Self-Priming Centrifugal Pumps

Handle Polluted, Waste and Abrasive Fluids with Suspended Solids.

    Performance at demanding heights

    Varisco’s J-Series self-priming centrifugal pumps are ideal for applications requiring rapid priming from high suction heights while handling polluted, waste, and abrasive fluids with suspended solids. Their inspectable pump casing doubles as a water reservoir, enabling quick priming without auxiliary systems, simplifying management and reducing maintenance
    Varisco J-Series

    Ease of use

    • Above ground installation – for easier control, maintenance, and management compared to submerged or vertical shaft pumps.
    • Inspection and drainage covers – allow for easy filling, washing, and unclogging
    • Wear Parts Replacement – Easily replaceable components restore original performance.
    Ease of use
    Varisco J-Series

    Durable, Versatile Pumps

    • Durable Construction – Thick-walled castings in various metallurgies resist wear and corrosion.
    • Customizable Seals – Mechanical seals with material options resist abrasion and chemical attack.
    • Solid Handling – Semi-open impeller (various metallurgies) passes solids from 8 to 76 mm.
    • Versatile Fluid Handling – Standard design supports up to 50cSt viscosity, with options for denser slurries.

    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.
