For the Safe and Correct Handling of the Pump
• Before use of the pump, read carefully this "Safety Section" to prevent accidents and to
avoid the damage or loss of other assets.
• Observe and abide by the instructions described in this "Safety Section". These instruc-
tions are very important for protecting pump users or other persons from hazard or
from loss of assets.
• Meaning of symbols
Following two symbols describe the extent of hazards and loss which may brought if the
instructions are not observed or if the pump is wrongly used.
Following two symbols describe the content to be observed.
SAFETY SECTION

Warning
•Magnet field danger
The magnet drive pumps contain very strong magnets. The strong magnet field
could adversely affect persons who are assisted by electronic devices such as
pacemakers etc.
•Always turn off power supply prior to maintenance works etc. Pay special attention
so that no other operator turns on by mistake the power supply while someone is
working on the pump. In a noisy or poor visibility environment, display a sign near
power supply switch to notify other person that someone is "WORKING" on the
pump. Power supply mistakenly turned on during maintenance works may lead to
personal injury. Each operator must pay special attention.
•Wear protectors
When piping is removed or pump is disassembled/assembled, wear protective gear
such as safety goggles and protective gloves etc.
•Lifting pump
When pump is lifted, apply chain or belt to eye bolt and motor to keep the pump &
motor horizontally.
•No remodeling
Remodeling of pump may result in serious personal injury or damage of the pump.
Do not attempt remodeling pump because it is very dangerous.

No Remodeling
•Dangerous liquid
When the pump is used to transfer dangerous liquids mentioned as below, the
pump must always be checked and watched so that the liquid can not be leaked.
The operation of pump leaking the liquid may result in personal injury, explosion or
fire accident.
•Explosive or flammable liquids
•Corrosive or stimulus toxic liquids
•Liquids harmful to human health

CAUTION
•Attention to magnetic force
This pump employs strong magnets. Special attention must be paid not to be injured
by attracting force of magnets. Follow the procedure "Disassembling and
Assembling" when the maintenance works are done.
•Do not run pump dry
Do not run pump dry (without liquid). If the pump run dry, heat is generated by rub-
bing, which causes pump damage. If the pump is operated with suction side valve
closed, the pump runs dry.
•Countermeasures for static electricity
When low electric conductivity liquid such as ultra-pure water and fluor inactive liq-
uid (e.g. Fluorinert™ are handled, the static electricity may be generated in the
pump, which may cause static discharge and pump break down. Take countermea-
sures to avoid and remove the static electricity.
•Qualified operator
The pump must be handled or operated by the person who has enough knowledge
and well acquainted with the pump.
•For specified application only
The use of pump in any application other than those clearly specified may result in
the failure or damage of the pump.
Do not run dry
•Disposal of used pump
Disposal of used or damaged pump must be done in accordance with local laws and
regulations. (Consult a licensed industrial waste products disposing company.)
•Ventilate the site
When handling the liquid which may generate toxic gas, safety measures such as
ventilation must be taken to prepare for the accidental liquid leakage.
•Countermeasure to liquid flowing out
Protective measurement must be taken against liquid flowing out caused by dam-
age of pump or pipe by accident. Also, appropriate measurement must be taken so
that the liquid can not directly flow out on the ground.

After unpacking of the pump, check the following
points.
(1) If the product is ordered one.
Check model code, discharge capacity, discharge
pressure, voltage which are written on name-
plate of pump and motor to see if they conform
to your order.
(2) If the product is not damaged or bolts are not
loosened during transportation.
(3) If accessories are attached.
Standard accessories:
Bolts for back pull-out M12 ◊ 100: 2pcs

1. Permissible pressure
Permissible pressure of the pump is 1 MPa. Pay attention so that the pump discharge pressure does not
exceed this figure.
2. Slurry containing liquid
Basically slurry containing liquid can not be handled but SiC bearing type (KK type) can handle it in the fol-
lowing conditions:
•Slurry concentration up to 5 wt%
•Slurry hardness up to 80 Hs
•Slurry size up to 50 µm
3. Performance change caused by specific gravity and viscosity of liquid
When specific gravity and viscosity are larger than water, shaft power, discharge capacity and discharge
head will change depending on specific gravity and viscosity of pumped liquid. The pump was made and
shipped according to the information given to IWAKI. If the liquid condition is changed, ask and confirm
IWAKI to use the pump without problem.
4. Influence by liquid temperature
The chemical liquid changes its viscosity, vapor pressure and corrosivity according to the temperature
change. Pay attention to the change of liquid characteristics.
3. Conditions to be used
Liquid temperature range: ETFE material type 0 - 105 deg. C
PFA material type 0 - 120 deg. C
Ambient temperature range: 0 - 40 deg. C
Ambient humidity range: 35 - 85% RH
Note: For temperature range of each chemical liquid, refer to Chemical Resistant Table on booklet
"Technical Information on MDM Series".
