2. Principle of Operation
The YAMADA Air-powered Pump is a reciprocating type pump that is driven by compressed air. This pump consists
of an air motor to drive the pump and a lower pump to draw up the liquid material as shown in the figure.
2.1 Function of the Air Motor
1) In the status shown in the figure at right, the air piston reaches the
upper limit and is now about to go down.
2) The compressed air fed from the air supply port is applied to the
chamber A through the air passage tube from the path provided in
the lower part of the slide valve. The air pressure of the chamber
B is discharged out through the slide valve.
3) As a result, the air piston starts to go down.
4) When the air piston collides with the trip shoe, the slide valve is
momentarily tripped downward by the function of the trip
mechanism.
5) As a result, the air supply is conducted to the chamber B and the
chamber A is conducted to the exhaust port, so that the air piston
is changed to go up.
6) Thus, the air motor continues its reciprocating motion
automatically as long as the supply air is fed to it.
2.2 Function of the Lower Pump
1) The lower pump integrated with the air motor traces the
reciprocating motion of the air motor.
2) This reciprocating motion of the piston causes a sucking operation
and a compressive operation to the suction valve and the piston
valve of the lower pump, thereby discharging the liquid
intermittently.
3) This reciprocating motion is automatically continued until the
delivery side is closed and the liquid compressive pressure of the
lower pump is balanced with the pressure of the air motor.

3. Preparations before Operation
1) First loosen the pan-head screw and take out the pump from
the cabinet.
Remove the rubber cap at the bottom of the pump Ass’y, insert
the pump into the cabinet, and fix it with a pan-head screw.
Refer to <Assembly of Equipment> indicated on the top
surface of the corrugated fiberboard case. (Fig.1)
2) Loosen the two clamping nuts at the bottom of the cabinet
(turn them counterclockwise), and remove the cabinet from the
base frame. (Fig.2)
3) Transfer the oil to the exclusive use oil can. (Fig.2)
4) Place a oil can in the middle of the base frame and install the
cabinet as it was. Tighten the clamping nut on both sides
equally. (Fig.2)
5) Install the attached hose and the gun at the oil discharge port
of the pump, and clamp the connecting portion securely.
6) Connect the attached air coupler to the air hose and fix it with
a hose band. (The air hose is separately available.) If the air
coupler to be connected to the compressor is not available,
purchase it separately.
7) When the air coupler is connected to the pump, the pump will
be operated for a while, and the pump and hose will be filled with oil.
After that, the pump operation will stop. If the gun lever is pulled in
this status, the oil lubricator can be used any time.
<Note>
- Install the air regulator (separately available) at the air supply port
of the pump. The dedicated air regulator is available as the
standard product. Please use it
- Using the air regulator permits adjusting the supply air pressure to
the pump and reducing the wasteful motion of the pump, with the
result that the operability is improved and the pump life is extended.
In the normal operating status, the pointer of the pressure gauge
should be at 0.3 to 0.5 MPa.

4. How to Operate the Machine
WARNING
- When the machine is operated, electrostatic sparks may give a shock to the human body or cause
death or bodily injury due to a fire or explosion. Be sure to perform grounding securely by using a
grounding conductor according to the operating environment.
CAUTION
- The supply air pressure should be 0.7 MPa or less. If the primary pressure is more than 0.7 MPa,
install an air regulator on the air line and adjust the pressure to 0.7 MPa or less.
- After the end of daily work or when the machine is not operated for a long time, be sure to shut off the
supply air and open the discharge port valve to bleed the internal pressure of the pump and hose. Any
secondary accident such as pollution of installation, due to hose damage or leakage from the valve
without shutting off the supply air, shall be attributable to the user’s responsibility.
- During machine operation or after completion of movement, be sure to lock
the caster brake for locking. A turnover of equipment may pollute the
installation. (Fig.3)
- During oil change, take extreme care not to allow sand and dust to adhere on the suction tune of the
pump. If sand is mixed in the oil, it will give breakage to the pump and also damage to the important
machine.
<Note>
Using the air regulator permits adjusting the supply air pressure to the pump and reducing the wasteful motion of
the pump, with the result that the operability is improved and the pump life is extended. In the normal operating
status, the pointer of the pressure gauge should be at 0.3 to 0.5 MPa.
1) First loosen the pan-head screw and take out the pump from Before
starting oil supply, be sure to turn the knob of the oil meter
counterclockwise to reset to the “0” position.(Fig.4a)
2) The pump is operated by pulling the lever of the oil gun, and oil is
discharged. To continuously discharge the oil, hook the lever to the
hardware provided at the gun rear. (Fig.4b)
If the discharge oil pressure is so high as to cause splashes, adjust the
supply air pressure with the air regulator.
3) After completion of oiling work, be sure to shut off the supply air of the
pump and bleed the internal air of the hose. For bleeding the internal
pressure of the pump and hose, Insert the oil gun in the return hole of
the lid and pull the gun lever. (Fig.5)

2) Inject a few drops of lubricating oil (approx. 0.5 ml) into the air supply port as shown in
the figure at right.
Use turbine oil class 1 ISO (VG-32) or equivalent as the lubricating oil.
[Inspection]
1) Oil is a fluid and easily polluted. Keep it clean at all times.
2) To protect the oil meter, a filter is installed between the pump and
the oil gun. If filter clogging occurs, the oil flow is get worse. Clean
the filter sometimes. (Fig.7)
3) The oil-proof hose is a consumable product. Check it periodically.
If any blemish or leakage is found, replace the hose a little earlier.
4) The packing of the pump will be worn away. Check and replace it
at least once a year.
6. Disassembly and Assembly
When the pump operation becomes defective or stops, do not disassemble the pump thoughtlessly but refer to the
item on P.5 (Troubleshooting and Corrective Measures), and judge the condition carefully and disassemble only the
minimum necessary parts.
