road grader External Gear Pumps

Introduction of 1.5BDPF 1.5BDPF**series external gear pumps have a floating busing with automatic axial clearance compensation. A gear pump works on the principle of displacement. As the gears rotate inside the gear pump chamber, they create areas of low and high pressure. An area of low pressure, or vacuum, is created between the teeth of the gears when they un-mesh. Liquid flows into this area of lower pressure. As the gear continues to rotate, the liquid becomes trapped in the pocket formed by the gear teeth and the wall of the pump chamber. Finally, an area of higher pressure is created once the gears begin to mesh, forcing the liquid from the gear teeth and into the discharge outlet. Extremely small clearances between the gear teeth and the wall are required in order for the pump to work effectively. Specifications Dimensions Ordering code
