Product Overview

IHF Fluoroplastic Alloy Chemical Pump (Single Stage)

IHF Fluoroplastic Alloy Chemical Pump is a single-stage horizontal centrifugal pump with fluoroplastic-lined wetted parts, designed for highly corrosive chemical liquid transfer in industrial process systems.

It resolves severe corrosion failure, short service life of metal pumps, and leakage risks in aggressive acid-alkali media.

It is suitable for acid and alkali transfer, pickling systems, electroplating circulation, chemical dosing, and aggressive liquid process transport.

✔ Engineered for highly corrosive chemical duty requiring fluoroplastic-lined flow passage and stable horizontal process integration.

Model Designation

IHF Fluoroplastic Alloy Chemical Pump Single Stage

Applications

Typical Operating Scenarios

  • Concentrated sulfuric acid transfer lines
  • Hydrochloric acid pickling circulation systems
  • Electroplating chemical circulation
  • Alkali solution dosing and transfer
  • Chlor-alkali process liquid handling
  • Corrosive wastewater transfer in chemical plants

Engineering Advantages 关键工程优势

Structural Design Logic & Engineering Results

• Fluoroplastic alloy lining provides superior corrosion resistance against strong acids and alkalis → Extended service life in aggressive media

• Back pull-out structure enables maintenance without dismantling pipeline → Reduced downtime

• Heavy-duty shaft support with corrosion-resistant sleeve → Improved mechanical stability

• Standardized mechanical seal chamber design → Compatible with multiple sealing configurations

✔ Designed for long-term operation in high-corrosion chemical environments where metal pumps are not suitable.

How to Select a Pump Model

IHF Chemical Pump Selection Criteria

  1. Confirm chemical compatibility between fluoroplastic lining and media composition.
  2. Determine required duty point (flow rate & head) within high-efficiency range.
  3. Evaluate sealing requirements based on toxicity and volatility.
  4. Confirm temperature and pressure limits of system pipeline.
  5. Consider NPSH conditions to prevent cavitation under corrosive service.

✔ Final model configuration should be determined based on chemical compatibility, duty point, and sealing requirements.

Engineering Notes

  • Not suitable for slurry or media containing abrasive solids.
  • Avoid dry-running to protect fluoroplastic lining.
  • Thermal expansion of fluoroplastic must be considered in high-temperature applications.
  • Mechanical seal flushing plan may be required for volatile chemicals.

Compliance & Quality Assurance

  • Factory hydrostatic pressure test
  • Hydraulic performance curve verification
  • Fluoroplastic lining thickness inspection
  • Shaft dynamic balance test
  • Optional third-party inspection available

 Safety Notice

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