    Progressive Cavity Hopper Feed Pumps

    Wangen produces an extensive range of hopper feed pumps for slurries and pastes with high solids content (KL-R Series) and dewatered sludge (KL-RU, KL-RQ, KL-RS and KL-R Triplex models).

    • Max flow: 560m3/hr
    • Max pressure: 48 bar
    • Max solids: 45%
    • For extremely dry or lumpy material
    Progressive Cavity Self-Priming Pumps

    Wangen's KL-S, KB-S and KB22S self-priming progressive cavity pumps convey high viscous media up to 200,000 mPA-s, with or without solids. The KB22S is designed specifically for dosing.

    • Max Flow: 560 m3/hr
    • Max Pressure: 48 bar
    • Materials: S/steel, cast iron
    Self-Priming Centrifugal Pumps

    Varisco J-Series pumps suit applications that require fast priming from demanding suction heights, and the ability to manage polluted waste and abrasive fluids with suspended solids.

    • Max flow: 1200m3/hr
    • Max head: 110m
    • Max solids: 76mm
    • Self-priming: up to 7.5m
    Stirrers

    SolidsPro stirrers ensure uniform mixing in waste liquids with solids present – to prevent sedimentation and enhance biological or chemical reactions. Commonly used in storage sumps, tanks and ponds to prevent solids from settling out.

    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.
