Allweiler has announced the Emtec-C next generation three-screw pump, which removes abrasive machine chips, particles and heat away from cutting surfaces in high-pressure machine tool coolant service. Delivering improved durability it is ideal for metalworking applications, transfer lines and grinding and deep drilling machines.
Emtec-C delivers coolant at a higher rate than centrifugal pumps, allowing machines to run at peak levels without compromising tool life. Innovative features include a new screw system with a patented reversed hanging idler and integrated thrust compensation system for durability, reliability and precision; improvements to seal life expectancy and maintenance requirements; and a unique transparent backflow pipe that alerts the user to possible medium return into the system. The Emtec-C also features an extra-long piston to minimise flow loss. Users have the option of connecting a pressure sensor to the frequency controller for easy control and measurement.
“We’ve improved Emtec-C to achieve maximum three-screw pump efficiency with a lighter weight and fewer components,” said Marko Mandac, Circor Product Manager, three-screw pumps. “Emtec-C is interchangeable with previous models and available in different sizes and spindle pitch angles to accommodate tank-top, submerged and horizontal installation configurations.”
