1. Part Names
1.1 Part names
Fig. 1 shows the names of each part used in the instructions in this manual. Use them as a reference.
1.2 Contents of a package
The unit is packed in a wooden box.
Please make sure no damage during shipment and no missing accessories after unpacking as soon as possible.
Please make sure no loose screws, piping connections, and fastener components.
Please retighten if any screws, piping connections, and fastener components are loose.
(The nylon tube and the silencer are detached from the pump in the packaging due to the shipping conditions.)
2. Operating principle
Yamada's air-powered pumps employ reciprocating motion system driven by
compressed air.
It is comprised of two sections as illustrated at right; air motor section which
drives the pump and lower pump section which pump up material.
When compressed air, generated by the compressor, is fed into the air motor, the
air switching mechanism built in the air piston actuates vertical reciprocating
motions. The connecting rod, joining the air piston inside the air motor and the
piston inside the lower pump, transmits the movement to the piston inside the
lower pump, giving vertical reciprocating strokes.
Vertical reciprocating motions, generated by the lower pumps, feed material into
the lower pump. Then, it is pumped out of the discharge port.

3. Preparation of Installation and Operation
<NOTE>
If you have purchased a complete pump unit, refer to the instruction manual for the unit for installation,
operating method, and other instructions.
WARNING
- The pump weighs about 30kg. Be careful not to let the pump fall over or
get crushing injury during installation.
- Do not put your hand between the pump body and shovel. Hand injury
may be caused by a sudden movement. (Fig. 3)
CAUTION
- Consider nearby equipment when installing the unit.
- Fall prevention measures
When using the pump individually, install it on either of the following types of mount in accordance
with the instructions below.
A stationary mount---- Secure a mount to a flat floor using anchor bolts or the like to prevent the
pump from falling.
A movable mount------ Be sure to maintain balance of the pump to prevent a fall due to vibration.
Use a stopper, caster wheel with a brake, or other locking device to prevent a
mount from moving due to reciprocating pump vibration.
- Before installing the pump, verify that the shovel at the bottom is NOT sticking out. Failure to follow
this instruction may result in damage to the shovel rod causing a pump failure. (Fig. 3)
- Set each air regulator to 0MPa BEFORE connecting an air hose to the pump.
- Apply sealing compound or sealing tapes to the male screws and tighten tightly when the pipes are
connected.
Be careful not to allow the sealing materials to enter the piping.
Do not apply the tip of the terminal (two thread ridges) to maintain conductive property of the
ground.
(However, no applying is necessary if it will be connected to the hose union.)
Check that there is no leakage or electrical continuity in each part after connecting the piping.
- The packings and O rings used in the pump are made of NBR, Urethane, or Oxhide. Do not use any
solvents that are incompatible with these materials for cleaning.

3.5 Connecting suction piping (connecting piping except inductor plate)
As the pump start operation, the shovel in the suction port starts
reciprocating. Do not place any piping equipment in the operating range
of the shovel.
Refer to Fig. 7 for the operating range of the shovel and mounting
dimension for piping.
Apply leak prevention, putting a gasket, for example, to the connection
between the flange section of the material inlet of the pump and piping.
3.6 Discharge piping
1）Connect a discharge hose to the pump outlet. Make sure the hose satisfies the following requirements:
- Resistant to material being pumped and unaffected by environment
- Satisfying the following normal operation pressure:
-13×1 ratio pump: 10MPa or more
-25×1 ratio pump: 18MPa or more
-38×1 ratio pump: 27MPa or more
-50×1 ratio pump: 35MPa or more
- Recommended size: 3/4 inch or more
- When mounting the pump on an elevating machine like a lift, be sure to use a flexible hose with an adequate
length in order not to be affected by up-and-down movement.
- Hose fitting or joint: <140 Type>Connectable to G3/4(F) material outlet, hose union with a 30 degree male seat
<125 Type>Connectable to Rc3/4 material outlet
2）Connect the other end of the hose to a delivery pipeline. Attach a valve at the connection between the hose and
the piping for maintenance and keep it closed until unit installation is completed.
3.7 Air piping
1）Connect air piping equipment such as an air valve and air regulator to the air inlet of the pump. Attach an
emergency stop valve to the air pipe (somewhere accessible between the air source and unit).
2）Select an air supply hose, fitting, and air equipment that satisfy the following requirements. With these devices,
connect an air piping and the air inlet of the lift. Be careful not to let the hose get caught on peripheral
equipment.
- Designed for use with air and unaffected by environment
- Normal operation pressure: 0.7MPa or more
- Recommended size: 3/8 inch or more
- Hose fitting or joint: Connectable to Rc3/8 air inlet
- Comfortable hose length for up/down movement of the lift
- Flow rate: 1300L/min (ANR) or more
<NOTE>
The air regulator controls supply air pressure to the pump. Accordingly, the pump operates efficiently without
unnecessary movement and thus the life of the pump can be extended.
3.8 Preparation for use
The pump has been tested using mineral oil before delivery. Please wash inside the pump with appropriate solvent
for the material being pumped.

3.9 Connecting the ground wire
WARNING
- Make ground connection when working with flammable material or in explosive atmosphere. Rapid
pumping of material can result in static electrical charge. Also, be sure to provide proper ventilation
where a flammable atmosphere may exist.
1) When installing the pump, be sure to connect the ground wire at the
specified position. (Fig. 8)
2) Also connect ground wires to peripheral equipment and piping.
3) Use 2.0mm2minimum ground wire.
4. Operating Method
CAUTION
- Keep your face away from the bleeder valve. Material may spurt out together with compressed air.
- 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.
- Keep your hand away from the three studs connecting the air motor and lower pump. Fingers can
get caught in the reciprocating plunger.
- Keep your face away from the silencer. Compressed air is exhausted at high pressure, causing
moisture to freeze leading cause of injuries.
- In case of a pump malfunction or shutdown, refer to “5.2 Troubleshooting” to judge the situation
thoroughly and disassemble the pump only as necessary.
- Avoid allowing the pump to run dry as much as possible. The life expectancy of packings will be
reduced. The pump runs dry when a container becomes empty. Stop the pump immediately after
the material in a container is all gone.
4.1 Description of valve
- Pump Air Regulator (sold separately)
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 (sold separately)
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.
4.2 Solvent cup (125 Type only)
1）The pump is equipped with a solvent cup to keep the packing from sticking to the plunger. Shut down the pump
and then fill the cup 2/3 full with suitable lubricant or solvent.
2）When lubricant in the cup runs out during operation, shut down the pump first and refill the cup.
Fig. 8 Position for connecting
the ground wire

4.3 Filling delivery piping with material
1）Open the bleeder valve by turning it 2-3 times for releasing air.
2）Open 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.
3）Air-containing material will be discharged from the bleeder valve. Put a plastic bag over the valve to receive
discharged material. Keep the pump operating until the air inside material is released completely. Then close the
bleeder valve by securely tightening it.
4）Close the air valve for the pump and set the pump air regulator to 0MPa.
4.4 Operation
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>
Material viscosity varies with changes in temperature. It is recommended to make a note of appropriate pressure
for each season.
4.5 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）Open the valve on the discharge port to release residual pressure on air and material inside the pump and
piping.

5. Maintenance and Inspection
CAUTION
- Be careful not to allow the pump and lift to accidentally operate during maintenance and inspection.
- When performing maintenance or inspection, notify workers by hanging a sign or other method to
keep them from touching the unit.
- Gasoline is a high volatile fuel. Never use it for cleaning of the unit. Risk of fire or explosion may
exist.
