DONGGUAN HydroBlue CO.,LTD. is a technology-driven enterprise delivering integrated solutions in fluid machinery, fluid engineering, industrial automation, and variable frequency drive systems. Our team of 8 professionals specializes in fluid engineering, electrical engineering, and electronic engineering, bridging applied research and practical manufacturing. Close collaboration with Jiangsu University, Chinese Academy of Sciences, and Guangdong University of Technology keeps our capabilities at the leading edge in hydraulic development, specialty coating applications, and intelligent industrial drive technologies. Jiangsu University National Research Center of Pumps provides pump-drive coupling torsional stiffness matching and critical speed avoidance analysis for REXNORD coupling applications across multiple pump types; Chinese Academy of Sciences contributes advanced metallurgical process research for through-hardened gear coupling alloy steels and corrosion-resistant hub materials; Guangdong University of Technology supports precision spline cutting and spline gauge verification for close-tolerance coupling drive connections.
Provide your pump model and coupling specifications — our team will assess compatibility and come back with a detailed technical proposal.
Our brand delivers complete technical solutions within the fluid machinery and engineering sectors. Through our range of specialized technologies and product brands, we equip our clients with high-level technical advisory, commercial support, and integrated product solutions — covering pumps, frequency converters, servo drives, PLC-HMI, industrial control cabinets, motors, mechanical seals and assemblies, couplings, gearboxes, and turnkey engineering services (overseas on-site 3D scanning reverse molding of pump replacement parts and equipment debugging by our engineers deployed overseas).
