·Operating caution
Before using this product
WARNING
• 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.
• Pressure Ratings are dependent on pump material and liquid temperature variations.
Please see “Temperature Pressure Curve” in the [10.1 Main specification] and check for the
allowable working pressure at the specific temperature of the liquid being pumped.
Air pressure and discharge pressure must not exceed the allowable working pressure.
If air pressure and discharge pressure exceed the allowable working pressure, it may cause
liquid leaks, damaged pump casings or diaphragms and could cause a 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 droppage, 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 fluids may cause serious injury or even death if accidentally inhaled or consumed or if
they come into 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. Also when pump has positive suction head, liquid will be forced out from exhaust port
due to positive inlet pressure. Make sure to provide protective measures in consideration of
possible leakage of fluid (see NOTE: Arranging outside exhaust on P.16). For example using
a hose and pit etc., also be sure you are using a model with appropriate corrosion resistance
for the fluid to be pumped.
WARNING:
CAUTION :

WARNING
• When installing this product, be sure to connect a ground wire from the specified position of
this product. 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 a model with an aluminum or stainless-steel casing.
*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 its piping.
*If there are flammable gases in the air while the pump is operating, do NOT switch electric
appliance on and off.
*Do NOT operate a gasoline engine at the work site.
*Restrict smoking at the work site.
• 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 torque are
mentioned in maintenance manual.

WARNING
• 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.
Make the warning symbols in
[13.Warning symbols], 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.
• 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
• 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].)
• 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 the pump remains unused for a long period of time, or you have misgivings about running
the pump, please consult with the dealer where you purchased it or our Sales office.

3. Installation
3.1 Method of transport
• When lifting the pump using a chain hoist or crane before transporting it, be sure to lift it by the
specified lift point (see [1. Names of parts and materials]).
WARNING
• Be careful that nobody will pass under the pump when you lift it. It would be very dangerous
if the pump should fall.
CAUTION
• See [10.1 Main specifications]. Remember that the pump is heavy, so extreme care must be
taken when lifting it.
• When moving the pump with a forklift or truck, make sure that the pump will not fall. If it
does, it may be damaged and/or cause bodily injury.
• NEVER try to move the pump by pulling the hose connected to the pump. The hose or the
pump may be damaged.
3.2 Installing the pump
1) Decide where the pump should be installed and secure
a suitable space (see Fig. 3.1 A to D).
NOTE:
• It should be installed horizontally.
• Try to keep the suction lift as short as possible.
To protect diaphragm from abnormal breakage, inlet pressure must be
kept below the following values:
*PTFE diaphragm :0.02 MPa (height 2 m) During operation
:0.05 MPa (height 5 m) Not in operation
*Other diaphragms : 0.1 MPa (height 10 m)
(Condition with fresh water under ambient temperature)
• Remember to provide sufficient space around the pump for
maintenance.
• The direction of the fluid intake port and the discharge port can be
switched opposite from each other.
(For switching, see the maintenance manual.)
• In the event diaphragm failure the exhaust from pump may contain
some sludge.
When operating the pump where it would have an impact on the
environment, the exhaust should be directed to a place where there
will be no environmental impact.
2) Remove the pump from the package and
install it in the designated location.
3) When fixing the pump in place, use the
cushions on the pump base, and secure the
pump by tightening the tied-down bolts a
little at a time.
Fig.3.1
16
CAUTION
• Even if you do not use the cushions to secure the pump in place, mount it in such 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 corrosion resistance of each component of the pump, and do NOT expose the
pump to any fluid for which it does not have proper corrosion resistance.
*Exhaust should directed outside, not into the fluid in which 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 can reach all of the valves without submerging your hand.
• When operating the pump, operation noise may be generated, depending upon conditions of
use (kind of fluid being pumped, supply air pressure and discharge pressure).
If any regulatory rules apply, provide appropriate acoustic measures. (For the noise level of
this product, see [10.1 Main specifications].)
• When pumping a hazardous fluid (hot, flammable, strong acid, etc.), provide protective
measures (installation of a pit or sensors, etc.) in consideration of possible leakage of fluid,
and post warning signs at necessary places. For details, see the applicable operating caution
on P.2 and P.4.
WARNING
• If using the pump with a flammable fluid or in a flammable environment, read the applicable
operating caution on P.3.
NOTE: Arranging outside exhaust
• Remove the silencer.
• Connect a hose with a ground wire to the pump's
exhaust port, and attach the silencer 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,
consult your dealer or our regional office.)
• Have a pit, a protection box, etc. at the end of the hose.
WARNING
• Be sure to have a pit, a protection box, etc. at the end of the hose in preparation for the flow
of fluid in case of damage to a diaphragm. For details, see the applicable operating caution
on P.2.
• Pump exhaust should be directed to a safe place, away from people, animals and food.
NOTE: Solenoid Operation
When air line operation is to be controlled by a solenoid valve, a three way type is recommended.
A three-way solenoid valve allows any trapped air to bleed off, in turn improving pump performance.
Fig.3.2
17
3.3 Connecting the ground wire
a) When installing the pump, be sure to connect the ground wire at the specified position. For the
specified position for connecting the ground wire, see [1. Names of parts and materials].
b) Also connect ground wires to peripheral equipment and piping.
c) Use 2.0mm2 minimum ground wire.
WARNING
• Be sure to connect ground wires to the connected piping and any other connected equipment.
For details, see the applicable operating caution on P.3.
When the pump is operated without a ground wire or otherwise not properly grounded,
friction between parts and abrasion caused by some fluids flowing 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 or the surrounding fixtures), it may be a
cause of fire or electric shock.

