NETZSCH Releases Innovative NOTOS(TM) Multiple Screw Pumps
Multiple Screw Pumps deliver high volumetric efficiency and easy maintenance across diverse media and markets
NETZSCH Pumps North America, LLC, experts in solutions designed specifically for difficult pumping applications, announces the release of its new NOTOS™ line of multiple screw pumps for demanding pumping applications in the Oil & Gas, Marine, Power, and General Industrial markets. NETZSCH’s Multiple Screw Pumps are designed to handle difficult media, including low to high lubricant fluids, and low to high viscosity, shear sensitive, or chemically aggressive media.
NOTOS Multiple Screw Pumps are hydraulically balanced, delivering efficient pumping with very low axial force. The low-maintenance pumps offer quiet operation and continuous flow without pulsation or turbulence over a long service life. These pumps offer high suction power of up to 8 m.a.s.l. in a small footprint.
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 two- and three-screw pumps, 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.
In the four-screw pump, two shafts with four screws rotate inside a cartridge. The screws do not touch each other, and do not touch the cartridge; therefore, there is no metal-to-metal contact in this pump type. Synchronization of the two shafts is effected by a pair of timing gears remote from the pump chamber.
