Deep Well Pump

Sinoflo deep well pump is an important water lifting tool that is directly connected to a motor and a water pump for submerged operation. It is widely used for extracting groundwater from deep wells and can also be used in water lifting projects such as rivers, reservoirs, and canals. Mainly used for irrigation of farmland and water supply for humans and animals in high-altitude mountainous areas, it can also be used for drainage in cities, factories, railways, mines, and construction sites.

Structural Characteristics

Submersible Pump Structure
Single-suction multistage centrifugal design, comprising pump bowl, impeller, sealing ring, conical sleeve, pump shaft, inlet section, and check valve.
Submersible Motor Structure
Water-filled three-phase asynchronous motor, including stator, rotor, guide bearing seats, sand-proof ring, and pressure regulating membrane.
Key Design Features
✓ Pump and motor directly coupled via sleeve-type coupling.
✓ Upper/lower thrust bearings with thrust discs handle bidirectional axial loads and rotor weight.
✓ Rubber pressure-regulating membrane compensates for thermal expansion/contraction of internal water.
✓ Motor chamber must be pre-filled with clean water; all ports sealed leak-tight before operation.
Safety & Sealing
Reliable sealing ensures long-term stable submersion performance.
