The 25th National \"Safety Production Month\" in 2026: Everyone talks about safety, and everyone knows how to handle emergencies; identifying and addressing risks and hazards. -------------------------------------------------- Recently, Zhongse Pump Industry successfully completed the trial run of the first set of DGMB400/18A three-cylinder single-acting diaphragm pumps that it designed and manufactured for an Indonesian project involving the long-distance pipeline transportation of nickel-cobalt hydrometallurgical tailings and filtrates (hereinafter referred to as the \"Indonesian project\"). As a representative of the latest achievements in China’s high-end pump industry, this major industrial equipment is set to go global, playing a key role in providing essential equipment for the construction of green mines along the Belt and Road Initiative. The Indonesian project imposes extremely strict requirements on the flow rate, pressure, and reliability of slurry transport equipment. For a long time, such ultra-large-scale diaphragm pumps have been monopolized by a few companies in Europe and the United States. Zhongse Pump Industry successfully secured a one-time order for 12 DGMB400/18A three-cylinder single-acting diaphragm pumps for a project in Indonesia. During the R&D process, by optimizing the channel design and employing two-stage pulsation suppression technology, the equipment’s adaptability to complex media such as lateritic nickel ore slurry and tailings was significantly improved, while energy consumption and wear during transportation were effectively reduced. These 12 diaphragm pumps will be used directly for tailings treatment and long-distance transportation in Indonesia’s nickel mining projects, helping the clients achieve efficient, safe, and environmentally sustainable production goals.
