Product Selection Guide

These FluiDyne V2020 double vane pumps are all direct Vickers replacements, fully SAE J744 compatible, and share key specs like 2500 PSI pressure rating, 2-bolt SAE ‘A’ flange mounting, and G1″/G1/2″ BSPP ports. The critical differences are in flow rates, rear pump outputs, maximum speeds, shaft types, rotation, and port orientation—each impacting suitability for specific hydraulic system layouts and flow requirements.

?? 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

Total Flow Rate

Difference: WF8251091 and WF8251074 provide the highest total flows (17.0 GPM and 18.0 GPM, respectively), while WF8251014 and WF8251052 offer lower total flows (14.0 GPM). WF8251051 delivers 13.0 GPM with no rear pump flow.

Selection Guide: Select WF8251091 or WF8251074 for higher combined flow needs; WF8251051, WF8251014, and WF8251052 are better for lower flow or single-section applications. For alternate flow specs, see comparable FluiDyne V20 Pump models.

Rear Pump Output

Difference: WF8251051 has a rear pump with 0 GPM (effectively single-section); WF8251091 (6 GPM) and WF8251074 (7 GPM) offer significant rear pump flows; WF8251014 and WF8251052 provide 2 GPM rear outputs.

Selection Guide: Choose WF8251074 or WF8251091 if your application benefits from dual flows (e.g., Hi-Lo circuits); select WF8251051 for single-circuit needs.

Maximum Speed

Difference: WF8251091 and WF8251074 allow higher speeds (up to 2500 RPM), while WF8251051, WF8251014, and WF8251052 are limited to 1800 RPM by their rear section.

Selection Guide: For high-speed drive sources or faster cycling, WF8251091 or WF8251074 are preferred. For systems with lower drive speeds, any model is suitable.

Shaft Type

Difference: WF8251051 and WF8251074 use a 13-tooth splined shaft; WF8251091, WF8251014, and WF8251052 use a 3/4″ straight keyed shaft.

Selection Guide: Select splined shaft models for higher torque or when splined couplings are required; straight keyed shafts suit standard couplings.

Rotation

Difference: WF8251051, WF8251074, and WF8251014 are left-hand (counter-clockwise); WF8251091 and WF8251052 are right-hand (clockwise).

Selection Guide: Match rotation to your motor/drive direction: use left-hand for CCW drive, right-hand for CW.

Port Orientation

Difference: WF8251051, WF8251074, and WF8251052 have both outlets inline with the inlet (0°); WF8251014 has both outlets opposite the inlet (180°); WF8251091 has front outlet at 90° CCW, rear at 180°.

Selection Guide: Choose 0° orientation for straight-line plumbing; 90° or 180° for tight or specific layout requirements.

Quick Selection Guide

If you need: Highest total flow and dual-section output (Hi-Lo circuits)

Choose: WF8251074 (18.0 GPM, 11 GPM front/7 GPM rear, 2500 RPM, left-hand, splined shaft)

Because: Delivers the greatest output and supports high-speed operation.

If you need: High dual flows with right-hand rotation

Choose: WF8251091 (17.0 GPM, 11 GPM front/6 GPM rear, 2500 RPM, right-hand, straight shaft)

Because: Best for systems requiring clockwise rotation and dual-circuit design.

If you need: Single-section flow or minimal rear output

Choose: WF8251051 (13.0 GPM, 0 GPM rear, 1800 RPM, left-hand, splined shaft)

Because: Ideal for applications needing only one circuit or minimal rear pump use.

If you need: Moderate dual flows at lower speeds, left-hand rotation

Choose: WF8251014 (12/2 GPM, 14.0 GPM total, 1800 RPM, left-hand, straight shaft, 180° ports)

Because: Suited for applications with low-speed drives and opposite port layouts.

If you need: Moderate dual flows at lower speeds, right-hand rotation

Choose: WF8251052 (12/2 GPM, 14.0 GPM total, 1800 RPM, right-hand, straight shaft, inline ports)

Because: Best for clockwise drives with inline plumbing.

Compatibility: All models are direct Vickers replacements, follow SAE J744 mounting, and use G1″/G1/2″ BSPP straight-thread ports, ensuring straightforward interchangeability with existing Vickers systems. For additional options, check our pumps with integral valves category.
