gear pump sizing calculator a gear pump is a rotary pump that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gear to transport or pressurize liquid. it consists of two gears, pump body and front and rear covers to form two enclosed spaces. when the gear rotates, the volume of the space on the disengaged side of the gear changes from small to large, forming a vacuum to suck the liquid, and the volume of the space on the gear meshing side changes from large to large. small, the liquid is squeezed into the pipe. the suction chamber and discharge chamber are separated by the meshing line of two gears. the pressure at the outlet of the gear pump depends entirely on the resistance at the pump outlet.
