Sludge & Slurry Submersible Pumps

Your pit dewatering could do better.

Sludge and slurry submersible pumps are specialised pumps built to withstand highly abrasive fluids. They are constructed from hard metals and abrasion-resistant linings, with added features to prevent obstruction, overheating, and excessive wear.

These pumps are ideal for moving thick, solid-laden liquids such as wastewater and sludge from ponds, tanks, or treatment facilities. Whether you're managing water transfer on a construction site, cleaning out a sediment-filled pond, or handling industrial wastewater, submersible sludge pumps offer a reliable and portable solution.

Avalible for both hire and sale across New Zealand, these pumps are commonly used for dewatering, desludging, and transferring heavy liquids where durability and efficiency are critical.
