Chifine
Ductile iron pump parts manufactured via shell mold precoated sand casting are high-performance components engineered for reliability in pumping systems. As a flagship product of Qingdao Chifine Machinery—a specialist in metal casting with over 10 years of experience—these parts utilize premium ductile iron and advanced casting technologies to deliver superior strength, ductility, and corrosion resistance. The precoated sand casting process ensures precise dimensional accuracy, while heat treatments (quenching, tempering, annealing) enhance mechanical properties, making them ideal for municipal drainage, power stations, industrial equipment, and marine applications. Compliant with ASTM, DIN, and ISO standards, these sand casting pump parts integrate seamlessly with various pump models, providing long service life even in high-pressure and abrasive environments.
High-quality ductile iron material: Offers excellent impact resistance, tensile strength, and fatigue durability compared to traditional grey iron.
Advanced shell mold precoated sand casting: Ensures smooth surface finish, tight dimensional control, and reduced machining requirements.
Comprehensive heat treatments: Quenching, tempering, annealing, normalizing, nitridation, and carburization optimize material performance for specific applications.
Versatile surface protections: Zinc plating, hot-dip galvanizing, painting, powder coating, and polishing prevent corrosion and extend service life.
Rigorous quality testing: Equipped with direct-reading spectrographs, ultrasonic flaw detectors, and hardness testers for full material and performance verification.
Wide weight range: From 0.1kg to 3000kgs, accommodating small fittings and large pump components.
Efficient production capacity: Large-scale manufacturing facilities ensure fast lead times after order confirmation.
Custom design support: Utilizes Pro/E, AutoCAD, and Solidworks for precise drawing execution, adapting to unique pump specifications.
Centrifugal pumps, sewage pumps, and water supply pumps: Used for municipal, industrial, and agricultural water management, handling various fluid types.
Power stations: Boiler feed pumps, cooling water pumps, and condensate pumps operating under high temperature and pressure.
Marine equipment: Shipboard pumps, ballast pumps, and bilge pumps resistant to saltwater corrosion.
Construction industry: Concrete pumps, irrigation pumps, and dewatering pumps for construction sites with complex working conditions.
Mining machinery: Slurry pumps, mine drainage pumps, and ore processing pumps handling abrasive materials.
Chemical pumps, oil pumps, and process pumps: Suitable for manufacturing and refining operations, with resistance to chemical corrosion.
