● Access limitation
The magnet drive pump has a pair of strong magnets. A strong magnet
field could adversely affect the persons who are assisted by electronic
devices such as the pacemaker.
● Turn off power before work
Be sure to turn off the power before starting a maintenance/repair work.
Make sure no one turns on the power while working on the pump, other-
wise it may result in a serious accident. Let other people know about the
situation by displaying a notice such as "POWER OFF (Maintenance)" near
the power switch.
● Wear protective clothing
Always wear protective clothing such as eye protection and protective
gloves during pipework or dismantlement of the pump.
● Do not remodel the pump
A remodelled pump will not be warranted. Also, we are not responsible for
a personal injury or property damage due to modification.
● When handling harmful liquid
For handling harmful liquids as mentioned below, be sure to conduct daily
inspection & maintenance for the prevention of liquid/gas leakage.
1. Explosive or flammable liquid
2. Corrosive liquid
3. Health hazardous liquid
Pay extra attention. Generated gas can stay in the top of front casing.

● Magnetic force affects magnetic disks/cards and wrist watches
A pair of strong magnets is mounted in the pump and its magnet force may affect
magnetic disks/cards or wrist watches. Do not bring them close to the pump.
● Restriction on pump operator
The pump must be handled or operated by a qualified person with a full
understanding of the pump.
● For a specified application only
Use of the pump in any application other than those clearly specified may
result in a personal injury or property damage.
● For a specifi ed power only
Do not apply any voltage other than the specified voltage on the motor
nameplate. Otherwise, damage or fire may result.
● Ventilation
Poisoning may result when handling a harmful liquid. Keep good ventilation
in your operating site.
● Countermeasure against efflux
Take a protective measurement against accidental chemical efflux and
splash at pump or piping breakage. Also, take an appropriate measurement
to prevent accidental outflow from directly soaking into the ground.
● Do not run pump dry
Do not run pump dry (Operation without liquid). Friction heart in the dry
running damages internal parts. If the pump is operated with a suction side
valve close or without priming, the pump runs dry.
● Do not bring the pump close to a flammable substance
Keep the pump away from a flammable substance for the prevention of fire.
● Unpacking
Before unpacking, check package is not put upside down. Take care not to
be scratched by a nail or a piece of wood at unpacking.

●
Do not lift the pump by gripping any plastic parts (pump unit, flange or base)
The pump can drop unintentionally as a plastic part breaks, resulting in seri-
ous injury. Use rope or chain to the motor to lift the motor horizontally.
● Do not stand on the pump
Do not use the pump as a platform. Injury or damage may result when the
pump turns over.
● Do not touch the pump or pipe
Hot surface temperature. Do not touch the pump or pipe with the bare hand dur-
ing or right after hot liquid transfer. Take a preventative measure against burn.
● Earthing
Risk of electrical shock. Do not run the pump without earthing. Secure
earth protection to reduce the risk.
● Install an earth leakage breaker
Risk of electrical shock. Do not run the pump without a leakage breaker.
Secure a leakage breaker to reduce the risk.
● Limitations on operating site and storage
Do not install or store the pump in the following places where...
1. Ambient temperature is beyond 0-40 ºC.
2. Relative humidity is beyond 35-85%RH.
3. Under a flammable/explosive atmosphere or in a dusty place (Except explosion-proof type).
4. The pump is exposed to wind and rain (Except outdoor-use type).
5. The pump is subject to vibration.
6. Under a corrosive atmosphere such as chlorine gas.
● Foreign matter
When foreign matters enter the pump, turn off power at once and remove
them. Using the pump with foreign matters may result in failure.
● Pump disposal
Any used or damaged pump must be disposed of in accordance with local
laws and regulations as an incombustible (Consult a licensed industrial
waste products disposing company.).

■ Principle of operation
a. Running the pump after priming, liquid and gas
start to move into the pump chamber, where gas-
liquid separation occurs.
b. Once all gas is expelled, normal centrifugal
pump operation is resumed.
c. Sufficient liquid remains in the pump chamber
for subsequent self-priming once the pump is
stopped.
2. Product outline
The SMX-F series pump is a self-priming centrifugal pump of a gas-liquid separation system.
Fluoroplastic and fine ceramic wet ends are capable of handling a wide range of chemicals in vari-
ous applications.
