Pump Features

  • Insulated composite cannister without eddy loss to achieve high pumping efficiency.
  • Super quality material and optimal structure secure the working pressure up to 25 bar.
  • Latest balancing drum design to minimize the axial thrust on shaft and bearing.
  • PT100 built-in is capable to monitor the coupling temperature rise.
  • Leakage prob is option to monitor any leakage from cannister.
  • Unique volute discharge to achieve high efficiency and robust pump body which small footprint enable the pump installation convenient and flexible especially in limit space.
  • Composite material applied on seal ring & sleeve with good wearresisting property, well lubricated by pumping medium to maintain impeller long lifetime.
  • Advanced hydraulic design ensure the complete drainage capable and support gas free operation.

 

Concept Features

  • Double radial guide vane to gain more compact shaft structure.
  • Innovated hydraulic pressure balance design to achieve minimum force on shaft, longer bearing life and higher pumping efficiency.
  • Casted hydraulic parts which is high reliability and anti-corrosion by variety material options.
  • Complete liquid drainage is capable by the latest pump hydraulic and structure design.
  • Advanced graphite composite material applied on sealing sleeve to obtain excellent lubricating performance.

 

Why choose magnetic drive?

  • 100% seal-less design – no leakage, no emissions
  • Ideal for toxic, hazardous, flammable, or valuable liquids
  • No seal system maintenance – reduced downtime and lower operating costs
  • Proven, reliable and efficient alternative to conventional shaft seal pumps
