Industries We Served

Mining & Mineral Processing

Our slurry pump impellers, volutes, cover plates and wear liners are customized for severe mining conditions. In these environments, pumps must handle a mixture of hard particles, corrosive media and continuous heavy-duty operation.

  • Wear-resistant alloys provide strong abrasion resistance.
  • Optimized designs and surface finishes improve corrosion resistance and reduce unexpected downtime.

These solutions help mines extend pump life, cut unplanned shutdowns and keep production stable.

Thermal Power Plants

Our boiler feedwater pump covers are used in thermal power plants, where pumps must work under high temperature and high pressure for long periods.

  • Materials and heat treatment  are chosen to withstand thermal shock, pressure cycling and fatigue.
  • Strict quality control and hydraulic testing help ensure reliable sealing and safe operation over the whole service life.

This gives power plants more confidence in critical boiler feed systems.

Chemical, Metallurgy industry

For circulating water systems in chemical plants, metallurgical facilities and other general industries, we supply grey iron pump covers.

  • Grey iron provides a cost-effective  solution with good dimensional stability.
  • These parts are suitable for cooling water, circulation loops and auxiliary processes, where large volumes and stable operation are required.

Oil & Gas industry

Chemical, Metallurgy industry

Chemical, Metallurgy industry

Our stainless steel and duplex stainless steel pump parts are designed for transporting corrosive liquids in demanding environments, especially in the oil & gas, petrochemical and marine sectors. These media often contain sulfur, chloride ions and other aggressive components.

  • Duplex and stainless grades offer excellent resistance to pitting, crevice and general corrosion.
  • They help reduce leakage and failure risk in pipelines, injection systems and process pumps, and extend maintenance intervals under harsh service conditions.

Other Industries We Serve

Cement & Aggregates

Dredging & Marine Slurry

Quarry, Sand & Gravel

Cement plants and aggregate producers handle extremely abrasive powders and crushed stone. We supply customized liners, chutes, mill components and fittings to reduce wear in grinding, conveying and transfer points, helping extend service life and lower downtime.

Quarry, Sand & Gravel

Dredging & Marine Slurry

Quarry, Sand & Gravel

Quarries and sand–gravel operations face continuous impact and sliding wear from rock and sand. Tailored wear plates, pump parts and chute/conveyor liners protect critical areas, keep material flowing smoothly and reduce unexpected shutdowns in harsh outdoor conditions.

Dredging & Marine Slurry

Dredging & Marine Slurry

Recycling & Scrap Processing

Dredging and marine slurry transport involve highly abrasive sand-water mixtures. Custom pump casings, impellers, liners and pipe fittings are used to resist erosion, control leakage and maintain stable operation on dredgers, dewatering lines and port or river maintenance systems. 

Recycling & Scrap Processing

Recycling & Scrap Processing

Recycling and scrap plants run crushers, shredders and sorting systems on mixed, dirty and often metallic feed. Engineered hammers, breaker plates, liners and chute protection improve wear life, reduce stoppages for repair and support higher, more stable throughput.

Construction Equipment

Construction Equipment

Excavators, loaders, dozers and mobile crushers all depend on heavy-duty wear parts. Customized bucket teeth, cutting edges, side cutters and crusher wear components provide better resistance to impact and abrasion, helping fleets cut maintenance frequency and keep equipment available longer.

Case Studies

Proven Performance in Demanding Conditions

Some working conditions demand complex castings and consistently stable quality. Our case studies highlight how we meet these challenges. By combining deep expertise in corrosion-resistant alloys and steels with state-of-the-art manufacturing and inspection equipment, we deliver components that improve overall plant performance—offering better wear and abrasion resistance, longer service life, and more reliable operation.

Each case shows how we work with customers to understand their site conditions, redesign critical parts and materials, and transform real-world problems into practical, long-term solutions.

Low carbon steel casting- Pump parts

Baseline:

Our solutions

Our solutions

· Cost: Forging offers superior strength but at a higher cost.

· Durability: Cast parts may face fatigue limits under high pressure.

· Complex Geometry: Inlet and outlet covers often have thin walls, intricate shapes, or internal cooling channels—difficult to cast.

· Process Requirements: High-grade alloys, precise cooling control, and post-casting heat treatments are essential.

· Hydraulic Testing: Despite being components only, thorough testing is vital—tooling and sealing design are critical.

Our solutions

We use advanced sand casting with tight control over alloy composition, cooling rates, and heat treatment to achieve zero-defect, high-strength components rated for 38 MPa. Our meticulous process consistently exceeds customer expectations in quality, performance, and reliability.

ASTMA532 series wear resistance castings

Our solutions:

Our solutions:

A leading iron ore plant faced severe wear issues in their slurry pump wet parts (impellers, liners) due to handling large (2-4mm), sharp, and highly abrasive particles at 960 RPM. The original high-chrome white iron components lasted only 300 hours under these harsh conditions.

Our solutions:

Our solutions:

Our solutions:

  • Material Innovation: Redesigned the alloy composition of high-chrome white iron (e.g., optimized Cr/C/Mo ratios) to enhance wear resistance while maintaining critical impact toughness. The micro-structure contains rod-shape carbide and martensite matrix, refer to the picture below, the abrasion performance of the bar shape carbide is superior than cellular shape carbide in some extent. 
  • Lab Validation: Conducted rigorous abrasion testing and impact tests 
  • Field Performance: Achieved a 480-hour service life in operational trials, extending component longevity and reducing downtime.
