ZA4-Series, Modular Air Hydraulic Pumps

ZA4 Series, Modular Air Hydraulic Pumps
  • Enerpac ZA4 high pressure modular air hydraulic pumps feature Z-Class high efficiency air pump design; higher oil flow and bypass pressure
  • ATEX 95 certified for use in potentially explosive atmospheres
  • Two-speed pump operation reduces cycle time for improved productivity
  • User adjustable relief valve built-in on manual valves. Oil ports on valves are 3/8″ NPTF
  • Optional heat exchanger warms exhaust air to prevent freezing and cools the oil
  • Full sight oil level glass on 10, 20 and 40 litres reservoirs for easy monitoring of the hydraulic power unit’s oil level, oil level indicators on 4 and 8 litres reservoirs.
