Molten salt applications

A mixture of sodium nitrate (NaNO3) and potassium nitrate (KNO3), molten salt — like that used in concentrated solar power plants — possesses high thermal conductivity, allowing temperatures to reach 600°C (1,100°F). As a leading provider of molten salt pumps for more than 60 years, Flowserve understands the detrimental effects of heat distortion on a vertical pump.

ISO 13709/API 610 compliance

VTP pumps are available in a configuration that meets ISO 13709/API 610 standards. They are engineered for easy maintenance, high efficiency and long life in demanding applications found in the oil and gas and related industries. Key features include weld neck flanges; precision pump-to-motor couplings; a one-piece pump shaft; dynamically balanced, keyed, enclosed impellers; pinned wear rings; and API 610 forces and moments.

Barge stripping applications

Specifically designed for transportation barges, the Flowserve Barge Pump continues to be the premier brand used on inland and coastal waterways. It is a vertical self-contained, self-priming unit designed for barge unloading and transfer operations. With the high-efficiency Barge Pump, stripping turnaround times are kept to a minimum. Furthermore, its innovative pollution-prevention design inhibits costly oil and chemical spills.

Groundwater development

For irrigation and agriculture markets, pre-engineered designs, standardized materials and stocked components provide a reliable vertical turbine pump that minimizes price without sacrificing quality or performance.
