The products are widely appl icable to:

petrochemical industry, acid or base making, non-

ferrous metal metallurgy, acid-cleaning technique in

car-manufacturing, rare earth separation, pesticides,

dyes, medicines, papermaking, galvanization, and

radio industry, etc.

Service temperature: -20 ~100 .℃ ℃

Application

Magnetic Pump Series

Leak-proof design

Operating principle

Strong and sturdy pump housing

No shaft seal. Utilize magnetic coupling indirect driving, which

free you from the leak problem and will not contaminate the

site.

Because the pump's liquid carrying part is made of

Fluoroplastic alloy it can continually carry acid, base, or

strong oxidizer at any concentration without any damage.

In the driving device the initiative magnet junction box is

directly installed onto the motor shaft. The pump chamber is

totally sealed, and is propelled to rotate by the magnetic

impeller on the magnetic coupling indirect driving pump shaft,

its structure tight, safe, and energy-saving.

Though the liquid-touching part is made of fluoroplastics, the

pump enclosure is made of metal, so the pump can sustain

the pipe's weight and mechanical shock.

Model

The IMD series magnetic drive pump is without shaft seal and utilizes the magnetic coupling indirect driving, totally eliminating leakage. The IMD series magnetic drive pump employs separation sleeve made of the state-of-the-art materials and has high-strength mechanical property, eliminating the magnetic eddy current phenomenon of general magnetic pump. The IMD series magnetic drive pump employs the exclusive pull-back structure, and a single person can easily conduct inner inspection and component changing, with no need to disassemmble the pipes, wich greatly helps daily inspection and maintaining work.

Magnetic pump series

Application3 IMD series magnetic pump, flow rate: 1~160 m /h; pump lift:

17~62m, applicable to the carrying of caustic, inflammable, explosible, toxic, or volatile chemical mediums.

Service temperature: -20 ~100 . Idle running is forbidden.℃ ℃

The ZMD series self-priming magnetic pump amply combines the excellent features of both the self-priming pump and the magnetic pump, and it has both the self-priming property and do away with shafting seal, and it utilizes the magnetic coupling indirect driving, totally eliminating leakage. The ZMD series magnetic drive pump employs separation sleeve made of the state-of-the-art materials and has high-strength mechanical property, eliminating the magnetic eddy current phenomenon of general magnetic pump. The ZMD series magnetic drive pump employs the exclusive pull-back structure, and a single person can easily conduct inner inspection and component changing, with no need to disassemmble the pipes, wich greatly helps daily inspection and maintaining work.

Notes on the use of ZMC self-priming magnetic pump, FZB self-priming pump

Installation instructions and connection requirementsMake the concrete foundation according to basic dimensions, and simultaneously bury in the foundation bolt. Put the machine assembly on the foundation and make sure the pump is level, then tighten the foundation bolt. The pump should be near the water tank as much as possible.The diameter of the pump's liquid inlet duct should not be larger than what is required, and the length of the liquid inlet duct should not be more than 5m, the smaller the better but also under the requirements. A filter net should be installed at the bottom of the liquid inlet duct, so as to prevent large pellets or litter from entering into the pump housing and damaging the impeller or affecting the pump's running, and the filtering area should be 3 to 4 times larger than the section area of the duct.A value must be installed in the pipeline of the pump's liquid outlet duct to adjust the flow rate, as that the pump works under the specified flow rate, avoiding the inoperation of the pump due to overflowing. The diameter of the liquid outlet duct should not be smaller than what is specified, the larger the better but also under the requirements. The length of the liquid outlet duct must be larger than 1.5 times of the length of the liquid inlet duct, the longer the better if possible.The weight of the liquid inlet and outlet duct should not be relied on the inlet and outlet flanges, and they should be fixed on their own brackets. The connection parts of the liquid inlet and outlet duct should be tight and air-proof, or else the self-priming function and the pump's normal running will be affected.

Directions for use and maintenance instructionsThe transporting of solid particles or easy-to-crystallize mediums by the self-priming magnetic pump is forbidden. It is not permitted to run continuously with the discharge outlet closed, and the lowest flow rate should be kept.While installing ducts, first install the inlet duct, after fill liquid fully install the outlet duct.After installation, plug in the the power and check whether the running of the pump is smooth by the point-action way, and check whether the rotation direction of the electric motor is the same as the change of direction label.Open about one-third of the outlet valve, then start the self-priming pump (by open the valve), after that slowly adjust the outlet valve until the pump reaches the specified flow range.5. When carrying the liquid, the flow rate, pump lift and the self-priming height should be within the specified range, and the margin should not be too large, or else there will be empty-sucking, which will cause the pump to be out of order.There should be no empty-sucking situation while the self-priming pump is running. Once empty-sucking situation occurs, liquid must be conducted before renew self-priming. Therefore, the user must have facilities to control the lowest liquid postion or employ someone to take care of it, so as to prevent the mediums in the water tank from being sucked empty.The self-priming pump cannot carry mediums which will produce many bubbles, and it cannot transport mediums which are mixture of air and liquid.While transporting easy-to-crystallize mediums, if the pump is not in use for some time, the pump chamber should be cleaned, and not crystallized mediums should ramain, so as to prevent damage on the pump when it is started again due to the drystallization; While restart the pump, liquid should be conducted in according to requirements before self-priming.9. When carrying generel no-crystal mediums, if the pump is restarted after a long period of no use, before restarting, it should be check that whether the liquid in the pump is enough. If not enough, fill it fully before self-priming.While the pump is placed liquid level in using or if it replaces the duct pump in using, the air valve or cushion valve should not be attached. If so, discharge the air valve or the cushion valve.The outlet duct of the pump should not be installed with check valve. If so, an air-bleed hole should be placed at the lower end of the check valve.The installation height for self-priming height is as follows: 3m for self-priming in clear water / density of the medium = actual self-priming height.
