Screw Pumps

Our screw pumps are volumetric self-priming pumps suited to handle oils and liquids with a minimum lubricating quality.The design simplicity makes these pumps intrinsically reliable and efficient. Three screws rotate inside a replaceable 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.
