CQB magnetic pump has compact structure, beautiful appearance, small volume, low agitation, reliable operation, easy to use and maintain the product is widely used in: chemical industry, acid, alkali, smelting, rare earth, pesticides, dyes, pharmaceuticals, papermaking, electroplating, pickling, radio, scientific research institutes, national defense industry, etc. pumping acid, alkali, oil rare and precious liquids, poisonous liquids, volatile liquids, especially the leakage of flammable and explosive liquids. Pumping. It is more ideal to choose the matching explosion-proof motor.COB magnetic pump replaces the dynamic seal with static seal, which makes the pump chamber in a completely sealed state, canceling the shaft seal, using the magnetic coupling to drive indirectly, completely eliminating the trouble of dripping and never contaminate the use of the site. As the overflow part of the pump is made of “gas plastic alloy”, the pump can continuously convey acid of any concentration. It can continuously convey any concentration of acid, alkali, strong oxidizer and other corrosive media without damage. IMD type magnetic pump is a newly developed high power and high head magnetic drive pump, pump appearance and installation dimensions are designed and manufactured in accordance with (S0) international standards, the motor is directly coupled, supported by the intermediate bracket, compact structure, easy to dismantle, performance range of Q=6~130m3/ H=17~50m, pumps are using high-performance magnetic material “neodymium iron boron” as the inner and outer magnets. The pump adopts high-performance magnetic material “NdFeB” as internal and external magnets, and the isolation sleeve adopts imported non-metallic material, which greatly reduces the loss of magnetic eddy current, and it can transport the strong corrosive medium with high concentration and density more than 1.84t/m3, and the main parts are lined with steel F46, which makes the pump body with high strength, and it can resist corrosion of all strong acids and alkalis, and it adopts the structure of magnetic drive to prevent dripping and leakage, and it will never contaminate the site, which is especially suitable for the pumping of flammable, explosive, and explosive materials. It is especially suitable for conveying flammable, explosive, toxic, volatile and valuable media, and has replaced imported magnetic pumps in many projects. When the flow is small, high head when choosing magnetic pumps should choose IMD type magnetic pump.

Many purchasers in the procurement of chemical pumps will be compared to three, accurate calculation of the price of the pump, and then choose to be able to meet their own requirements and the lower price of the product. This method does save the initial purchase cost, and most of the products in the beginning can basically meet the needs of the use. But for the user, the pump in the use of the process plays a role far higher than the original purchase and the cost of it, so that we must be these pump problems and failures when the waste of time and maintenance costs are calculated to the overall cost; similarly, the pump will consume a lot of electricity in the process of operation, over the years, a small pump consumption of electricity is amazing. By some foreign pump manufacturers to sell out of the product tracking survey shows that the purchase price of a pump is actually only 5 to 10% of its life cost, the rest is from the maintenance and energy consumption, and then take into account the efficiency of its own use, noise, artificial maintenance, etc., our purchasing staff still have any reason to blindly pursue the low-priced products? Xinyuan initially committed to provide users with energy efficient pump products, care about the other 95% of the user (cost of use), and make special design! In fact, the same type of pump is basically the same as the original buried, inside the structure, components are similar, the biggest difference is reflected in the selection of components, workmanship and quality, and other products are not the same is that the pump parts cost difference is very significant, the gap is so large that the general public can not imagine. For example, a very small shaft seal, cheap one or two dollars can be bought, while the good products are tens or even hundreds of dollars, you can imagine the use of these two products manufactured by the quality and price difference between the products, and let people worry about is that in the early use of the process they are almost no difference. Hundreds of dollars or even thousands of dollars in price difference is reflected in the efficiency of the product, energy consumption and life expectancy. Short life, noise, leakage and other phenomena occur one after another, so that many users regret that they should not begin to choose cheap products. The use of the process of noise and high heat is actually valuable electrical energy is converted to useless kinetic energy (mechanical friction) and thermal energy, the actual effective work done is much less.

Magnetic pump selection to consider the viscosity of! Magnetic pumps in the selection process should be based on the nature of the enterprise’s production unit, its own condition and allowable conditions. Mainly from the medium delivery capacity, device head.
The nature of the medium, piping arrangement and operation running conditions and other aspects to be considered.
Selected according to the physical and chemical properties of the conveying medium conditions
The physical and chemical properties of the transport medium directly affect the pump performance, materials and structure, is one of the important factors to be considered when selecting.
Physical and chemical properties of the medium include: medium name, medium properties (such as corrosive, abrasive, toxicity, etc.), solid particle content and particle size, density, viscosity, vaporization pressure. If necessary, should also list the gas content of the medium, whether the medium is easy to crystallize.
2, according to the process parameters selection
Process parameters are the most important basis for selection of magnetic pumps, should be carefully determined according to the process and operational changes in the range. Such as flow, head is one of the important process parameters for pump selection, which is directly related to the production capacity and conveying capacity of the whole device.
(1) flow Q
Flow refers to the production of process equipment, the pump is required to transport the amount of media. Process personnel should give the normal minimum and maximum flow. Pump data sheet often only gives the normal flow rate and rated flow rate. Selection of magnetic pumps, the rated flow rate is required to be not less than the maximum flow rate of the device, or take the normal flow rate of 1.1 ~ 1.15 times. (2) head H
Value of the head value required by the process device, also known as the calculated head. Generally require the pump rated head for the device required head 1.05 ~ 1.1 times. (3) Inlet pressure and outlet pressure
Inlet and outlet pressure refers to the pressure at the pump inlet and outlet flange. The size of the inlet and outlet pressure affects the shell and shaft seal (isolation sleeve) pressure requirements (4) temperature T
refers to the pump’s inlet medium temperature, generally should be given to the magnetic pump inlet medium of the normal, minimum and maximum temperature values.
(5) device corrosion allowance NPSHa
Also known as the effective corrosion allowance.
(6) operating conditions
The operation state is divided into two kinds, continuous operation and intermittent operation.
3、Select according to the magnetic pump site conditions
Magnetic pump site conditions include.
(1) Installation location (indoor, outdoor, plateau, seaside)
(2) Ambient temperature.
(3) Relative humidity; and
(4) Atmospheric pressure; and
(5) Atmospheric corrosion conditions.
(6) Classification of hazardous areas
4、According to the system piping layout conditions for selection
The piping arrangement conditions of the system refers to the conveying liquid height, distance and direction, the lowest liquid level on the suction side, the highest liquid level on the discharge side, and some other data and piping specifications and their lengths, materials, pipe fittings specifications, quantity, etc., in order to carry out the calculation of the system head and the calibration of the cavitation margin.
5, according to the operating conditions of choice
Operating conditions are many, such as the medium (liquid) in the operation of saturated vapor pressure, suction side pressure (absolute), discharge side container pressure, altitude, ambient temperature, operation is intermittent or continuous, the pump position is fixed or movable.
The above basis, should be proposed by the user, or by the pump manufacturer to assist in proposing, and carefully fill out the magnetic pump data sheet or magnetic pump ordering advice sheet.
