Automatic Coupled Submersible Sewage Pump

A heavy‑duty automatic coupled submersible sewage pump system engineered for reliable, no‑dive manual installation and continuous wastewater handling in municipal, commercial and industrial settings.

Key features

• Automatic coupling installation system: fast interface, drainage base, guide rail and guide‑positioning bracket form a guided mounting system that secures the pump quickly and precisely.
• Simple installation sequence: the drainage base is anchored to the sump; the pump body is bolted to the fast interface and lowered along the guide rail until the automatic‑coupling sealing surfaces engage.
• Reliable sealed connection: pump outlet flange mates with the drainage base inlet flange and a rubber sealing ring forms the wet seal. The coupling relies on the pump’s own weight to maintain sealing pressure and pipeline integrity.
• Solids‑handling impellers: available with single‑flow or double‑flow channel impellers to handle liquids containing solids, fibers and other impurities while reducing clogging risk.
• Automatic operation: designed for non‑blocking performance, automatic installation and integrated automatic control for dependable duty in continuous or intermittent service.

Typical applications

• Municipal and construction site drainage
• Residential wastewater discharge
• Sewage handling for hospitals and hotels
• Urban sewage treatment plant drainage systems
• Civil defense drainage and waterworks supply systems
• Discharge of heavily polluted industrial and commercial wastewater

Benefits for B2B buyers

• Speeds installation and commissioning in pump stations and wet wells
• Minimizes alignment and sealing errors thanks to guided automatic coupling
• Suitable for heavy solids and fibrous content common in sewage and industrial effluents
