Safety instructions
WARNING
● Turn off power before work
Be sure to turn off all the related power supplies prior to any inspection/
maintenance and installation works. Working on the pump with power ON,
any rotating part may catch the hand, finger, hair, or clothes, and it may
result in serious injury. 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.
● Stop operation
If you notice any abnormal or dangerous conditions, suspend operation im-
mediately and inspect/solve problems.
● Do not use the pump in any condition other than its intended purpose
The use of the pump in any conditions other than those clearly specied
may result in failure or injury. Use this product in specied conditions only.
● Do not modify the pump
Alterations to the pump carries a high degree of risk. It is not the manufac-
turer’s responsibility for any failure or injury resulting from alterations to the
pump.
● Wear protective clothing
Always wear protective clothing such as an eye protection, chemical re-
sistant gloves, a mask and a face shield during disassembly, assembly or
maintenance work. The specic solution will dictate the degree of protec-
tion. Refer to MSDS precautions from the solution supplier.

WARNING
● 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
serious injury.
● 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
● Do not damage a power cable
Do not pull, knot, or crush the power cable. Damage to the power cable
could lead to a re or electrical shock if cut or broken.
● Do not operate the pump in a flammable atmosphere
Do not place explosive or ammable material near the pump.
● Do not catch the finger
Magnetic force of the pump is powerful. Take care not to catch the finger in
the bracket.

CAUTION
● Qualified personnel only
The pump should be handled or operated by qualified personnel with a full
understanding of the pump. Any person not familiar with the product should
not take part in the operation or management of the pump.
● Use specified power only
Do not apply power other than that specied on the nameplate. Otherwise,
failure or re may result. Ensure the pump is properly grounded.
● 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 oper-
ated with a suction side valve closed or without priming, the pump runs dry.
● Ventilation
Fumes or vapours can be hazardous with certain solutions. Ensure proper
ventilation at the operation site.
●Do not install/store the pump:
• In a ammable/explosive/corrosive atmosphere.
• In a dusty/humid environment.
• Where ambient temperature can exceed 0-40°C.
• Under mechanical vibrations.
• In direct sunlight or wind & rain.
●Spill precautions
Ensure protection and containment of solution in the event of plumbing or
pump damage (secondary containment).
● Do not stand on the pump
Do not use the pump as a platform. Injury or damage may result when the
pump turns over.

CAUTION
● Do not touch the pump or pipe with bare hands
Risk of burning. The surface temperature of the pump or pipe rises high
along with liquid temperature in or right after operation.
● Grounding
Risk of electric shock! Always properly ground the pump. Conform to local
electric codes.
● Install a GFCI (earth leakage breaker)
An electrical failure of the pump may adversely affect other devices on the
same line. Purchase and install an earth leakage breaker separately.
● 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.
● Static 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.
●Preventative maintenance
Follow instructions in this manual for replacement of wear parts. Do not
disassemble the pump beyond the extent of the instructions.
●Do not use a damaged pump
Use of a damaged pump could lead to an electric shock or death.
●Disposal of a used pump
Dispose of any used or damaged pump in accordance with local rules
and regulations. If necessary, consult a licensed industrial waste disposal
company.

product is delivered as per order.
2. Check for transit damage, deformation, and loose
bolts.
2. Product outline
The MX is a magnetic drive centrifugal pump capable of handling various liquid.
■ 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.
