The BM series magnetic drive centrifugal pump has flow passage components primarily made of austenitic stainless steel. It is suitable for transporting liquids with a maximum pressure of 1.6 MPa, temperature not exceeding 120°C, and viscosity not greater than 30 mm²/s, without containing ferromagnetic particles and fibers. When the system pressure of the transported medium exceeds 1.6 MPa, the temperature exceeds 120°C, or when insulation measures are required, our company can provide special customization.
Diameter: DN32~DN200
Flow rate: 1.25~400m3/h
Head: 8-125m
Temperature: -90 ℃~120 ℃
Pressure: 0-1.6MPa (high-pressure~42MPa)
Power: 0.55kW~132kW
Materials: 304, 316L, 2205, 904L, TC4, TA1, TA2, C-276, etc
Fields: petroleum and petrochemicals, fine chemicals, pharmaceuticals, new energy, and other fields
Fully sealed, no leakage, no pollution
CFD (Computational Fluid Dynamics) designed hydraulic components for wide flow channels, high efficiency, good cavitation performance, and low radial force
Flow passage components are precision-cast with silica sol medium wax casting technology for accurate dimensions and clean, smooth flow channels with high efficiency
Process liquid self-cools and lubricates the drive components, generally eliminating the need for additional piping systems, reducing project investment
Uses high-performance, high-temperature-resistant rare earth permanent magnet materials to ensure sufficient magnetic torque
Special magnetic circuit design with large magnetic gaps for industrial applications in some special products
Only 1-2 sealing rings required for the entire pump, ensuring optimal safety
Low eddy current isolation sleeve design for higher pump efficiency
Option for direct motor coupling or coupling structure
Direct motor coupling saves cost and space, has higher transmission efficiency, easy installation, and requires no alignment; for power above 37 kW, coupling connection is recommended for easier maintenance
Multiple circulation methods including self-circulation, auxiliary impeller forced circulation, auxiliary impeller pressurized circulation, and external circulation to meet different working conditions
Cooling or heating insulation jacket structure can be added if required by working conditions
Optional Y, YB series three-phase motors, DC motors, and permanent magnet motors
Optimized rigid shaft system design for better deflection index, reducing pump vibration, and extending the life of shaft system components
Two installation forms: foot-mounted and centerline-mounted for different temperature mediums, with the basic type using foot support and the high-temperature type using center support
Multiple flange standards such as ANSI, GB, HG available
Axial force floating balance structure design ensures that the axial force is fully balanced during pump operation; thrust bearings only bear axial thrust during pump start-up, resulting in almost zero wear during long-term operation
Shaft system components made of high-strength, highly corrosion-resistant materials with a dual bearing alignment structure and advanced fluid dynamic lubrication structure to ensure pump operational reliability and extend the life of shaft system components
Special lubrication and cooling design: circulation fluid carries away heat generated by eddy currents on the isolation sleeve and lubricates the sliding bearings, ensuring safe pump operation
