The flow passage parts of BME magnetic pump are mainly made of austenitic stainless steel, and can also be equipped with non-metallic lining or hot solid plastic. This kind of pump is collectively referred to as metal magnetic pump, which is suitable for conveying large pressure of 1.6Mpa, temperature of no more than 120 ℃ and viscosity of no more than 30 ℃ × 10-6m2
/ s liquid without ferromagnetic particles and fibers. When the pressure of the conveying medium system is more than 1.6Mpa, the temperature is more than 120 ℃, and the supporting insulation measures are needed, the unit can carry out special design and manufacture.

Fully sealed, no leakage
The hydraulic components designed by CFD have wide flow channel, high efficiency, good cavitation performance and small radial force
The flow passage parts are molded by investment casting mould, with accurate size, clean and clean flow passage and high efficiency
Process liquid self cooling lubrication transmission parts, generally do not need additional pipeline system, project investment is small
High performance and high temperature resistant permanent magnet materials are selected to ensure sufficient magnetic torque
Magnetic circuit design and industrial application of large magnetic gap for some special products
The integrated pump only needs 1-2 sealing rings to ensure safety
The isolation sleeve design of low vortex flow makes the pump more efficient
The motor can be directly connected or connected by coupling
The direct connection of motor can save cost and space, with high transmission efficiency, convenient installation and no need of concentricity calibration. When the power exceeds 45KW, in order to facilitate maintenance, the form of coupling connection should be adopted
Multi circulation mode, self circulation, through the auxiliary impeller pressure circulation and external circulation, etc., to meet the transportation of different media
When the working condition needs, the cooling jacket or the jacket with heating and heat preservation can be added
Choose ordinary Y Series and Yb series three-phase motor, DC motor and permanent magnet motor
The optimized rigid shaft structure design has better deflection index and reduces the vibration of the pump
There are two forms of low foot installation and center line installation, which can be selected for different temperature media. The basic type adopts foot support, and the high temperature type adopts center support
Flange standard provides ANSI, GB and other options
The axial force of the pump is mainly balanced by the blade and self balancing structure, and the residual axial force is borne by the thrust bearing
If necessary, the auxiliary impeller is used for forced circulation to prevent bubble deposition and ensure circulation flow
The ceramic bearing with large thickness, heavy load and strong thrust is made of high purity (SiC content is more than 98.5%, silicon content is less than 1%) and highly corrosive silicon carbide material. The unique design of double bearing centering and positioning structure and advanced hydrodynamic lubrication structure ensure the reliability of pump operation and the service life of bearing
Special lubrication and cooling design: the internal circulation liquid flow is used to take away the heat generated by eddy current on the isolation sleeve and lubricate the sliding bearing, so as to automatically balance the axial force of the pump and ensure the safe operation of the pump. Reasonable structural design enables all internal circulation systems to have sufficient pressure and flow to ensure the stable operation of the pump
The inner and outer magnetic rotors are all sealed to prevent the corrosion of the magnet and the degradation of the characteristics and strength of the pump in the corrosive environment
The new inducer technology can reduce the required NPSH
The isolation sleeve has the ability of completely draining the medium (when the pump is stopped for repair) and automatically emptying (when the pump is poured before starting). It is generally made of excellent stainless steel by advanced technology
Modular parts design, good interchangeability
Protection and condition monitoring of magnetic pump
The magnetic pump can solve the problem of conveying easily dispersed materials in the industrial system. However, the pump may be affected by the unstable process conditions when it works, so the protective device is recommended
The connection between BME series magnetic pump and motor is shaft coupling type, and the pump body is installed with central support
Various types of monitoring and protection devices are provided by the pump industry
Anti dry run under flow Protector: it can prevent the pump from no-load or light load failure caused by no liquid at the pump suction, insufficient liquid flow, medium vaporization, cavitation, etc. When the working current is continuously lower than the set current limit, the protection alarm and the main power supply are cut off, and the action time is less than or equal to 10 seconds. The protector has the functions of over-voltage, under voltage, three-phase current unbalance and phase failure protection.
Flow monitoring: effectively protect the magnetic pump by monitoring the flow of the main circulation circuit.
In addition, we can also provide temperature monitoring, pressure monitoring, bearing monitoring and other measures according to customer needs to ensure the safe operation of the process system.
Quality assurance system:
Jinliu pump has passed ISO9001 quality management system certification. Advanced technology is the foundation of everything. Excellent quality is the eternal pursuit of jinliu people.
Excellent products, perfect quality assurance system, reliable equipment performance and effective solutions are the commitment of the company to customers.
The pump is mainly used in petrochemical industry, fine chemical industry, chemical power industry, metallurgy industry, food and pharmaceutical industry and harsh special process flow, just like the heart of the process, safe and reliable operation without leakage is necessary.
With more than ten years of experience in engineering technology and project management, through years of configuration of magnetic pumps for process units and continuous communication and exchange with customers, the company has been improving its pumps and seeking to help "made in China 2025".
Every pump has been strictly tested, and every part, component and assembly assembled has been inspected and evaluated in detail to ensure the quality of products.
Reasonable type selection is very important, to have a full understanding of the process involved, including the corrosion characteristics of the fluid, specific gravity, viscosity, temperature, vapor pressure, dissolved gas content and solid content, etc. the experienced engineers of the company will provide high-level technical consultation and after-sales service.
