WARNING
●Strictly observe the warnings, cautions and prohibited acts stated in this catalog. Failure to do so may damage the product or machines around it or cause personal injury.
●Fluids which corrosion or damage occur to the materials of the wetted parts in the body or the diaphragms must not be used. See the compatibility table in the catalog, and use an appropriate model. If an inappropriate model is used, fluid leakage or breakage may be caused. For the compatibility with fluids, contact our sales offices.
●Before using the pump every day, check for fluid leakage from the pump. If any abnormality is found, do not use it, and ask us to inspect and repair it.
●Service the wear parts, such as the diaphragms, earlier. Do not use any unused wear part which has been stored for more than 1 year after it was purchased. Aging deterioration may have occurred.
●If any abnormality is found in the operation of the pump, do not operate it, and contact our sales office.
●When handling any toxic or smelly fluid, sufficiently ventilate the working area.
●Do not discharge the handled harmful substances, such as chemicals, directly to the installation surface. Dispose of the harmful substances in accordance with applicable laws and regulations.
●If the pump operating time and frequency is increased, replace the wear parts, such as the diaphragms, earlier.
●When using the pump, set the supply pressure to the max. working pressure (0.7 MPa) or less. If it is operated at a pressure exceeding the max. working pressure, it may be damaged, thereby causing personal injury or property damage. Purchase a pneumatic regulator or pneumatic filter regulator, and fit it to the pump.
●Never use a fluid inapplicable to the materials of the pump wetted parts or an explosive solution. If such a fluid is used, a chemical change accompanied with very hazardous explosion may be caused, resulting in personal injury including death and damage to building and equipment.
●When the pump is used in an atmosphere which can cause spontaneous ignition or used to transfer or circulate a highly flammable fluid at a high speed or to clean with such a fluid, human bodies may receive a shock due to electrostatic spark, ignition or heat generation, or personal injury and property damage may be caused by fire or explosion. Be sure to ground the pump using the supplied ground wire and ventilate the working area in accordance with the specified conditions of working environment. (TD-08, 15 and 20 and TD2-25 types come with a ground wire, and TD-25 and 40 types come with a ground terminal.)
●When using a fluid which may cause personal injury or property damage, be sure to take appropriate protective measures (e.g. treatment of exhaust), and strictly observe the following instructions.
●If the diaphragms are damaged, the fluid may spout from the exhaust port through the pneumatic valve, or pneumatic pressure may be applied to the fluid, resulting in seriously hazardous situations depending on the properties of the fluid.

WARNING
CAUTION
●When the pump is used in an atmosphere which can cause spontaneous ignition or used to transfer or circulate a highly flammable fluid or to clean with such a fluid, ground the pump using the supplied ground wire or ground terminal, and ventilate the working area depending on the working environment. Failure to do so may result in fire or explosion accompanied with personal injury or property damage.
●The manifolds can be mounted by one of the following four methods. The suction and discharge ports can be turned 360° to any direction by loosening the clamps. To change their directions, completely loosen the clamps. If they are turned forcibly, the O-rings may be damaged, and sealing failure may be caused.
●Two types of check mechanism are available, i.e. the ball check type (standard) and the duckbill type (semi-standard) which enables the pump to transfer liquids containing fibrous solid.
●In the case of the duckbill type (semi-standard), the liquid flowing direction can be changed by reassembling the check mechanism parts. (See the figure below.)When reassembling, take care not to damage the parts. If any part is damaged, sealing failure may be caused.
●Prevent transmission of load or vibration to the pump body through the piping. Material leakage or entry of pneumatic pressure may be caused, and personal injury or property damage may occur depending on the type of material.
●To connect the pump on the suction and discharge sides, use hoses or flexible tubes which can absorb the pump vibrations.
●Never step on or hang on the diaphragm pump. Doing so may cause injury and damage the pump.
●The suction head should be as low as possible. The maximum head is approx. 6 m (in the case of clear water).
●The directions of the fluid suction and discharge ports can be changed to the opposite directions.
●Carefully select the installation place, and install the pump by an appropriate method to absorb vibrations.

Operation
1. Checking before operation
CAUTION
CAUTION
●When selecting the piping material, take into consideration the appropriate size, resistance to liquid and pressure resistance. Failure to do so may cause liquid leakage and breakage.
