The Flowserve DS-RO single-stage, end-suction, foot-mounted pump

Industrial Process Pumps - DS-RO

BRAND: Worthington

The Flowserve DS-RO single-stage, end-suction, foot-mounted pump is engineered specifically for auxiliary applications found in reverse osmosis desalination processes. Developed in accordance with ISO 5199, this versatile pump is well-suited for plant support services such as pretreatment, boosting and product water supply. Optimized hydraulics and desalination-specific materials of construction provide high-efficiency performance and long-term reliability that result in increased uptime with low cost of ownership.

Product Highlights

Industries

  • Water

Industry Sectors

  • Water
  • Desalination

Operating Parameters

  • Flows to 6,000 m³/h (26,000 gpm)
  • Heads to 180 m (530 ft)
  • Pressures to 25 bar (365 psi)
  • Temperatures to 45°C (113°F)
  • Frequency of 50 or 60 Hz; compatible with VFD applications

Design Range

Sizes: DN 200 to 600 (8 to 24 in)

Pressure class: PN 25 (365 psi)

Materials: 

  • 316 stainless steel 
  • Super duplex (A890, Grade 5A; PREN ≥ 40)
  • Optional Alloy 885 (PREN ≤ 40)

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.
