  • Stainless Steel (304, 316, Duplex SS): For corrosive environments, including chemical and marine applications.
  • High-Chrome Alloys (Cr26, Cr27): Essential for abrasive slurry applications, especially for components like wholesale slurry pump parts impeller and casings, offering superior wear resistance.
  • Nitrile Rubber, Polyurethane, or Elastomers: For liners and specific impellers, such as a wholesale slurry pump rubber impeller, designed for soft abrasive handling.

2. Component Manufacturing

• Casting: Precision casting for pump casings, impellers (e.g., slurry pump open impeller, wholesale slurry pump closed impeller), and volutes. Utilizes sand casting or investment casting, followed by heat treatment to achieve desired metallurgical properties and stress relief.
• Forging: For high-stress components like shafts, ensuring superior strength and fatigue resistance.
• CNC Machining: High-precision machining of critical components, including impeller balancing, shaft concentricity, and seal housing tolerances. This stage is crucial for hydraulic efficiency and preventing premature wear, especially concerning the exact dimensions of a wholesale slurry pump impeller vane.
• Motor Winding: Automated winding and insulation of copper coils for the submersible motor, followed by vacuum pressure impregnation (VPI) for moisture and heat resistance.

3. Assembly and Sealing

• Motor Assembly: Integration of rotor, stator, bearings, and thermal protection.
• Mechanical Seals: Dual or triple mechanical seal systems (e.g., Tungsten Carbide vs. Tungsten Carbide) are critical for preventing water ingress into the motor chamber.
• Pump Head Assembly: Connecting the impeller, diffuser, and volute casing.
• Overall Integration: Final assembly of the motor unit, pump head, and external components.

4. Testing and Quality Assurance

• Hydrostatic Testing: To ensure casing integrity and seal effectiveness under pressure, often exceeding operational limits.
• Performance Testing: Conforming to standards like ISO 9906 (Grade 1B or 2B) and ANSI/HI 9.6.1, evaluating head, flow, power consumption, and efficiency at various operating points. This includes NPSH testing.
• Vibration Analysis: To detect imbalances or bearing issues, ensuring smooth operation and extended service life.
• Electrical Testing: Insulation resistance, hi-pot, and phase balancing tests for motor integrity.
• Material Composition Analysis: Spectrographic analysis to verify alloy compositions.

These rigorous processes ensure that our submersible pumps meet international standards and are optimized for a long service life, typically ranging from 5 to 15 years depending on the application and maintenance schedule. Our target industries include petrochemical, metallurgy, mining, municipal water supply & drainage, and wastewater treatment, where the advantages of energy saving and corrosion resistance are paramount.
