Cast Iron Submersible Pump Body Premium Casting Services Product

Engineered for Demanding Submersible Applications
Our premium cast iron submersible pump bodies represent the pinnacle of corrosion-resistant, high-strength casting technology. Specifically engineered for continuous submerged operation, these components deliver unmatched reliability in water supply, wastewater management, and industrial pumping applications where failure is not an option.

Superior Material Engineering
We utilize advanced cast iron grades optimized for submersible environments:

• Ductile Iron EN-GJS-500-7: Delivering exceptional tensile strength (500 MPa) and elongation (7%) for shock resistance

• Austempered Ductile Iron (ADI): Providing superior wear resistance and fatigue strength

• Ni-Resist Cast Iron: Offering enhanced corrosion resistance in saline and chemical environments
  All materials feature controlled graphite formation ensuring optimal pressure containment and corrosion performance, with full certification to ISO 1083/JS/500/7 standards.

Advanced Performance Characteristics

• Corrosion Resistance: Withstands pH ranges from 6.5 to 10.0 with specialized coatings available for extreme conditions

• Pressure Integrity: Hydrostatically tested to 1.5 times maximum working pressure (typically 10-25 bar)

• Cavitation Resistance: Superior material density minimizes surface erosion in high-velocity applications

• Thermal Stability: Maintains dimensional integrity across 0-80°C operational range

• Fatigue Strength: Endures continuous operation exceeding 20,000 hours under design conditions
