The metallurgical industry is the basic industry in China's heavy industry. We took the lead in applying GR series screw pumps in the metallurgical industry. This series effectively solves the problem of poor coaxiality and difficulty adjusting of the original screw pump through the installation of bell cover connection, prolongs the life of oil pumps, reduces the difficulty of on-site installation and maintenance, and saves valuable maintenance time for users. Helnco's SN and other series of three-screw pumps are widely used in the metallurgical industry, successfully replacing imported and other similar oil pumps. It is also unique in performance, and there are significant improvements in common problems such as seal leakage and noise. It has long maintained close cooperation with major steel mills, such as Baosteel, Wuhan Iron and Steel, Taigang, Shougang, etc. It has been widely used in hot rolling, cold rolling, circulating cooling systems and dilute oil lubrication systems of bars and wires.
