FGL High-Temperature Vertical Axial-Flow Pump for Molten Salt

I. Overview of FGL Axial Flow Pumps

The FGL type high-temperature molten salt axial flow pump is a new generation energy-saving high-temperature molten salt axial flow pump product developed by Flying Pump Industry Co., Ltd. Based on the company's experience in manufacturing vertical chemical axial flow pumps and high-temperature molten salt submersible pumps, and absorbing the advantages of foreign industry technology, in response to market needs. It is mainly used for phthalic anhydride, maleic anhydride, and isophthalic anhydride.Acrylic acidIndustrial processes including fumaric acid, melamine, refrigerants, and aluminum-magnesium industries, as well as rubber and plastic industries that transport high-temperature liquids such as sodium salts, potassium salts, and alkalis, which are prone to crystallization.

The FGL vertical chemical axial flow pump features a single-stage cantilevered structure, with a rational design, excellent cavitation resistance, and high reliability. The pump is designed for a pressure of 10bar and can handle medium temperatures up to ~+120°C. It is suitable for transporting media containing solid particles in large flow rates and low lift evaporation circulation stations, and is a designated optional pump type for the phosphate fertilizer industry.

Section 2: Applications of FGL Vertical Axial Flow Pumps

Phosphate fertilizer industry: Suitable for conveying corrosive media containing solid particles, such as flash steam cooling stations.

Chemical, alkali, salt production industry: Suitable for material concentration and recycling stations.

Papermaking & Light Industry: Suitable for concentrated recycling stations for materials.

Section 3: FGL Vertical Axial Flow Pump Structure Description

Utilizing a guide vane structure, the pump exhibits excellent anti-cavitation performance and high efficiency.

Pump operates at low speed with smooth and reliable performance.

The impeller and impeller housing are matched, allowing for easy replacement of both when transporting erosive materials, thereby extending the service life of the pump body.

Available with direct drive, belt, or reducer transmission options.

IV. Material Selection for Overcurrent Components

Available materials include CD4MCu, Cr30, 304, 304L, 316, 316L, 904L (UB-6), and 20# alloy.

Impeller and impeller body for the flash steam cooling station in the phosphate fertilizer industry are made of Cr30 material, while the pump body is constructed with CD4MCu material.
