Crest Vertical Immersion Pumps

Peace-of-mind tank maintenance

    Rugged and Reliable Vertical Immersion Pumps for Industrial Applications

    The Crest Pumps range of vertical immersion pumps are resistant to clean or solids-laden corrosive, acidic, or alkali liquid. They feature a cantilever seal-less design, enabling the pumps to run-dry and reducing downtime and maintenance. Use for tank emptying, transfer or recirculation of corrosive liquids. They can be mounted internally or externally, freeing-up valuable tank capacity.
    Seal-less design

    Patented Run-dry Capability

    The VSL, CSS and PPS ranges have no immersed bearings allowing the pumps to run-dry indefinitely without damage. The over-sized cantilever shaft design removes the need for bearings at the bottom of the pumps, increasing stability and preventing shaft whipping - No immersed bearings - No mechanical seal
    Patented Run-dry Capability
    Peace-of-Mind Servicing

    No Obsolete Parts Policy

    Crest pumps are used by some of the world’s largest manufacturers including Unilever, GlaxoSmithKline, BASF Chemicals and General Electric. A two-year warranty is standard, and Crest commits to providing replacement parts for pumps, no matter their age. - Two-year warranty as standard - No Obsolete Parts Policy - Low-maintenance design

    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.
