BM Series Magnetic Drive Centrifugal Pump

BM Series Magnetic Drive Centrifugal Pump

Application

The BM series magnetic drive centrifugal pump features wetted parts primarily made of austenitic stainless steel. It is suitable for conveying liquids with a maximum pressure of 1.6 MPa, temperature not exceeding 120°C, viscosity less than 30 mm²/s, and free from ferromagnetic particles and fibers. For applications requiring system pressure above 1.6 MPa, temperature exceeding 120°C, or thermal insulation, our company can provide customized solutions.

Design Features

• Fully sealed, zero leakage, and pollution-free design.
• Hydraulic components designed with CFD simulation: wide flow channels, high efficiency, excellent anti-cavitation performance, and low radial force.
• Precision investment casting with silica sol medium-temperature wax technology: accurate dimensions, smooth passages, and higher efficiency.
• Process liquid self-cooling and lubricating of transmission components, eliminating the need for additional pipelines and reducing project cost.
• High-performance, high-temperature-resistant rare earth magnetic materials ensure sufficient magnetic torque.
• Special magnetic circuit design for large magnetic gaps in certain models for industrial applications.
• Only 1–2 sealing rings required, ensuring optimal safety.
• Non-eddy current isolation sleeve design improves pump efficiency.
• Options of direct-coupled or flexible coupling motor connection.
• Direct coupling saves cost and space, improves transmission efficiency, simplifies installation, and eliminates alignment. For power above 37 kW, coupling connection is recommended for easier maintenance.
• Multiple circulation modes: self-circulation, auxiliary impeller forced circulation, auxiliary impeller pressurized ring, and external circulation to meet different working conditions.
• Optional cooling or heating jackets for special process requirements.
• Compatible with standard Y, YB three-phase motors, DC motors, and permanent magnet motors.
• Enhanced rigid shaft system design improves deflection index, reduces vibration, and extends component lifespan.
• Two installation options: foot-mounted (standard type) and centerline-mounted (high-temperature type).
• Multiple flange standards available: ANSI, GB, HG, etc.
• Axial force floating balance design: axial thrust is balanced during operation, thrust bearing only bears load at startup, ensuring near-zero wear in long-term operation.
• Wetted components made of high-strength, corrosion-resistant materials with double bearing alignment structure and advanced hydrodynamic lubrication for reliability and durability.
• Special lubrication and cooling design: circulating eddy flow removes heat generated by eddy currents on isolation sleeve and lubricates sliding bearings, ensuring safe and stable pump operation.
• Inner and outer magnetic rotors are fully sealed, preventing corrosion and degradation in aggressive environments.
• Isolation sleeve designed for complete drainage during maintenance and automatic venting during startup; made from advanced austenitic stainless steel, Hastelloy, or titanium alloys.
• Modular component design ensures high interchangeability, reduces maintenance workload, and lowers operator technical requirements.
