Product Description

Submersible pumps widely used in farmland irrigation, spray irrigation and water-use, industrial and civil buildings, also the drainage system to level hills, mountain diversion and in low-lying areas dunes, urban and rural mining supply, drainage and other water conservancy facilities. Characteristics are that they are assembled into a simple structure they have installation convenience a small footprint, simple maintenance and a safe reliable operation.
