Where High-Head Dewatering Pumps Perform
Built for abrasive slurry transfer where seal wear, solids loading and maintenance downtime are common issues. 
Best suited for:
  • Open-cut mine dewatering
  • Quarry pits and collection sumps
  • Deep benches and low-point drainage
  • High-lift water removal from active workings
Selection considerations:
  • Confirm total head, including elevation and pipe friction
  • Review suspended solids, abrasion and water characteristics
  • Check discharge routing, power supply and lifting access

 
Mine-1
 For open-cut mine and quarry duties where high lift, rugged construction and dependable dewatering are required.
Contact Your Pump Expert
Peristaltic hose pumps integrated into complete dosing, batching, and process skid systems. 
Best suited for:
  • Long rising mains and discharge pipelines
  • High-elevation water transfer
  • Remote discharge points
  • Duties beyond the head capability of standard dewatering pumps
Selection considerations:
  • Confirm total dynamic head and the complete system curve
  • Check pipe diameter, pressure rating and friction losses
  • Match the pump, starter or VFD arrangement to the operating duty
Mine dewatering pit
 For high-head transfer duties where elevation and long discharge pipework create significant system pressure.
Contact Your Pump Expert
Reliable for sludge feed, polymer dosing, digester systems, and dewatered solids transfer. 
Best suited for:
  • Deep civil excavations
  • Tunnel and underground infrastructure projects
  • Construction shafts and major site sumps
  • Large-scale construction dewatering
Selection considerations:
  • Confirm expected inflow and required pump-down rate
  • Calculate static lift, pipe losses and discharge distance
  • Consider standby capacity, access and operating controls
Industrial access shaft from above-1
 For major excavation and tunnelling projects where substantial lift and reliable site dewatering are critical.
