New from Enerpac is the ZA4-series of high-pressure hydraulic air-driven pumps for powering tools and hydraulic cylinders on medium to large construction projects. It has the Z-Class high efficiency pump design with 700 bar operating pressure.

ATEX 95 certification means the pumps can be used in refinery, petrochemical and oil & gas processing applications. A range of reservoir capacities is available between 4 and 40 litres.

Oil level can be monitored by a sight gauge on the 4 and 8 litre models and by a level gauge on the larger reservoirs. User adjustable pressure relief valves are built-in to the manual control valves and an option is a heat exchanger to prevent freezing and to cool the hydraulic oil.
