ZA4-Series, Air Hydraulic Pumps
◾Enerpac ZA4 high pressure hydraulic air pumps feature the Z-Class high efficiency air pump design; higher oil flow and bypass pressure
◾Two-speed pump operation and high by-pass pressure reduces cycle time for improved productivity
◾Internal relief valves. One is factory set for overload protection while the second is user adjustable for pre-setting maximum system pressure
◾Sight gauge on 1 and 2 gallon and level gauge on 2.5, 5 and 10 gallon reservoirs allow quick and easy monitoring of the hydraulic power unit's oil level
◾Optional heat exchanger warms exhaust air to prevent freezing and cools the oil
