Molten Salt VTP PumpMolten Salt VTP Pump

Brand: Flowserve
Description:

The Molten Salt VTP Pump is a vertical turbine pump specifically engineered for the safe and efficient handling of molten salts at extremely high temperatures, typically ranging between 290°C and 600°C. Designed for applications in concentrated solar power (CSP) plants, thermal energy storage systems, and industrial heat transfer processes, this pump provides reliable performance where standard pumps would fail due to thermal stress.

Featuring high-temperature metallurgy, thermal barriers, and special shaft sealing systems, the Molten Salt VTP Pump ensures minimal thermal deformation, low heat transfer to drive components, and maximum system uptime. Its vertical, multistage construction allows for deep sump installation and consistent flow even in large-scale molten salt circuits.

Ideal for solar farms, chemical plants, and high-temperature storage systems, this pump supports efficient energy transfer, extended service intervals, and minimal maintenance under the most challenging operating conditions.

Built upon the popular VTP pump, Flowserve Molten Salt VTP was designed using advanced thermal mapping software to ensure adequate heat dissipation and mitigate distortion. Available in single or multistage diffuser designs.
