Let’s give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】A continuously updated summary post is available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** Recently, the high-efficiency, intelligent submersible pump for concentrated sulfuric acid, developed by Kunming Jiahe Technology Co., Ltd., was included in the China Petroleum and Chemical Industry Federation’s “List of Advanced Processes, Technologies, and Equipment for the Transformation and Upgrading of the Petrochemical Industry (2025 Edition)”. 　　This highly efficient and intelligent submersible pump for concentrated sulfuric acid is a single-stage, single-suction, axially-inflowing, radially-separated submersible centrifugal pump. It is suitable for use in systems for transporting sulfuric acid, as well as in processes such as sulfur-based acid production, waste acid recovery, acid production from zinc and lead ores, and acid production from flue gas. It can handle sulfuric acid with a temperature of ≤120°C and a concentration of 93%–98%, or fuming sulfuric acid with a concentration of ≥105%. The pump can operate at a pressure of 2.0 MPa, with a flow rate of 3520 cubic meters per hour, and its head capacity reaches 120 meters. This pump utilizes a number of proprietary technologies developed by Jiahe Technology, enabling it to achieve a power savings rate of 20%-50%, which is superior to the **first-level energy efficiency standard. It features energy and carbon reduction, intelligent upgrades, long operational life, and maintenance-free operation for customers. It has been awarded titles such as **Key New Product**, **Excellent Patent Award**, and Yunnan Province’s Single Champion Product, and has also been included in lists of **key cases for the application of energy-saving technologies** as well as **recommended products for energy-saving and carbon-reduction technologies and equipment**. 　　It is understood that the high-temperature concentrated sulfuric acid submersible pump was developed by Jiahe Technology as early as the 1990s. From the successful use of the first high-temperature sulfuric acid submersible pump, the JHB400-30, in Yunnan in 1998, to the replacement of imported pumps with the large-scale high-temperature concentrated sulfuric acid submersible pump JHB1400-22 in 2004, thereby filling a gap in domestic production; from the successful commissioning of a world’s largest sulfur-based sulfuric acid production project in Indonesia in 2023, to the use of the world’s most high-flow concentrated sulfuric acid submersible pump, the JHB2300-24; and then the acquisition of China’s first carbon-neutral pump certification in June 2022 – Jiahe Technology’s efficient and intelligent high-temperature concentrated sulfuric acid submersible pumps have undergone continuous technical upgrades, paving a path of independent innovation in the field of special industrial pumps. 　　To date, Jiahe Technology’s high-efficiency, intelligent submersible pumps for high-temperature concentrated sulfuric acid have been used by over 1,000 customers in China’s industrial sector; the company holds a market share of more than 80%, ranking first in this field. With its high-quality equipment, excellent professional capabilities, and efficient service standards, it has won widespread acclaim from businesses.
