In the fields of p etroleum, chemicals, war industry and phar­  maceutic als etc., ther e are often n eeds t o hand le some corrosive

liquids. For this reason we dedicate ours elves to the development 

an d rese arch o f fully seale d, lea k­tigh t and c orrosion­resisting

centrifugal pumps. Magnetism­driven silent seal technology performs 

leak­tight seal in pump industry.  Magnetism­driven centrifugal pump (magnetic pump for short) 

is a late model uses the theory of modern magnetics. The noncontact 

transfer of torq ue is a ctualized by the ma gnetic force of permanent  magnet. Namely, when motor drives outer rotor (outer magnet steel) 

assembly rotating, inner rot or (inn er magnet st eel) assembly will 

rotate synchronously with impeller driven by magnetic line of force

through spacer sleeve under the function of magnetic field. As me­ 

dium is closed in the actionl ess spacer sleeve, leak­tight delivery of  medium can be effected, ma king it a new­style industrial pump of 

fu ll seal and no leakage and pollu tion, a nd awa y from the trouble

of leakage at sh aft seal borne by mechanical drive pumps.  Mag netic pump is an e nvironmental­friend ly sol ution t o the

ph enomena of bleedi ng, emitting,  dropp ing an d leaking, th us to

effect "l eak­tight workshop" and "eak­tight fac tory" for saf e and

civilized production. They a re widely use d in the industries of pe­ 

troleum, chemi cals, pharmaceutica ls, prin ting and dyeing, el ectro­ 

plating, foodstuff, environment protection and etc. to handle corrosive

liquid not containing scrap irons, especially inflammable, explosive, 

volatile, toxic a nd pre cious liquids.  Magnetic pumps are provided with CQ, CQF, ZCQ, CQB, CQB­F,  CQB­G, IMC, ZBF, MP, MPH, CQG series conforming to ISO2858,  GB5662 and JB/T7742­1995. Using the most superior hydraulic model, 

all magn etic pumps a bove a re featured by high efficiency, energy

saving, steady performance, simple structure, easy installation, small 

occupation of floor, c onven ient disassembly an d main tenanc e and

low nois e, making th e mop timal for the industries of petro leum, 

chemicals, pharmaceuticals, electroplating, electronics, environment 

protection and etc.

在石油、化工、军工、制药等领域 中，经常存在着一 些输送腐蚀性液体的场所，因此研制和开发全密封、无泄

漏、抗腐蚀性能强的离心泵是我们关心和研究的方向。磁

力传动静密封技术在泵领域的应用显示出其零泄漏的密封

特性。 磁力传动离心泵 简称磁力泵 是应用现代磁力学原理， 利用永磁体的磁力传动实现扭矩的无接触传递的一种新型

泵，也就是电 机带动外转子 即外磁钢 总成 旋转时，通过

磁场的作 用磁力线 穿过隔离套带动 内转子 即内磁钢 总成

和叶轮同步旋转，由于介质封闭在静止的隔离套内，从而

达到无泄漏抽送介质的目的，彻底解决了机械传动泵的轴

封泄漏而设计的全密封、无泄漏、无污染的新型工业用泵。 磁力泵是化工流程中杜绝跑、冒、滴、漏现象，消除

环境污染，创造“无泄漏车间”、“无泄漏工厂”，实现

安全、文明生产的理想用泵。广泛应用于石油、化工、制

药、印染、电镀、食品、环保等企业的生产流程中输送不

含铁屑杂质的腐蚀性液体，尤其适用于易燃、易爆、易挥

发、有毒和贵重液体的输送。 磁力泵产品有 、 、 、 、 、 、 、 、 、 、 等 系列， 产品符合 国际标准 、国家标 准 和 的有关要求 ； 以上各种系列磁力泵都采用最优秀的水力模型，达到了高

效、节能、性 能稳定等优点。 而且结构 简单，安装简便 ， 占地面积小，拆卸维修方便，噪音低，是石油、化工、制

药、电镀、电子、环保等行业的首选产品。

1. Magnetic pump should be horizontally installed, but not upright. Plastic  pump is not able to endure the weight of pipeline. In case of special occasions 

requiring upright installation, motor should be kept upward.  2. When liquid level is higher than the centerline of pump, turn on the  valve of intake pipe before start; when liquid level is lower than the centerline, 

a bottom valve should fitted to the pipeline.  3. Check before operation to make sure that motor rotates flexibly without 

jamming and abnormal sound, and that all fasteners are not loosened.  4. Check whether motor rotates in accordance with the direction sign.  5. After motor is started, slowly turn on discharge valve. When pump enters 

normal working state, adjust the discharge valve to the required opening.  6. Before pump stops working, turn off discharge valve first, and then the  valve of intake pipe.

INSTALLATION AND OPERATION OF MAGNETIC PUMP  一、磁力泵应水平安装不宜竖立，塑料泵不得承受管路重量， 特殊垂直安装的场合，电机务必朝上。 二、抽吸液 面高于 泵轴心 线时，起动 前先开 吸入管道阀门； 抽吸液面低于泵轴心线，管道需配备底阀。 三、泵使用前应进行检查，电机转动要灵活 ，无卡滞及异常

声响，各紧固件无松动现象。 四、检查电机旋转方向与转向标记是否一致。 五、电机启动后，缓慢打开排出阀，待泵进入正常工作状态

后，再将排出阀调到所需开度。 六、泵停止工作前，应先关闭排出阀门，然后关闭吸入管阀

门。

1. As the cooling and lubrication of magnetic pump`s bearing depends on

the medium to be handled, that`s why unloaded operation is absolutely prohibited,  Meanwhile, pay close attention to avoid the unloaded operation after re­start due 

to power cut in process.  2. If the mediums to be handled contain solid particles, then there should

be a filter net at the entrance of pump. If there are ferom agnetic particles contained in mediums, a magnetic filter should be fitted (available in factory for

your options).  3. The mediums to be handled, as well as their temperature, should be kept  within the allowed scope of pump material (please consult with relative technical 

department). The service temperature of engineering plastic pump should be  <60 , inlet pressure not greater than 0.1MPa, maximum working pressure at  0.6MPa; the service temperature of metal pump should be <100 , inlet pressure  not greater than 0.2MPa, maximum working pressure at 1.6MPa.  4. For mediums easily deposited or crystallized, please flush immediately

after use to clear away the deposited liquid inside.  5. In case of any abnormal conditions (like large noise or violent vibration) occurred after long­time operation or during operation, disassemble the bearing

and end­face rotating ring for examination of abrasion. If the clearance between

bearing and axle sleeve is greater than 0.5­1mm, and axial crunkenness of impeller

from 2­3mm, then the bearing and axial rotating ring should be replaced.

1. When disassembling magnetic pump, the magnetic field radiated by inner

and outer magnet steel components may produce interference, and even harmful 

influence to heart pacemaker, credit card, computer disk, watch, precision instrument, meter and etc. 

a) The above articles should be kept over 1 meter away from magnetic parts.  b) The above­mentioned problems don`t happen to assembled overall magnetic 

pump, because there is provided with a magnetic loop shield for your reassurance.  2. When inner magnet rotor is leveled to outer magnet rotor axially, and due 

to magnetic force (especially the strong magnet of NdFeB or rare earth­cobalt),  users must take appropriate buffering measures to avoid work accidents like fingers  being clamped.

Warining: a) Pump motor should be safely earthed by a professional,  permanent sign as .  b) To avoid electric shock, the maintenance and cleaning  of magnetic pump should be done after power supply is cut off.
