INSTRUCTION

- Preface
Thank you very much for purchasing Yamada Pump.
The SR-140PWALseries is air operated pump units designed for use with a 20 litre pail. With a combination of a type 140 air
powered pump and an air operated lift, the unit is suitable for transferring/supplying high viscosity materials like grease.
Through pipes and hoses, material can be supplied to various sections of a work site.At each section, you can use material
anytime just by controlling an outlet valve.
The inductor plate provides a tight seal between the plate and a pail, prevents the forming of an air pocket in the suction port,
and helps to pump and transfer material efficiently until a pail gets empty.
There are two types of inductor plates: Flat packing type (F) and Tube packing type (T). You can choose the appropriate one
depending on material and its viscosity.
Furthermore, in the flat packing type, a punch plate is attached on the bottom of the inductor plate to make it possible to use
up material in a pail as much as possible.
The lift has removable caster wheels on the bottom. You can move the whole unit with a pail mounted. By removing these
wheels, the unit can be secured to the floor using anchor bolts.

prefer it, please consult to YAMADA.
[Installation and piping]
- Install an emergency stop valve.
Attach an emergency stop valve to the air piping (somewhere accessible between the air source and unit)
and close this valve in case of emergency.
- Stop operation.
If any abnormality is found during operation, immediately stop the machine. Do not restart until the cause
has been identified and corrected.
- Shut off air supply.
Shut off the air source BEFORE installation and piping.
- Install properly.
Install the unit properly according to the requirements for location and material, pressure resistance, and
size of hoses and other device, avoiding lift operation failure and pipe leakage or breakage.
- Do not plumb directly.
Do not connect the material outlet and piping directly. Attach a flexible tube like a hose to connect the pump
to the piping. The pump, if connected directly to the piping, may cause many problems (e.g., noise caused
by vibration, damage to the piping, operation failure of the lift, and failure of maintenance).
[Handling]
- Do not put your hand or any other part of your body between the inductor plate and a pail.
Be aware that the lift, when operated at 0.5MPa air pressure, will generate about 270kgf (press force). Be
sure to set the lift air regulator normally at 0.4MPa and NEVER exceed the maximum operating pressure of
0.7MPa.
- Do not touch the speed control on the air cylinder of the lift.
The lift speed is maintained at a constant level (factory setting).
- In case of emergency
Close the emergency stop valve.
- Air pressure to the unit
Set the primary air pressure to 1.0MPa or less.
- Air pressure to the pump
Set the pump air regulator to 0.7MPa or less.
[Shutdown and storage]
- When left unused for a long time (an hour or more) or shutdown
In such case, close the air source and open the bleeder valve to release residual pressure inside the pump.
(Close the bleeder valve after the residual air and material is removed.)
If a drum is not mounted, move the lift to the lower limit and put a plastic bag over the inductor plate to
prevent dust.

- Do not put your hand or any other parts of your body between a pail and the inductor plate when
installing a pail. An unexpected body injury may be caused.
- To prevent excessive pressure in a pail, do not push the “AIR” button when the lift control switch is
set to “PRESS”.
- If the “AIR” button is pushed when there is still material in a pail, air bubbles will form in material.
- When the lift stops due to a foreign object caught in the sliding part, be sure to move the lift to the
opposite direction BEFORE removing an object. The lift may suddenly start moving if a foreign
object is removed directly.
3.1 Description of control and valve
（Refer to “Fig. 1 Part names” and “Fig. 2 Names of operation part”）
- Pump Air Regulator
Function : Controlling air pressure for pump operation.
To operate : Clockwise turn will increase pressure. Counterclockwise turn will decrease pressure.
(It can be locked by pushing the knob in.)
Note : The maximum allowable operating pressure of the pump is 0.7MPa. DO NOT exceed this limit.
Remark : Discharge pressure can be calculated by multiplying the air pressure by the pump ratio.
- Air Valve, Pump (ball valve attached to the right side of pump air control)
Function : Starting/Stopping the pump.
To operate : When the lever is parallel to the pipe, the valve is open. If the lever is perpendicular to the pipe,
the valve is closed.
Note : In case of emergency, close the emergency stop valve attached to the air piping instead of this
valve.
- Lift Air Regulator
Function : Controlling air pressure for lift and inductor plate operation.
To operate : Clockwise turn will increase pressure. Counterclockwise turn will decrease pressure.
(It can be locked by pushing the knob in.)
Note : Set the normal operating air pressure to 0.4MPa.

