Safety Instructions

Prohibited

No modification

No dismantlement

Caution

Wear protectors

WARNING

● Turn off power.

Risk of electrical shock. Dismantling/assem-

bling the pump unit without turning off power

may cause an electrical shock. Before

engaging in any maintenance or inspec-

tion work, be sure to turn off the pump and

related devices.

● Terminate operation.

On sensing any abnormality, stop operation

immediately and inspect/solve problems.

● For specified application only

The use of the pump in any application other

than those clearly specified may result in

injury or damage. Use the pump in a speci-

fied condition.

● No dismantlement/modification

Do not dismantle/modify the pump. We are

not responsible for any accidents or damage

due to modification.

● Wear protective clothing.

Always wear protective clothing such as

safety goggles and protective gloves during

pipework or dismantlement.

● Restriction on operator

The pump should be handled by a qualified

person with a full understanding.

● Specified power only

Do not apply any power other than the

specified one on the nameplate. Otherwise

damage or fire may result.

● Do not wet the pump.

If a liquid spills over electric parts or wires, a

fire or electrical shock may result. Install the

pump in a place free from liquid spillage.

● Ventilation

Poisoning may result when handling a toxic

or odorous liquid. Keep good ventilation in a

work area.

● Countermeasure against efflux

Take protective measures against the acci-

dental efflux caused by pump or pipe break-

age.

● Damaged pumps

Do not use any damaged pump. Using a

damaged pump may lead to an electric leak

or shock.

Safety Instructions

CAUTION CAUTION

Prohibited

● Do not place the pump close to water.

The pump is not dust-/water-proof construc-

tion. The use of the pump in a humid place

or a place where the pump can get wet may

result in an electrical shock or short-circuit.

● Do not run pump dry.

If the pump runs without a liquid, the pump

is damaged by friction heat.

● Do not damage a power cable.

Risk of fire or electrical shock. Do not

scratch, modify, or pull a power cable. The

cable can also be damaged when it is heat-

ed or loaded with a heavy thing.

● Earthing

Risk of electrical shock. Always earth the pump.

●Do not pressurize the pump over the

maximum discharge pressure.

A leak may result from the sealing surface

of O ring, or the pump fails at worst.

●Install an earth leakage breaker.

An electrical failure of the pump may ad-

versely affect related devices. Purchase and

install an earth leakage breaker separately.

● Power cable is not replaceable.

Do not use any damaged power cable for

the prevention of a fire or electrical shock.

The cable is not replaceable, so that the

whole pump unit needs to be replaced when

the cable is damaged.

● Limited operating site and storage

Do not install or store the pump:

1. Where ambient temperature can exceed

40°C or falls below 0°C.

Under a flammable/corrosive atmosphere.

3. Under direct sunlight or rainwater

●Disposal of the used pump

Dispose of any used or damaged pump

in accordance with relevant regulations.

Consult a licensed industrial waste products

disposing company.

● Static electricity

When low electric conductivity liquids such

as ultra-pure water and fluor inactive liquid

(e.g. FluorinertTM) are handled, static elec-

tricity may generate in the pump and may

cause static discharge. Take countermeas-

ures to remove static electricity.

● Fasten the front casing tight

Liquid may leak if front casing xing screws

are loose. Tighten the screws before initial

operation or at intervals.

Before use, check the specification, limitation and hazardous nature

of the pump.

1. Unpacking & Inspection

On unpacking the product, check the following points. If you find

any problems, contact your nearest distributor.

1. Check the information on the

nameplate such as model, discharge

capacity, discharge head and volt-

age to see that the product is deliv-

ered as per order.

2. Check for transit damage, deformation, and loose bolts.

2. Operating principle

The MD-F is a compact magnetic drive centrifugal pump with

fluoroplastic and fine ceramic wet ends and is capable of handling

a strong acid and alkali.

The magnetic force between drive and driven magnets rotates the

impeller in the pump chamber, where a liquid is transferred from

the inlet to outlet.

NOTE:

a. Performance data is based on pumping of clear water at ambient

temperature.

b. The maximum flow is obtained at zero discharge head, and the

maximum head is obtained at the maximum pressure.

c. The maximum specific gravity is obtained at or near the maximum

flow. Note that the limitation varies with a duty point, ambient/

liquid temperature or liquid viscosity.

d. The maximum viscosity at SG.1.0 is up to 30mPa•s for all the models.

e. Allowable liquid temperature range is 0-80°C.

*Note that the liquid temperature range is based on pumping clean

water and it changes with liquid property and operating condi-

tions. Frozen liquid can not be transferred.

f. All the single-phase motors used for the MD-55F/-100F series are

capacitor-run induction motor.

g. See the specification label for information other than that articu-

lated above.
