Circulation Oil Pump Successfully Commissioned at Sinopec Zhenhai Refining & Chemical

Recently, the 5.6 million tons/year residue hydrotreating unit at Sinopec Zhenhai Refining & Chemical successfully completed its first maintenance overhaul and resumed operation.

The circulation oil pump (Tag No. 0217-P-2200), independently designed and manufactured by Hefei Huasheng Pumps & Valves, was successfully commissioned as part of the project.

Operating under high-temperature and high-pressure conditions, the pump handles heavy residue containing high levels of sulfur and metals. To meet these demanding requirements, Hefei Huasheng Pumps & Valves provided a customized solution involving special material selection, structural optimization, and strict quality control.

The pump installation was completed on September 6, 2026, and it was successfully put into operation on September 17. All operating parameters met the design requirements.

This successful commissioning highlights HSPump's capabilities in the design and manufacture of specialized pumps for the petrochemical industry.
