Flowserve DS-RO Industrial Process Pump

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.

Applications

  • Water Management
  • Desalination

Key Features

  • Temperatures to 45°C (113°F)
  • Frequency of 50 or 60 Hz; compatible with VFD applications
  • Sizes from 200 to 700 mm (8 to 28 in)
  • 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.
