SCREW PUMPS INTRODUCTION POMPE A VITI are volumetric self-priming pumps suited to handle oils and liquids with a minimum lubricating quality. The simplicity of the design makes these pumps intrinsically reliable and efficient. Three screws rotate inside a casing with close tolerances, thus forming sealed chambers and provoking the axial displacement of the fluid. The idler spindles rotate without contact with the driving spindle because of the fluid itself, thus being free from radial forces. The accurate hydraulic balance and the special profile of the screw thread guarantee a continuous flow...

SCREW PUMPS INTRODUCTION POMPE A VITI Built in pressure relief valve, on demand Close manufacturing tolerances guarantee high volumetric efficiency and low noise. Groove ball bearing, lubricated by the fluid to be pumped (internal pump design). Epicycloidal profile hydraulically balanced driving spindle. A rational and unique technical solution. Thermal compensation and hydraulic sealing insert. Coupling flange (ISO flange in the standard version). Maintenance-free unbalanced mechanical seal, constantly maintained at inlet pressure. Hypocycloidal profile idler spindles hydraulically driven by the...
