Sandman^® Magnum pumps are a brand of high-performance centrifugal sand and slurry pumps designed for the most demanding, abrasive, and high-solids applications, including mining, mineral processing, oil drilling, and horizontal directional drilling (HDD).

Key Features of Sandman^® Sand Pumps

• High-Chrome Alloy Construction: To combat extreme abrasion in mining, wet-end components (impeller, casing) are constructed from hard iron or high-chrome alloys, with some options for stainless steel or tungsten carbide coating.

• Open Impeller Design: The pumps feature wide, open-vane impellers that reduce axial thrust and allow for the smooth handling of high-viscosity, sand-laden muds without clogging.

• Modular Configurations: Available in horizontal, vertical, and close-coupled setups to fit tight space constraints.

Andman^® heavy-duty pumps (often identified with high-performance slurry or submersibles in such applications) are suited for mining and mineral processing due to their ability to handle highly abrasive, viscous, and corrosive materials while maintaining durability and low maintenance.

• Handling Abrasive Slurries: Mining, mineral processing, and tailings management involve moving thick slurries (water mixed with sand, gravel, or minerals) that can destroy standard pumps. Andman^® slurry pumps use wear-resistant materials like high-chromium alloys or rubber linings to withstand this abrasion.

• High-Density Solids Transport: Andman^® chemical pumps can handle high concentrations of solids (70% to 80% solids content) common in mineral processing, such as mill discharge, flotation, and thickening.

• Submersible and Severe Service Capability: Mining environments often require pumps to work while fully submerged in deep pits or in contaminated water, featuring sealed motor compartments to protect against water ingress and dirt.

• Corrosion Resistance: To handle the harsh chemicals used in extraction processes and acidic tailings, Andman^® paper stock pumps are often constructed from specialized materials such as stainless steel, Duplex, or rubber-lined components.

Select the suitable slurry pump by long term carefully study, it is anxious for most people. Please don’t worry, just tell your working conditions then our pump engineer will recommend the right solution for you.

Or you can choose the right pumps by the following factors:

• Analyze Slurry Properties: For large, sharp particles, choose heavy-duty hard metal pumps (e.g., high-chrome alloys). For fine, corrosive particles (<500 microns), rubber-lined pumps are often superior.

• Flow Rate (Q): The volume of slurry to be transported per hour.

• Total Head (H): Calculate the static lift (vertical height) and friction losses (pipe length, bends, diameter).

• NPSH (Net Positive Suction Head): Ensure sufficient NPSH is available to avoid cavitation.

• Pump Speed (RPM): Select a pump that operates at a slower speed (ideally 900-1200 RPM) to reduce wear and extend life.
