Submersible Slurry Pump with agitator large particle - Tussu Pumps

Submersible Slurry Pump with Agitator for Large Particles: A Comprehensive Overview

A Submersible Slurry Pump with Agitator is a specialized heavy-duty pump designed to operate fully submerged, handling highly abrasive slurries containing large solid particles (typically >50mm/2 inches, with some models exceeding 100mm/4 inches). Its integrated agitator prevents solids from settling, ensuring consistent pumping efficiency.

Key Components & Functionality:

Submersible Motor:

Sealed, oil-filled, or water-cooled design. Waterproof insulation (IP68 rating). Engineered to withstand submersion pressure and slurry ingress.

Robust Pump Casing:

Made of high-chrome white iron (27% Cr), hardened cast steel, or wear-resistant alloys. Thicker walls for abrasion resistance. Large volute passages to pass big solids.

Large-Particle Impeller:

Vortex (recessed), semi-open, or wide-channel design. Minimizes direct contact with large solids to reduce clogging/wear. Fewer vanes (often 2-3) for unimpeded particle passage.

Integrated Agitator:

Mounted beneath the pump intake. Rotating blades/impellers scour the pump sump. Suspends settled coarse solids and breaks up packed material. Ensures a homogenous mixture enters the pump.

Heavy-Duty Mechanical Seal:

Multiple seals (often cartridge-type). Tungsten carbide/silicon carbide faces. Seal flush systems (external or clean water) to protect against grit.

Critical Design Features for Large Particles:

Extra-Large Solids Passage: Oversized suction inlets and internal flow paths accommodate rocks, debris, and coarse solids. Agitator Power: High-torque agitator drive ensures effective fluidization of dense/dense-packed solids. Wear Protection: Replaceable liners, hardened wear plates, and abrasion-resistant coatings extend lifespan. Heavy-Duty Bearings: Oversized bearings handle radial/axial loads from agitator and pump. Robust Construction: Thick shafts, reinforced housings, and heavy-duty fasteners withstand impacts.

Primary Advantages:

Handles Extreme Slurries: Efficiently pumps mixtures with very high solids content (up to 70% by weight) and large, heavy particles. Eliminates Settling: Agitator prevents solids from compacting, ensuring continuous flow. Reduced Clogging: Large clearances and agitator action minimize blockages. Portability & Versatility: No priming needed; easily deployed in deep sumps, pits, or moving water bodies. Lower Installation Cost: Eliminates complex dry-pit structures, long shafts, and priming systems. Operator Safety: Reduces manual agitation/handling of hazardous slurries.

Typical Applications:

Mining: Dewatering open pits, tailings handling, processing slurries with large ore fragments. Dredging: Sand, gravel, and silt removal with rocks/shells. Construction: Pumping from foundation trenches, tunnels, and caissons containing debris. Mineral Processing: Handling coarse feed stock, mill discharge, and cyclone underflow. Industrial Waste: Pumping bottom ash, foundry slag, or effluents with solid chunks. Quarrying & Aggregate: Settling pond cleanout, wash plant solids.

Key Considerations:

Wear Life: Abrasion is inevitable; component selection (materials) and maintenance are critical. Agitator Clearance: Must be adjusted based on solids size/density for optimal performance. Power Requirements: High torque needed for agitator and solids handling increases energy demand. Seal Integrity: The most critical component; failure leads to motor damage. Particle Size Limits: Verify pump specs match your maximum expected particle size.
