Gy Series High Temperature Molten Salt Circulating Pump

A heavy-duty centrifugal circulation pump engineered to handle high-temperature molten salts (nitrate-based) and other high-temperature heat transfer liquids up to 540 °C. The GY series combines thermal management, robust construction and optimized hydraulics to deliver stable flow with low vibration and long service life in demanding chemical and industrial processes.

Key features

• Designed for continuous circulation and transfer of molten salts at temperatures from 180 °C up to 540 °C.
• Flow capacity: 3 to 600 m3/h; Differential head: 10 to 70 m.
• Handles fluids with dielectric viscosity up to 300 cP.
• Built with effective cooling arrangements and heat-resistant materials to protect bearings and seals at elevated temperatures.
• Benefits include high hydraulic efficiency, smooth operation, low noise, long operational life and reduced maintenance requirements.

Typical applications

• Molten salt circulation and transfer in melamine, alumina and caustic soda production processes.
• Heat transfer and thermal storage loops using nitrate salts in chemical plants and thermal systems.

Commercial and specifying notes for procurement

• Multiple sizes and configurations are available to match system flow and head requirements; provide fluid type, operating temperature, required flow and head when requesting a quotation.
• Ensure system-level provisions for pipe tracing, thermal insulation, appropriate sealing solutions and a compatible cooling circuit for pump bearings/shaft seals as part of installation planning.
• For selection assistance, specify fluid chemistry (salt composition), operating viscosity and any special materials requirements so the pump can be configured for compatibility and longevity.

Quality statement

• The GY series is engineered to meet performance levels comparable with international equivalents for high-temperature molten-salt handling.
