KZ Series Sludge / Slurry

PDF datasheet mirror for KZ Series Sludge / Slurry (JS Pump). Verify with OEM before design.

Summary

Product identification

  • Product line: KZ/KZN SAND/SLUDGE/SLURRY PUMPS
  • KZ I SUBMERSIBLE SAND PUMPS
    • Applications: Ground and nuisance water removal; drainage from dams, sewer systems, tunnels, river improvement projects, construction sites.
  • KZN/SLUDGE/SLURRY PUMPS
    • Applications: Muddy liquid generated from civil engineering projects and architectural works; also suitable for agricultural waste projects.
  • Features:
    • Heavy-duty construction
    • Top discharge
    • Water jacket with axial flow cooling
    • Double mechanical seal
    • Built-in agitator: Specially designed to create an inherent mixing action at the pump inlet, causing solids to move into suspension and keeping the impeller and flow chamber clear and unclogged.
    • Heavy-duty wear-resistant impeller and agitator.
