Submersible Sewage Pumps for Mining Wastewater

Mining sites can have difficult drainage conditions. Water may collect in pits, underground areas and process zones, often carrying suspended solids. A submersible pump can be installed directly at the collection point, reducing the need for long suction arrangements.

Mining Among the Listed Applications

The supplied WQ/QW material lists mining among the industries where these pumps are used. The single-channel or twin-channel impeller is designed with a relatively open flow path for wastewater containing solids and fibers. This is useful where blockage is a concern.

Liquid Properties Need Close Attention

Mining applications require more attention to liquid properties than a simple drainage job. The presence of abrasive solids, unusual density or corrosive chemicals can influence material selection and pump life. The manufacturer should therefore receive information about the liquid, solids concentration, temperature and any chemical content before final selection.

Mechanical Protection

Mechanical protection is also relevant. The referenced design uses a double mechanical seal and hard, corrosion-resistant tungsten carbide seal material. An oil chamber and leakage sensor can help identify seal leakage before the motor is affected. Thermal elements in the stator winding can provide additional motor protection.

Installation at the Mine Site

Installation conditions can vary greatly at a mine. A mobile arrangement may be useful when the pumping point moves as excavation progresses. A fixed guide rail system is more suitable for a permanent drainage station. The choice should be based on how often the pump needs to be moved and how the discharge piping is arranged.

Electrical Supply

Where the mine uses 415 V, 50 Hz electrical supply, that motor configuration can be requested as part of the customization. The motor power should be selected from the actual flow and head requirement, with the control cabinet designed for the same electrical system.

Stay Within the Intended Head Range

The source documentation also recommends using the pump within its intended head range and avoiding prolonged operation at an unsuitable low head. Correct system design is therefore important.

A pump that works in one pit will not automatically work in the next one down the road. Site conditions are worth stating even when they seem obvious.
