use, read this section carefully for the prevention of personnel injury or property damage.

●

Observe the instructions accompanied with "WAR NI NG" or "CAUTION" in this manual. These

instructions are very important for protecting users from dangerous situations.

●

Th e symb ol s o n t his in stru c t io n m anu a l h ave the fol lowi ng m e an i n g s:

Nonobservance or misapplication of “Warning”

WARNING

sections could lead to serious accident which may

Nonobservance or misapplication of “Caution” sec-

CAUTION

tions could lead to personal injury or property dam­age.

Types of Symbols

Indicates that “Warning” or “Caution” must be exercised. Inside this triangle, a con­crete and practical i mage provided as a war ni ng or caution message is depicted.

Indicates a prohibited action or procedure. Inside or near this circle, a concrete and
practical image of the activity to be avoided is depicted.

Indicates a n i mp or t a nt ac tion or pro ced u re wh ich must be pe r forme d or ca rried out
without fail. Failure to follow the instructions herein can lead to malfu nction or
damage to the pump.

Safety instruction

WARNING

● Access limitation

The magnet drive pump has a pair of strong magnets (the magnet capsule

unit and drive magnet). The strong magnet field could adversely affect the

persons who are assisted by electronic devices such as the pacemaker.

● Power OFF

Be sure to turn off power before starting maintenance/repair work. Make

sure no one turns on power while working on the pump, otherwise it may

result in a serious accident. If your work field is noisy or dark, let other peo-

ple know about the situation by displaying a notice such as "POWER OFF

(Maintenance)" near a power switch.

● Wear protective clothing

Always wear protective clothing such as eye protection and protective

gloves during pipework or dismantlement of the pump.

● Lifting pump

When lifting the pump, apply a chain or belts to the eye bolts to keep the

pump horizontal.

Prohibited

Tur ning of f po we r

Wear protective

gear

● Do not remodel pump

Do not remodel the pump. We are not responsible for any personal injury or

property damage due to modification.

● When handling dangerous liquid

For the transfer of the harmful liquid as mentioned below, be sure to con-

duct daily inspection and maintenance for the prevention of liquid/gas leak-

age.

1. Explosive or flammable liquid

2. Corrosive chemicals

3. Harmful liquid or gas

● Keep good ventilation

Poisoning may result when handling a toxic or odorous liquid. Install an air

fan in order to reduce the possibility of health damage.

No Remodeling

Safety instruction

CAUTION

● Attention to magnetic force

Strong magnets are used in this pump. Personal injury may be caused

from the strong magnetic force. Follow the procedure on "Disassembly &

Assembly" when conducting maintenance work.

● Do not run pump dry

Running the pump without liquid, friction heat damages the inside of pump.

Dry running takes place when starting the pump with a closed suction line.

● A qualified operator only

The pump must be handled or operated by a qualified person with a full

understanding of the pump.

● Specified application only

The use of the pump in any application other than those clearly specified

may result in failure or damage.

● Take countermeasures against static electricity

When low electric conductivity liquids such as ultra-pure water and fluor

TM

inactive liquid (e.g. Fluorinert

ated in the pump and may cause static discharge.

● Conduct degassing before operation

Always prime the pump and remove air before operation. Note that hydro-

gen peroxide and sodium hypochlorite easily generate gas and degassing is

) are handled, static electricity may be gener-

Prohibited

Prohibited

needed before every operation. Otherwise, sliding parts may be damaged.

● Countermeasure against efflux

Take protective measures against an accidental chemical overflow results

from pump or piping breakage. Do not soak chemicals into the ground direc-

tory.

● Disposal of the used pump

Dispose of a used pump in accordance with local laws and regulations

(Consult a licensed industrial waste products disposing company.).

1. Unpacking & Inspection

Outline

On unpacking the product, check the following

points. If you find any problems, contact your
nearest distributor.

1. Check the information on nameplate (model

code, flow rate, discharge pressure and voltage)

to see if the product is delivered as per order.

2. Check for transit damage, deformation, and loose

bolts.

Pump unit

Not capable of self-priming. Prime the pump
via inlet or outlet before operation.

Inlet

Drain port

Do not flow chemicals directly
onto the ground. Always drain a
liquid into a suitable container.
Follow an applicable local regu­lation at disposal of liquid.

Motor nameplate

Observe the power voltage specified on the
nameplate.
( Follow an applicable local power regulation.)

Outlet

Motor (Drive unit)

The motor power is
transmitted to the
pump.

Foot

Be sure to fix the
pump.

Pump label

Observe the specifica­tion on the pump label.

CAUTION

Do not wipe labels or the pump body with a solvent.

Slurry

Generally the pump can not send slurry except the KK type (SiC bearing and SiC spindle).

The KK type can handle slurry up to 5% (concentration), 50μm (particle size) and 80Hs (hardness).

Contact us for details.

Performance change

Shaft power, discharge capacity and pump head vary with specific gravity and viscosity. The pump is

designed for a specified liquid. Contact us before changing liquid specification.

Temperature change

Note that viscosity, vapour pressure or corrosiveness changes with liquid temperature. The change is

shown in performance such as flow rate while the pump itself is not affected.

The maximum liquid viscosity for the FF type

1 mPa•S (cP) or more
