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.

CAUTION

CAUTIONCAUTION

•Use a flexible hose to absorb pump vibration, and ground the hose.

•Make sure that there will be no external force on any connection part of the pump.
Be especially careful not to have the pump support part of the weight of the hose and the piping.

•Use a sturdy hose that will not collapse under the strong suction of the pump. Also, make sure
the hose is of more than sufficient pressure rating.

•Use a hose of a diameter the same as or larger than the pump's ports. If you use a hose of
smaller diameter, the pump's performance will be adversely affected, and it may even malfunction.

•When pumping a fluid that contains slurry, verify that the particle size is below the
slurry limitation (after p.30, 10.1 Main specifications).

If it exceeds the limitation of slurries indicated in the main specifications, attach a strainer to
the pump to stop larger particles. Otherwise, such particles may cause a malfunction.

•If, depending upon the place of pump installation, the
volume of the pumped fluid changes drastically, install a
relief valve on the discharge side, and bring the pressure
down below the maximum permissible value. If, owing to
a change in the volume of fluid, the pressure inside the
pump exceeds the maximum permissible pressure, it
may cause damage.

•Keep a vessel below the relief valve to catch any
drain off.

Fig. 4.2

•When testing piping for leakage, do NOT apply pressure to the pump's inlet and outlet sides with
compressed air from outside. It may cause abnormal breakage to the diaphragm or the switching
portion. When testing the piping, either install a valve between the pump's suction inlet and the
discharge outlet and piping, or disconnect the pump from the piping and install plugs so that there
will be no pressure from outside.

•In our product inspection, clean water (pure water for the DP-F series) is used. To prevent mixture
of dirty water into the fluid to be pumped, clean the inside of the pump before finishing installation
work.

•When installing a standby pump or two pumps in parallel, be sure to provide a valve on each of

the IN and OUT sides and perform pump switching by using the liquid material valve. If the
valve of the stop-side pump is open, the diaphragm will be inverted by the discharge pressure of
the operating-side pump, resulting in damage in an early stage.

•Be sure to sufficiently ground the piping and peripheral equipment.

Note:

Note:

Note: Note:

•So that sufficient air can be supplied to meet the needs of the pump, the diameter of the piping should be the
same as the diameter of the supply port of the pump. Also choose peripheral equipment with sufficient airflow

to meet the requirement of air consumption of the pump. Also must be considered usage and stability of air

pressure. Also must be installed it nearest position of pump unit.

•If you use a solenoid valve as the air valve, be sure it is a three-way valve.
When the valve is closed, the internal compressed air of the pump will be released, and this will switch
the spool to its normal position.

•Use of a coupler for the connection part of each hose will make operation and maintenance easier.

•In case of intermitted operation, lubrication is not required during operation. However when pump is
operating by dry air and in case of continuous operation and/or transferring high temperature liquid
(exceeded 70˚C ), lubrication must be required.

Must be used turbine oil none addition class 1 turbine oil (equivalent ISO VG 32 grade) for lubricants.
Adjust lubricator to supply minimum amount of oil to pump unit.

Note: DP-F series are not required lubrication even using dry air.

•Depending upon the viscosity and specific gravity of the fluid, the suction stroke and
other conditions, the permissible suction flow speed of fluid into the pump will vary
however, if the pump speed (flow speed of fluid) increases greatly, cavitations will occur,
and this not only will reduce pump performance, but it may cause a malfunction. Adjust
the supply air pressure as well as the flow in order to prevent cavitations.

•There is no problem in shutting down the pump with the flow valve closed while air is being
supplied; however, if this condition continues for many hours while there is nobody watching the
pump, it may continue running when there is a leak from the pump or piping, and fluid may
continue flowing out of the position of leakage. Upon finishing your work, release the internal
pressure from the pump and close the air valve (see 5.4 Releasing the pressure).

•When the pump is shut down while pumping slurry, particulate matter contained in the slurry
will be deposited and get stuck inside the out chamber. If the pump is started again as-is,
the diaphragm may be damaged or the center disk may be overloaded, and this may cause
damage such as bending of the center rod. After finishing your work, purge the remaining fluid
from the pump (see 6. Method of cleaning on p.27).
