U Series
ULD / UPD 

Low noise, stainless steel regenerative turbine pump. High self priming capability (UPD)    

Applications 
   General industrial applications
   Integrated with a variety of OEM machines
   Pure water and chemical liquid supply
   Washing solvent supply, suitable for filtration applications
 
 Features
   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
   Self-priming over 8 meters (25 feet)
   SiC x special carbon mechanical seal (model ULD-J) option
   available for pure water (low-viscosity liquid) applications
