WARNING
WARNINGWARNING
WARNING
•When using ompressed gas (hereinafter alled " ompressed air") to drive this pump, be sure
it is one of the following:
* Compressed air supplied from an air ompressor
* Nitrogen (N
2
) gas
Use of ompressed air other than the above may ause air pollution, damage to the pump, or
even an explosion.
•The maximum permissible pressure for the ompressed air, and the fluid pumped by one of
these pumps, depending upon the asing material of the model you are using, is as follows:
*Metal asing (aluminum, stainless steel, forged iron): 0.7MPa (7kgf/ m
2
)
*Plasti asing (polypropylene, fluorine resin): 0.7MPa (7kgf/ m
2
)
(0.5MPa for the DP-05F until DP-20F) (0.7MPa for the DP-25F/38F)
If the pressure of the ompressed air and fluid ex eeds the above appli able maximum
permissible pressure spe ified above, there may be leakage of fluid, damage to the asing,
or even a severe, possibly even fatal, a ident.
•When moving this produ t, make sure that the internal pressure is released.
If the pump is moved while under pressure, any sho k imparted by drop page,
et . may damage the pump or even ause an explosion.
•Hazardous fluids (with strong a id or alkali, flammable or toxi ) or gas bubbles generated by su h
fluids may ause serious injury or even death if a identally inhaled or onsumed or if they ome into
onta t with the eyes or adhere to skin. Therefore, the following pre autions are strongly advised.
*Be fully familiar with the properties of the fluid to be pumped and work in stri t a ordan e with
the operating instru tions provided by the suppliers of su h fluids (su h as wearing goggles,
gloves, mask or work lothes).
*When storing a hazardous fluid, stri tly omply with the regulatory pro edures (su h as using
proper ontainers, storage onditions, et .).
*Always install the piping and exhaust port of this pump away from human and animal traffi .
When a diaphragm is damaged, fluid will gush out together with air through the exhaust port.
Provide prote tive measures in onsideration of possible leakage of fluid (see Notes: Arranging
outside exhaust on p.20). When you use the hose and pit et ., be sure you are using a model with
appropriate orrosion resistan e for the fluid to be pumped.

WARNING
•When installing this produ t, be sure to onne t a ground wire from the spe ified position of
this produ t (ex luded NDP-5FPT, NDP-10, 15FP □ , and DP-F series).
When this produ t is installed and operated without the ground wire properly onne ted, fri tion
between parts, as well as abrasion aused by the flow of some fluids inside the asing, may
generate stati ele tri ity. Also, depending on the type of fluid being pumped and the installation
environment (su h as gases in the air and type of surrounding fixtures), stati ele tri ity ould
be ome a ause of fire or ele tri sho k.
•Improper grounding, poor ventilation, or unshielded fire or spark an reate a danger of fire
or explosion. Therefore, the following pre autions are strongly advised.
*All peripheral equipment and piping onne ted to this produ t should be properly grounded.
*To pump flammable liquids, use an ATEX ompliant model.
*Whenever you noti e any spark while operating this produ t, immediately stop its operation,
and do NOT start using it again unless you are sure of the ause and orre tive a tions have
been taken.
*Depending upon the type of fluid being pumped, bubbles of flammable gas may be generated.
Make sure that ventilation is satisfa tory.
*This produ t itself, its piping and exhaust ports should be kept away from unshielded fire,
spark and other auses of ignition. If a diaphragm is damaged, fluid will gush out together
with air from the exhaust port.
*Do NOT leave gasoline or solvent et . that ontains waste at the work site.
*Ma hinery and other equipment near the pla e of installation of this produ t should be
properly insulated to prevent ondu tion with ea h other.
*Do NOT operate heating devi es that reate flames or have heating filaments anywhere near
the pump or the piping.
*If there are flammable gases in the air while the pump is operating, do NOT swit h ele tri
applian es on and off.
*Do NOT operate a gasoline engine at the work site.
*Restri t smoking at the work site.
•The DP-F series pumps are intended for pumping hazardous fluids su h as those that ontain
strong a ids or organi solvents. If you find any irregularity in this produ t, do
NOT try to disassemble or servi e the produ t yourself. Conta t your dealer or our regional offi e
for servi e.
If you disassemble or servi e this produ t yourself and if further irregularity o urs, it may ause
a great risk, depending upon the kind of fluid to be pumped.
•After you shut down the pump and dis onne t the piping, some fluid may remain inside the pump.
Also, if the pump is left unused for a prolonged period, some fluid may remain inside the pump
and onne ted piping. Therefore, be sure to purge the system of fluid and lean the pump before
prolonged disuse.
If the produ t is left unused for a prolonged period with fluid remaining in the onne ted piping as
well as the pump itself, the fluid may expand, depending on the ambient temperature (be ause of
freezing or heat), whi h may ause damage to the pump and/or piping and possible leakage of fluid.
•Always use genuine Yamada parts when repla ing omponent parts of this produ t.
Do NOT attempt to modify the omponents parts or repla e them with other than
genuine Yamada parts.
•Torque of all tightening parts must be inspe ted before operation.

