The working principle of gear pumps

Working principle of gear pumps: The driving gear with internal teeth (outer rotor) rotates in the same direction as the inner rotor within a fully enclosed pump housing. The crescent-shaped plates on the pump housing and front cover separate the suction port from the discharge port. As the gears rotate, a negative pressure is created at the suction port, drawing liquid into the pump.
