A12VV 4/16-4/4

     Being essentially one of oil pumps, the 2VV two-screw pump can also transfer non-greasing (both pure and polluted) liquids with the contents of mechanical nonabrasive impurities within 25% by mass and 0,2 mm in size.
     The working parts of the pump - the case (yoke) and the rotors (both driving and driven ones) are located in adjacent through bores of the body. The rotors have double-sided worms of special form.