7
- Lift Control Switch (UP/DOWN/PRESS)
Function : Raising/Lowering the lift.
“UP”------- Used when raising the lift. The lift moves up by air pressure.
“DOWN”--Used when lowering the lift. The lift moves down by its own weight.
“PRESS”- Used when setting the inductor plate in a pail and filling the inductor plate with material.
The lift speed is maintained at a constant level by the speed controller attached on the air inlet of the
air cylinder of the lift.
To operate : Adjust the switch to each position depending on the intended use.
Note : At the “PRESS” mode, be careful not to put excess pressure on the lift. Material may escape through
the side of the packing around the inductor plate. Also, do not push “AIR” button during the “PRESS”
mode.
- AIR button, Inductor Plate
Function : Separating the inductor plate from a pail when a pail becomes empty.
To operate : Air is supplied as long as the button is depressed.
Note : Pressing the button when a pail is not empty may be a cause of air bubbles in material.
- Bleeder Valve
Function : Removing air from the pump and inductor plate after setting the inductor plate in a pail.
To operate : Holding the hexagonal head with a wrench (13mm), counterclockwise turn will open the valve.
Clockwise turn (all the way) will close the valve. 3-4 turns will be enough for bleeding.
Note : Be sure to close the valve securely after releasing air.
- Air Release Plug
Function : Removing air from the pump and inductor plate when setting the inductor plate in a pail. Open the
plug before inserting the inductor plate into a pail and close it once material comes out of the air
release hole.
To operate : Open and close by turning the plug holding the handle on the top by hand. Left turn will loosen the
plug. Right turn will tighten the plug. Be sure to securely turn it when closing (tightening).
3.2 Placement of pail
1）Adjust the lift control switch to “DOWN” before turning on air supply.
2）Gradually increase lift air pressure to 0.4MPa by adjusting the lift air regulator knob. Then adjust the lift control
switch to “UP” to raise the lift to the full height.
3）Turn the air release plug on the inductor plate 2-3 times counterclockwise to loosen it.
4）Place a 20 litre pail right under the inductor plate.
5）Turn the lift control switch to “DOWN” to lower the lift.
6）If the inductor plate and a pail are not concentric when the inductor plate reaches the brim of a pail, set the lift
control switch to “UP” to raise the lift and then readjust the position of a pail.
7）If the inductor plate cannot be inserted into a pail smoothly when the inductor plate reaches the brim of a pail, set
the lift control switch to “PRESS” to release the air built up between the inductor plate and material via the air
release plug. Keep releasing air until material comes out of the air release plug.
8）Once the air inside the inductor plate is completely released, adjust the lift control switch to “DOWN” and tighten
the air release plug.
9）In the event material doesn’t come out of the air release hole even though the lift control switch is set to
“PRESS”, please follow the following procedure:
①Close the air release plug on the inductor plate.
②Close the valve on the piping to prevent material from being discharged.
③Open the bleeder valve by turning it 3-4 times for releasing air.
④Open the air valve for the pump and increase air pressure gradually with the pump air regulator. The pump
will start operating at approx. 0.05MPa. Adjust the pump air regulator to set pump speed to 5-8 seconds per
cycle.
⑤Set the lift control switch to “DOWN” to allow material to come out of the bleeder valve.
⑥Once material comes out, adjust the lift control switch to “DOWN” and close the bleeder valve. Then, close
the air valve for pump and set the pump air regulator to 0MPa.

3.3 Operation
CAUTION
- Material, if containing air bubbles, may gush out when discharged. Put a plastic bag over the
material outlet to receive spurting material.
- Do not exceed the maximum operating pressure of the pump (0.7MPa). Overpressure may cause a
product failure resulting in serious personal injury and/or property damage.
- The maximum operating pressure of the lift is 0.7MPa. Overpressure may cause a product failure
resulting in serious personal injury and/or property damage. Do not exceed this limit.
At the “PRESS” mode, be careful not to put excess pressure on the lift. Material may escape
through the side of the packing around the inductor plate.
- Keep your hand away from the three studs connecting the air motor and lower pump. Fingers can
get caught in the reciprocating plunger.
- If a defect occurs during lift operation, immediately stop the lift by adjusting the lift control switch to
“DOWN” or shut down air supply to the unit.
- Keep yourself away from the lift when operating it. Do not touch any part of the unit other than the
control switches.
- Do not put your hand or any other parts of your body between a pail and the inductor plate when
installing a pail. An unexpected body injury may be caused.
- To prevent excessive pressure in a pail, do not push the “AIR” button when the lift control switch is
set to “PRESS”.
- If the “AIR” button is pushed when there is still material in a pail, air bubbles will be produced in
material.
- When the lift stops due to a foreign object caught in the sliding part, be sure to move the lift to the
opposite direction BEFORE removing an object. The lift may suddenly start moving if a foreign
object is removed directly.
1）When filling the delivery piping with material for the first time, the air inside the piping will blow out. Please follow
the following procedure.
①Put a plastic bag over the material outlet to receive discharged material.
②Open the valve on the delivery piping.
③Open the air valve for the pump and set the pump air regulator for minimum operating pressure.
④The pump will start discharging material from the outlet. Once the air in the piping is released completely, close
the air valve for the pump and set the pump air regulator to 0MPa.
⑤The pump is now ready for operation.
2）Adjust the pump air regulator to set to the desirable operating pressure. An estimate of the material discharge
pressure to the supply air pressure is calculated by “supply air pressure × pump ratio”.
(e.g. When operating a 38:1 ratio pump at 0.7MPa supply air pressure, material will be discharged at approx.
26.6MPa.)
<NOTE>
- If the viscosity of the material is high or climate is cold, please switch the “lift control switch” to “PRESS”.
Pressure can be adjusted by lift air regulator in accordance with the viscosity of the material (up to 0.7MPa).
If the pressure is too high, the material may leak from packing of the inductor plate. Please set the optimum
pressure while operating (if the work is aborted, switch the “lift control switch” to “DOWN”).
- Material viscosity changes with seasons. It is recommended to make a note of appropriate pressure for each
season.

