WUD1101B is best understood by its configuration rather than by the series name alone. This Enerpac Workholding Electric Hydraulic Pump is set up for single-acting advance / auto-retract operation. The 1.0 gal reservoir is at the larger end of this series, providing more available oil volume than the smaller-reservoir variants.
For smaller workholding systems, the WU economy design emphasizes portability while retaining two-speed hydraulic operation. This pump carries a 1.0 gal reservoir. That capacity is a practical selection factor when comparing otherwise similar valve and voltage configurations. The hydraulic performance point for this model is 25 in³/min @ 5,000 psi, paired with a 0.5 hp motor.
Understanding the WUD1101B Arrangement
The closest same-series alternative is WUD1100B. The useful difference is that reservoir capacity is 1.0 gal on WUD1101B versus 0.5 gal on WUD1100B. Choose between them from the circuit and site requirements rather than from appearance.
Check the hydraulic system's total oil demand against the 1.0 gal reservoir before final selection.
