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
