Submersible Drainage Pumps

Submersible drainage pumps manage water levels and prevent flooding to ensure safe, efficient operations.

    Continuous operation, minimal maintenance

    Submersible drainage pumps remove or transfer excess water from work sites - either off-site or to where it’s needed, helping maintain dry, safe, and operational conditions in civil construction, mining, and quarrying across New Zealand.

    By shifting water quickly, they reduce costly downtime and keep crews on the job. Because they run submerged, drainage pumps do not need priming and are less prone to cavitation. They are suited to water with fine abrasives and light suspended solids.

    We supply a range of drainage submersible pumps to suit your conditions, from rainwater in trenches and excavations to pump stations and corrosive mine environments. Our team helps you specify the setup best suited to your drainage needs, including duty point, materials, and accessories, with service and support across New Zealand.

    What is the difference between a slurry pump and a sludge pump?

    A slurry pump is designed to move mixtures of liquid and solid particles where the liquid component helps the material flow. It is built with abrasion and corrosion resistant materials and a robust design to handle the wear from suspended solids.

    A sludge pump is designed to handle much thicker and stickier material known as sludge which has a higher solid content. These pumps often use positive displacement or slow moving mechanisms to avoid clogging and manage dense viscous fluids.
    How do sludge pumps work?
    Sludge pumps move heavy viscous mixtures using either centrifugal or positive displacement methods. Centrifugal sludge pumps use a rotating impeller to generate pressure and move the sludge. Positive displacement sludge pumps, such as progressive cavity, diaphragm, or lobe pumps, trap a fixed volume of sludge and force it through the pump. This method is especially useful for very thick or high-solid-content applications.
    What is the main source of sludge?
    Sludge typically comes from wastewater treatment processes where water is separated from solids through sedimentation or filtration. It is a semi-solid byproduct that can contain organic matter, heavy metals, and other impurities. Sludge can also come from industrial operations such as mining or manufacturing plants, where process residues and waste streams generate similar thick, viscous materials.
