The ZA4-Series pump is best suited to power medium to large size torque wrenches. The ZA4 was developed for the high demands of the oil and gas, chemical processing, rental and other industrial markets.

The stainless steel roll cage resists corrosion and surface damage reducing the maintenance required to prepare the pump for the next job.

The certified lifting eye enables the pump to be transported between levels with a lifting hook avoiding time consuming strapping.
Features
  • The ZA4-Series pump is best suited to power medium to large size torque wrenches. Patent-pending Z-Class technology provides high by-pass pressures for increased productivity. Its high power-to-weight ratio and compact design make it ideal for applications which require easy transport of the pump.
  • Two-speed operation and high by-pass pressure reduces cycle time for improved productivity
  • Glycerin filled pressure gauge with transparent overlays in Ft.lbs and Nm for Enerpac torque wrenches provide a quick torque reference
  • Regulator-Filter-Lubricator with removable bowls and auto drain is standard
  • Ergonomic pendant allows remote operation up to 20 feet
  • Valve technology reduces oil operating temperatures and withstands contaminants to increase pump reliability
  • The ZA-series pumps are tested and certified according to the Equipment Directive 94 / 9 / EC "ATEX Directive". The explosion protection is for equipment group II, equipment category 2 (hazardous area zone 1), in gas and/or dust atmospheres. The ZA-series pumps are marked with: Ex II 2 GD ck T4.
