The IGP are volumetric pumps with fixed displacements and internal gears, available in five sizes, each divided into a range of different displacement. The pumps feature high volumetric performance levels, thanks to both radial and axial compensation in proportion to operating pressure, in addition to low noise levels. The optimal load distribution and special friction bearings enable continuous duty at high pressures and ensure extended pump lifetime. IGP pumps are also available in multiple versions which can be combined to make multi-flow groups.
