Sulzer Launches Next Pump Generation For Desalination

Global pump specialist Sulzer has expanded its portfolio of high-performance products for the desalination sector. The MSN-RO high pressure pump range combines proven features from existing Sulzer designs with multiple enhancements to optimize both capital and operating costs. In addition, the AHLSTAR range of charge pumps has been extended with increased capacities suitable for modern large-scale desalination projects.

The MSN-RO high-efficiency pump is designed for modern, large-scale desalination applications with large, independent RO trains with capacities up to 35’000 m3/d. The multistage axial split casing pump is based on existing Sulzer designs that have a proven track record in the sector. Its hydraulic section, lubrication system and balancing devices come from the MBN-RO pump. Its axial split casing, designed to simplify maintenance, is derived from the MSD-RO range.

The MSN-RO also incorporates several significant enhancements, designed to improve operating efficiency while reducing capital costs. The diffuser and discharge volute have new high-efficiency designs, optimized through extensive computational fluid dynamics (CFD) analysis. The renewable stationary wear parts within the pump are manufactured from polyetheretherketone (PEEK) engineering polymer, with minimal clearances for the highest efficiency.
