PreroClean

Self-cleaning pump sump

The Hidrostal PreroClean self-cleaning pump sump is a simplified and standardised version of the PREROSTAL system. Through the rotating movement of the media before the pump entrance, all the suspended solids and particles are fed into the pump. This cleaning process takes place once per pump cycle. By this process, the pump sump is kept free of any deposits and soiling.

Prerostal

A highly effective sump cleaning system

The PREROSTAL Prerotation system is a unique, economical, uncomplicated method of automatically adjusting pumping volume to varying inflow rates using a constant speed motor and pump. It combines the screw centrifugal impeller characteristics of a Hidrostal pump with a specially configured vortex inducing chamber around the suction pipe of the pump. PREROSTAL is a highly effective sump cleaning system which does not require any additional items or moving parts. It is the ideal solution for handling variable flow applications with large solids.
