U Series
ULD / 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
