V volumetric internal gear pumps are used in applications where the management of clean fluids with high viscosities is required.
They are used in all industrial applications where a delicate treatment of the pumped product is required, preventing chemical-physical alterations.
Volumetric rotary, they ensure flow rates proportional to the rotational speed and con-stant pulse-free flows, regardless of the back pressure.


Up to 240 m3/h


Up to 200 mm

Standard Construction Materials

Cast iron, treated cast iron, carbon steel, stainless steel


20 - 100.000 [mm2/s - cSt]


Up to 16 bar


Up to 200°C

  • Constant flow rate. Proportional to the number of revolutions, regardless of back pressure
  • Continuous flow. Pulse-free and no pressure peaks, hence no system vibrations
  • Versatility. With the same pump, use the rotor axis adjustment device to pump liquids with viscosity below that or water or high viscosity liquids
  • Reversibility. By changing the direction of rotation you change the direction in which the liquid flows, keeping the features and performance unchanged
  • Self-priming. The high degree of vacuum that can be achieved makes fast self-priming possible at the maximum heights allowed by the physical conditions of the pumped liquid
V – Bare shaft
V… BP – Base and joint
