NETZSCH introduces NOTOS multiple screw pumps

imageedit 2 7200596954NETZSCH Pumpen & Systeme GmbH has launched its NOTOS line of multiple screw pumps for pumping applications in the oil and gas, marine, power and general industrial markets

The company’s multiple screw pumps have been designed aiming to handle difficult media including low to high lubricant fluids, low to high viscosity, shear sensitive or chemically aggressive media.

According to NETZSCH, NOTOS multiple screw pumps are hydraulically balanced and aim to deliver efficient pumping with low axial force. The low-maintenance pumps also focus on providing quiet operation and continuous flow without pulsation or turbulence in a long service life. These pumps also provide high suction power of up to eight masl in a small footprint.

“The two-screw pump operates with a drive screw transferring torque through a hydraulic film to the intermeshing driven screw, while the three-screw pump operates with a drive screw transferring torque through a hydraulic film to the two intermeshing driven screws. 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,” said the company.

NETZSCH further added, “In the four-screw pump, two shafts with four screws rotate inside a cartridge, without any metal-to-metal contact. The torque is transferred to the driven shaft via helical or spur timing gears, with reduced vibration and noise.”
