APPLICATION
Seawater desalination — RO high-pressure feed
High-pressure feed to reverse-osmosis membranes — head far beyond single-stage centrifugal, chloride pitting decides the alloy.
The typical duty
| Fluid | Seawater / Brine |
|---|---|
| Temperature | 35 °C |
| Flow | 200 m³/h |
| Head | 600 m |
What the selector says at this duty
At this typical duty the tool routes to engineering review: A total head of 600 m is beyond the end-suction configurations we have delivered-supplier evidence for (275 m). This typically calls for multistage or API-class hydraulics — we forward it to the manufacturers who build those.
What to watch
- Heads of 500–800 m are multistage or engineered territory — expect the tool to route this to engineering review
- Duplex and super-duplex are the classic wetted answers
- Energy recovery devices share the flow path — ask for them in the same RFQ
