Standard Light Duty Slurry Pump XL(R)

XL(R) light-duty slurry pumps run at higher rotation speeds with smaller, lighter frames versus heavy-duty pump models. They are engineered for fine solid particles and thin slurry, suitable for media with weight concentration under 30%. They also work well for dense slurries with low abrasiveness.

Sharing a similar framework with SH heavy-duty slurry pumps, XL(R)pumps are horizontal cantilever centrifugal slurry pumps with double-shell, single-stage, single axial suction layout. The outer housing is cast ductile iron, fitted with high-chrome alloy wear-resistant flow components. Three sealing styles are available: packing gland, expeller and mechanical seal. The bearing unit adopts grease lubricated roller bearings.For impeller configurations: semi-open impellers equip models with discharge size ≤200mm; closed impellers come on pumps with outlets ≥250mm.

With outstanding efficiency, long service life and competitive cost performance, XL(R)pumps are widely applied in mining, ore dressing, metallurgy, power generation and other light slurry transportation industries.

Core Advantages

1. Small & Light StructureCompared with heavy-duty slurry pumps, LS models take up less space and weigh far less, simplifying installation and daily maintenance work.

2. Great for Fine Particle SlurryPerfect for pumping fine solids or low-density slurry media, delivering higher efficiency while cutting your running costs.

3. Anti-Corrosion & Wear ResistantDuctile iron outer shell matched with high-chrome alloy wet-end liners enables stable delivery of slightly corrosive slurry.

4. Multiple Shaft Seal ChoicesThree sealing types (packing, expeller, mechanical seal) are optional to match different working medium conditions.

5. Stable Rotation AssemblyGrease-filled heavy-duty roller bearings plus large-diameter short cantilever shaft design extend service life and guarantee steady operation.

6. Flexible Discharge AngleThe pump outlet can be set at every 45°, offering 8 mounting directions to fit various on-site pipeline layouts.

Typical Application Scenarios

Power & Chemical Industries:Serves as sludge transfer pumps for water treatment processes to process waste media and maintain qualified clean water discharge.

Steel Manufacturing Plant:Acts as flushing pumps in rolling lines to wash away residues and cool rolled steel products.

Mine Tailings Circulation:Works as overflow recycling pumps to reclaim reusable water resources, lower raw material loss and reduce mining environmental pollution.

Municipal Wastewater Projects:Functions as sludge draining equipment in sewage treatment stations to realize full waste disposal and standard water purification.

General Industrial Fields:Suitable for conveying all types of low-abrasion and slightly corrosive slurry mixtures.

Structural features

1. This pump is applicable to high duty and severe operating conditions for having large diameter and short cantilever to ensure the rigidity of the shaft.

2. The hardened stainless sleeve and the shaft are equipped through clearance fit, coupled with O-ring on the two ends, thus the shaft is of wear-resisting and anti-corrosion.

3. Either the front or back cover board of the impeller is equipped with auxiliary blade, which can reduce the return flow and the seal pressure. Other methods like a wider-runner and blade concave are adopted to enhance overcurrent ability and anti-abrasion ability for extending the service life.

4. The ability of withstanding high pressure of the pump casing and cover is ensured by using ductile iron material and strengthening rib.

5. The overcurrent components adopt various high Cr anti-abrasive alloys or different rubber and are of anti-abrasive, anti-corrosion, impact resistance, scouring resistance and other features. Moreover, the metal overcurrent components and the rubber ones can be used interchangeably or in a mixer way to satisfy the requirement of different operating conditions.

6. Seal types like packing seal, auxiliary impeller seal, and mechanical seal are available for shaft seal to satisfy different seal requirement.

7. You can choose to install the output position of the pump by eight different angles (with an interval of 45 degrees).

8. Oil lubrication and grease lubrication are provided to the bearing assemblies. The oil lubrication components is able to lower the operation temperature effectively to reduce the trouble caused by too high bearing temperature. The grease lubrication components have features of simple structure, reliable operation, and easy installing, commissioning and maintenance.
