- Discontinue it when you feel a hazard or abnormality during the work. And correspond according
to the troubleshooting.
- Stop pump operation immediately when a drum becomes empty. Running the pump dry will cause
excessive vibration, resulting in reduction of pump life and damage to other equipment.
- Before maintenance operation, be sure to stop air from being supplied to the pump, and release
the internal pressure (both air and material) of the pump. There is danger such as spouting of the
material when the maintenance work is done with air supplied.
- Do not discharge material directly onto the ground. Dispose of harmful materials according to the
requirements specified in MSDS or local regulations. Also, dispose of pump according to the local
regulations after removing residual material from inside pump. (Please contact industrial waste
disposal service.)
3/3
CAUTION
- Keep hands and fingers away from the pump during operation to avoid injury from moving parts.
- Use pump for the material suitable for the specification. Parts may be corroded and material leak
from the damaged parts can lead to environmental pollution. Also, follow handling notes (MSDS)
of the manufacturer about the handling of the material used.
- Take fall-prevention measures if using a slim or light tank. Risk of falling will be increased due to
shift in center of gravity caused by change in the material level in a tank.
- Take protective measures against rainwater and dust. It is likely to lead to the pollution of the
material.
- Be very careful about the edge of the pump when you lift the pump. Your hands might be injured.
- Be very careful about your posture when installing the pump. Back injury may be caused by lifting
the pump.
- Do not touch the surfaces of the pump and the hose when pumping high-temperature material.
Risk of burns exists.
- Stop the air supply source after the end of work when not using this pump for a long time such as
nighttimes and holidays. Also, open the valve of the exhalation port and liberate pressure in the
pump and the hose. There is a possibility of polluting facilities because of the damage of the hose
and the leakage of the valve. Such a secondary disaster becomes a responsibility on the user side.
- Place a drum on a flat, level surface to position pump horizontally against a ground. Operating the
pump on a slope may cause a fall or tip-over due to shift in center of gravity caused by change in
the material level.
- Material remaining inside or on the surface of the pump may spill out by inserting or removing the
pump into/from a drum. Be very careful not to get your clothing dirty.

2. Principles of Operation
A
V
A
The Yamada Air-powered Pump is a reciprocating
type that is driven by compressed air. The pump
consists of an air motor to drive the pump and a
lower pump to draw up the material as shown in the
figure at right.
When compressed air is supplied from the
compressor to the air motor, the air piston starts its
up/down motion by the function of the air switching
mechanism built in it.
This motion is transmitted to the piston of the lower
pump by the connecting rod that connects between
the air piston of the air motor and the piston of the
lower pump, thereby giving the up/down motion to it.
When the up/down reciprocating motion of the piston
of the lower pump is performed, the material is
sucked into the lower pump and fed out from the
discharge port by pressure.

4. How to Operate the Pump
WARNING
- The supply air pressure to the pump should be 0.7 MPa or less. Do not raise the pressure over 0.7
MPa in any case.
- Never bring the face close to the exhaust port of the pump that is in operation. The material is
discharged under high pressure, so water may congeal and injury may be caused by ice.
- If the air supplied to the pump is not shut off after completion of the work or at night, the hose
may be damaged or leak may occur on the valve or gun, thereby causing a secondary accident.
This secondary accident shall be attributable the user’s responsibility.
- If the pump goes to a malfunction or into an operation stop status, do not disassemble the pump
carelessly but refer to the item pertaining to <Troubleshooting and Corrective Measures> on P.4.
Judge the status properly and do not disassemble any component other than the component that
needs to be assembled.
<NOTE>
- After completion of the work or when the pump is not operated for a long time, shut off the air to stop the
supply air to the pump and open the discharge port valve to reduce the internal pressure of the pump and
hose.
- If the grease in the drum can has be exhausted, the pump is operated at a higher speed without grease
and has an adverse effect on its life. Stop the pump operation at once and replace the drum can with a
new one.
1) Turn the knob of the air regulator clockwise to supply air into the pump. When the supply air pressure
reaches 0.15 to 0.2 MPa, the pump starts to operate. The supply air pressure is indicated by the pointer
of the pressure gauge.
2) When air is supplied, the pump is operated for a while to fill the hose, pipe, and gun with grease, and
then stopped automatically.
If the pump is continuously operated without stop, leak may have occurred in any connecting portion of
the hose, pipe or gun. Stop the air supply and make a check.
3) Grease is discharged by operating the gun lever at the end of the material hose. When the lever is pulled,
the valve is opened and the pump is automatically operated to discharge grease.
When the lever is reset, the valve is closed to stop the grease discharge and the pump is also stopped.
4) Adjust the supply air pressure according to the application. Usually, the operating pressure should be
0.3 to 0.5 MPa. In particular, when the pump is used for feeding grease, the discharge volume differs
depending on the piping length and grease viscosity. Adjust the supply air pressure to your desired level.
5) After completion of the work, be sure to stop the supply air to the pump.
