1. Before Use
For reliable pump performance to suit your application purposes, full safety measures should be taken for
the pump unit and the entire system. The following information, including the points to be observed in the
handling of the pump, deals with the measures to ensure the safe operation of the system. Please read
the description carefully.
To operate this pump, a 5-port solenoid valve and a controller (AC-1 type, FD type, SC type or FDC-1
type) are required.
In addition, to enhance system safely, a quick exhaust valve must be installed.

Points to be Observed
Description
1
™
Pump stroke speed:
Do not run pump exceeding the max.
stroke speed which is shown on the
item 4. Specifications on page 8.
¡
If many air bubbles are sucked through pump suction port, pump
is put into state of air locked operation and stroke rate will rise to
abnormal levels. Safety measure should be taken so that pump
does not run at speeds above max. stroke speed. With FD, SC or
FDC-1 controller, the upper limit of stroke speed can be set.
2
™
Supply air pressure must be
maintained within specified
pressure range.
¡
In view of pressure resistance of filter at medium temperature,
provide air under as low pressure as possible, for protection of
bellows & to ensure safety.
¡
Any fluctuation in pressure of supplied air causes change in
discharge. Attach reducing valve to stabilize pressure.
4
™
Prohibited liquids
Caution
Following liquids must not be used.
• Liquids that are easily crystallized
• Liquids containing slurry
• Low conductivity carbon hydrate
liquid
¡
Service life of valve & bellows is shortened with use of liquid that
is easily crystallized or contains slurry. Use of such liquids is not
recommended.
¡
If solvent naphtha is used, electrostatic destruction may be
generated between fluororesin & liquid, finally producing
pinholes.

Liquid temp. range
¡
Temp. of pumped liquid must be within the range of 5-180 deg.C.
