Tough Pumping Solutions for Harsh Mining Environments

In the mining industry, pumps are essential for dewatering mines, managing process water, and transporting abrasive slurries. However, these demanding applications present significant challenges that can lead to frequent breakdowns, high maintenance costs, and operational downtime.

Mining operations run around the clock in some of Canada’s most remote and demanding environments. Pump failures can halt production, flood mine shafts, or disrupt critical water treatment systems — leading to costly downtime and safety risks.

Key Pump Challenges:

Abrasive and Corrosive Media

This is the most prevalent challenge. Pumps in mining applications handle a combination of water, sand, rock particles, and chemicals used in mineral processing. These abrasive slurries cause rapid wear and erosion on pump components like impellers, casings, and seals.

Mechanical Failures

The harsh operating environment can lead to a variety of mechanical issues. These include bearing failure due to heavy loads, seal leaks causing fluid contamination, and motor overheating from running dry or being overworked.

Clogging

Fibrous materials, large solids, and debris can cause pump impellers to clog. This leads to reduced flow, increased energy consumption, and can cause a complete pump shutdown if not addressed quickly.

Energy Inefficiency

Pumping is a major energy consumer in mining. Abrasive wear on pump components reduces efficiency over time, leading to higher electricity bills and a larger carbon footprint.

Unpredictable Conditions

Mine dewatering pumps, in particular, face constantly changing conditions, including fluctuating water levels and varying concentrations of solids. These unpredictable demands make it difficult to operate a pump at its most efficient point.

Nevtro’s Approach

Material Selection

Using wear-resistant materials is a fundamental solution. Pumps designed for mining are made from high-chrome alloys, hardened steel, or are lined with rubber or polyurethane to resist abrasion and extend component life.

Solids-Handling Impellers

Pumps for slurries are equipped with specialized impellers that are designed to pass large solids without clogging. Recessed or vortex impellers are often used to create a clear passage for debris.
