BMR series side-channel magnetically driven centrifugal pumps provide the best solution for many special pumping tasks with very low NPSHr, strong self-priming performance and vapor liquid handling capability, which can safely handle media close to saturated vapor pressure. It is widely used in refrigerants, liquid media mixed with a large number of gases, media in the pumping distillation column near the boiling point temperature and volatile hydrocarbons.
The head impeller has a very low cavitation residual value, and the secondary impeller uses the principle of liquid ring vacuum pump.
Strong self-absorption performance;
Capable of handling up to 50% liquid gas entrainment;
Modular structure design, less variety of spare parts, strong versatility;
The pump structure is compact, segment type can also be customized barrel shell, easy to maintain;
No dynamic seal, magnetic drive in line with API685 standard;
The magnetic materials are made of high quality rare earth permanent magnets, and the long-term operation is maintenance-free.
For small flow, high head;
The shaft system is made of high strength, high wear resistance corrosion resistant material, stable and safe;
Double isolation sleeve structure and leakage monitoring alarm can be configured to achieve dual security protection.
Diameter: DN25~DN300
Flow rate: 1-50m3/h
Head: 5-400m
Temperature: -90 ℃~250 ℃
Gas content: 0-50%
Materials: 304, 316L, 2205, 904L, TC4, TA1, TA2, C-276, etc
Fields: refrigerants, large amounts of mixed gas and liquid transported near the boiling point temperature, pumped into distillation towers, and volatile hydrocarbons, etc
BR series low cavitation intelligent centrifugal pump with automatic adjustment function, can be adjusted according to the amount of liquid inhaled, and has dry operation ability, can be automatic exhaust, very low cavitation allowance (< 0.1m). In view of the condition of cavitation, we have made great changes in the structure. In addition to high reliability and long life, the low installation height also saves a lot of equipment installation costs for the user. The pump has a very good performance in conveying boiling liquids and liquids containing gases, and is also a very good choice when the tank tank needs to be completely evacuated.
Flow self-adjustment: according to the input of the inlet pipe, and back pressure, automatically adjust the output flow, can be dry operation for a long time;
Cavitation resistant pumping: due to the special structural design and internal system pressure balance structure, changed the conventional pump NPSHr concept, high gas liquid, high boiling substance and easy to vaporize the material pumping will not produce cavitation, can also be used for easy vaporization medium unloading, without pit or barrel bag installation;
Vacuum pumping: vacuum tower pump, no additional gas phase balance pipeline and control device;
Intelligent: integrated and simple design, without any pressure, liquid level, throttle and other instrument control design, without independent liquid collection gas liquid sharing tank, without inverter control system and other complex structures;
Safe operation: in the case of interrupted flow and accidents, it can safely run dry without stopping the pump, and will not hurt the pump equipment and operators.
