● Turn off the power.

Risk of electrical shock. Dismantling/
assembling the pump unit without turn­ing off the power may cause an electrical
shock. Before engaging in any maintenance
or inspection 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
specified 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.

WARNING

CAUTION

● 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 a protective measure against the acci­dental efflux caused by pump or pipe break­age.

● Damaged pumps.

Do not use any damaged pump. Using a
damaged pump may lead to an electric leak
or shock.

CAUTION CAUTION

● Do not place the pump close to water.

The pump is not dust-/water-proof construc­tion. The use of the pump in a humid place
or a place where the pump can get wet may
result in electrical shock or short-circuit.

● Do not damage the power cable.

Risk of fire or electrical shock. Do not
scratch, modify, or pull the power cable.
The cable can also be damaged when it is
heated or loaded with a heavy thing.

● Do not cover the motor during operation.
Or heats builds up and fire or mechanical
failure may result.

● Earthing
Risk of electrical shock. Always earth the pump.

● Install an earth leakage breaker.
An electrical failure of the pump may ad­versely 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 in the fol­lowing places where...

1. Ambient temperature exceeds 40°C or
falls below 0°C.

2. Under a flammable/corrosive atmos­phere.

● Do not drain a harmful chemical liquid

directly on the ground or the floor.

Use a container.

● 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. Fluorinert

TM

) are handled, the static
electricity may generate in the pump and
may cause static discharge. Take counter­measures to remove the static electricity.

Outline

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 voltage to see that the prod­uct is delivered as per order.

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

2. Operating principle

The MD-F is a magnetic drive centrifugal pump.
The magnetic force of the motor drives the impeller mag­net and 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 viscosity is up to 30mPa•s (at SG 1.0).

d. Allowable liquid temperature is 0-80°C.

* Note that the liquid temperature is based on pumping clean

water and it changes with liquid property and operating con­ditions.

* The pump stops when the motor temperature becomes

extremely high due to ambient or liquid temperature rise or
overload operation. The pump resumes operation after tem­perature falls to a normal.

* For the IEC motor, consult your nearest distributor.

CAUTION

● If pump stops frequently, turn off power and check for

impeller damage or clogging. See “Troubleshooting” on
page 17.

● Do not dismantle the motor. Contact us for inspection.
