Safety instructions
WARNING
Turning off power
Prohibited
Wear protective
gear
No Remodeling
●Turn off power before work
Be sure to turn off power to stop the pump and related devices before work.
Make sure no one turns on power by mistake while working on the pump,
otherwise it may result in a serious accident. If your working area is noisy or
dark, let other people 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.
●Use strong ropes (chains) for lifting up the pump
Serious injury may result if lifting ropes (chains) break. Check lifting ropes
(chains) are strong enough before use. Observe the maximum weight.
●Use eye bolts
Chain the pump via eye bolts to lift it up. Otherwise the pump may acciden-
tally fall down, resulting in serious injury.
●
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.
●Do 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.
●When handling dangerous liquid
For handling harmful liquids as mentioned below, be sure to conduct daily
inspection and maintenance for the prevention of liquid leakage. Otherwise
personal injury, explosion or fire may result.
1. Explosive or flammable liquid
2. Corrosive or stimulus toxic liquid
3. Health hazardous liquid

●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 personal injury or property damage.
●For a specied power only
Do not apply any voltage other than the specified one on the motor name-
plate. Otherwise, damage or fire may result.
●Ventilation
Poisoning may result when handling a harmful liquid. Keep good ventilation in
a work area.
●Countermeasure 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. Observe applicable codes or regulations for waste chemical disposal.
●Do not run pump dry
Do not run pump dry (Operation without liquid). Friction heart builds up dur-
ing 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.
●Do not bring the pump close to a flammable substance
Keep the pump away from a flammable substance for the prevention of fire.
●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 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.

●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 working and storage areas
Do not install or store the pump in the following places where...
1. Ambient temperature exceeds 40 ºC or falls below 0 ºC.
2. Under a flammable/explosive atmosphere (Except explosion-proof type).
3. Under wind & rain or in a dusty/humid place (Except outdoor-use type).
4. The pump is subject to vibration.
5. Under a corrosive atmosphere such as chlorine gas.
●Starting
The pump doesn't have an ON-OFF switch. The pump starts as a power
cable is plugged in.
●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.).
●Static electricity
When low electric conductivity liquids such as ultra-pure water and fluor inac-
tive liquid (e.g. FluorinertTM) are handled, static electricity may generate in
the pump and may cause static discharge. Take countermeasures to remove
static electricity.

1. Unpacking & Inspection
Outline
On unpacking the product, check the following points.
If you find any problems, contact your nearest dis-
tributor.
1. Check the information on nameplate (model code,
flow rate, head and voltage) to see if the product is
delivered as per order.
2. Check for transit damage, deformation, and loose
bolts.

Outlet
2. Product outline
The MX-F is a magnetic drive centrifugal pump with fluoroplastic and fine ceramic wet ends and is capable of
handling a strong acid and alkali.
■ Principle of operation
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.
