MP polypropylene plastic magnetic drive centrifugal pump

Sealless magnetic-drive centrifugal pump engineered for leak-free handling of aggressive, hazardous and polluting liquids. The pump’s magnetically coupled design eliminates a mechanical shaft seal, producing a fully enclosed fluid path to prevent leaks and reduce environmental risk.

Key features

• Sealless magnetic drive: no shaft seal, fully sealed pump body for zero-leak operation and reduced maintenance.
• Materials of construction: available in reinforced polypropylene (FRPP) or PVDF for excellent chemical corrosion resistance.
• Flow range: 11 to 220 L/min, suitable for a wide range of transfer and circulation duties.
• Inlet/outlet options: hose connections or threaded connections for flexible installation.
• Temperature limits: FRPP versions rated for fluids up to 80 °C; PVDF versions rated up to 100 °C.

Principal components and materials

• Pump casing / isolating cover: FRPP
• Impeller assembly: FRPP with strontium ferrite magnets
• Active and passive magnets: strontium ferrite
• Pump shaft / thrust ring: alumina ceramic (wear- and corrosion-resistant)
• Shaft bushing: carbon-fiber filled PTFE
• Sealing rings: FKM or EPDM (material options based on chemical compatibility)

Benefits

• Zero-leak containment minimizes environmental contamination and product loss.
• Chemical resistance of FRPP/PVDF and inert internals make it suitable for acids, alkalis, solvents and many aggressive media.
• Low maintenance: magnetic coupling removes dynamic seal wear and reduces downtime.
• Ceramic shaft and PTFE bushing provide long service life in abrasive or corrosive fluids.

Typical applications

• Chemical dosing and transfer
• Corrosive liquid handling (acids, alkalis, solvents)
• Electroplating, surface treatment and pickling lines
• Wastewater and effluent transfer
• Circulation in chemical reactors and heat exchangers
