Exercise and Kim.

Mines need two main groups of pumps: pipe drainage pumps and mining holes, and water supply pumps, circulating for mineral collection. Mining water usually contains fine solid particles, which can be acidic and high temperature.

High pressure, many floors

The exhaust water from hundreds of meters depths must be pumped up by level. Multi-layer centrifugal pump for large pressure columns in compact texture, combining transmission pump stations according to each extraction level.

Wearing and corrosion.

• Solid seeds wear wings and pump covers: use high chrome gangs or wear resistant materials, while reducing the speed of rotation.
• Acid mineral water: use stainless steel or alloy steel, regular pH check.
• Mechanical sludge needs clean water (flush) so that solid particles do not get into the sludge.

NPSH and Hole

The water level in the tunnel hole of the oven changes, it is necessary to inspect the pumping equipment with sufficient NPSH or use submersible pump, standing pump to avoid invasion.

Maintain according to condition.

The harsh environment leads to the rapid opening of the wire, gradually decreasing performance. Measure the flow and pressure columns periodically to know when the wire or wing needs to be replaced, instead of waiting for the pump to break during the rainy season.
