MV Multistage Centrifugal Pump - Magnetically Driven
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
