Our design stage is the foundation of high-performance slurry pumps, integrating advanced fluid dynamics, material science, and application-specific working conditions. Our engineering team uses 3D modeling, CFD simulation, and finite element analysis (FEA) to optimize hydraulic structures, flow passages, and structural strength. We provide both standardized designs and fully customized solutions for mining, metallurgy, coal washing, power plant ash handling, dredging, and other harsh abrasive working conditions.

By simulating real slurry flow, wear distribution, and pressure load, we improve efficiency, wear resistance, and operational stability. Each design undergoes strict performance verification to ensure the pump matches flow rate, head, solid concentration, and medium corrosiveness. We also focus on maintainability and interchangeability of parts, reducing lifecycle costs for users. Every drawing and parameter is strictly reviewed to ensure manufacturability, reliability, and compliance with international standards, laying a solid technical foundation for subsequent production.

Casting and forging are core processes for forming slurry pump critical components such as impellers, volute casings, liners, and shafts. We adopt advanced casting technologies including resin sand casting, investment casting, and centrifugal casting to produce high-density, low-defect metal blanks. For materials, we use high-chromium white cast iron, alloy cast iron, wear-resistant alloy steel, and other specialized materials to resist strong abrasion and corrosion from solid particles.

Forging is applied to high-strength parts like shafts and flanges, using precise forging equipment to refine grain structure, improve mechanical strength, toughness, and fatigue resistance. We implement strict incoming material inspection, smelting control, and blank forming monitoring. Each casting and forging part undergoes visual inspection, dimensional measurement, and internal defect detection to eliminate porosity, shrinkage, cracks, and inclusions. High-quality blanks ensure stable performance and long service life in extreme working conditions.

Heat treatment is essential to enhance mechanical properties, wear resistance, and stability of slurry pump parts. Based on material characteristics and application requirements, we use processes including quenching, tempering, normalizing, annealing, and aging treatment to adjust internal structure and hardness.

For high-chromium wear-resistant parts, we use specialized hardening and tempering processes to achieve ideal hardness and toughness matching, improving resistance to abrasive wear and impact. For shaft-type forged parts, we use quenching and tempering to ensure high strength, rigidity, and fatigue durability. Real-time monitoring and precise control of temperature, holding time, and cooling rate ensure stable and consistent performance.

After heat treatment, parts undergo hardness testing, metallographic analysis, and stress relief inspection. This process greatly improves service life, reduces deformation and failure risks, and ensures components maintain dimensional stability and performance under long-term harsh conditions.

Machining transforms cast and forged blanks into finished components with strict dimensional accuracy. We are equipped with CNC lathes, machining centers, boring machines, milling machines, and grinding machines, operated by skilled technicians. High-precision equipment ensures dimensional accuracy, form and position tolerance, and surface roughness meet design standards.

Key parts such as impellers, shafts, volute casings, and bearing housings undergo multi-process processing. Strict tool selection, cutting parameter optimization, and real-time monitoring guarantee high efficiency and precision. Dimensional inspection using calipers, micrometers, height gauges, and coordinate measuring machines (CMM) ensures every part meets drawing requirements.

High machining accuracy directly affects assembly quality, operational stability, and hydraulic performance. It reduces vibration, noise, and wear, improves assembly efficiency, and ensures reliable operation and long service life.

The impeller dynamic balancing test eliminates unbalanced mass to ensure smooth, low-vibration, low-noise operation. Unbalanced impellers cause severe vibration, bearing damage, seal failure, and reduced pump life.

We use professional dynamic balancing machines to test each impeller. After testing, we correct unbalance by material removal or weighting to meet strict balancing grades. The entire process follows international standards, with detailed records and traceability.

Qualified dynamic balancing ensures the impeller runs stably at rated speed, reduces vibration and noise, prolongs bearing and seal life, improves transmission efficiency, and enhances overall reliability and service life.

Assembly integrates all components into a complete slurry pump, directly influencing performance and reliability. Our assembly follows strict technological procedures and quality standards. Technicians assemble shafts, bearings, impellers, volutes, liners, seals, and brackets in a clean, specialized workshop.

We control bearing preload, seal installation, fit clearances, and fastener torque. Key parts are cleaned, inspected, and lubricated to avoid damage and ensure smooth operation. Each step is recorded for full-process traceability.

Standardized, precision assembly ensures concentricity, sealing, and matching performance. It reduces internal friction, leakage, and abnormal noise, guaranteeing smooth startup, stable operation, and excellent hydraulic performance.

Before delivery, every slurry pump undergoes comprehensive performance testing under simulated actual working conditions. The test bench measures flow rate, head, efficiency, input power, current, voltage, vibration, noise, and temperature.

We test startup performance, no-load and load operation, continuous operation stability, sealing, and pressure resistance. Performance curves are compared with design values to ensure parameters meet requirements. Vibration and temperature monitoring identify potential defects.

Only pumps passing all tests are approved. This strict verification ensures stable, efficient, safe, and reliable operation at the user’s site.

Painting and packaging protect appearance and performance during storage and transportation. Surface preparation includes sandblasting and primer-coating to improve adhesion and anti-corrosion.

We use wear-resistant, anti-corrosion, and weather-resistant coatings according to customer and environmental requirements. Uniform coating thickness, smooth surface, and consistent color enhance appearance and protect against rust, corrosion, and damage.

Packaging uses sturdy wooden cases, cushioning, and fastening to prevent collision, moisture, and oxidation. Each package is labeled with model, specification, quantity, and barcode for identification and logistics. Anti-rust and moisture-proof measures are applied for long-distance transport.

This stage ensures the pump arrives in perfect condition, ready for installation and commissioning.
