Sulzer Pumps chose the recent European Desalination Society conference in Barcelona to launch a new high-pressure pump aimed at large seawater reverse-osmosis (SWRO) desalination plants.
The MSD-RO pump, derived from Sulzer’s MSD range is an axially split, multistage, double-volute pump for membrane feed in SWRO plants. Train capacities range from 20,000‑30,000 m³/d.
MSD-RO is the result of Sulzer’s experience in supplying high-pressure pumps for large SWRO plants worldwide totalling 2.5 millions m³/d installed capacity.
The pump delivers a high level of hydraulic performance over its defined operating range, including exceptionally high efficiencies and optimum suction performance. Its top efficiency and robustness complies with the most stringent requirements of the desalination market.
The MSD follows the release in December 2011 of the MBN-RO, Sulzer’s latest ring- section multistage high-pressure pump for membrane feed in RO desalination plants. It has also been designed specifically for high-pressure membrane feed services in SWRO applications.
In addition to its very good efficiency, it allows simple maintenance with quick and easy access to main wear parts, such as mechanical seals or bearings, without disassembling the suction and discharge nozzle.
Manufactured in Duplex or Superduplex as standard materials for a variety of seawater qualities to avoid pitting and crevice corrosion, it covers capacities up to 24,000 m³/d.
