The GP 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 also have a high endurance thanks to the balancing system of the loads on the guide bushings. They are divided into three dimensional displacements ranging from 1.3 of up to 9.1 - up to 27.9 and 87.6 cm3/rev respectively, with operating pressures of up to 250 bar and up to 270 bar for the high pressure version. They are available with clockwise, counterclockwise and reversible rotation, with shaft end type tapered, keyed with thread, cylindrical keyed, or splined. They also come as single or coupled pumps.
