Next Generation Air Powered Hydraulic PumpsIntroducing the ZA4-series, Enerpac’s newest high-pressure hydraulic air-driven pump designed for in-plant, industrial applications and medium to large construction projects. The new ZA4 pump features the Z-Class high efficiency pump design - a design known for its higher oil flow and bypass pressure. Whether powering a cylinder or operating a tool, the ZA’s industry-leading hydraulic flow at 700 bar (10000 psi) will improve productivity in any application. In addition, because of their ATEX 95 certification, the Enerpac ZA Pumps are safe for use in environments such as refinery, petro-chemical and oil gas processing.Reservoirs come in 4 to 40 litres (1 to 10 gal.) capacities. A sight gauge on the 4 and 8 litres (1 and 2 gal.) models and a level gauge on the larger reservoirs allow quick and easy oil level monitoring. The manual control valves on ZA4-series pumps come with built-in user adjustable pressure relief valve. Standard models are available to fit most applications and custom configurations, when required, are available from an extensive ordering matrix. The optional heat exchanger warms exhaust air to prevent freezing and cools the hydraulic oil. Enerpac is a global market leader in high pressure hydraulics. Manufacturer of hydraulic cylinders, pumps, valves, presses, tools, bolting tools, accessories and system components for the manufacturing and construction industries, for productions, maintenance, operation and repair.
