2 Before Use/During Use 2-1. To ensure safety and prevent hazard
WARNING
Be sure to observe the warnings, cautions and prohibitive instructions described in this operation manual. Failure to observe these instructions causes damage to the pump, and can result in damage to the surrounding machinery or injuries.
If the diaphragms are damaged, the fluid spouts from the exhaust port through the air pressure valve, or air is mixed with the fluid. This can result in a serious accident depending on the property of the fluid.
To use a fluid that may cause injuries or property damage, be sure to take appropriate preventive measures (exhaust disposal measures etc.), and be sure to observe the following instructions.
When this pump is used in an atmosphere that may cause spontaneous ignition, or when a highly flammable fluid is fed, circulated or used for cleaning at a high speed, this can cause electrostatic sparks, ignition or heating which gives shock to the human body, and can result in injuries or property damage from a fire or explosion. Be sure to ground the pump with the supplied ground cable, and provide ventilation depending on the operating environment.
Make sure that the supplied pressure does not exceed the maximum operating pressure (0.7 MPa). Operating the pump under a pressure higher than the maximum operating pressure can result in pump damage, causing injuries or property damage. Be sure to purchase the air pressure regulator or air pressure filter regulator, and mount it to the pump.
Be sure not to use a fluid incompatible with the material of the fluid contact parts of the pump, or a solution that may cause explosion. Using such a fluid or solution develops a chemical change involving extremely hazardous explosion. This can result in injuries (including death) or damage to properties (building, equipment, etc.).
This pump cannot use a fluid that may affect the materials of the fluid contact parts and the diaphragms. Referring to the compatibility table included in the catalog, select the pump model compatible with the fluid being used. Using a pump incompatible with the fluid may result in fluid leak or damage. For compatibility between the pump and fluid, consult TAIYO sales office.
Before daily operation, be sure to check the pump for fluid leak. If there is a defect, do not use the pump. Contact TAIYO to order inspection or repair.
Before Use/During Use / Part Names 3
WARNING
Do not use consumable parts (diaphragms etc.) longer than the replacement interval specified in “Maintenance” of this manual, and conduct early maintenance. Do not use a part that has been left for at least one year from the date of purchase, even if it has not been used. It may be deteriorated by secular changes.
If abnormality is found in pump operating conditions, stop operation, and contact the nearest TAIYO sales office listed on the last page.
To use a fluid with toxicity or smell, ensure through ventilation.
Do not discharge chemicals or other harmful substances that the pump handles directly onto the installation floor. For disposal of harmful substances, follow the regulations applied to the substances.
If the pump availability factor per certain period increases, replace the consumable parts (diaphragms etc.) earlier than the specified replacement interval.
2-2. Exemption from responsibility Use the pump properly according to this operation manual. Failure to observe the warnings, cautions and prohibitive instructions described in this manual, or improper handling of the pump causes damage to the pump, and may result in damage to the surrounding machinery, or injuries.

The pump sucks up and feeds a fluid by horizontally moving two diaphragms mounted to both ends of the spool topressurize/depressurize the fluid chamber.
Fluid chamber (A)
Fluid chamber (B)
Exhaust port Exhaust port
Air chamber (a) Air chamber
(b) Suction port Suction port
When compressed air is fed into the air chamber (a), the spool moves to the left to push the fluid out of the fluid chamber (A). At the same time, the fluid is sucked into the fluid chamber (B).
When the spool moves to the left stroke end, the air pressure valve is switched so that the compressed air is fed into the air chamber (b) on the right, and then the spool moves to the right.
When the spool moves to the right, the fluid in the fluid chamber (B) is pushed out of the chamber. At the same time, the fluid is sucked into the fluid chamber (A). The pump repeats this operation cycle.
Installation 5
6 Installation 6-1. Precautions for installing and mounting the pump The pump service life depends on whether the installation condition is proper or not. Pay attention to the following points:
WARNING
When this pump is used in an atmosphere that may cause spontaneous ignition, or when a highly flammable fluid is fed, circulated or used for cleaning at a high speed, be sure to ground the pump with the supplied ground cable, and provide ventilation depending on the operating environment. Failure to observe this instruction can result in injuries and property damage from a fire or explosion.
Make sure that load and vibration of the piping is not applied to the pump body. Otherwise, a fluid leak may occur, and air may be mixed with the fluid. This may result in injuries or property damage depending on the property of the fluid.
