Solids Handling Pumps & Stirrers

Make light work of thick, fibrous, high-solids pumping.

    Reduce clogging and wear

    Solids handling pumps are designed to move fibrous, thick, and grit-laden materials without clogging or excessive wear. Different pump types achieve this through specialised designs:

    • Vortex Pumps: Use a recessed impeller to create a vortex, allowing solids to pass with minimal contact, reducing wear.
    • Progressive Cavity Pumps: Utilise a helical rotor-stator system to move thick, shear-sensitive materials like sludge and food waste.
    • Self-Priming Centrifugal Pumps: Handle solids while allowing easy re-priming, making them ideal for intermittent operation in wastewater and industrial drainage.
    • Twin Screw Pumps: Offer smooth, pulsation-free flow, ideal for viscous and shear-sensitive fluids in food processing and chemical industries.
    Prime Fluid Management can recommend the solids-handling pump or stirrer to best meet your needs. Take a look at our range below.

    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.
