2. Operating principle
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.
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.
Before use, check the specification, limitation and hazardous nature
of the pump.

2. Installation/ Piping/ Electrical wiring
Stop working upon sensing a danger in work.
2.1 Installation
1. Installation location
Select a convenient place for main-
tenance and inspection. Observe the
allowable room temperature range
of 0 - 40°C and the maximum ambi-
ent humidity of 90%RH.
2. Mounting position
This pump is not capable of self-
priming. Flooded suction applica-
tion is ideal. Try to install the pump
30cm lower than a suction liquid
level.
CAUTION
Air may be introduced into the
pump, wearing out bearings exces-
sively if a liquid level in a supply
tank is too low.
3. Outlet direction
Always direct the outlet upward, or
entrained air can not be expelled.
CAUTION
Do not mount the pump vertically,
directing the pump head upward.
Always use corrosion resistant screws
for anchoring the pump.
4. Pump fixation
Secure the pump by fixing the base.
Do not install the pump vertically.
2.2 Piping
1. In order to minimize the piping
resistance, have piping shortest with
the minimum bends. For the preven-
tion of cavitation, have the suction
piping bore wide as much as possible.
2. The pump can be plumbed via thread
or flange connection. See a specifica-
tion table on page 4 for suitable con-
nection.
Direct the outlet upward
30cm
or
more

3. Install valves on both discharge and
suction lines.
• Suction-side valve:
For easy pump removal and main-
tenance.
• Discharge-side valve:
For adjustment of a flow rate and a
discharge head.
4. Do not allow piping system to weigh
heavily on the plastic inlet or out-
let, otherwise the plastic parts may
deform and result in failure.
5. The MX-F100KV is provided with a
cushioning material in outlet. Remove
it before pipework.
CAUTION
Be careful not to drop the pump onto
the floor. A strong impact may reduce
pump performance.
