Sinopec Zhenhai Refining | High-Efficiency KQSN Double Suction Pump – Kaiquan

Shanghai Kaiquan Pumps Group supplied 10 specialized units of its high-capacity KQSN Double Suction Centrifugal Pumps for Sinopec Zhenhai Refining & Chemical Company, one of Asia's largest integrated mega-refining and petrochemical bases.

Engineering High-Flow Efficiency for Mega-Refineries

Continuous fluid circulation and cooling water supply are critical to maintaining process stability, thermal balance, and operational safety across world-scale refining complexes. To satisfy Sinopec Zhenhai's stringent performance requirements, Kaiquan deployed custom-engineered KQSN double suction pumps built for low-speed, high-volume fluid displacement.

Technical & Operational Benchmarks

Massive Flow Capacity: Delivers high flow rates between 6,500 - 7,000 m³/h at a 10 -13m head, operating at a low, stable speed of 590 r/min.

Industry-Leading Efficiency: Reaches an outstanding hydraulic efficiency substantially reducing energy consumption for large-scale continuous pumping.

Optimized Power Consumption: Equipped with 315 kW to 355 kW motors, delivering high operational economy and minimizing lifecycle costs.

Combining superior hydraulic design with low vibration and long service life, Kaiquan’s KQSN double suction pumps provide Sinopec Zhenhai with unyielding equipment reliability and optimized energy efficiency for its refining infrastructure.
