Introduction

IntroductionIntroduction

Thank you for purchasing a Yamada Diaphragm Pump. This product is a positive-displacement pump that transfers
fluids by movement of diaphragms driven by compressed air through a unique switching mechanism. The casing that
comes in contact with the fluid is made of aluminum, stainless steel, forged iron, and polypropylene or fluorine resin,
depending on the model you have selected according to the type of fluid to be pumped. The diaphragms are made of a
plastic material suitable for the model.

WARNING

WARNING

WARNINGWARNING

•When using compressed gas (hereinafter called "compressed air") to drive this pump, be sure
it is one of the following:
* Compressed air supplied from an air compressor
* Nitrogen (N2) gas
Use of compressed air other than the above may cause air pollution, damage to the pump, or
even an explosion.

•The maximum permissible pressure for the compressed air, and the fluid pumped by one of
these pumps, depending upon the casing material of the model you are using, is as follows:
*Metal casing (aluminum, stainless steel, forged iron): 0.7MPa (7kgf/cm2)
*Plastic casing (polypropylene, fluorine resin): 0.7MPa (7kgf/cm2)
(0.5MPa for the DP-05F until DP-20F) (0.7MPa for the DP-25F/38F)

If the pressure of the compressed air and fluid exceeds the above applicable maximum
permissible pressure specified above, there may be leakage of fluid, damage to the casing,
or even a severe, possibly even fatal, accident.

•When moving this product, make sure that the internal pressure is released.
If the pump is moved while under pressure, any shock imparted by drop page,
etc. may damage the pump or even cause an explosion.

•Hazardous fluids (with strong acid or alkali, flammable or toxic) or gas bubbles generated by such

contact with the eyes or adhere to skin. Therefore, the following precautions are strongly advised.

*Be fully familiar with the properties of the fluid to be pumped and work in strict accordance with

the operating instructions provided by the suppliers of such fluids (such as wearing goggles,
gloves, mask or work clothes).

*When storing a hazardous fluid, strictly comply with the regulatory procedures (such as using

proper containers, storage conditions, etc.).

*Always install the piping and exhaust port of this pump away from human and animal traffic.
When a diaphragm is damaged, fluid will gush out together with air through the exhaust port.
Provide protective measures in consideration of possible leakage of fluid (see Notes: Arranging
outside exhaust on p.20). When you use the hose and pit etc., be sure you are using a model with
appropriate corrosion resistance for the fluid to be pumped.

WARNING

WARNING

WARNINGWARNING

•When installing this product, be sure to connect a ground wire from the specified position of
this product (excluded NDP-5FPT, NDP-10, 15FP□, and DP-F series).

When this product is installed and operated without the ground wire properly connected, friction
between parts, as well as abrasion caused by the flow of some fluids inside the casing, may
generate static electricity. Also, depending on the type of fluid being pumped and the installation
environment (such as gases in the air and type of surrounding fixtures), static electricity could
become a cause of fire or electric shock.

•Improper grounding, poor ventilation, or unshielded fire or spark can create a danger of fire
or explosion. Therefore, the following precautions are strongly advised.

*All peripheral equipment and piping connected to this product should be properly grounded.
*To pump flammable liquids, use an ATEX compliant model.
*Whenever you notice any spark while operating this product, immediately stop its operation,
and do NOT start using it again unless you are sure of the cause and corrective actions have
been taken.
*Depending upon the type of fluid being pumped, bubbles of flammable gas may be generated.

Make sure that ventilation is satisfactory.
*This product itself, its piping and exhaust ports should be kept away from unshielded fire,
spark and other causes of ignition. If a diaphragm is damaged, fluid will gush out together
with air from the exhaust port.
*Do NOT leave gasoline or solvent etc. that contains waste at the work site.
*Machinery and other equipment near the place of installation of this product should be
properly insulated to prevent conduction with each other.
*Do NOT operate heating devices that create 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 switch electric

appliances on and off.
*Do NOT operate a gasoline engine at the work site.
*Restrict smoking at the work site.

•The DP-F series pumps are intended for pumping hazardous fluids such as those that contain
strong acids or organic solvents. If you find any irregularity in this product, do

NOT try to disassemble or service the product yourself. Contact your dealer or our regional office
for service.
If you disassemble or service this product yourself and if further irregularity occurs, it may cause
a great risk, depending upon the kind of fluid to be pumped.

•After you shut down the pump and disconnect 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 connected piping. Therefore, be sure to purge the system of fluid and clean the pump before

prolonged disuse.

If the product is left unused for a prolonged period with fluid remaining in the connected piping as
well as the pump itself, the fluid may expand, depending on the ambient temperature (because of
freezing or heat), which may cause damage to the pump and/or piping and possible leakage of fluid.

•Always use genuine Yamada parts when replacing component parts of this product.
Do NOT attempt to modify the components parts or replace them with other than
genuine Yamada parts.

•Torque of all tightening parts must be inspected before operation.
Designated torques is mentioned in maintenance manual.

WARNING

WARNING

WARNINGWARNING

•When pumping a hazardous fluid (hot, flammable, strong acid, etc.) with this product,
provide protective measures (install a pit, a protection box, sensors, etc.) in consideration of

possible leakage of fluid, and post
warning signs at necessary places.
Copy the warning symbols on p.61,
and attach them to the casing and
piping, etc.

Leakage of fluid may cause fire, air
pollution or a serious accident.
When pumping a hot fluid, the
casing and piping will become hot,
which may burn the skin when
touched.

Fig.0.1

•Before using this product, be sure you are familiar with the precautions regarding the fluid to
be pumped, and verify the corrosion resistance of the parts that will come into contact with the
fluid. NEVER use the product with any fluid against which it does not have sufficient corrosion

resistance or with a fluid that poses a risk of explosion. If you are unsure of the corrosion

resistance, contact your dealer or our regional office.

If you use this product with any fluid against which the parts that will come in contact with the
fluid do not have sufficient corrosion resistance, it may result in damaging the product or leakage
of fluid.

•When working in the vicinity of pumping of fluid with this product, be sure to wear protective
gear (goggles, mask, etc.).

•When using this product, observe the relevant regulatory rules concerning fire prevention, labor
safety standards, etc.

•If you have any questions on the operation of this product (method of connection or installation),
contact your dealer or our regional office.

CAUTION

CAUTION

CAUTIONCAUTION

•When operating this product, it may generate loud operating noise, depending upon the condition

of use (fluid pumped, supply air pressure and discharge pressure).

If regulatory rules apply, provide appropriate acoustic measures where necessary. (For the noise
value of this product, see 10.1 Main specifications after p.30.)

•To drive this product, use supply air with minimum moisture content.

•If a diaphragm of this product is damaged, supply air may mix with the fluid or the fluid may flow
into the main body (air-switching portion). If air supply is inadequate or contaminated, do NOT
operate the pump.

•While operating this product, do NOT cover the intake port by hand.

•If more than two years have elapsed since this product was shipped from the factory, notify your
dealer or our regional office, and do NOT operate it without assurance from the dealer or our
regional office that the pump may be operated safely.
