Haskel - Series AW Air Driven Liquid Pumps


For Pumping Hydraulic Oil and Corrosive Liquids at High Pressures Using Shop Air Pressure for Power

Air Driven Liquid Pumps offer many advantages:
  • They can stall and hold virtually any pressure with no flow or internal leakage.
  • Operate safely in hazardous atmospheres and wet environments.
  • Pump non-lubricating fluids such as water or solvents to very high pressures.
  • Operate from small tanks in fluid power units for maximum portability.
  • Start under full load.

Constructed of nickel plated steel and stainless steel, with polyurethane and buna-N seals. Operates from air supply of 25 to 150 PSI or from nitrogen, carbon dioxide, or natural gas. The approximate size is 8" square and 12 1/2" high. Weight is 24 lbs. Single head models produce about 1 1/4 HP of pumping power. Use a cut-off valve, a filter and pressure regulator of at least 1/2" NPT size in the inlet air supply. Do not use a lubricator. The pumps are permanently lubricated with Molykote and air line lubrication may wash out the lubricant. Use an air muffler on the air exhaust port. Install a 100-mesh filter in the hydraulic inlet. Pump should be mounted no more than about 2 feet above the surface of the liquid being pumped. Inlet and outlet air ports are 1/2" NPT. Bottom inlet port on AW-B10 and AWB15 is 1" NPT. Side inlet port on all other models is 1/2 NPT. Control maximum outlet hydraulic pressure by adjusting the regulator in the inlet air line.

Haskel - Series M Air Driven Liquid Pumps
Low Cost • Miniaturized • Pressures up to 15,000 PSI

A smaller version of the Series AW, handling the same liquids and delivering 1/3 HP out and working from an air line of 25 to 125 PSI. An economical means of using shop air or vehicle compressor air to produce hydraulic pressures up to 15,000 PSI. They provide an inexpensive way of replacing hand pumps.

Standard Series M pumps are constructed of cad plated steel, aluminum, and stainless steel with polyurethane seals. For pumping hydraulic oil, kerosene diesel fuel or water with 5% soluble oil. Other models are shown below for pumping mildly corrosive liquids.

Inlet and outlet air ports are 1/4" NPT. Inlet oil port is 3/8" NPT and outlet is 1/4" NPT. Approximate size is 6" long × 3 1/4" square. Weight 6 lbs.
