Allweiler Three-screw Pump for Machine Tool Coolant Service
By Mario Cywinski
Allweiler 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. EMTEC-C has improved durability and efficiency, and used for metalworking applications, transfer lines, and grinding and deep drilling machines.
“We’ve improved EMTEC-C to achieve maximum three-screw pump efficiency with a lighter weight and fewer components,” said Marko Mandac, Product Manager, Three-screw Pumps. CIRCOR. “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.”
EMTEC-C delivers coolant at a higher rate than centrifugal pumps, allowing machines to run at peak levels without compromising tool life. 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 transparent backflow pipe that alerts the user to possible medium return into the system.
EMTEC-C features an extra-long piston to minimize flow loss. Users have the option of connecting a pressure sensor to the frequency controller for easy control and measurement.
