Heavy Duty Dewatering Pump – The Future of Open Pit Mine Dewatering

Type WRXW is a pump with robust highly wear and chemical resistant dewatering centrifugal pump for high flow and high head. Bom out of our toughest dredge pump.

• Pumping of abrasive and corrosive liquids with up to 50mm grain size.
• Axial suction and tangential discharge flanges
• Casing is rotatable in 22,5° steps
• Efficiency > 80%
• Application: Open Pit Mine Dewatering
• Option: Diesel Engine & Electric Motor
• Durable, grease lubricated bearings with automatic lubricator (optional oiul circulation lubrication available)

Extremely high abrasion and corrosion resistant

A mineral cast pump (Type MC) is designed for heavy-duty mining and process industry applications. The pump uses composite material based on epoxy resin and mineral aggregate. The structure is non-porous and homogeneous. This characteristic improves resistance against chemical penetration.

Mineral cast material provides excellent corrosion resistance. Aggressive chemicals do not damage internal structures. The pump operates reliably under extreme pressure and temperature. Performance remains stable during continuous duty.

• Pumping of abrasive and corrosive liquids
• All components which are in contact with the liquid are made of SICcast®
• Discharge flange: Top (Vertical)
• Nominal pressure up to 10 bar (150 PSI)​
• Flow up to 1.500 m³/h (6,600 gal/min)
• High wear and corrosion resistance
  – pH-Values 0-13
  – Maximum Density up to 1,700 g/l
• Different designs available; Horizontal or Submersible
• Optimized design ensures easy maintenance and long service life even under difficult conditions

Our standard design for your individual dredging project

The established System 2002 is an extensively standardized suction dredger model featuring a light, compact design with high quality equipment as Standard features of the series includes an optimised suction pipe automation system, optional extras, and dredging pumps with nominal diameters from 200mm to 400mm. Despite the standardization, the configuration of your suction dredger is flexibly adapted to your specifications and requirements. The optimized arrangement of the assemblies reduces friction losses in the suction and pressure pipes, increasing the amount of solid material dredged.

Performance

• max. conveying distance 500 m
• max. conveying rate 25 m
• max. extraction depth 1000 tph
• max. particle size 200 mm

The solution for major dredging projects

The System 3000 suction dredgers are available with our dredging pumps in nominal diameters of 200mm to 400mm. The System 3000 was initially developed for our own contract dredging business. The technical requirements were therefore designed by our experienced dredger experts and tested in practice. The special feature of System 3000 is its two central pontoons, which are accessible on foot. The dredging pump, which sits approximately 1 meter below the waterline, can be started at any time without being primed first. The cross-section of the catamaran pontoon is generously dimensioned, ensuring that plenty of space is available here for machinery, switch cabinets, transformers and a workshop.
