This marks another breakthrough by Heavy Pump Company in breaking foreign monopolies as it strives to achieve the localization of high-end equipment. The high-pressure slurry diaphragm pump will be used in the tailings transportation pipeline with the highest pressure in a certain group in China. The pump has a designed flow rate of 280 m3/h and a designed pressure of 16 Mpa; it requires high technical standards and presents significant manufacturing challenges. After taking on this project, the Heavy Pump Company organized its technical team to work intensively on it, overcoming numerous technical challenges along the way. It developed its own high-pressure hydraulic end technology, casting technology for integral heavy-duty power end housings, and intelligent electromagnetic oil filling and drainage technology; at the same time, it also applied technologies such as unit synchronization. Test data from the trial runs show that not only do the pump set’s flow rate and pressure meet the design requirements, but the efficiency of the unit also exceeds 90%, with an outlet pulsation of less than ±0.5% – which is higher than the standard of ±1% to ±2% for imported equipment. Its technical specifications are at the international advanced level.
