LC Single‑Tube Long‑Shaft Submerged Deep-Well Pump

Working Principle A NEMA‑standard outdoor motor drives submerged impellers via long‑shaft flexible coupling for centrifugal pressurization. The pump suction points downward with horizontal top discharge. Radial vanes reduce vibration; upper thrust bearing takes axial load while lower sleeve bearings are fluid‑self‑lubricated. Mechanical seal or packing seal options prevent leakage. Applications Deep-well groundwater extraction & municipal / industrial water supply Chemical corrosive fluid and waste liquid transfer Wastewater sump lifting for tanks and basins Mining dewatering and metallurgical process circulation General‑service pumping for clean water and compatible media
