Internal gear pumps The IGPs are volumetric pumps with fixed displacement with internal gears, available in five quantities divided in turn in different displacements. They are characterized by a high volumetric performance, thanks to both radial and axial compensation proportional to the operating pressure, and from a low noise level. The optimal distribution of loads and the particular bronze bearings allow you to operate at high pressures in continuous exercise and give the pump a long duration. IGP pumps are also available in multiple versions combined in multifuxe groups.
