Engineered for Australian Mining. The Dewatering Pump System That Actually Works.
Every mining operation faces the same relentless enemy: water.
Whether it’s groundwater seepage, stormwater accumulation, or slurry from processing, uncontrolled water ingress halts production, damages equipment, and creates safety hazards that cost millions. Traditional mining dewatering pump systems are too costly and too complex, with frequent maintenance interruptions.
The Solution: Liquimech Dewatering Pump Systems
We design and build complete mining dewatering pump systems engineered for Australian mining conditions: from the Pilbara to the Hunter, underground to open pit. Our mining dewatering pump system solutions are built to solve the problems others ignore.

The Hidden Costs You’re Paying Right Now
| Your Pain Point | The Real Cost |
|---|---|
| Premature pump burnout | Solids and abrasives destroy standard mining dewatering pumps in weeks, not years |
| Unplanned downtime | Every hour of lost production is revenue you’ll never recover |
| Sediment build-up | Tailing dams fill faster, sumps require constant cleaning |
| Safety incidents | Flooded working areas, unstable ground, equipment damage |
| Compliance breaches | Environmental regulations are getting stricter, not looser |
The real cost? Mining operators spend millions on mining dewatering pump systems that fail prematurely. Downtime isn’t just inconvenient, it’s expensive.
Why Liquimech?
| Your Challenges | Our Solution |
|---|---|
| Pumps fail from solids and abrasives | Semi-open impellers handle solids up to 76mm: sand, gravel, debris pass right through |
| Downtime costs millions | Vacuum-assisted self-priming: starts fast, stays primed, no manual intervention |
| Site access is limited | Modular configurations: Canopy, Skid, POD, or Trailer-mounted for any site layout |
| Slimes destroy equipment | Oil-free diaphragm vacuum pumps: dry-run safe, no contamination |
| Maintenance takes too long | Hinged cover access: direct impeller access without lifting gear |
| Remote sites lack power | Diesel-powered: reliable, fuel-efficient, no grid connection needed |
| Sediment destroys pumps | Patented vortex separation: removes solids at the source |

|---|---|---|---|---|
| PAS MF | 45 – 150 | 19 – 37 | 40 – 76 | Heavy-duty mining dewatering, mine sites, abrasive water |
| VAR | 50 – 96 | 33 – 40 | 50 – 76 | Construction, general dewatering, flood response |
| PAC H | 42 | 92 | 20 | High-head, long-distance water transfer |
| AV50 | 16.7 | 20 | 28 | Hard-to-reach areas, confined spaces |
| Transfer | 22 – 56 | 15 – 25 | 27 | Fuel transfer, site water supply |
Built for What You Pump
- Sand and slurry? Semi-open impellers handle it
- Abrasive water? Cast iron with replaceable wear plates
- Variable water levels? Vacuum priming, no foot valve needed
- Remote operations? Diesel engines, electric start, large fuel tanks
Underground Dewatering: The Unique Challenge
Underground mine dewatering is critical for both safety and profitability. Limited space, power constraints, and location complexity make it one of the most challenging applications in mining.
Key Underground Challenges:
- Slimes: A collection of drilling dust, dirt, and shotcrete fibres that cause premature pump burnout
- Space constraints: Tight access, limited installation areas
- Daisy-chained systems: Multiple pump stations linked up the decline
- Sediment build-up: Constantly flushing hoppers to avoid upstream issues
Our Underground Solution
Liquimech’s patented underground mining dewatering pump system uses a vortex separation system that:
- Begins separating contaminants the moment water enters the unit
- Pushes particles larger than water to the outermost area of the reverse cyclone
- Uses gravity and friction to produce peak settlement time
- Ensures only the cleanest water moves to the next filtration stage
The system is automated, as soon as a pre-set sediment level is reached, valves auto-dump. No manual intervention, no unexpected failures.
Configuration Options
| Configuration | Best Use Case |
|---|---|
| Canopy | Weather protection, noise reduction, fixed installations |
| Skid | Ground or platform mounting, easy relocation |
| POD | Compact footprint, swing-out doors for service access |
| Trailer | Site-to-site mobility, rapid deployment for emergencies |
