The R4.5/45 FL-Z-UNI-SD165-SO gear pump is composed of components such as two precisely machined gears, a pump body, front and rear covers, and a safety valve.
Its working principle is simple yet highly efficient: When the gears rotate, the volume of the space on the side where the gears disengage gradually increases, creating a vacuum that draws the liquid into the pump. Meanwhile, the volume of the space on the side where the gears mesh gradually decreases, squeezing and pushing the liquid into the discharge pipeline. This mode of operation ensures continuous and quantitative delivery by the pump, with the flow rate directly related to the pump's rotational speed.
