Industry
Mining
Dewatering, slurry transfer, and mine services water systems.
Mining operations impose extreme demands on pump equipment — high solids content, remote locations, explosive atmospheres, and the cost of any unplanned shutdown measured in tonnes per hour of lost production.
Industry Challenges
What makes mining applications demanding
High-solids slurry handling
Mine process water and slurry contain abrasive particles that rapidly wear impellers, mechanical seals, and valve seats.
Remote and underground installation
Equipment must be compact for shaft lowering, built for low-maintenance operation, and engineered for the constraints of underground access.
Explosive atmosphere (Ex) requirements
Underground mines require Ex-rated electrical equipment compliant with AS/NZS 60079 for Zone 1 and Zone 2 hazardous areas.
High discharge pressure
Dewatering from depth requires pumping against significant static head. Systems must be engineered for high-pressure duty with appropriate pressure relief.
Mining dewatering skid — high-pressure configuration with acoustic enclosure provision
RDJ Engineering Solutions
How we solve these problems
Abrasion-resistant component selection
Hard-faced impellers, ceramic-lined pipework, and tungsten carbide mechanical seals specified for high-solids slurry service.
Components involved
Compact skid design for underground
Skid footprint engineered within shaft cage dimensions. Modular design allows disassembly for lowering and reassembly underground.
Components involved
Pressure relief and overpressure protection
Spring-loaded pressure relief valves set to protect pipework and pump at maximum discharge head. Rated for high-pressure mining service.
Components involved
Duplex strainer — online cleaning
Duplex basket strainers allow one basket to be cleaned online while the other remains in service — essential for uninterrupted dewatering.
Components involved
Acoustic enclosure
Modular acoustic enclosures reduce pump noise to meet underground noise exposure limits and surface environmental requirements.
Components involved
Flow and pressure monitoring
Electromagnetic flowmeters and pressure transmitters provide real-time dewatering data for mine water management and pump protection.
