ƔAccess 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.
ƔTurn off power before work
Be sure to turn off the power before starting 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.
ƔWear protective clothing
Always wear protective clothing such as eye protection and protective
gloves during pipework or dismantlement of the pump.
ƔDo not remodel the pump
A remodelled pump will not be warranted. Also, we are not responsible for
personal injury or property damage due to modification.
ƔWhen 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.

Safety instructions
ƔAttention to magnetic force
A pair of strong magnets is mounted in the pump and its magnetic force may affect
magnetic disks/cards or wrist watches. Do not bring them close to the pump.
ƔRestriction on pump operator
The pump must be handled or operated by a qualified person with a full
understanding of the pump.
ƔSpecified application only
Use of the pump in any application other than those clearly specified may
result in personal injury or property damage.
Ɣ6SHFL¿HGSRZHURQO\
Do not apply any voltage other than the specified one on the motor name-
plate. Otherwise, damage or fire may result.
ƔVentilation
Poisoning may result when handling a harmful liquid. Keep good ventilation
in a work area.
ƔCountermeasure against efflux
Take protective measures against accidental chemical efflux and splash at
pump or piping breakage. Do not allow an outflow to directly soak into the
ground.
ƔDo not run pump dry (Operation without liquid)
Friction heart builds up during dry running operation and damages internal
parts. If the pump is operated with a suction side valve closed or without
priming, the pump runs dry.
ƔDo not bring the pump close to a flammable substance
Keep the pump away from a flammable substance for the prevention of fire.
ƔUnpacking
Before unpacking, check the package is not put upside down. Take care not
to be scratched by a nail or a piece of wood at unpackage.
Ɣ
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. Rope or chain the motor to lift up the pump horizontally.

ƔDo not stand on the pump
Do not use the pump as a platform. Injury or damage may result when the
pump turns over.
ƔDo not touch the pump or a pipe
Hot surface temperature. Do not touch the pump or a pipe with bare hands dur-
ing or right after hot liquid transfer. Take preventative measures against burn.
ƔEarthing
Risk of electrical shock. Do not run the pump without earthing. Secure
earth protection to reduce the risk.
ƔInstall 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.
ƔLimitations on working and storage areas
Do not install or store the pump in the following places:
1. Where ambient temperature exceeds 40°C or falls below 0°C.
2. Where ambient humidity exceeds 85%RH or falls below 35%RH.
3.
Underaflammable/explosiveatmosphereorinadustyplace(Exceptexplosion-prooftype).
4. Where the pump is exposed to wind and rain (Except outdoor-use type).
5. Where the pump is subject to vibration.
6. Under a corrosive atmosphere such as chlorine gas.
ƔForeign 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.
ƔStatic electricity
When low electric conductivity liquids such as ultra-pure water and fluor
inactive liquid (e.g. FluorinertTM) are handled, static electricity may gener-
ate in the pump and may cause static discharge. Take countermeasures to
remove static electricity.
ƔPump disposal
Dispose of any used or damaged pump in accordance with local laws and
regulations as an incombustible (Consult a licensed industrial waste prod-
ucts disposing company.).

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 various applications.
