WARNING
[Confirming adaptability, executing protective treatment]
-When handling flammable, combustible, or explosive liquid, or toxic liquid with corrosive nature or
acridity, confirm the adaptability of the pump in advance, and study/execute protective treatments that
fit the liquid in use.
[Caution on operation]
-When handling toxic or odiferous liquid, have adequate ventilation to prevent intoxication. Also, do not
fail to wear protective equipment (a safety mask, safety goggles, safety gloves, etc.).
-Never modify the pump since modification of the pump may cause jury or death accidents or failures
of the pump.
[Caution against explosion/fire accidents]
-When handling flammable or explosive liquid, do not bring anything which may build a fire around the
pump and a liquid container. Explosion/fire hazards may occur.
CAUTION
[Caution on beginning of use]
-When the pump is installed, avoid places below.
(1) A place with an atmosphere which causes corrosion on the pump (a place with chlorine gas
generated)
(2) A place with high temperature (60 °C exceeded) or below freezing around the pump
-Do not connect connections of the pump directly to piping but use flexible materials such as a hose
between the connections of the pump and the piping. If they are connected directly to the piping,
problems will occur such as noise occurrence by pump vibration, pipe damage, drum can
replacement unavailability, and pump maintenance unavailability.
-Supplying air which includes dust and water to the pump causes failures of the pump. Never fail to
use an air filter or others to supply appropriate air.
Use seal tapes or others to tightly connect the connections of the pump to hoses/piping to prevent liquid leakage/air
mixture from the connections.
a) Preparing pump
(1) Set the pump in a vise, and connect a hose*1, which is prepared separately, to the liquid outlet.
It is recommended that a hose union is used between the pump and the hose here.
(2) For SH-50B1 SUS (Siphon pump), additionally install the socket and bush, which are accessories of the
suction assembly (Product number: 803410) sold separately, to the liquid inlet of the pump, and connect the
liquid inlet to the main body of the suction assembly via a hose*2 prepared separately.
If other methods are used for piping, refer to “e) piping.”
*1: Use a discharge hose whose material is adaptable to the liquid in use and have 1 MPa of a pressure
capacity or higher.
*2: Use a suction hose whose material is adaptable to the liquid in use and have -0.08 MPa of a negative
pressure capacity or lower. (Not to be damaged with -0.08 MPa of negative pressure)

3
b) Installation/storage place
Avoid installing/storing the pump in places below.
(1) A place with an atmosphere which causes corrosion on the pump (a place with chlorine gas generated)
(2) A place with high temperature (60 °C exceeded) or below freezing around the pump
c) Air source
(1) Air pressure and air flow volume
Prepare an air source that allows the air pressure and air flow volume which satisfy the pump specification.
(2)Airquality
If watery air is supplied to the pump, freezing will occur in the upper pump, and the original performance
will not be maintained. Also, if dusty air is supplied, a packing and other parts may be damaged. Use an air
filter or others to remove water and dust.
d) Installation
(1)Installation location
Install the pump so that it is as close as possible to a liquid container and the height of the liquid surface is the
same as the height of the liquid outlet of the pump when the liquid is filled to capacity. If the liquid outlet of the
pump is lower than the liquid surface, even when the pump is stopped, a valve may be pushed up by liquid
pressure within the pump and the liquid may be transferred automatically. Pump failures may cause liquid
outflow; therefore, do not use the pump pushing in.
(2) Installation work
For DR-50B1 SUS (Drum pump)
- Install the supplied bang adapter to a larger port (2 inches) of the drum can, insert the pump to the port, and
tighten the wing bolt to fix the pump. At this time, to prevent damage of the drum can bottom, fix the pump
so that the pump is spaced from the can bottom by 2 to 3 cm.
- Install a drum can on a horizontal floor surface and fix it securely to prevent falling with pump vibration and
on disaster.
- Install/fix the pump so that the pump remains vertical.
For SH-50B1 SUS (Siphon pump)
- Install the pump on a wall surface using the mounting bracket (Product No.: 800400) sold separately. At this
time, to prevent dropping of the pump by its vibration or outer force, fix the pump firmly.
- When the pump vibration noise is transferred to a building or a structure, insert a rubber vibration insulator
between the mounting bracket and the wall surface.
- Install/fix the pump so that the pump remains vertical.
e) Piping
(1) Suction piping
- Use the piping material which is adaptable to the liquid in use and have -0.08 MPa of a negative pressure
capacity or lower.
- A long suction distance affects the pump performance.
- Never apply a push piping, but always apply a suction piping.
- If there is a risk of mixture of slurries or other foreign substances, attach a strainer to the head of the suction
piping.
(2) Discharge piping
- Use the piping material which is adaptable to the liquid in use and have 1 MPa of a pressure capacity or
higher.
- Install a valve to the discharge piping, apply end stop, and control the flow volume.

