Multiple screw pumps
Multiple screw pumps
NETZSCH Pumps North America’s new NOTOS™ line of multiple screw pumps is designed for demanding pumping. The pumps are hydraulically balanced, delivering efficient pumping with very low axial force. The two-screw pump operates with a drive screw intermeshing with a driven screw transferring torque from one to the other, while the three-screw pump operates with a drive screw intermeshing with two driven screws that transfer torque from one to the other. In both, the screws are surrounded by a ferrous pump housing, and together, the screw geometry and housing form the pumping chamber. Rotation, screw diameter, and screw pitch define the pump’s flow rate.
