Industry Challenges

Feedwater pumps, circulation pumps and other key equipment in power plants run at high speed under continuous load; once seals or rotor components fail, plant safety is directly threatened. Imported spare parts have long procurement cycles and high prices, while maintenance windows are fixed and tight, placing exacting demands on interchangeability and reliability.

SuFu Solution

For high-speed service we provide localization of mechanical seal spare parts and rotor assembly repair — dimensionally interchangeable with OEM parts, they replace imports quickly and shorten downtime. Advanced sealing materials such as silicon carbide and PEEK together with proven processes extend component life, helping plants stretch maintenance intervals and reduce spare part procurement costs.

Services & Typical Scenarios

We provide complete services including impeller and rotor balancing plus post-repair test runs to ensure reassembly quality, and can take on bulk spare parts and on-site service demand in peak maintenance season. Our six-location network — Suzhou, Shanghai, Dalian, Jinzhou, Tianjin and Guangxi — safeguards nearby spare part allocation and staff dispatch, supporting long-period stable operation of thermal, cogeneration and combined-cycle units.
