Background

Gear pumps are rotary pumps that deliver or pressurize fluid by virtue of the change in working volume and movement created between a pump cylinder and a meshing gear. Two gears, pump body and front and back covers form two closed spaces, when the gears rotate, the space on the gear disengagement side becomes larger from smaller to larger to form vacuum to suck liquid, and the space on the gear engagement side becomes smaller from larger to smaller to squeeze liquid into the pipeline. The suction chamber and the discharge chamber are separated by a meshing line of two gears. The pressure at the discharge of the gear pump is entirely dependent on the amount of resistance at the pump outlet.
