Problem
The site needed more stable RO feed pressure and reduced downtime caused by pressure loss, cavitation symptoms, or duty mismatch.
Engineering Considerations
FlowCore would review membrane pressure, feed water quality, TDS, suction tank level, NPSH, stainless material, VFD potential, and CIP exposure.
- Membrane feed pressure
- NPSH margin
- SS304 or SS316 suitability
- VFD control
- Operating hours
Solution Approach
A high-pressure vertical multistage pump selection is typically reviewed for RO feed duty where compact footprint and stable head are required.
Result and Lessons
RO pump upgrades should be based on the membrane system requirement, not a motor-size replacement. Pressure stability protects both output quality and membrane life.
