Sediment and Drainage Handling

What it is:
Sediment and drainage systems control silt and debris accumulation in pits, ditches, and tunnels. Effective sediment management keeps water channels open and prevents flooding that can halt operations.

Challenges:
Settled solids compact quickly, making them hard to remove. Standard pumps clog or lose suction when sediment layers become too dense. Manual removal is labor-intensive and dangerous in confined areas.

Solution:
Hevvy/Toyo agitator pumps keep solids suspended and moving, preventing buildup. Their recessed impellers handle coarse and fine particles without clogging, providing full sump cleanout with minimal labor or downtime.

Mine Water Transfer and Runoff Control

What it is:
Mine water transfer systems move runoff, seepage, or drainage from working areas and haul roads to holding ponds or treatment facilities. They play a key role in water management, ensuring safety and environmental compliance.

Challenges:
Runoff water often carries suspended solids and fine sediments that abrade impellers and piping. Flow rates vary widely with weather conditions, and chemical contaminants can accelerate corrosion. Maintaining long-term reliability in exposed outdoor installations is challenging.

Solution:
Hevvy/Toyo pumps are built for high-volume transfer of abrasive and corrosive water. Their rugged wet ends, efficient hydraulics, and corrosion-resistant materials ensure consistent operation and extended service life in demanding water management systems.

Pit Dewatering Sumps and Wells

What it is:
Mines require continuous dewatering to control groundwater inflow and rainfall accumulation. Sumps and wells are strategically placed to collect water and slurry from active pits, drifts, or tunnels and pump it away to maintain safe and efficient working conditions.

Challenges:
Mine water often contains abrasive solids, corrosive elements, and fluctuating flow levels. Traditional dewatering pumps suffer from rapid wear, seal failure, or suction loss when solids settle or when wells are deep and remote. Consistent, unattended operation is difficult to maintain with standard equipment.

Solution:
Hevvy/Toyo submersible and vertical cantilever pumps are designed for harsh dewatering environments. With high-chrome or stainless-steel wet ends, agitators to prevent solids settling, and heavy-duty seals, they deliver reliable, low-maintenance performance in deep sumps and wells.
