Product Overview

These 2 stage pumps are based on our Z-Class hydraulic pump platform - widely recognized as the market leader in industrial hydraulic pump technology. ZA Series air driven pumps are built to power medium to large-sized double-acting cylinders and other hydraulic tools.

Choose a ZA Series air over hydraulic pump for high power intermittent use at locations where electricity is not allowed or readily available.

A selection of valve and control options allow you to configure a pump for a wide range of demanding applications. Various reservoir capacities are available, ranging from 1.2 to 10.3 gallons. All include either a sight gauge or level gauge for easy oil level monitoring.

Features
  • Features Z-Class high efficiency pump design, higher oil for high flow and bypass pressure.
  • Two-speed operation and high by-pass pressure reduces cycle time for improved productivity.
  • Intermittent duty power allows users to run the motor between 20-60 minutes at a time, depending on reservoir capacity and sound levels.
  • 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 1.2 and 1.8-gallon and level gauge on 2.6, 5.2 and 10.3-gallon reservoirs allow quick and easy oil level monitoring.
  • Optional heat exchanger warms exhaust air to prevent freezing and cools the oil.
  • ATEX Certified
