The 1P are fixed displacement external gear pumps with axial clearance compensation. Allow to obtain high volumetric efficiency even with high operating pressures, a low sound impact level. They have a high endurance thanks to the balancing system of the loads on the guide bushings. They are available with displacements ranging from 1,1 to 8,0 cm3/rev and with operating pressures of, up to 230 bar, clockwise rotation direction and with tapered keyed shaft end. The hydraulic connection is with BSP threaded.