9
3.4 Replacement of pail
CAUTION
- Do not try to separate the inductor plate from a pail at once with the “PRESS” button depressed.
Compressed air built up inside a pail may be released causing a spurt of residual material.
1）When a pail becomes empty, the pump will run dry and NOT stop automatically. Close the pump air valve and
adjust air pressure to 0MPa using the pump air regulator.
2）Set the lift control switch to “UP” to raise the lift to the upper limit.
3）Press the “AIR” button a few times to allow air to flow between the inductor plate and a pail. A pail will be
gradually separated from the inductor plate by rotating it. When a pail is hard to remove, push the “AIR” button
several times again and then rotate a pail slowly to separate it from the inductor plate.
4）Once the inductor plate is separated from a pail, set a new pail according to the procedure described in “3.2
Placement of pail”.
3.5 After work
CAUTION
- After work or when shutting down the unit for a long period, be sure to turn off the air supply source
to disconnect air supply to the pump, and open the valves on the material outlet or gun to release
residual pressure inside the pump and piping. Failure to shut off air may cause damage to the hoses
and pipes and/or leak in the valves and gun. Any secondary accidents caused by the failure
mentioned above are the responsibility of the users.
1）Close the air valve for the pump and set the pump air regulator to 0MPa.
2）Set the lift control switch to “DOWN”.
<NOTE>
[Air release plug on inductor plate]
- When using the “air release plug” for the first time, it should be positioned on the upper side to release air more
efficiently.
- It’s recommended that if there is no residual material inside the inductor plate, when replacing a pail, position
the “air release plug” on the upper side and release air. Also if material is left inside the inductor plate, switch
the position of the “air release plug” and the “plug” to release air from the lower hole. However, this may not be
applied to some materials or situations.
[Filter on inductor plate (flat packing type)]
- In the flat packing type, a punch plate is attached on the bottom of the inductor plate to make it possible to use
up material in a pail as much as possible.

- Remove foreign object.
- Replace worn part.
Pump doesn’t run
and air leaks from
silencer
- Foreign object is caught between spindle (716299) and valve switcher
(832996) in air motor (804814).
- There exists damage that prevents sliding movement of parts below.
- Remove foreign object.
- Replace damaged part.
Pump doesn’t draw
material at firs t time
of operation
Pump operating speed is so fast that lower pump suction cannot keep up with
pump movement. (Valve inside lower pump is not working well.)
Set pump speed to 5-8 sec. per cycle until
material is pumped out.
If upward movement of plunger is faster,
- seat surface of piston valve is defective (wear of seat surface, inclusion of
foreign material) or,
- packings are damaged.
If downward movement of plunger is faster,
- seat surface of foot valve is defective (wear of seat surface, inclusion of foreign
material),
- packings are damaged, or
- shovel rod is bent.
If downward movement of plunger is faster, operating speed is so fast that lower
pump suction cannot keep up with pump movement. (Vacuum is caused inside
lower pump.)
Decrease air pressure until material
comes out. (This pressure is the upper
limit of normal operating pressure.)
Connecting rod connecting air motor and lower pump is completely separated
from air motor. (In this case, parts inside of lower pump may be damaged.)
Inspect inside lower pump first, then
replace damaged part, and retighten each
part.
Leak occurs in delivery pipe.
Leak occurs in lower pump (connections are loosened or o ring, backup ring, or
packing is damaged).

4.3 Consumables
1）Pump
Refer to “Instruction Manual for APP 067U” for replacement time for consumables used in the pump. The
replacement time should be used only as a guide. Consumption varies depending on use conditions. Also, be
sure to replace a part when you find any defect like a leak during operation.
2）Lift
- The plastic tubes will be degraded naturally. Replace them all every six years.
- The switches and regulators should be replaced if you find they are not working properly. Never use a defective
device.
3）Inductor Plate
- The packing will get worn out due to sliding contact with a pail.
- The gasket used for the connection between the pump and inductor plate will get worn out by repetitive
mounting and removal of the inductor plate. Replace it with a new one when it is damaged at the time of
inductor plate removal.
