Where Standard Submersible Dewatering Pumps Perform

Built for abrasive slurry transfer where seal wear, solids loading and maintenance downtime are common issues. 
Built for abrasive slurry transfer where seal wear, solids loading and maintenance downtime are common issues. 
Best suited for:
  • Construction-site dewatering
  • Excavations and trenches
  • Temporary drainage sumps
  • Stormwater and dirty-water removal
Selection considerations:
  • Confirm required flow, head and pump-down rate
  • Check suspended solids and abrasion levels
  • Consider portability, hose layout and available power supply
Civil Site
 For portable construction-site dewatering where durability, abrasion resistance and reliable water removal are required.
Built for abrasive slurry transfer where seal wear, solids loading and maintenance downtime are common issues. 
Best suited for:
  • Concrete batching plants
  • Industrial process-water removal
  • Washdown and collection sumps
  • Dirty water containing suspended fines
Selection considerations:
  • Confirm liquid characteristics and abrasive content
  • Match the pump to operating hours and duty cycle
  • Check solids passage, discharge conditions and maintenance access
Concrete facility-1
 For concrete and industrial dewatering duties where suspended fines, abrasion and frequent operation must be considered during pump selection.
Built for abrasive slurry transfer where seal wear, solids loading and maintenance downtime are common issues. 
Best suited for:
  • Underground tunnels
  • Construction and industrial sumps
  • Trenches and confined drainage points
  • Underground and basement carparks
Selection considerations:
  • Check sump dimensions, access and lifting requirements
  • Confirm low-water-level and operating-time requirements
  • Review ventilation, electrical supply and discharge routing
Industrial access shaft from above-1
 For confined or below-ground dewatering where compact installation, low-water-level operation and dependable pumping are important.
