INTERNAL GEAR PUMPS OPERATING PRINCIPLE — IGP pumps are volumetric displacement pumps with 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. — 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.

SERIES 10 3 - PERFORMANCES PUMP SIZE (obtained with mineral oil with viscosity in the range of 25 ÷ 100 cSt) NOMINAL DIMENSION DISPLACEMENT MAX. FLOW RATE (at 1500 rpm) [cm3/rev] [l/min.] (note 2) PRESSURE [bar] (note 3) steady/peak MIN. ROTATION SPEED [rpm] (note 4) In continuous operating conditions, the maximum suction pressure is 2 bar while the minimum pressure must not be less than -0,2 bar. A minimum suction pressure of - 0,4 bar is allowed for brief periods of time (the pressure values are to be considered relative). The working tolerances can reduce the displacement by 1,5% max.
