(SZ) Bombas de inmersión de succión rápida | Quick suctioning immersion pumps

Las bombas de inmersión de aspiración rápida del tipo SZ son ideales para bombear medios con una alta carga de aire, como emulsiones, aceites de molienda y de corte. El rodete de la SZ es una combinación de rodete abierto y rodete de compresor, que permite el transporte simultáneo de aire y medios con carga de sólidos. Esto hace que la bomba SZ sea la bomba de inmersión de aspiración rápida ideal para casi todos los procesos en la tecnología de molienda y el mecanizado pesado. Gracias al diseño del rodete abierto, se pueden bombear fácilmente partículas extrañas de hasta 20 mm de diámetro. Ofrecemos esta serie de bombas para caudales de 50 a 1.800 l/min y para alturas de transporte de hasta 50 m. Un casquillo de estrangulamiento de carburo de silicio sin mantenimiento proporciona la estanqueidad y la guía necesarias del eje.

The quick suctioning immersion pumps type SZ are ideal for pumping media with high air inclusion such as emulsions, grinding and cutting oils. The impeller of the SZ is a combination of an open impeller and a compressor impeller, which allows the simultaneous transport of air and media with solids loading. This makes the SZ pump the ideal quick suctioning immersion pump for almost all processes in grinding technology and heavy machining. Due to the open impeller design, foreign particles up to a diameter of 20 mm can be pumped easily. We offer these pump series for flow rates of 50 to 1,800 l/min and for delivery heads up to 50 m. A maintenance-free silicon carbide throttling bush sealing provides the necessary shaft sealing and guiding.
