Quick Suctioning Pumps from Schmalenberger for Heavy Metal Machining


The SZ is an immersion pump for practically every heavy metal machining and grinding technology process. Wherever large volumes of coolant are encountered in conjunction with chip material and metal particles, it is an indispensable part in the process chain.

Foreign particles with a diameter up to approx. 20 mm can be delivered without difficulty through the open impeller design.
