CAF series
Fluorine-lined Chemical Centrifugal Pump with Magnetic Drive is designed and developed according to API685-2000 standard, and introduces high-tech products with international leading level developed by German technology. Applying the principle of magnetism, the medium is enclosed in a stationary isolation sleeve to achieve contactless transmission of torque, eliminating the shaft seal device (filler seal or mechanical seal) of the conventional centrifugal pump, and replacing the dynamic seal with a static seal to achieve full sealing and no New chemical process pump leaking. The flow-through parts are all made of fluoroplastics, which can transport any concentrated (strong) acid, alkali, oxidant and other corrosive media. The isolation sleeve is made of special materials to produce high-strength mechanical properties, eliminating the magnetic eddy current phenomenon of the magnetic pump. The performance meets international standards, can replace expensive stainless steel, special alloy materials, imported chemical pumps, industrial environmental protection equipment to eliminate industrial leakage, prevent pollution, and ensure environmental purification, and is included in green chemical equipment.
Product features
● The structure and performance of the magnetic transmission device is excellent: it adopts a unique magnetic drive device with dense magnetic coupling and magnetic magnetic coupling. This coupling structure is widely used in the world's advanced countries. Compared with the driving device with phase-coupled magnetic circuit coupling, it has the advantages of
small volume, large torque, small eddy current, high transmission efficiency, good reliability (in the magnetic circuit structure, eliminating the possibility of slippage), and completely overcomes their defects. .
● The
efficiency of the pump is generally higher than 5-10% of the similar products in the world's advanced countries: the magnetic drive device adopts the patented technology to carry out serialized optimization design, and combines the unique process and manufacturing to affect the efficiency of the magnetic pump. The various losses are reduced to a minimum, so that the efficiency of the centrifugal magnetic pump is substantially the same as the efficiency of the shaft seal.
● Low natural wear rate and
long maintenance-free period: It has a unique magnetic pump axial force balance system, which makes the axial force almost zero, which can make the thrust bearing end face and the sliding bearing end face only in the long-term operation of the pump. It produces very slight mechanical friction, so the natural wear rate is low, the failure rate is low, and the maintenance-free cycle is long.
● The pump body is made of
carbon steel lining fluoroplastic (PTFE, FEP, PFA). The inner rotor, pump cover, impeller, isolation sleeve and other over-current components are surrounded by metal inserts and fluoroplastic (PTFE, FEP, PFA) is integrally sintered and pressed;
● The pump shaft is made of CR13 outer fluoroplastic (PTFE, FEP, PFA) and sintered. It does not cause the problem of the traditional magnetic pump pump shaft fracture.
● The magnet uses a new type of permanent magnet, which has good magnetic properties, high temperature resistance and no demagnetization;
● Bushings and plain bearings are made of highly wear-resistant silicon carbide (SSIC) and have
lubrication grooves to ensure the service life of the pump.
● The seal adopts a closed static seal and is designed with a secondary seal. When the medium leaks, it will not come into contact with the atmosphere. Effectively solves the media leak. Eliminates the need for separate lubrication and cooling water, reducing energy consumption.
● From the coupling drive to synchronous drag, there is no contact and friction.
Low power consumption,
high efficiency, and damping damping effect, reducing the impact of motor vibration on the pump and the impact of the cavitation vibration of the pump on the motor;
Use of the product
Used in the chemical, pharmaceutical, petrochemical, water treatment, pulp and metal processing, and waste treatment/recycling industries to transport corrosive, hazardous, contaminated or clean media.
The CAF series is considered to be:
● Suitable for media under difficult operating conditions
● Stainless steel is not enough to resist the corrosive medium
● Pumps for replacing expensive rare metals (Hall's all alloys, Monel, enamel, etc.)
● For solids, crystalline, toxic, high temperature media or other toxic media
It can be widely used in the production process of chemical, petrochemical, pharmaceutical, printing and dyeing, etc., and the cleaning liquid with the specific gravity is not more than 1.84. It is especially suitable for the transportation of flammable, explosive, toxic, harmful, corrosive and valuable liquid media. . It can transport inorganic acids and organic acid solutions such as sulfuric acid, nitric acid, hydrochloric acid and phosphoric acid at various temperatures and concentrations;
The non-leakage magnetic pump is an ideal green chemical equipment, which will bring high economic benefits to the industries such as chemical industry, petrochemical, pharmaceutical and printing and dyeing industries, such as increasing production and saving, eliminating pollution, protecting the environment, safe production and labor protection. Social benefits. The CAF series of magnetically driven centrifugal chemical process pumps are standard leak-free centrifugal pumps that can replace centrifugal pumps and shielded electric pumps with shaft seals.
