Vacuum screw pumps RVS + SCREW by PEDRO GIL

Increased compression efficiency for faster, smoother pumping

Pumps designed with a single screw for a wide range of chemical and industrial processes. Two rotors turn in opposite directions without touching each other or the housing, appropriately geared and housed within the pump unit and without any liquid valve closure. The rotors are synchronized through a pair of gears sucking the gases from the liquid closure process and moving them, by way of other rotors to the discharge flange.

The hybrid screw design with technical combination of variable pitches increases the compression efficiency compared to traditional designs and provides significantly faster and smoother pumping. The resulting reduction in heat generation makes safe pumping possible. The unique hydrodynamic spiral jacket cooling enables ATEX. In addition, cooling is no longer necessary up to 800 m3/h.
