How to Select a Pump Model

FB / AFB Pump Selection Criteria

  1. Confirm liquid chemical composition and stainless steel grade compatibility.
  2. Determine required duty point (flow rate & head) within efficient operating range.
  3. Evaluate sealing configuration for volatile or hazardous media.
  4. Verify system pressure and temperature limits.
  5. Consider corrosion category to select FB or AFB structural variant.
✔ Final model selection should be based on media corrosivity, duty point, and required stainless steel grade.

 Engineering Notes

  • Not suitable for slurry or high-abrasive media.
  • Avoid dry-running to protect mechanical seal.
  • Chloride-rich environments may require higher-grade stainless steel.
  • Seal flushing may be required for hot or volatile liquids.

Compliance & Quality Assurance

  • Factory hydrostatic pressure test
  • Hydraulic performance verification
  • Material traceability documentation
  • Rotor dynamic balance test
  • Optional third-party inspection available

Safety Notice

  • Do not operate under dry-running condition
  • Ensure proper priming before startup
  • Avoid exceeding rated pressure
  • Disconnect power before maintenance

OEM & Customization

This pump series supports engineered configuration and duty-based matching. Technical adjustments can be made according to system requirements and installation conditions.

Available options include:

• Motor voltage & frequency
• Mechanical seal type and configuration
• Stainless steel material grade selection
• Surface finishing and corrosion protection