•When moving the pump with a forklift or tru k, make sure that the pump will not fall. If it does,
it may be damaged and/or ause bodily injury.
•NEVER try to move the pump by pulling the hose onne ted to the pump. The hose or the pump
may be damaged.
3.2 Installing the pump
3.2 Installing the pump 3.2 Installing the pump
3.2 Installing the pump
1) De ide where the pump should be installed and se ure a suitable spa e
(see Fig. 3.1 A to D).
Note:
Note: Note:
Note:
•Try to keep the su tion lift as short as possible.
Prote t diaphragm from abnormal breakage, inlet pressure must be
kept below the following values:
*PTFE diaphragm: 0.02MPa (height 2m) During operation
: 0.05MPa (height 5m) Not in operation
*Other diaphragms: 0.1MPa (height 10m)
(Condition with fresh water under ambient temperature)
•Remember to provide suffi ient spa e around the pump for
maintenan e.
•Can be hanged the dire tion of the fluid intake port and the dis harge
port opposite from ea h other. (For swit hing, see the maintenan e
manual.)
•The exhaust from the pump will ontain some sludge.
When operating the pump where it would have an impa t on the
environment, the exhaust should be dire ted to a pla e where there will
be no environmental impa t.
2) Remove the pump from the pa kage and install it in the designated lo ation.
3) When fixing the pump in pla e, use the
ushions on the pump base, and se ure
pump by tightening the tied - down
bolts a little at a time.

CAUTION
CAUTIONCAUTION
CAUTION
•Even if you do not use the ushions to se ure the pump in pla e, mount it in su h a way
that vibration generated by pump operation will be absorbed.
•If the pump will be submerged during operation, follow the steps below:
*Verify the orrosion resistan e of ea h omponent of the pump, and do NOT expose the
pump to any fluid for whi h it does not have proper orrosion resistan e.
*Exhaust should dire t outside, not into the fluid in whi h the pump is submerged. For
information on how to arrange the exhaust, see Note: Arranging outside exhaust and
Fig. 3.2 below.
*Make sure that you an rea h all of the valves without submerging your hand.
•When operating the pump, operation noise may be generated, depending upon onditions of use
(kind of fluid being pumped, supply air pressure and dis harge pressure).
If any regulatory rules apply, provide appropriate a ousti measures. (For the noise level of this
produ t, see 10.1 Main spe ifi ations on p.26.)
•When pumping a hazardous fluid (hot, flammable, strong a id, et .), provide prote tive measures
(installation of a pit or sensors, et .) in onsideration of possible leakage of fluid, and post warning
signs at ne essary pla es. For details, see the appli able operating aution on p.4,5 and 6.

Notes: Arranging outside exhaust
•Remove the silen er.
•Conne t a hose with a ground wire to the pumps exhaust port, and
atta h the silen er to the tip of the hose. Use a hose of the same
diameter as the exhaust port. (If the hose is longer than 5 meters,
onsult your dealer or our regional offi e.)
•Have a pit, a prote tion box, et . at the end of the hose.
