EMTEC pumps are specifically designed to withstand the harsh environment of a high-pressure machine tool coolant service. Special hardening techniques produce a surface hardness similar to ceramic in the housing bores while maintaining elasticity that eliminates the danger of bore surface fracture. The rotors are hardened to reach long lifetimes. The power rotor’s balance piston is extra-long, which improves the pump’s volumetric efficiency. Flow that crosses the balance piston serves to cool and lubricate the silicon carbide mechanical shaft seal faces. For more information, visit www.circorpt.com/emtec.
