About this product

The Flowserve DS-RO single-stage, end-suction, foot-mounted pump is engineered specifically for auxiliary applications found in reverse osmosis desalination processes. This versatile pump is well-suited for plant support services such as filtered water, low- or high-pressure feed boosting, potable water, backwash and others. Optimized hydraulics and high-alloy materials of construction, like ASTM A890 Grade 5A/6A super duplex stainless steel, provide high-efficiency performance and long-term reliability that result in increased uptime with low cost of ownership.

 

 

Features and Benefits

  • A rigid shaft and double-volute casing keep shaft deflection low, reducing radial load and promoting high sustained efficiency.

  • End-suction design with a choice of three alternative discharge nozzle locations provides system flexibility.

  • Materials of construction are designed to withstand the corrosive environments typical of desalination processes.

  • Double-volute casing provides stable operation. Radial thrust loads are minimized, reducing vibration and mechanical loads on all components.

  • Parts interchangeability over a range of pump sizes lowers spare part inventories and costs.

  • A spacer-type coupling allows full inspection of the back pullout type pump in minimum time, without disturbing suction and discharge connections.

  • The closed impeller utilizes three dimensionally contoured blades extending into the impeller, combining high efficiencies and low NPSHR.
