Pump

The high-altitude performance bucket bag shielded electric pump is a special fluid conveying equipment that integrates cutting-edge shielding technology and high-altitude anti cavitation design. It is specially developed to solve the problem of cavitation under harsh working conditions and meet the requirements of leak free conveying. The high-altitude performance bucket bag shielded electric pump adopts an integrated sealing structure of "motor pump body", combined with a unique bucket bag flow channel design and high-altitude enhancement technology. While ensuring absolute no leakage, it greatly improves the anti cavitation performance and can stably transport various liquid media that are flammable, explosive, toxic, highly corrosive, and prone to vaporization. It is widely suitable for key transportation links in high-end industrial fields such as petrochemicals, nuclear power, fine chemicals, and pharmaceuticals, and is the core power equipment to ensure safe, efficient, and continuous operation of the system.

Core advantage: High altitude anti cavitation, safe and leak free

1. Super high altitude performance, overcoming the problem of cavitation

For working conditions that are prone to cavitation, such as easily vaporized media, high-altitude environments, and high negative pressure suction, the product adopts an optimized impeller inducer design and bucket bag flow channel structure, which significantly reduces the cavitation allowance (NPSHr as low as 0.3m), effectively suppresses the erosion of pump components by bubble generation and rupture, and significantly improves the operational stability and service life of the pump. Even under harsh conditions such as large fluctuations in medium temperature and unstable suction pressure, bucket bag shielded electric pumps can still maintain high efficiency in conveying, completely solving the problems of increased vibration, noise, and flow attenuation caused by cavitation in traditional pumps.

2. Innovative bucket bag structure to enhance conveying adaptability

The unique bucket shaped bag cavity design not only optimizes fluid dynamics characteristics, reduces channel resistance losses, but also enhances adaptability to media of different viscosities. Compared to traditional structures, bucket bag structures can achieve smooth introduction and export of media, reduce vortex generation, and enhance the pump's resistance to impact loads. They are suitable for conveying scenarios containing small amounts of suspended particles, high viscosity, or easily crystallized media, balancing conveying efficiency and smooth operation.

3. Fully sealed and leak free design, ensuring safety and environmental protection

The bucket bag shielded electric pump adopts the classic integrated sealing structure of shielded electric pumps, eliminating traditional mechanical sealing devices. Through the double isolation of stator shielding sleeve and rotor shielding sleeve, the motor rotor and stator are completely enclosed in the pressure shell filled with the conveying medium, retaining only the static sealing structure, achieving absolute leak free conveying. This design fundamentally eliminates the risk of leakage of toxic, harmful, flammable, and explosive media, effectively avoiding safety accidents and environmental pollution, and fully complies with the strict safety and environmental protection standards in the high-end industrial field.

4. Low noise and energy-saving, with extremely low operation and maintenance costs

The motor of the bucket bag shielded electric pump eliminates the traditional cooling fan and adopts a circulating cooling method of conveying medium, combined with graphite sliding bearings (optional silicon carbide SIC superhard material), to achieve ultra-low noise operation (noise value ≤ 65dB (A)), suitable for clean workshops, precision chemical parks and other scenarios with high environmental noise requirements. Bearings rely on self-lubricating conveying media, eliminating the need for regular manual refueling. The number of parts is only 30% of traditional mechanical seal pumps, significantly reducing daily maintenance workload and costs. The designed service life can reach more than 10 years and supports 24-hour continuous operation.

Core technical features

-Integrated structural design: The motor and pump body of the bucket bag shielded electric pump are coaxially integrated, with compact size, light weight, small footprint, no need for coupling alignment, easy installation, and can be installed horizontally or vertically to meet different pipeline layout requirements.

-High quality corrosion-resistant material selection: The shielding sleeve of the bucket bag shielded electric pump is made of non-magnetic and corrosion-resistant materials such as 304L and 316L stainless steel, with a thickness precisely controlled between 0.2-1mm, balancing corrosion resistance and low eddy current loss; The overcurrent components can be customized with high-end materials such as Hastelloy and titanium according to the characteristics of the medium, fully resisting the erosion of strong corrosive media.

-Intelligent safety protection system: The bucket bag shielded electric pump is equipped with a bearing wear monitor, overcurrent protector, overheat protector, and no liquid dry running protection device, which can monitor the operating status in real time. When the bearing wear exceeds the standard, the current is abnormal, the temperature is too high, or there is no liquid idling, it will automatically shut down for protection, avoiding equipment damage and system failure.

-Wide working condition adaptability: The bucket bag shielded electric pump can adapt to a medium temperature range of -196 ℃ to 450 ℃, with a design pressure of up to 6.3MPa, a flow coverage of 0.1-600m ³/h, and a head of up to 800m. It can meet the transportation needs under different harsh working conditions and has strong working condition adaptability.
