Deep Well Irrigation Submersible Screw Pump

The TRUPOW Deep Well Irrigation Submersible Screw Pump is a positive displacement pump that operates completely submerged in water. Its core advantage lies in the organic combination of a sealed electric motor and a single-screw pump section, overcoming the installation and operational limitations of traditional deep well pumps. As a supplier specializing in fluid equipment, TRUPOW, with its mature production technology, ensures that this pump features a compact structure, stable operation, and wide adaptability, allowing it to operate reliably in various complex water extraction scenarios and efficiently transport groundwater and other clean water sources.

Core Structure and Working Principle

1. Overall Structure

The pump mainly consists of a submersible electric motor, a single-screw pump, and a sealing device. It adopts a "motor below, pump body above" layout, with the motor completely submerged in water, significantly improving heat dissipation and preventing motor overheating damage. The motor can be a single-phase or three-phase asynchronous motor, available in dry or oil-filled structures to suit different power requirements; the sealing system uses a combination of "O" rings and double-face mechanical seals to ensure reliable sealing performance and extend equipment service life.

2. Working Principle

The single-screw pump is the core water delivery component of the Deep Well Irrigation Submersible Screw Pump. It consists of a single helical elastic rubber stator and a rotor. When the rotor rotates, a continuously changing sealed chamber is formed between the stator and the rotor. This chamber carries the liquid being transported, drawing it in from the inlet and gradually pushing it along the helical direction of the screw to the outlet, achieving smooth and continuous liquid transport without pulsation or leakage, making it ideal for efficient transport of clean water sources.

Application Scenarios

The TRUPOW Deep Well Irrigation Submersible Screw Pump is designed for pumping clean water and is suitable for a wide range of applications, mainly including:

- Deep well water extraction: Efficiently extracts groundwater from deep wells, solving the problem of deep groundwater extraction;

- Agricultural and horticultural irrigation: Suitable for irrigation of farmland, orchards, and gardens, providing a stable water source for crop growth;

- Domestic and engineering water supply: Can be used for domestic water supply in towns and villages, as well as temporary or long-term water supply for urban construction, factories, railways, and other engineering projects;

- Other scenarios: Can also be applied to water lifting projects from rivers, reservoirs, and canals, as well as mine drainage and light industrial drainage.
