The products are widely applicable 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.

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
Application
3IMD 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.

the parameters are not included in the table, our factory can realize them by improving the impeller.
2. If the status point flow rate is too small, the inlet should be connected to the return pipe, and for more specific information you can consult

Installation instructions and connection requirements
Make 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 instructions
The 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.
