Mining Under Suction Submersible Water Pump
This pump is widely used for the irrigation for agricultural land, the water supply and sewage for industrial and mining enterprises, and the water utilization for the people and animals in altiplano and mountain area.
1. Working Parameters
(1). Flow range 10-500m³/h
(2). Lift range 10-600m
(3).Caliber range:32-203mm
(4).Temperature:-15~80 degree
2. Product Overview
The self-cooled, high-lift and downdraft suction type pumps adopt water-filled wet type well use submersible motor,
the empty cavity between the motor shell and the protect tube is used as water channel, which can make the motor get sufficient cooling, and also make the submersible pumps have good cooling conditions, long servise life, high efficiency, simple structure and low cost.
This national patent, tube protect and downdraft suction type pumps with high power, big flow, high-lift are designed
especially for rescuing drainage under coal well. It can drain the mine water away completely . Furthermore, it has
reasonable structure, high efficiency . In addition, it is energy saving, convient to assemble and maintain, reliable to
use, etc.
