Key Differences
Total Flow Rate
Difference: WF8251002 delivers 21.0 GPM, WF8251091 offers 17.0 GPM, WF8251074 provides 18.0 GPM, WF8251014 and WF8251052 each supply 14.0 GPM.
Selection Guide: Pick WF8251002 for the highest combined flow, ideal for systems needing greater hydraulic output from a single pump.
Maximum Speed
Difference: WF8251002: 2400 RPM, WF8251091: 2500 RPM, WF8251074: 2500 RPM, WF8251014 and WF8251052: 1800 RPM (limited by rear pump).
Selection Guide: Select WF8251091 or WF8251074 for higher speed applications; WF8251014 and WF8251052 suit lower-speed, quieter systems.
Pump Rotation
Difference: WF8251002, WF8251074, WF8251014 are Left-Hand (CCW); WF8251091, WF8251052 are Right-Hand (CW).
Selection Guide: Choose rotation to match your prime mover—most electric motors require Right-Hand (CW); hydraulic motors may require Left-Hand (CCW).
Outlet Port Orientation
Difference: WF8251002: Front outlet opposite (180°), rear inline (0°). WF8251091: Front 90° CCW, rear opposite (180°). WF8251074: Both outlets inline with inlet (0°). WF8251014: Both outlets opposite inlet (180°). WF8251052: Both outlets inline with inlet (0°).
Selection Guide: Select port orientation based on hose routing—inline for straightforward plumbing, 180° or 90° for confined spaces or specific manifold layouts.
Shaft Type
Difference: WF8251002, WF8251091, WF8251014, WF8251052: Straight keyed shaft; WF8251074: 13-tooth splined shaft.
Selection Guide: Choose splined shaft (WF8251074) for higher torque or where compact, backlash-free coupling is needed; straight keyed shafts suit standard couplings.
Design Series & Mounting
Difference: All are Design Series 30, SAE ‘B’ 4-bolt flange.
Selection Guide: No difference here—all models are fully compatible with standard SAE J744 ‘B’ mounts.
Quick Selection Guide
If you need: Highest total flow (21.0 GPM), left-hand rotation, and mixed port orientation
Choose: WF8251002
Because: Delivers the most combined flow—ideal for high-demand systems with a left-hand rotating driver.
If you need: Higher speed operation (up to 2500 RPM) with right-hand rotation and 90° port for tight front connections
Choose: WF8251091
Because: Supports faster drive speeds and right-hand rotation with a unique 90° front outlet for flexible plumbing.
If you need: High speed with left-hand rotation and splined shaft for high-torque drive
Choose: WF8251074
Because: Offers a splined shaft plus inline ports—excellent for high-torque, compact coupling applications.
If you need: Lower total flow (14.0 GPM), left-hand rotation, both outlets opposite inlet
Choose: WF8251014
Because: Suited for compact systems with lower flow and specific port orientation needs at lower speeds.
If you need: Lower flow, right-hand rotation, and inline ports for simplified plumbing at lower speeds
Choose: WF8251052
Because: Best for right-hand driven applications with straightforward hose routing and moderate flow needs.
Compatibility: All models are direct replacements for Vickers V2020 double pumps, with SAE ‘B’ 4-bolt flanges and UN/BSPP straight thread ports for seamless interchangeability. For single-stage options, view our single stage vane pumps applications lineup.
