Vacuum Screw pumps RVS + SCREW

Vacuum screw pump operation.

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 variable pitch hybrid screw, in comparison with traditional screws, considerably increases the efficiency of compression to give faster and more consistent pumping. It also reduces the increase in temperature caused by compression, which means a safer pump. This is particularly important in the discharge of gases, achieved thanks to the special design of the hydrodynamic spiral in the unit’s cooling jacket, which complies with ATEX regulations.

This high performance is also reflected in pump’s energy consumption.
