Industry Focus
Desalination
Corrosion-resistant components for high-pressure pump and membrane systems
Overview
Desalination plants — whether reverse osmosis, multi-effect distillation, or multi-stage flash — operate in some of the most corrosive environments in industry. High-pressure seawater, chlorinated chemicals, and humid salt-laden atmospheres attack standard bearings, seals, and drives rapidly. High-pressure RO feed pumps, energy recovery systems, and brine discharge pumps are critical to plant output — and their component specifications must account for the aggressive operating environment. Drishti Powertech supplies corrosion-resistant SKF bearings, Atlas Copco compressed air systems, and KITO lifting equipment to desalination facilities.
Equipment Challenges
What this industry demands from components
High-Salinity Corrosion
Seawater and brine are highly corrosive to standard carbon steel components. Bearings, housings, and drives must be specified in stainless, coated, or corrosion-resistant materials.
High-Pressure Pump Bearing Loads
RO feed pumps operate at pressures of 60–80 bar. Pump shaft bearings carry high combined radial and axial loads in corrosive seawater environments — requiring precise selection.
Chlorination and Chemical Exposure
Dosing of chlorine, antiscalant, and other chemicals creates chemically aggressive conditions that degrade standard seal compounds and coating systems.
Continuous Operation Requirements
Desalination plants supply potable water — interruptions have immediate public health consequences. Equipment availability and spares supply are critical operational requirements.

Why Genuine Matters in Desalination
Desalination plants cannot afford to discover that a bearing or seal was not rated for seawater service after installation. Material specifications for corrosion-resistant components are not visible externally — only manufacturer documentation confirms that the correct steel grade, coating, and seal compound were used. Drishti Powertech provides genuine SKF components with full specification documentation for seawater service.
