Main Applications

• Pump for water desalination systems (reverse osmosis applications)

Benefits

• Double volute from DN 80 (3 in.): low radial thrust and also reduced shaft deflection extend the service life of bearings and also mechanical seal.
• Easy to service thanks to back pull-out design
• Dimensioned for longer service life than specified by API 610, reducing maintenance expenditure and also work
• Also Tandem bearing arrangement absorbs high axial forces
• Cast steel bearing brackets with integrated cooling fins enable higher fluid temperatures and also reduce bearing temperatures.
• Optional fan impeller: also no cooling water supply required for high temperatures
• Also Wetted components made of super duplex stainless steel for optimum corrosion resistance
• Also Optimised KSB mechanical seal for maximum operating reliability