4. Connection
4.1 Connecting fluid piping
1) Connect a flow valve and a drain valve to the fluid discharge port of the pump.
2) Connect a valve for maintenance to the fluid suction intake port of the pump.
3) Connect a hose to the valve on the suction-port side and the valve of the discharge-port side of the
pump.
4) Connect a hose on the suction-side intake and the discharge-port side to the respective vessels.
CAUTION
• 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 (see [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.
• 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 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 from, 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.
Fig.4.2
Fig.4.1

4.2 Connecting air piping
WARNING
• Before starting work, make sure that the air compressor is shut off.
1) Connect an air valve, air filter, regulator and if necessary lubricator (hereinafter called the "peripheral
equipment") to hose which connected to compressor. Refer for detail information.
2) Install these peripheral items supported by brackets, etc., near the pump.
3) Connect the hose from the peripheral equipment to the air valve of the pump's supply port.
CAUTION
• 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.
• The piping and the peripheral equipment may become clogged with sludge. Clean the inside
of the piping for 10 to 20 seconds before connecting it to the pump.
• Be sure to sufficiently ground the piping and peripheral equipment.
NOTE:
• Air piping size should be equal to the inlet port of the pump to supply enough air to run the pump. The air
compressor should be able to provide adequate air flow to the pump. Attach the compressor as close as
possible to the pump, considering operability and stability of air pressure.
• 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.
• If you use the pump intermittently the pump will not require lubrication. However lubrication is
recommended if running the pump continuously for long periods or using very dry air or at high
temperatures. This will guarantee the life of the pumps seals.
*High temperature operation: When transferring liquid whose temperature exceeds 70°C
*Continuous operation: When the pump operates continuously for longer than 1 hour and is stopped for less
than 15 minutes.
*Lubrication: Use only turbine oil Class 1 grade oil (equivalent to ISO VG 32), under the following
conditions; Oil concentration at 50mg/m³, Absolute pressure at 0.1MPa. Maximum temperature of 20°C
and Humidity at 65%.
Fig.4.3

