Manufacturer of flow and motion control products, CIRCOR, has announced the launch of the EMTEC-C, the next generation of the Allweiler three-screw pump which moves abrasive machine chips, particles and heat away from cutting surfaces in high-pressure machine tool coolant service.
Designed for use in metalworking applications, transfer lines, and grinding and deep drilling machines, the EMTEC-C delivers coolant at a higher rate than centrifugal pumps, allowing machines to run at peak levels without compromising tool life.
The EMTEC-C is now lighter and with fewer components. It has a new screw system with a patented reversed hanging idler and integrated thrust compensation system for durability and precision. There have also been improvements to seal life expectancy and the need for maintenance, while a transparent backflow pipe alerts the user to possible medium return into the system. There is also an extra-long piston which minimises flow loss and the option to connect a pressure sensor to the frequency controller for easy control and measurement.
In addition, the surface of EMTEC-C has a hardness similar to ceramic in the housing bores yet is elastic enough to eliminate the danger of bore surface fracture.
