CR Vertical Multistage Centrifugal Inline Pumps

  • CR Vertical Multistage Centrifugal Inline Pumps SKU104

    The CR vertical multistage centrifugal inline pumps are designed for water supply, water treatment and almost any industrial solution including high-pressure, hot, dangerous, flammable and aggressive liquids. Recently, the range has been upgraded with a new, more robust generation of CR pumps (CR 95, CR 125 and CR 155), offering an optimised hydraulic design for world-class energy efficiency.

    CR pumps have been developed using simulation-driven design to perfect every single component and have been field-tested around the world, so you can install and operate the range with total confidence. The CR is available in millions of different configurations through four modules including Motors, Shaft seals, Pump modules and Connections. The CR pump range is available in four different materials: cast iron, two grades of stainless steel and titanium. Thirteen flow sizes are capable of producing up to 180 m3/h at 50 bar, with a variety of shaft seals, rubber materials and supply voltages.
