What is an air operated pump?

Posted by IER Services on Apr 15, 2019 11:27:30 AM


An air-operated pump is a positive-displacement reciprocating pump, also called a membrane pump, that is used for the general transfer of liquids. This type of pump is driven by a compressed gas from an outside source.

The compressed gas that is most often used is  just regular air and the directional flow of the internal process liquid is produced from suction and discharge check valves.

Air-operated pumps include four types of pumps that transfer liquids and make use of compressed air as a power source:

  • Air-operated diaphragm pumps
  • Bellows pumps
  • Piston pumps
  • Plunger pumps

These types of pumps are used in facilities of all sizes in a wide variety of industries such as:

  • Food & Beverage
  • Printing & Ink
  • Mining
  • Water Treatment
  • Metal Fabrication
  • Construction
  • Pulp Mill
  • Waste Removal 

Typical valve options include flap valves, butterfly valves, check valves or other kinds of shut-off valves.  Diaphragm pumps are extremely efficient and versatile while also being relatively inexpensive due to the simple operation and design of the pump.

There are many things you need to consider when selecting a pump. Be sure your choice is one that will meet the needs of your specific system or application.
