The Screw-Centrifugal Pump from Hidrostal Pumps has durable construction suitable for the handling of solids in suspension and viscous liquids, as well as for applications with larger negative suction heads. They are available in a bearing frame configuration. This type of installation in a dry area permits direct access for maintenance and monitoring. This execution offers flexibility in the choice of drive and makes possible the installation of larger motors. For operation in areas that are wet or are susceptible to flooding, an immersible model can be used. A self-cooling system that is independent of the medium being handled ensures universal use. Various monitoring elements can be built into all motor sizes. www.hidrostalpumps.com.
