Lime Slurry Pumps for Water Treatment and Industrial Applications

Durable and reliable lime slurry pumps

Durability and precision are essential when working with abrasive, high-viscosity materials like lime slurry. Commonly used in water treatment and industrial processes, it demands equipment built to handle dense, corrosive mixtures without excessive wear.

Global Pumps supplies a range of heavy-duty lime slurry pumps designed for transferring, dosing, and metering applications. Engineered for long service life and low maintenance, these pumps offer reliable performance in demanding environments where accuracy and uptime are critical.

Applications and industries

Lime slurry pumping plays an important role in a variety of sectors, particularly those focused on neutralisation, pH control, and materials processing. Common applications include:

• Water and wastewater treatment – dosing liquid lime to neutralise acidic water and stabilise pH.
• Sludge treatment and dewatering – conditioning sludge with lime to improve solids separation.
• Mining and minerals processing – using lime transfer pumps for pH regulation and metallurgical treatment.
• Power generation – lime dosing in flue gas desulphurisation systems to remove sulphur dioxide.
• Chemical and industrial plants – lime slurry circulation for neutralisation, scrubbing, and process control.

Across these industries, precision and reliability are key. Choosing the right lime slurry dosing pump helps prevent blockages, reduces wear, and ensures consistent chemical dosing.

Lime slurry pumping in water treatment

In water treatment, hydrated lime (also known as lime slurry or milk of lime) is used to correct pH levels and stabilise wastewater. The process requires pumps capable of handling abrasive, high-density fluids without clogging or leakage.

Precision dosing is essential to achieve consistent neutralisation and efficient pH control. The right pumping system ensures a steady flow of lime solution through tanks and pipelines while keeping solids in suspension to prevent settling and maintain reliable system performance.

Choosing the right pump for lime dosing and transfer

Due to its abrasive and corrosive nature, lime slurry demands robust and low-maintenance pumping technology. Global Pumps recommends:

• Peristaltic pumps - these pumps provide exceptional abrasion resistance and handle fluids with high solids content. The peristaltic action keeps lime particles suspended, preventing settling and ensuring a uniform mixture. Their leak-free, sealless design makes them a top choice for lime slurry transfer pumps and dosing systems.
• Slurry pumps - For larger-scale material transfer, centrifugal configurations can provide the flow rates required for continuous operations. Constructed with wear-resistant components, they are ideal for slurry recirculation or bulk transport.
