Application of PVDF Self-priming Pump in the Field of Acid and Alkali Production

Application of PVDF Self-priming Pump

  The production of acid and alkali industry usually faces two problems: how to transport acid and alkali and the other is how to store acid and alkali.

  The traditional method uses stainless steel as the lining of the submerged pump and the reaction tank to transport and store the acid and alkali liquids.

  A long-axis cantilever structure characterizes the stainless steel submersible pump. It can penetrate below the acid and alkali medium to be transported for low-level transport. However, the lift cannot exceed two meters at most; otherwise, You will significantly reduce the work efficiency. Moreover, the mechanical structure of the submerged pump itself is bloated. In conveying the medium, its various components (such as bearings at all levels) wear very seriously. Therefore, the failure rate of this kind of pump is very high. Its structure is complicated, the disassembly is inconvenient, and the maintenance is even more troublesome. Usually, a pool or a line should be equipped with two submerged pumps. One pump is used, and the other is used—one pump for backup.

  The PVDF self-priming pump solves the shortcomings of the stainless steel vertical pump and the poor structural reliability. First, the PVDF F46 is used as the lining, and the corrosion resistance is much improved compared with the submerged pump. At the same time, it can be sealed in the conveying medium, thereby preventing leakage and leakage. Secondly, the maximum lift of the PVDF self-priming pump is much higher than that of the submerged pump. According to the motor's power, its lift range is about 2-8 meters. In addition, the overall structure of the fluoroplastic self-priming pump is developed and designed with advanced international technology. The system is light and reliable, easy to disassemble, and easy to maintain and maintain. Compared with the traditional submerged pump, the working efficiency and reliability of the fluoroplastic self-priming pump have been greatly improved, so the severe waste of one production line with two pumps is no longer necessary. The PVDF self-priming pump equipped with a high-power motor can drive the production of two lines with one pump.
