BMG SERIES VERTICAL MAGNETIC DRIVE CENTRIFUGAL PUMP IS A NEW TYPE OF VERTICAL STRUCTURE MAGNETIC PUMP DESIGNED ON THE BASIS OF VERTICAL PIPELINE PUMP. Through the perfect combination with magnetic drive, it can achieve the requirements of liquid transportation without leakage.
It has the advantages of vertical pipeline pump: vertical installation, compact structure, small space occupation area; The inlet and outlet caliber is the same, and in the same axis, can be used as a part of any pipeline, convenient installation; The conveying medium in the pipeline is pressurized, and the original vertical pipeline pump can be directly replaced, which is convenient for users to replace.
The traditional vertical magnetic pump due to the influence of the internal rotor weight lead to its axial force, axial force balance technology is difficult, we overcome this problem through technical optimization design, using a special axial force balance scheme, the use of the pump in the operation of the internal rotor in the floating state, thrust bearing force is almost zero, to ensure the overall service life of the pump.
The traditional vertical magnetic pump can not fully exhaust the pump, it will cause short dry operation in the process of starting and running, and it is easy to cause the internal parts of the magnetic pump to burn out and other equipment failures in the long run. The magnetic drive component structure of BMG series vertical magnetic drive centrifugal pump has been ingeniously redesigned, which can completely drain the gas in the pump chamber, so that the pumping medium can fully fill the pump chamber.
Fully sealed, no leakage, no pollution;
CFD design hydraulic components, wide flow channel, high efficiency, good cavitation performance, small radial force;
The flow-through parts are made of fine casting mold and silicone sol medium temperature wax casting process. The size is accurate, the flow channel is fresh and clean, and the efficiency is high.
Rare earth permanent magnetic materials with high performance and high temperature resistance are selected to ensure sufficient magnetic torque;
The whole pump only needs 1-2 sealing rings to ensure the best safety;
Low eddy current isolation sleeve design, pump efficiency is higher;
Direct motor or coupling structure can be selected;
Multi-circulation mode, self-circulation, auxiliary impeller forced circulation, auxiliary impeller pressure circulation and external circulation, etc., to meet the different conditions of medium transportation;
When the working conditions need to increase the cooling or heating insulation jacket structure;
Optional ordinary Y, YB series three-phase motor, DC motor and permanent magnet motor;