4
- A long discharge piping may damage itself because of water hammer phenomenon; therefore, open/close
the pump gradually using a manual valve. Avoid opening/closing rapidly using an automatic valve such as a
solenoid valve.
- Apply a relief circuit to a long discharge piping. The pressure increase with liquid volume expansion by
temperature raise within the piping may cause damage on the piping and the pump.
- If there is a risk of freezing of liquid in use, install a drain to discharge the liquid within the piping.
(3) Air piping
- Install an air valve (ball valve) and air decompression valve to the air piping, which are prepared separately.
If the air valve and air decompression valve are directly installed to the pump, to prevent damage on screw
parts by pump vibration and valve’s own weight, carefully select the piping joint material for connection.
- If clean air is unavailable, attach an air filter.
NOTE: Attaching an air coupler to the air inlet of the pump makes easier operations for drum can
replacement and maintenance.
3. Operating Method
1) Before using
Confirm the following warnings and cautions.
WARNING
[Confirming adaptability, executing protective treatment]
-When handling flammable, combustible, or explosive liquid, or toxic liquid with corrosive nature or
acridity, confirm the adaptability of the pump in advance, and study/execute protective treatments that
fit the liquid in use.
[Caution on operation]
-When handling toxic or odiferous liquid, have adequate ventilation to prevent intoxication. Also, do not
fail to wear protective equipment (a safety mask, safety goggles, safety gloves, etc.).
[Caution against explosion/fire accidents]
-When the pump is not filled with liquid (when the pump is used for the first time after purchase or after
disassembly/repair), do not operate the pump at high speed suddenly. Not only the sealing parts are
damaged, but also, if flammable or explosive liquid is handled, vaporizing liquid may be compressed
causing explosion. Never fail to start the operation at low speed adjusting the open degree of the air
valve and others.
Also, to prevent no-liquid running, implement a measure such as liquid surface control.
-When the pump is used for explosive liquid, use the pump with enough safety pressure.
-When handling flammable or explosive liquid, do not bring anything which may build a fire around the
pump and a liquid container. Explosion/fire hazards may occur.

5
CAUTION
[Strictly complying with pump specifications]
-Do not use the pump for specifications and purposes other than the ones specified. Injury or death
accidents and failures of the pump may occur.
-The maximum supply air pressure for the pump is 0.7 MPa. If higher pressure is applied, the pump
and the secondary piping may be damaged causing injury or death accidents/property damage.
Never fail to adjust the air pressure to 0.7 MPa or lower with the air decompression valve to use the
pump.
-The SUS304 is used for the parts where liquid contacts and fluorine-contained rubber (FKM) is mainly
used for the sealing parts of the pump. The pump cannot be used for liquid/chemicals which affect
those materials. If it is used, liquid leakage by corrosion may occur causing human body/property
damage.
[Caution on beginning of use]
-Abrasion/damage of packings causes liquid leakage from the pump. When the pump is used for liquid
which may cause human body/property damage, observe the following items fully.
(1) In preparation for unexpected liquid outflow by pump/hose/piping damage, execute a proper
protective treatment.
(2) Inspect for pump liquid leakage before use every day. If there is a leakage, investigate the pump
well and ask repair.
(3) If there is an abnormality in the pump operating condition, stop using it, and contact the dealer for
your purchase or our sales office.
[Caution on operation/handling]
-The pump has no switch to turn on/off the pump. Open/close the valve or attach/remove the air
coupler to start/stop the pump.
-While the pump is running, do not touch movable parts. If you touch them, your hands may be caught
in them and get injured.
-Do not drop/slap the pump. Failures of the pump may occur.
[Caution on end of operation]
-When the operation ends or when the pump is not to be used for a long time, never fail to disconnect
the air, and open the liquid outlet valve to remove the pressure in the pump, secondary hose, and
piping. The secondary disaster shall be user’s responsibility such as hose/piping damage without
disconnection of air and facility contamination by liquid leakage from a valve.
[Handling transferred liquid]
-Do not discharge the handled liquid directly to the ground. Comply with laws and regulations applied
for handling hazardous substances. Also, for safety, read carefully the handling precautions (MSDS)
by the manufacturer of the liquid in use to handle the liquid cautiously.
NOTE: Use the pump with the minimum necessary supply air pressure to minimize wear of the pump.
2）Preparing operation
When the pump is operated for the first time after installation or when it is re-operated after long time operation stop,
prepare the pump as follows:
(1) Clean enough inside of the piping and the container.
(2) Check for piping connection loose and pump connection screw parts loose.
(3) Wipe off dirt on the part of the pump or the suction assembly, which is inserted to the container, and set it to
the container.
(4) Set 0 MPa for the air decompression valve.

6
(5) Fully open the air valve, and gradually increase the pressure of the air decompression valve up to the level
where the pump almost starts to operate.
(6) In this operation status, remove the air in the piping with operation of the discharge piping valve.
3) Operation method
CAUTION
-Never operate rapid opening/closing for both the air valve and discharge piping valve. A water hammer
phenomenon may damage the piping and the pump.
(1) For control with operating discharge piping valve
While the discharge piping valve is closed, fully open the air valve, and set the specified pressure with the air
decompression valve. Then, control the pump with the discharge piping valve opening/closing.
(2) For control with operating air valve/air compression valve
Close the air valve, and set the specified pressure with the air compression valve. Then, control the pump with
the air valve opening/closing and opening position adjustment.
4）Running end operation
(1) Close the discharge piping valve or the air valve to stop the pump. However, if only the discharge piping valve
is closed, the internal pressure of the pump will be maintained
(2) To halt operation, close the air valve.
(3) To halt operation for a long period, disconnect the air source, and remove liquid from the pump and discharge
piping.
