The pump supplied, is a “ VOLUMETRIC PUMP TYPE”.
The MVG-MVI pumps can manage suspended solids with approximate dimension less than
10-12mm for soft solid and up to 3mm for crushproof solid.
The main part of Gianneschi pump is the single helix metal rotor which rotates eccentrically
within a double helical resilient stator of twice the pitch length of the rotor.
The rotor of circular cross section forms a cavity as it rotates.
The cavity progresses towards the discharge port carrying the pumped liquid inside this
cavity by the continuously formed of seal line.
