Viscous Fluids Pumps

Maintaining flow efficiency no matter the media.

    We'll keep things flowing

    Viscous fluid pumps are used across various industries where thick or semi-solid materials need to be transferred, mixed, or processed efficiently.

    Selecting the right pump is crucial for maintaining flow efficiency, preventing clogging, and reducing wear. Prime Fluid Management supplies a range of pump types and models from, recognised manufacturers, to ensure we meet your unique industrial requirements.
    Gear Pumps

    Shifting oils, polymers and adhesives

    Gear pumps work when two interlocking gears rotate to move fluid. They suit medium- to high-viscosity fluids, including oils, polymers, and adhesives.

    • High-pressure capability with precise dosing.
    • Compact and efficient for lubricating or non-abrasive viscous fluids.
    • Self-priming, positive displacement
    • Our brands: GVR Pumps 
    Shifting oils, polymers and adhesives
    Progressive Cavity Pumps

    Handling extreme viscosity

    Progressive Cavity, or PC, pumps have a helical rotor that moves through a series of small chambers, maintaining consistent, low-pulsation flow.

    • Handles sludges, pastes, and solids-laden fluids
    • Low shear, ideal for fragile or shear-sensitive materials

    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.
