External Gear Pumps

The GPA1, GPA2 and GPA3 are fixed displacement external gear pumps, in aluminium, with axial clearance compensation. They allow to obtain high volumetric efficiency even with high operating pressures, a low noise 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 groups from 7.5 of up to 31.7, 27.9 and 61 cm³/rev respectively, with operating pressures of up to 260 bar. Single, tandem, or multiple pumps are available. They are available with four holes European flange and tapered shaft end 1:8, with clockwise or anticlockwise rotation.
