This equipment utilizes compressed air to displace liquids from one location to another. An example includes drawing chemicals from a storage tank into a mixing vessel, or evacuating water from a flooded area. The operational principle relies on a pressure differential created by the introduction and venting of compressed air within the pump chamber, effectively pushing the fluid through an outlet.
Such devices are favored due to their portability, self-priming capabilities, and ability to handle a wide range of fluid viscosities and solids content. Their adoption is rooted in the need for efficient and safe fluid movement across various industrial and commercial sectors. Historically, their development stemmed from simpler pneumatic systems, evolving into more sophisticated and reliable designs for demanding applications.
