatibility: All models are 100% interchangeable with Vickers V2020 double vane pumps, feature SAE-conforming flanges, and use G1″/G1/2″ BSPP straight-thread ports for straightforward replacement.
