This hydraulic gear pump is design for dump truck.The working rotation direction is double rotation and single rotation, divided into two types: needle roller bearing and oil-free bearing. Needle roller bearing products have stronger anti-pollution ability. The surface of the side plate is plated with a special copper alloy layer, which has enhanced wear resistance. All pumps are tested for pressure and efficiency to ensure normal use after customer installation.
