BTM Series Magnetic Drive Canned Motor Pump

Product Description

The BTM Series Magnetic Drive Canned Motor Pump is a liquid magnetic drive canned pump with a double-shell design. All sealing points are static seals, requiring no additional auxiliary sealing devices, ensuring extremely reliable safety. It is widely used in petrochemical, chemical, pipeline pressurization, and liquefied gas engineering, and is suitable for volatile media such as liquid ammonia, LPG, anhydrous hydrogen fluoride, alkanes, hydrocarbons, liquid chlorine, titanium tetrachloride, and phosgene.

Design Features

• Double-shell vertical canned structure, with inner shell being single-stage sectional or multi-stage sectional. The pump casing withstands system pressure. The shell length and pump insertion depth depend on the NPSHr requirements of the installation. It can also be directly mounted on the medium storage container, eliminating the need for an external shell, as the container serves as the pump casing.
• Optimized hydraulic model with low NPSHr impellers, high efficiency, and wide operating range.
• The isolation sleeve is made of high-strength, high-resistance materials, resulting in low eddy current loss, high magnetic transmission efficiency, and minimal medium temperature rise.
• Double isolation sleeve structure with optional leakage monitoring and alarm system for dual safety protection.
• Compact structure, high parts interchangeability, economical, safe, and reliable.
• Complies with GB3215 and API685 standards.
• Magnetic materials made from high-temperature samarium-cobalt with strong corrosion resistance, excellent demagnetization resistance, irreversible demagnetization temperature, and long service life.
• Shaft wear parts are manufactured from corrosion-resistant, high-strength, high-wear materials, ensuring stability and safety.
• Axial force floating balance design: axial force is fully balanced during pump operation, thrust bearings only bear axial force at startup, ensuring almost zero wear during long-term operation.

Performance Range

• Diameter: DN40~DN200 (discharge diameter)
• Flow Rate: up to 800 m³/h
• Head: up to 400 m