CAUTION
For connections of the pump suction and discharge ports, use a hose or flexible tube to absorb pump vibration.
Never attempt to step on, or hang down from the diaphragm pump. Such an action may result in injuries, or causes a failure of the pump.
Set the suction head as small as possible. The maximum suction head is approx. 6 m (when fresh water is used). Providing a larger suction head increases the suction resistance. Also, when the fluid viscosity is high (3000 mPa s), the suction resistance becomes large. This may reduce the discharge rate, and cause pump internal damage due to shortened life span of the diaphragms, or cavitation*. (* Refer to “Terminology”)
To install the pump, be sure to take appropriate vibration-absorbing measures in consideration of the installation place.
(1) Installation place: Install the pump on a level place. Avoid
using the pump in an inclined place. (2) Mounting orientation: Be sure to mount the pump so that the
arrow indicated on the cover faces up. (3) Installation method: Fasten the support brackets securely so that
the pump and the piping will not be damaged by vibration.
Arrow Cover
The direction of fluid flow (suction port and discharge port) can be reversed. Refer to “Maintenance Procedure” described later.
6 Installation
6-2. Precautions for piping (Connections with suction port and discharge port)
CAUTION
Select appropriate pipes in consideration of size, fluid-compatibility and pressure resistance. Using improper pipes may cause a fluid leak or pump failure.
Before connecting the pipes, flush the pipes to prevent swarf, sealing tape waste, rust or other foreign bodies from entering the piping. Intrusion of foreign bodies will cause pump malfunction.
During piping, make sure that the pump body is not subjected to lateral load. Otherwise, the screws in the pump suction port and discharge port may be damaged, causing a sealing failure or other troubles.
For connections with the pump suction port and discharge port, use hoses or flexible tubes to absorb pump vibration.
Use pipes that will not crash under negative pressure when the pump sucks up the fluid.
Use pipes with an inner diameter larger than the discharge/suction port bore diameter. If the pipe inner diameter is too small, the pump cannot provide sufficient performance.
To protect the pump, mount a filter or strainer to the pump suction port. 6-3. Precautions for piping (Connection of air pressure)
CAUTION
Before connecting the air pressure pipe, make sure that the air supply is stopped. Otherwise, the pump may abruptly operate, resulting in injuries and property damage.
Make sure that the supplied air pressure does not exceed the maximum operating pressure. Supplying a higher air pressure may result in injuries and property damage. (Operating air pressure: 0.2 to 0.7 MPa)
After operation is completed, or during night, stop supplying air pressure, and release residual pressure from the piping and the pump. If the piping has a crack or the diaphragms are damaged when the air pressure is supplied, the pump continues operation, and the fluid may continue to leak out. Such derivative damages shall be under responsibility of the user.
Never attempt to mix a general antifreeze solution into the oil in the air pressure lubricator mounted to the air pressure supply port. It may have bad influence on the human body. Mount the air pressure filter, regulator and lubricator (three items/set) to the air pressure supply port to supply clean air and lubrication oil. When mounting these components, set the distance from the diaphragm pump as short as possible. The mounting distance has influence on the pump durability and performance.
Mount the air pressure filter, regulator and lubricator (three items/set) to the air pressure supply port at the shortest distance from the diaphragm pump.
For the air pressure piping, use a pipe with an inner diameter larger than the air supply port bore diameter (Rc1/4, TD2: Rc3/8).
To use a new pipe, flush the pipe before connecting it to the pump, to remove swarf, dust or other foreign bodies completely. Foreign bodies in the pipe will cause malfunction of the air pressure valve.
Make sure that the supplied air pressure does not exceed the maximum operating pressure (0.7 MPa).
Operation 7
7 Operation 7-1. Checking the pump before operation
CAUTION
Make sure that the pump has been properly installed, and that the mounting bolts are not loose. Operating the pump with the mounting bolts loosened may result in injuries or damage to the surrounding machinery.
To use a highly flammable fluid, be sure to ground the pump with the supplied ground cable. Operating the pump without connecting the ground cable may result in injuries and property damage from a fire or explosion.
Make sure that the pump has been securely installed on the operation site. Set the pump suction/discharge piping individually. Check the connections with the pump for looseness. Make sure that the air pressure regulator has been set to the minimum operating pressure (0.2 MPa). Make sure that the air pressure lubricator has the lubrication oil <JIS K2213-Class 1 (Additive-free turbine oil ISO VG32)>.
