Handy, Trash & Diaphragm Pumps

Hard-working drainage pumps for as-required site dewatering or water circulation.

    Deal to nuisance water

    Our range of portable trash, diaphragm and handy-sized submersible pumps work well when dewatering is intermittent or water, sludge or waste volumes are low. They will deal to groundwater, sludge or abrasive liquids with solids in a range of civil, quarrying or mining or municipal applications.
    Ease of use

    Move fluid fast

    With self-prime or no-prime options and electric or petrol drives, our handy-sized pump range is designed for quick set-up and operation.
    Move fluid fast
    Reliability

    Built tough to last

    These pumps work hard. They endure frequent use in contaminated, debris-heavy water, so we choose brands with a reputation for durability.

    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.
