A "special gift" received by JIAHE---a certificate of use from a customer, which explains that the JHB high-temperature concentrated sulfuric acid submersible pump provided by Jiahe for the localization transformation of the drying tower circulating pump and the first absorption tower circulating acid pump in the customer's waste acid regeneration device successfully replaced the imported pump.

Since its investment in 2022, the equipment has been in good condition, and all indicators have met the technical requirements, which perfectly solves the "bottleneck" problem of localization substitution of special pump equipment for customers.

There are many corrosive media in the waste acid regeneration device, and the anti-corrosion performance of the equipment is very high. For a long time, imported pumps have been used in this working condition in China. Jiahe has become the preferred partner for customers' transformation and replacement with its technical strength in the special pump field for nearly 30 years and its rapid response service mechanism.
