Self-Priming Magnetic Centrifugal Pump

Sealless Chemical Transfer with Reliable Suction Lift

Self-priming magnetic centrifugal pumps in polypropylene (PP) and PVDF combine the safety of leak-free magnetic drive technology with the ability to lift corrosive chemicals from sumps, underground tanks, and drums. By eliminating mechanical seals and allowing installation above the liquid level, these pumps provide a robust solution for hazardous fluid transfer where flooded suction is not possible.

Self-priming suction lift Sealless magnetic drive PP & PVDF options Reduced maintenance

Key Features

  • Self-priming capability — automatically evacuates air from the suction line to lift fluid from below the pump centerline
  • Sealless magnetic drive — eliminates mechanical shaft seals, preventing leaks and fugitive emissions
  • Corrosion-resistant materials — available in PP for broad chemical compatibility and PVDF for aggressive acids and higher temperatures
  • Installation flexibility — ideal for applications where the pump must be located above the tank or in space-constrained areas
  • Reduced maintenance — fewer wear parts and no seal cooling or replacement required

Typical Applications

  • Chemical unloading from IBCs, drums, and tanks located below the pump
  • Sump and pit evacuation in water treatment and chemical processing
  • Transfer of acids, alkalis, and corrosive reagents in surface treatment and mining
  • Recirculation of process fluids in non-flooded suction layouts

Technical Considerations

To ensure optimal performance, please provide the vertical suction lift height, horizontal piping length, fluid type, temperature, and required flow rate. Our engineering team will validate the self-priming limits and recommend the correct material (PP or PVDF) and pump configuration for your specific installation.

Overview & key advantages

  • Self-priming: typical vertical suction up to 4 m within ~2 minutes.
  • Leak-free: magnetic coupling — no shaft seal / no mechanical seal.
  • Corrosion-resistant wet end: PP for general duty; PVDF for stronger chemical resistance.
  • Air-liquid separation design improves priming stability and reduces nuisance interventions.
  • Idle capability: designed for better tolerance to intermittent operation vs. conventional self-priming pumps.
Selection guidance: choose PP or PVDF based on chemical compatibility, temperature, and concentration. Provide your fluid, temperature, and duty point (flow/head) and we will confirm the best configuration.

Operating notes (typical)

  • Self-priming: best performance with correct suction piping and minimal air leaks.
  • Liquids: for clean to lightly contaminated liquids (consult for solids/abrasives).
  • Startup: ensure suction line is tight; prime chamber must be configured per installation.
  • Leak-free drive: magnetic coupling (no shaft seal) reduces maintenance and emission risk.
  • Protection: dry-run/overheat protection recommended for high-risk duty cycles.
  • Materials: PP or PVDF wet end; elastomers (FKM/EPDM) per chemical and temperature.
For accurate selection, share your fluid name/concentration, temperature, desired flow, and discharge pressure/head.

Chemical transfer (above-tank installation) Tank unloading / circulation Surface treatment / plating lines Filtration skids Acids & alkalis handling Intermittent duty systems
