PUD1301B occupies a distinct point in the Enerpac Economy Electric Hydraulic Pump family because of its single-acting advance / hold / retract operation configuration. For a single-acting circuit, the hold function separates this model from simple dump-style pumps by allowing hydraulic pressure to be maintained between advance and return.
Before Specifying PUD1301B
To avoid selecting a near-match with the wrong configuration, compare PUD1301B with PUD1300B: reservoir capacity is 1.0 gal on PUD1301B versus 0.5 gal on PUD1300B.
PUD pumps combine the portable PU pump format with electric dump or dump-and-hold valve behavior for single-acting circuits. Its motor package is configured for 115V, single phase, 50/60 Hz, which is often the deciding factor between closely related model numbers. With a 1.0 gal reservoir, this version occupies a specific capacity point within the series; reservoir sizing should follow the oil demand of the full circuit.
For cycle planning, the key output figure is 20 in³/min @ 10,000 psi; the motor size is 0.5 hp.
Confirm that the connected equipment uses the single-acting circuit this model is configured to control.
