Product Introduction

The CQB series stainless steel magnetic drive pump adopts casting technology for the shell, with a compact structure and a design pressure of 2.5Mpa. Both the inner and outer magnets are neodymium iron boron permanent magnets, and the impeller is connected to the inner magnet through the pump shaft. The CQB series magnetic drive pump is widely used in industries such as chlor alkali, chlorobenzene, chemical foil, acid washing, pesticides, papermaking, and steel. Capable of transporting highly corrosive media such as acids, alkalis, salts, organic solvents, etc. It can operate stably for a long time at temperatures ranging from -20 ℃ to 120 ℃. If the temperature is above 120 ℃ and below 350 ℃, you can choose our CQB-G pump model. For low-temperature locations with temperatures ranging from -180 ℃ to -45 ℃, customers can consult our company for low-temperature magnetic drive pumps, and choose according to their actual working conditions.

Product advantages

1.Our company's pump body adoptsCZStandard chemical process pump castings with a design pressure of2.5MpaEach pump body undergoes a pressure test, and even minor leaks will be recast in the furnace. The pump body has undergone three passivation treatments to ensure its natural color. Using the latest hydraulic design software to design hydraulic models with excellent performance is the top priority for ensuring long-term safe and reliable operation.

5.For the material of the shaft of the stainless steel magnetic drive pump, the material of the shaft can generally be selected according to the material of the overcurrent component. Common shaft materials include:304、316LTitanium alloy, HastelloyCAlloy, of course, there are also various other material configurations to adapt to different working conditions. Customers can consult our company in detail.

Structure Introduction

1、Two static sealing points ensure that even if the internal magnetic rotor components are damaged, there will be no leakage. For extremely dangerous places such as toxic, flammable, and explosive environments, a double isolation sleeve structure can also be used and a leakage alarm device can be installed. Customers can consult our company in detail.

2、The structure is simple and easy to disassemble, providing a more favorable guarantee for uninterrupted operation under working conditions. Our company can send technical personnel to the user's site for training, and customers can also send operators to our company for exchange and learning.
