I. Overview of FJX Forced Circulation Pump


The FJX Evaporation Crystallization Circulation Pump operates by utilizing the horizontal thrust generated by the impeller's rotation along the pump shaft, hence also known as a horizontal axial flow pump. It is primarily used in industries such as diaphragm method caustic soda, phosphoric acid, vacuum salt production, lactic acid, calcium lactate, aluminum oxide, titanium dioxide, calcium chloride, ammonium chloride, sugar production, molten salt, papermaking, and wastewater for evaporation, concentration, and cooling purposes. It is used to force circulation to enhance equipment production capacity and increase the heat transfer coefficient of heat exchangers. Therefore, it can also be referred to as an axial flow evaporation crystallization circulation pump.


Section II: Working Principle of FJX Axial Flow Pump


The FJX horizontal axially flow pump transfers liquids not through centrifugal force exerted by the impeller, but by the thrust generated by the rotating blades of the impeller, propelling the liquid along the pump shaft. Once the pump shaft is rotated by the motor, due to the spiral angle between the blades and the pump shaft axis, a thrust (or lift) is exerted on the liquid, pushing it out and along the discharge pipe. After the liquid is expelled, a partial vacuum is formed in the original position. Under the influence of atmospheric pressure, external liquid is drawn into the impeller through the inlet pipe. As long as the impeller continues to rotate, the pump can continuously intake and discharge liquids.


Section 3: Description of FJX Forced Circulation Pump Application


This series of axial flow pumps is widely used in evaporation, crystallization, and chemical reactions in processes across industries such as chemical engineering, non-ferrous metals, salt production, and light industry. Typical applications include:

Phosphate Fertilizer Plant: Forced circulation of the medium in wet-process phosphoric acid concentrator and ammonium phosphate slurry concentrator.

Bayer process alumina plant: sodium aluminate liquid evaporator medium forced circulation.

Membrane-type caustic soda plant: Forced circulation of the medium in the caustic soda evaporator containing NaCl.

Vacuum Salt Production: Forced circulation pump for the medium of the NaCl evaporation crystallizer.

Sodium sulfate factory: Forced circulation pump for Na2SO4 evaporator medium.

Wet metallurgical plant: forced circulation of evaporative crystallizers for copper sulfate, nickel sulfate, etc.

Alkali Plant: Cold crystallizer for ammonium chloride process, forced circulation of brine crystallizer mother liquor ammonia.

Soda Ash Plant: Ammonium evaporation waste liquid recovery process, forced circulation of CaCl2 in the evaporator medium.

Pulp Mill: Forced circulation of the black night medium.

Power Plant: Forced circulation of medium in sulfuric acid ammonium sulfate evaporator crystallizer for flue gas desulfurization, coking plant, and chemical fiber plant.

Light Industry: Forced circulation of process mediums in alcohol concentration, citric acid evaporation, and sugar evaporation positions.
