HSDFC forced circulation pump can be widely applied to evaporation, crystallization, chemical reaction and other processes in chemical industry like non-ferrous metallurgy, salt making, light industry and so on. Its typical application scope is as follows:
- Phosphate fertilizer plant: concentration of wet process phosphoric acid, Forced circulation of phosphoric acid slurry in evaporator system;
- Bayer process alumina plant: the forced circulation of sodium aluminate lye in evaporator system;
- Diaphragm caustic soda plant: forced circulation of caustic soda in evaporator;
- Vacuum salt making: the forced circulation of sodium chloride in evaporation crystallizer;
- Mirabilite factory: the forced circulation of the Sodium sulphate in evaporator;
- Hydrometallurgy plant: forced circulation of Copper sulfate and nickel sulfate medium in evaporation concentration system;.
- Soda plant: forced circulation of ammonium chloride in evaporator and crystallizer;
- Paper mill: forced circulation of waste water in evaporator;
- The light industry: alcohol concentration, citric acid evaporation and sugar syrup evaporation and concentration.
Main features of HSDFC pump:
- Good anti cavitation performance: suitable for low level evaporator, large radiance to reduce the investment of evaporation plant. It is also applicable to the new type evaporator (reverse circulation evaporator, double heating chamber series
- High efficiency and wide high efficiency area: Change the angle of the blade and change the speed to meet the user's demand for flow and lift, and to make the operation of the pump in the high efficient area of the pump, the energy saving effect is remarkable.
- Slow speed type: the pump runs smoothly; the overcurrent is worn light, long life; lower crystal breakage, suitable for evaporation crystallization process;
- Cantilever rotor: compared with the double support, the number of shaft seal is halved, the weight of the pump is light, the size of the shape is small, and the maintenance is convenient;
- Pump body center support: Compared with the pump body foot support type, rotor thermal neutral;
- Back opening structure: The rotor can be pulled out without dismantling the inlet and outlet flanges of the pump body, which is convenient and quick to repair.
- Advanced shaft seal: With new type mechanical seal, the service life is 6~12 months; With a new type of liquid blocking packing seal, the life is 3~6 months;
- No need expansion joints of the evaporator: can provide elastic pump base or suspension type pump, the heat compensation is reliable, reduce the investment of evaporator.
- Higher reliability: High strength of pump shaft and bearing; the bearing seat is equipped with water cooling sleeve; With longer lifetime shaft seal; all ensure the long-term operation
- Direct connection: pump and motor are connected directly through a flexible coupling.
- Belt drive: it is easy to change the speed and adjust the performance of the pump through the transmission of the triangle belt.
