​High-Quality Pump Castings and Housings

1. What Are Pump Castings? Core Applications Across Industries

Pump castings are critical components in fluid transport systems, serving as structural frameworks for centrifugal pumps, sewage pumps, and industrial pumps

. They ensure operational stability under high pressures (up to 6MPa) and corrosive environments, making them indispensable in:

• Water Supply: Centrifugal pump housings for urban water networks

• Sewage Treatment: Ductile iron components resistant to chloride-rich wastewater

• Oil & Gas: Multi-stage casings for hydrocarbon transport

2. How Do Materials and Processes Ensure Performance?

Materials:

• Ductile Iron (EN-GJS-500-7): Combines 450MPa tensile strength with graphite spheroidization for sewage pump bodies

• Low-Alloy Steel (Cr-Mo-Mn): Hardness up to 55HRC for abrasive slurry environments

Advanced Processes:

Quality Assurance:

• MAGMA Solidification Simulation: Reduces internal defects by 90%

• 100% PT/RT Inspection: Complies with ISO 2531 and BS EN 545 standards

3. Why Choose Ductile Iron Pump Housings?

• Corrosion Resistance: Zinc-aluminum coatings (≥130g/m²) protect against acidic media

• Pressure Integrity: Validated by ISO 2531-certified 49N/30min leak-proof tests

• Cost Efficiency: Sand casting reduces production costs by 44%

4. How to Select the Optimal Casting Process?

• Sand Casting: Ideal for large-scale, economical production of pump bodies

• Resin Sand Casting: Balances precision and cost for complex flow channels

• Investment Casting: Best for high-precision components like impellers

Recommendation: Match project requirements with process strengths—e.g., resin sand for multi-stage pumps

5. How to Customize and Procure Globally?

Tailored Solutions:

• Adjustable wall thickness (28-150mm) and alloy compositions

• Surface treatments: Epoxy coatings or cement mortar linings

Global Support:

• Rapid Prototyping: 3D-printed molds delivered in 16 days

• Certifications: ISO 9001, CE, API 610
