CSX BETWEEN BEARING PUMP

Brand IDP
Description The Flowserve CSX Between Bearings Pump is a Horizontal Multistage Pump designed for high-efficiency, high-pressure membrane feed applications, especially in reverse osmosis desalination systems. With advanced corrosion-resistant materials and precision design, it delivers reliable, energy-efficient performance and reduced lifecycle costs.

  • High-Efficiency Performance: Advanced hydraulic design with precision-cast impellers and optimized diffusers to minimize energy losses.
  • Corrosion-Resistant Construction: Super Duplex Stainless Steel (A890 Gr. 5A/6A) for harsh environments.
  • Precision-Cast Impellers: Dynamically balanced to G2.5 standard for smooth, stable operation.
  • Lubrication Flexibility: Product-lubricated or oil-lubricated bearing options.
  • Stiff Rotor Design: Reduces deflection, extending bearing and seal life.
  • Flexible Nozzle Configuration: Nozzle heads configurable in 90° increments.
