PUJ1200B is a model-specific Enerpac Economy Electric Hydraulic Pump choice for single-acting advance / retract operation. The valve behavior is intentionally simple: advance the single-acting tool, then release pressure for return. Applications that need a hydraulic hold step should use a hold-capable configuration instead.
What the PUJ1200B Model Number Means in Practice
The PU economy design pairs a universal motor with a compact pump package; Enerpac notes that the motor works well with long extension cords or generator-driven power. The pendant moves pump control away from the power unit, which is useful when the operator needs to watch the tool or cylinder. Hydraulic direction comes from a 3-way, 2-position manual valve, matched to single-acting service and advance / retract operation.
Check the hydraulic system's total oil demand against the 0.5 gal reservoir before final selection.
Compare this model with PUJ1200E if the choices look similar. input voltage is 115V on PUJ1200B versus 230V on PUJ1200E. That distinction is more important than the shared series name when matching the pump to the system.
Its motor package is configured for 115V, single phase, 50/60 Hz, which is often the deciding factor between closely related model numbers.
