Market Pain Points & Upgrade Philosophy

Most conventional sewage lift controllers on the market use low‑cost general‑purpose chips, which have clear drawbacks: lagging computation, frequent malfunctions in humid environments, limited networking scalability, and high failure rates during long‑term operation. These issues often lead to costly consequences, including basement flooding, pump burnout, and soaring operation and maintenance expenses.

Five Core Advantages of STM32‑Powered SL Series

All SL-T21&22/T/Q and SL31&32/F/Q intelligent sewage lift units from Hunan Leading Technology come standard with STMicroelectronics STM32 main control chips and the ST Purple Ming Platform V13.0. Drawing on ST’s decades of experience in industrial chip R&D, the products feature five core advantages that address the industry pain points of conventional controllers — such as stuttering, misjudgment, frequent failures, and poor expandability.
