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
