ST / STS / STW / STWS

High pressure cast iron regenerative turbine pump  

Applications 
  General industrial applications
  Pure water and chemical liquid supply
  Washing solvent supply, suitable for filtration applications

Features
  No metal contact between the impeller and the casing and cover, eliminating wear and reducing contamination
  Simple robust structure with minimal consumable parts, suitable for processes requiring high reliability
  Due to selection of material combinations (SUS304 / PTFE / SiC) can target variety of applications
  Very low noise levels silimar to centrifugal pumps, additional noise reduction measures not required