7-2. Checking the pump through trial run
CAUTION
Do not continue idle run for a long period. This may result in unexpected wear, and causes a pump failure.
Make sure that the pump has been properly installed so as to absorb vibration. Check the pump for a fluid leak.
To conduct a trial run, increase the air supply pressure gradually from the minimum operating pressure. After confirming that the pump normally operates, increase the air supply pressure up to the set pressure.
7-3. Checking the pump in operation
CAUTION
For control of discharge rate through adjustment of supplied air pressure, the allowable fluid suction flow rate varies depending on the viscosity and specific gravity of the fluid, suction head and other operating conditions. If the fluid suction flow rate exceeds the specified flow rate, the pump operates at a higher speed, causing cavitation in the fluid. Such a condition rather reduces the discharge rate, and shortens the diaphragm service life. (*Refer to “Terminology”)
It is not dangerous to leave the pump at rest with the discharge port valve closed while air pressure is being supplied. However, if the pump is left in this condition without being watched for a long period or during night, the pump starts operation in case where the fluid leaks from the piping or diaphragms, and continues to discharge the fluid from the leak portion. To leave the pump at rest for a long period, stop supplying air pressure, and open the valve at the discharge port to release residual pressure from the pump and discharge piping.
If the pump is at rest for a long period after using a fluid that contains slurry, the slurry is deposited in the pump or adheres to the pump. This may cause damage to the diaphragms at the next operation, or apply bending torque to the disk, resulting in a bend or break of the spool. After the pump is at rest for a long period, clean inside of the pump to eliminate slurry completely before restarting it. To leave the pump at rest for a long period, flush the pump with a solution compatible with the pump material. Otherwise, the next pump operation may be disabled, or the pump performance may be remarkably deteriorated by adhesion of the residual fluid.
If the pump is used in winter or in a cold environment, the air valve or silencer may freeze due to heat insulation expansion during pump operation. This may remarkably deteriorate the pump performance, or stop the pump. In such a case, contact TAIYO sales office or contact center listed on the last page.
8 Maintenance (Parts)
8 Maintenance (Parts)
WARNING
Only people who gained thorough experience and knowledge can conduct maintenance and inspection.
Before conducting maintenance or inspection, carefully read the “Maintenance Procedure” in this manual to understand the procedure thoroughly. Failure to follow the specified maintenance procedure can result in serious injuries and property damage.
Never attempt to conduct maintenance or inspection when the pump is in operation. Maintenance or inspection during operation can cause injuries.
Before conducting maintenance or inspection, stop supplying air pressure, and completely release residual air pressure from the pump and piping. Residual air pressure in the pump or piping causes injuries and property damage.
To tighten the bolts, follow the specified tightening torque. Tightening the bolts with torque higher or lower than the specified value will cause malfunction or failure of the pump, or other accidents.
For replacement, use TAIYO genuine parts. Replacement with other manufacturer's parts may deteriorate the pump performance, and causes malfunction of the pump.
Continuous use of the pump without maintenance or inspection may cause damage to the pump, or result in damage to the surrounding machinery, or injuries.
TAIYO shall not be responsible for any damage, accident or failure attributable to the above factors.
8-1. Daily inspection (Check the pump every two or three days.)
CAUTION
If the lubrication oil in the air pressure lubricator mounted to the air pressure supply port has exhausted, the pump cannot be properly lubricated, causing malfunction.
Filling oil (machine oil, spindle oil, etc.) other than JIS K2213-Class 1 (additive-free turbine oil ISO VG32) deteriorates the pump performance due to swelling of the packing in the pump, and causes malfunction of the pump.
To lubricate the air pressure valve of the pump, refill oil into the air pressure lubricator mounted to the air pressure supply port. The refilling interval depends on the pump driving frequency.
To refill oil into the air pressure lubricator, use JIS K2213-Class 1 (additive-free turbine oil ISO VG32) or equivalent oil.

8-2. Periodic inspection
CAUTION
Periodically remove condensate and foreign bodies clogged in the filter at the air pressure supply port. If condensate enters the pump, lubrication oil supplied from the lubricator is washed away. This may deteriorate the pump performance, and cause malfunction of the pump.
If the diaphragms are damaged due to failure or delay of the periodic inspection, the fluid enters the air pressure circuit in the pump, causing malfunction of the pump. Furthermore, the fluid will be discharged from the exhaust muffler, which may result in injuries. If air is mixed in the fluid, it may result in an accident. Refer to this section and “Maintenance Procedure” described in this manual.
