The " GIDROZUB PD" unit is a centrifugal pump that can pass not only a mixture of soil and liquid, but also large block parts. This single-stage sand and soil pump is designed for installation on various models of hydraulic excavators. The dredger is powered by the excavator's hydraulic mechanisms and does not require the purchase of a separate, expensive hydraulic power plant. Connecting the unit to an excavator makes it easier to control the device and make it more mobile.

Sludge pump " GIDROZUB PD" is designed for suction of soil from under water, as well as for the subsequent transportation of the soil mixture (hydro-mixture) through special pipelines.


Areas of use:

  • dredging works;
  • extraction of sand from flooded quarries;
  • transportation of sand and other inert materials;
  • dewatering of pits for construction purposes;
  • transport of mining waste;
  • clearing of sumps from industrial waste, sludge and dirt;
  • transfer of scale from sewage pits with their subsequent cleaning;
  • cleaning of caissons in the construction industry;
  • removal of excess silt in pressure basins, port area, etc;
  • control and rehabilitation of coastal erosion;
  • Transportation of mixture of soil and water from the wells of ball mills and tunnels.
