Slurry Pump: What is it, and how does it work

Pumps designed for pumping slurries will be heavier duty than those designed for less viscous liquids since slurries are heavy and difficult to pump.

Slurry pumps are typically larger in size than standard pumps, with more horsepower, and built with more rugged bearings and shafts. The most common type of slurry pump is the centrifugal pump. These pumps use a rotating impeller to move the slurry, similar to how a water-like liquid would move through a standard centrifugal pump.

For more information, please visit SGB.

Centrifugal pumps optimized for slurry pumping will generally feature the following in comparison to standard centrifugal pumps:

  • Larger impellers made with more material. This is to compensate for wear caused by abrasive slurries.
  • Fewer, thicker vanes on the impeller. This allows the passage of solids more readily &#; typically 2-5 vanes, compared to 5-9 vanes on a standard centrifugal pump.

For pumping abrasive slurries, these types of pumps may also be made from specialized high wear alloys such as AL-6XN® or Hastelloy® C-22®. Hardening stainless steel is also a common option for abrasive slurries, with Expanite and Armoly being two hardening processes.

    For certain types of slurry pumping conditions, positive displacement pumps may be a more appropriate choice than a centrifugal-style pump.

    These conditions include:

    • A low slurry flow rate
    • A high head (i.e., the height to which the pump can move liquid)
    • A desire for greater efficiency than that afforded by centrifugal pumps
    • Improved flow control

    Common types of positive displacement pumps used in slurry pumping applications include:


    Rotary Lobe pumps

    These pumps use two meshing lobes rotating within a pump's housing to move fluids from the pump's inlet to its outlet.


      Twin-screw pumps

      These pumps employ rotating screws to move liquids and solids from one end of the pump to another. The screws' turning action creates a spinning motion that pumps material.


        Diaphragm pumps

        These pumps use a flexible membrane that expands the volume of the pumping chamber, bringing in fluid from an inlet valve and then discharging it through an outlet valve.


        Selecting and operating a slurry pump

        Choosing the right pump for your slurry application can be a complex task due to the balance of many factors including flow, pressure, viscosity, abrasiveness, particle size, and particle type. An applications engineer, who knows how to take all of these factors into account, can be a great help in navigating the many pump options available.

        5 advantages of customized slurry pumps

        Standard pumps are not for everybody, customized slurry pumps are the best choice for the industrial sector. Every company has his needs in pumping slurry materials and, even if in some circumstances you can choose a standard pump, most of the times you better choose a customized pump.

        Heavy duty pumps and slurry pumps have several applications, and it is impossible to have just one standard pump for every use. Every customer has his own need, his area of work and his type and volume of stuff to pump out. For that, Pemo Pumps teamwork is mostly dedicated to build and assemble the right components to customize the perfect pump for the specific client.

        Customized slurry pumps offer significant advantages over standard pumps in every industrial applications. They are tailored to meet the specific requirements of a given application, which can include unique flow rates, pressures, viscosities, temperatures, and corrosive properties of the fluid being pumped.

        This customization can lead to increased efficiency and reliability, especially when pumping thick, abrasive, or corrosive liquids. Moreover, customized pumps are designed to reduce downtime, as they are less prone to clogs and blockages, and they often require less maintenance, saving on costs and reducing the need for frequent repairs or part replacements.

        Additionally, they provide greater control over the flow rate, which is crucial in processes where precision is key. Overall, the use of a customized slurry pump can result in improved performance, longevity, and cost savings overall.

        Single components of a customized slurry pump are the impeller, the casing, the motor (engine) and the shaft. Impellers optimize the passage of abrasive solids while considering erosive wear that can affect performance. The primary function of a slurry pump casing is to guide the slurry from the pump inlet to the impeller and then control its flow before discharge.We also have the motor and, finally, we have the shaft in a slurry, the component that connects the impeller to the motor or engine.

        For Pemo Pumps the most important components of a customized slurry pump are the impeller and the bodies. We put a lot of attention in the materials, on which we concentrate all the studies and projects and decades of know-how in terms of engineering and attention to the details.
