Specifications
  • Patented Z-Class pump technology provides high by-pass pressures for increased productivity—important in applications using long hose runs and high pressure-drop circuits, like heavy lifting or certain double-acting tools. Enerpac ZU4 Hydraulic Pumps are built to power small to large-sized cylinders or hydraulic tools, or wherever highspeed, intermittent duty, remote hydraulic power is needed.
  • Features Z-Class high-efficiency pump design; higher oil flow and bypass pressure, cooler running and requires 18% less current draw than comparable pumps
  • Powerful 1.7 hp universal electric motor provides high power-to-weight ratio and excellent low-voltage operating characteristics
  • High-strength, molded composite shroud protects motor and electronics, while providing an ergonomic, non-conductive handle for easy transport
  • Low-voltage pendant provides additional safety for the operator (remote control units)
  • Classic Electric Pump:
    • The Classic has traditional electro-mechanical components (transformers, relays and switches) in place of solid-state electronics. The Classic delivers durable, safe and efficient hydraulic power.
  • Pro Electric:
    • LCD readout provides pressure and a number of diagnostic and readout capabilities never before offered on a portable electric pump
      • pump usage information, hour and cycle counts
      • self-test, diagnostic and read-out capabilities
      • pressure readout and auto-mode pressure settings
