OEM Deep Well Iron Submersible Water Pump Parts Custom Casting Services

Material Excellence and Performance Characteristics

We utilize high-grade grey iron (Grades HT200-HT350) and ductile iron (QT450-10, QT500-7) specifically engineered for submersible pump applications. These materials offer excellent mechanical properties and corrosion resistance in underwater environments. Grey iron castings provide tensile strength of 200-350 MPa with superior vibration damping capacity, while ductile iron components deliver enhanced strength of 450-500 MPa with 7-10% elongation, ensuring reliable performance under high-pressure conditions. The materials demonstrate outstanding corrosion resistance in various water conditions and maintain structural integrity during continuous submersion operations.

Advanced Manufacturing Process

Our production methodology employs sophisticated casting techniques optimized for pump components:

Sand Casting Technology
We employ resin sand molding systems that enable production of complex internal flow passages and consistent wall thickness maintaining structural integrity. The process ensures superior surface finish reducing hydraulic losses and turbulence within pump chambers.

Precision Pattern Engineering
Our CAD/CAM designed patterns incorporate optimal shrinkage allowances and strategic gating systems ensuring proper metal flow. The patterns are engineered with proper draft angles for extraction and venting placement to minimize casting defects in critical pump components.

Quality Assurance and Performance Validation

Each pump component undergoes rigorous quality control:

• Pressure testing to 150% of working pressure requirements

• Hydrostatic testing for leak-proof performance validation

• Ultrasonic inspection for internal defect detection

• Material composition analysis through spectrochemical testing

• Dimensional verification using coordinate measuring machines
