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 efcient. Three screws rotate inside a casing with close tolerances, thus forming sealed chambers and provoking the axial displacement of the uid. The idler spindles rotate without contact with the driving spindle because of the uid itself, thus being free from radial forces. The accurate hydraulic balance and the special prole of the screw thread guarantee a continuous ow with minimum...

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