The diaphragm pump industry is enhancing product competitiveness through technological innovation and environmental standard certification. Recent patent information reveals that a piston structure for coal slurry transport diaphragm pumps utilizes an integrated positioning platform to ensure the perpendicularity of the piston disc, effectively preventing hydraulic oil leakage and improving equipment reliability and operational efficiency. Meanwhile, a patented technology for dual-chamber diaphragm pumps with control valves achieves higher pumping pressure by transmitting greater torque through a crankshaft assembly and piston-connecting rod mechanism.

China's high-end equipment manufacturing sector has recently achieved significant progress. China Nonferrous Metals Industry Pump Co., Ltd. has successfully completed the trial operation of the first DGMB400/18A triplex single-acting diaphragm pump designed for a nickel-cobalt hydrometallurgical project in Indonesia. The project imposes extremely stringent requirements on flow rate, pressure, and reliability for slurry transport equipment, and such ultra-large diaphragm pumps have long been dominated by a few European and American companies.

Recent market research indicates that the global diaphragm pump industry is experiencing steady growth. Data shows that the global revenue scale for diaphragm pumps was approximately RMB 9.036 billion in 2025 and is projected to approach RMB 14.56 billion by 2032, representing a compound annual growth rate of 7.1%. This growth is primarily driven by sustained demand from downstream sectors including water treatment, chemicals, oil and gas, and food and beverage.