5. Operation
5.1 Method of operation
CAUTION
• Before starting the pump, make sure that all piping is properly connected.
• Also, before starting the pump, make sure that all the bolts are securely tightened.
(Refer to the maintenance manual for the bolts that a regulation torque are explained.)
• Make sure that the air valve, regulator and the drain valve on the discharge side are closed.
Also, make sure that the valve on the suction side is opened.
1) Start the air compressor.
2) Open the air valve in front of each piece of peripheral equipment, and adjust the supply air pressure
with a regulator to within the permissible range (see [10.1 Main specifications]).
3) Open the flow valve on the discharge side.
4) Press the RESET button(NDP-H40~NDP-H80 is excluded), and then slowly open the air valve of the
pump.
5) First, verify that fluid is flowing inside the piping and is being pumped to the discharge side, and then
fully open the air valve.
6) Again adjust the supply air pressure with a regulator to within the permissible range (see [10.1 Main
specifications]).
CAUTION
• Do NOT open the air valve suddenly.
• In case of use lubricator, must be used turbine oil none addition class 1 turbine oil
(equivalent ISO VG32 grade) for lubricants. Do not apply lubricants more than required and
also do not use any other lubricants, which designated on this instruction manual. This may
cause of pump problem and there is danger of serious bodily damage.
5.2 Flow adjustment
• Adjust the flow valve on the discharge side. For the relationship among the flow, supply air pressure
and discharge pressure, see [10.3 Performance curve].
CAUTION
• As you start closing the flow valve, the supply air pressure may rise. Make sure that the
pressure is kept within the normal operating range (see [10.1 Main specifications]).
• 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, cavitation 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 cavitation.
• If fluid is not discharged after you start the pump, or if you hear an abnormal noise or notice
any irregularity, shut down the pump immediately (see [8. Troubleshooting]).
21
5.3 Shutdown
• Close the air valve of the pump and shut off the supply air.
CAUTION
• 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]).
5.4 Releasing the pressure
1) Make sure that the air valve of the pump is closed.
2) Shut down the air compressor or close the valve on the air-supply side of the peripheral equipment.
3) Close the flow valve on the discharge side, start slowly opening the drain valve, and discharge the fluid
under pressure.
4) Open the air valve of the pump, start running the pump, and discharge the remaining air.
5) After making sure that the pump has been shut down and the pressure has been released, fully open
the regulator, and close the air valve and drain valve of the pump.
CAUTION
• Keep a vessel below the relief valve to catch any drain off.
• Fluid under pressure will gush out as soon as you open the valve, so be careful.
• If the pump will be unused for a prolonged period, purge and clean the pump (see the
Operating caution on P.3).
22
6. Method of cleaning
WARNING
•Before starting operation, make sure that compressed air is not supplied to the pump.
•Before starting operation, make sure that the pump is not pressurized.
1) Remove the hose from the suction side of the pump.
2) Close the flow valve on the discharge side, open the drain valve, and then operate a pump by starting
air pressure for a while to discharge any fluid remaining inside the pump as much as possible.
3) Remove the hose from the discharge side, and attach different hoses to the suction side and the
discharge side for cleaning.
4) Be ready with a vessel with cleaning solution, select cleaning solution appropriate for the type of fluid
pumped, and then connect the suction-side and the discharge-side hoses of the pump.
5) Operate a pump by starting air pressure slowly, and let the cleaning solution circulate for sufficient
cleaning.
6) Finally, flush with clean water.
7) Remove the hose from the suction side of the pump, run the pump for a while and purge the pump of
remaining fluid as much as possible.
CAUTION
• Be careful when removing piping. Fluid will gush out.
• After cleaning with clean water, turn the pump upside-down to drain out the water.
23
7. Daily check
• Before starting pump operation, be sure to conduct the following check every day. If any irregularity is
found, do NOT start running the pump until the cause of the irregularity has been found and corrective
measures have been taken.
a) Verify the drain flow through the air filter.
b) In case using a lubricator, verify the quantity of lubricating oil.
c) Make sure that there is no leakage of fluid from any connection part or the pump.
d) Make sure that there are no cracks in the pump casing or piping.
e) Check the tightness of every bolt of the pump.
(Refer to “maintenance manual” about the retighten of “Tie rod”)
f) Make sure that the connection parts of the piping and peripheral equipment are not loose.
g) Make sure that the time has not elapsed for replacing any parts of the pump that are to be replaced at
regular intervals. For details, see the maintenance manual.
