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

instructions 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 Nonobservance or misapplication of the contents of

the "Warning" could lead to a death or heavy injury of

person.

Caution Nonobservance or misapplication of the contents of the

"Caution" could lead to a injury of person or damage of

assets.

Prohibited action or procedure is indicated. Inside or

near this circle, a concrete activity to be prohibited is

depicted.

Action or procedure which must be performed without

fail is indicated. Inside this circle, a concrete activity

to be performed is depicted.

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.

Power off

Wear protective

gear

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

Safety Section

- 3 -

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

rubbing, 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

liquid (e.g. Fluorinert™ are handled, the static electricity may be generated in the

pump, which may cause static discharge and pump break down. Take

countermeasures 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

damage of pump or pipe by accident. Also, appropriate measurement must be taken

so that the liquid can not directly flow out on the ground.

Safety Section

•Eliminate air in pump chamber

Before full operation of pump, run pump to eliminate air from pump chamber.

Above all when pumping liquid which easily generates bubbles (hydrogen peroxide,

sodium hypochlorite or so), eliminate air every time when pump is operated.

Operation of pump with air remaining in pump chamber may heat rubbing parts of

pump resulting in pump damage.

After unpacking, check the following points to confirm that

the delivered product and its accompanying parts and

elements are exactly what you ordered.

[1] Do the model and frequency indicated on the nameplate

conform to your order?

[2] Prior to the installation of the MDF-LMKK pump

(using SiC liner ring and mouth ring), remove the

cardboard pad inserted inside the suction port.

[3] Has the pump unit or any part of it been damaged or

bolts and nuts been loosened during delivery?

2. Description on body and label

Pump unit (liquid feeding section)

No self priming: Before operating the pump,

feed liquid through the suction

or dischargeside port.

Motor nameplate

Use only the power voltage specified on the

nameplate. (Follow applicable local power

regulations.)

"Rotation" indicator label

The arrow indicates the rotating

direction of the motor.

Always make sure that the motor

runs in the direction the arrow

indicates. (Refer to chapter

"Operation".)

Motor (Driver)

This motor provides power to the

pump unit.

Base

Pump should be fixed firmly.

Discharge port

Suction port

Drain port

Drain the discharged liquid into a

suitable container and follow the

applicable local regulations in

disposing of the liquid. Never

allow the discharged liquid to

flow directly onto the ground. "Never Run Pump Dry" label

Operating the pump without liquid will cause damage inside the

pump. Never operate the pump without liquid. (Refer to pump

model code u.)

CAUTION

When cleaning the pump, do not wipe the labels or the pump body with

solvent.

Pump specification nameplate

Pump must be operated according to

the specified conditions.

Operating condition of pump

[1] Allowable pressure

Graphs below show maximum pressure resistance of pump. Pump discharge pressure should not exceed the

max. allowable pressure.

[2] Slurries containing liquid

Liquid containing slurries can not be pumped as a general rule, however the pump with SiC bearing (KK type)

can handle liquid containing slurries max. 5% concentration, particle size max. 50 µ and hardness max. 80Hs.

Consult us in advance when you wish to handle liquid containing slurries.

[3] Specific gravity and viscosity of pumped liquid influence pump performance

Shaft power, discharge capacity and head are influenced by specific gravity and viscosity of pumped liquid.

Pump is manufactured based on the information of specification and operating condition given to us when

ordered. If the informed specification and condition will be changed, ask us for the possibility of usage before

you use the pump.

[4] Influence by temperature

Pump itself is not influenced by temperature change but pumped liquid changes its viscosity, vapor pressure,

chemical corrosion characteristics etc. according to the change of temperature. Therefore enough attention

should be paid to the change of temperature of pumped liquid.
