Full Range of Material Selection

1.Materials for Core Flow-passing Components

1.SUS304 Stainless Steel (Standard General Model)

Impellers, diffuser casings, pump shafts and discharge sections are all made of SUS304 stainless steel, complying with sanitary standards for domestic drinking water. It is suitable for ordinary clean underground water and domestic tap water from deep wells, widely adopted in domestic agriculture, forestry and municipal projects.

2.Corrosion-resistant SUS316L Stainless Steel

With molybdenum element added to resist corrosion caused by chloride ions, saline-alkali well water and coastal seawater wells. It is specially designed for saltwater wells on islands and coastal zones.

3.Economical Cast Iron Deep Well Pump

The cast iron impeller is coated with anti-corrosion layer, which is only applicable to clean non-corrosive ordinary well water and extensive agricultural irrigation.

4.Duplex Stainless Steel 2205

Specially used for deep wells with high mineralization, severe saline-alkali environment and seawater deep wells.

Working Principle
1. The entire pump unit is submerged in deep well water. Once powered on, the submersible motor drives internal multi-stage impellers to rotate at high speed.
2. Spinning impellers apply mechanical work to well water. Under centrifugal force, water gains kinetic energy and hydraulic pressure, with pressure boosted sequentially through each impeller stage.
3. Pressurized water converges through the pump’s internal flow channels and is delivered upward to ground pipelines or storage facilities via riser pipes.
4. The matched electric control system enables automatic startup or shutdown based on water level and pressure feedback signals. It will cut off power automatically under water shortage or overload conditions to avoid motor burnout caused by dry running.
