Flowserve DVSH-RO is a single-stage, high-pressure membrane feed pump designed for heavy-duty seawater reverse osmosis service. Built on the ISO 13709/API 610 (BB1) DVSH platform, its optimized hydraulics, side-by-side nozzles and corrosion-resistant materials support efficient, stable and reliable desalination operation across a wide flow range.
Key Features
- Double-suction impeller balances axial thrust and minimizes NPSHr to support efficient, stable membrane feed operation
- Double-volute, axially split optimized-weight casing reduces radial forces and shaft deflection to extend bearing, seal and wear-ring life
- Heavy-duty shaft runs with a short bearing span that helps limit deflection
- Lower-half nozzles enable disassembly without disturbing piping and accommodate loads meeting or exceeding ISO 13709/API 610 requirements
- Synthetic wear rings provide high efficiency operation
