ATOS Atos PFG gear pump is a rotary pump that transfers liquid or pressurizes it by relying on the change and movement of working volume formed between pump cylinder and meshing gear. Two enclosed spaces are composed of two gears, pump body and front and rear covers. When the gear rotates, the volume of the space at the gear disengagement side increases from small to large, forming a vacuum, which sucks in the liquid. The volume of the space at the gear engagement side decreases from large to small, squeezing the liquid into the pipeline. The suction chamber and discharge chamber are separated by the meshing line of two gears. The pressure at the outlet of the gear pump completely depends on the resistance at the pump outlet
