Important: Verify pump model WF8251115 matches your existing Vickers unit before ordering. For a full range of hydraulic pumps, explore our product family. For technical assistance or to confirm interchangeability, contact (800) 823-4937.

Product Selection Guide

The provided FluiDyne V2020 double vane pump models (see single stage vane pumps for comparison) differ primarily in their total flow rates, front/rear pump GPM combinations, port orientations, shaft types, rotation direction, and allowable maximum speeds. These differences directly impact system performance, installation layout, and compatibility with existing hydraulic circuits.

?? 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
WF8251115 (Current)	12	2500 PSI	19.5 cm³/r (1.19 in³/r)	2-Bolt Flange (SAE “A” size)
WF8251121	10	2500 PSI	19.5 cm³/r (1.19 in³/r)	2-Bolt Flange (SAE “A” size)
WF825111	11	2500 PSI	19.5 cm³/r (1.19 in³/r)	2-Bolt Flange (SAE “A” size)
WF825115	11	2500 PSI	19.5 cm³/r (1.19 in³/r)	2-Bolt Flange (SAE “A” size)

Key Differences

Total Flow Rate

Difference: WF8251115 delivers the highest total flow at 20.0 GPM, followed by WF825116 at 19.0 GPM, WF8251121 at 15.0 GPM, and WF825111/WF825115 at 12.0 GPM.

Selection Guide: Select WF8251115 or WF825116 for systems needing higher combined pump flows; WF825111 or WF825115 for lower flow or more precise control.

Front/Rear Pump Output

Difference: WF8251115 offers 12 GPM (front) + 8 GPM (rear); WF825116: 11 GPM + 8 GPM; WF8251121: 10 GPM + 5 GPM; WF825111/WF825115: 11 GPM + 1 GPM.

Selection Guide: Choose models with higher rear GPM (WF8251115, WF825116) for dual-circuit or Hi-Lo applications needing more secondary flow. For different displacement needs, see V201P13P3C11R – FluiDyne V20 Pump.

Maximum Speed

Difference: WF825116 allows up to 2500 RPM; WF8251115 up to 2400 RPM; WF8251121, WF825111, and WF825115 limited to 1800 RPM.

Selection Guide: Select WF825116 for higher-speed applications; for 18.0 cm³/r options, see V201P5P18C11R – FluiDyne V20 Pump. Avoid WF8251121, WF825111, and WF825115 if your drive runs above 1800 RPM.

Port Orientation

Difference: WF8251115 and WF825111: both outlets opposite inlet (180°); WF8251121: front 180°, rear inline (0°); WF825115: both 90° CW from inlet; WF825116: both 90° CCW from inlet.

Selection Guide: Choose port orientation based on your plumbing layout—180° for straight runs, 90° for compact or side-exit connections. Explore pumps with integral valves for specialized configurations.

Rotation Direction

Difference: WF8251115, WF8251121, WF825111: Left-Hand (CCW); WF825115, WF825116: Right-Hand (CW).

Selection Guide: Match rotation to your drive—left-hand for CCW motors, right-hand for CW.

Shaft Type

Difference: WF8251115, WF8251121: Straight Keyed Shaft; WF825111, WF825115: 13-Tooth Splined Shaft; WF825116: Shaft code 51 (type not further specified).

Selection Guide: Use straight keyed shafts for standard couplings; select splined for higher torque or specialized couplings.

Quick Selection Guide

If you need: Highest total flow (20.0 GPM), left-hand rotation, and both outlets opposite inlet

Choose: WF8251115

Because: It maximizes dual-circuit output and fits standard 180° plumbing with a straight keyed shaft.

If you need: High flow (19.0 GPM), right-hand rotation, and 90° CCW outlet ports

Choose: WF825116

Because: It supports higher speeds and 90° porting for compact installation.

If you need: Moderate flow (15.0 GPM), left-hand rotation, with mixed port orientation

Choose: WF8251121

Because: It offers a dual-circuit split with flexible plumbing for specific system layouts.

If you need: Low rear section flow (1 GPM), left-hand rotation, and 180° porting

Choose: WF825111

Because: Ideal for applications with minimal secondary circuit requirements. For alternative flow profiles, see similar applications in other double vane series.

If you need: Low rear section flow (1 GPM), right-hand rotation, and 90° CW porting

Choose: WF825115

Because: Best for low secondary flow needs and right-hand drive motors in tight installations.

Compatibility: All models use SAE ‘B’ 4-bolt flange mounting and 1-1/16″-12 UN-2B thread outlets for direct Vickers replacement pumps interchangeability. They meet SAE J744 standards and accept G1″/G1/2″ BSPP ports for straightforward replacement.
