<p>The invention relates to a volumetric pump used for pumping fluids with a wide range of viscosity, covering medium and high flow rate capacities. According to the invention, the pump comprises a housing (1) outflanked by some external covers (2 and 3), doubled by some inner walls (4), the wall (4) together with the outer cover (3) forming a compartment (c) comprising a pair of synchronizing wheels (5) interlocked by some axes (9 and 10) and some positioning wedges (12), with a pair of rotors (7 and 8) with complementary conjugated or symmetrical profile, any of these pairs being mounted in the housing (1) depending on the pumped fluid.</p> |