●Never add any general antifreeze to the oil to be poured to the pneumatic lubricator fitted to the pneumatic pressure supply port. This may be harmful to the health. Provide the pneumatic pressure supply port with a set of three items, pneumatic filter, regulator and lubricator, to supply clean air and lubricant. Install these three parts as close to the diaphragm pump as possible. The distance between them affects the durability and capacity of the pump.
●For the pneumatic piping, do not use pipes thinner than the pneumatic pressure supply port.
●Use the pump at a supply air pressure equal to or lower than the maximum working pressure, 0.7 MPa.
●When connecting new pipes, flush the pipes before piping the pump to completely remove cuttings and dirt. Failure to do so can cause operation failure of the pneumatic valve.
●Before piping, flush the pipes. Take care that cuttings, sealing tape fragments, dirt and rust never enter the piping. They can cause operation failure.
●Pipe the pump appropriately so that lateral load will not be applied to the pump body. Application of lateral load can damage the threaded portions of the suction and discharge ports and cause troubles, such as sealing failure.
●On the pump suction and discharge sides, use hoses or flexible tubes which can absorb the pump vibrations.
●Use pipes which are not deformed by the negative pressure caused by pump suction.
●Before connecting the pneumatic pressure piping, check that the supply of pneumatic pressure is stopped. If the supply of pneumatic pressure is not stopped, the pump may start suddenly, thereby causing personal injury or property damage.
●Use the pump at a supply air pressure less than the max. working pressure. Failure to do so may cause personal injury or property damage.<Working pneumatic pressure range: 0.2 to 0.7 MPa>
●After the completion of operation or at night, disconnect the supply of pneumatic pressure, and discharge the pressure from the piping and pump. If the piping is cracked or the diaphragms are damaged while pneumatic pressure is being supplied, the pump may continue to operate leaking the fluid. The user is responsible for these second accidents.
●Do not use pipes thinner than the discharge and suction ports. If the pipe inner diameter is small, sufficient performance cannot be obtained.
●Fit a filter or a strainer on the suction side to protect the pump.
CAUTION
●Check that the pump body has been installed correctly and the mounting bolts are not loose. If the pump is operated with mounting bolts loosened, personal injury or damage to machines around the pump may be caused.
●When the pump is used for an ignitable fluid, ground the pump using the supplied ground wire. If it is operated without grounding, a fire or an explosion may occur, resulting in personal injury or property damage.
●Check that the pump is firmly secured in position.
●Set the pipe on each of the suction and discharge sides. Check that the pipes of the pump are not loose.
●Check that the pneumatic pressure regulator has been set to the min. working pressure.<Min. working pressure: 0.2 MPa>
●Check that the pneumatic lubricator is filled with lubricant <JIS K2213 Class 1 (non-additive turbine oil ISO VG32)>.
2. Checking during test run
3. Checking in operating state
Maintenance (parts)
1. Routine inspection(Inspect the pump every two or three days.)
CAUTION
CAUTION
●Do not run the pump under no load for a long time. Doing so can cause unnecessary wear or trouble.
●The pump shall be maintained by persons with sufficient knowledge and experience.
●Never maintain or inspect the pump during operation. Doing so can cause personal injury.
●Before maintaining or inspecting the pump, stop the supply of pneumatic pressure, and completely discharge pressure from the pump and piping. If there is residual pressure in the pump, personal injury or property damage may be caused.
●Tighten the bolts to the specified torque.If any bolt is tightened to a torque higher or lower than the specified torque, accidents may be caused by nonconformity or rupture.
●Use our genuine replacement parts. If other manufacturers’ parts are used, the pump performance may be degraded, or the pump may malfunction.
●If the pump is kept used without mainte-nance, it may be damaged, machines around it may be broken, or personal injury may be caused.
●We are not responsible for damage, accidents or failures in any case.
●When the discharge flow rate is controlled by adjusting the supply of pneumatic pressure, the allowable specified flow velocity at which the material is sucked into the pump varies depending on the material viscosity, specific gravity and suction head. If the specified flow velocity ratio is exceeded, the pump runs faster, the material causes cavitation, and the discharge flow rate decreases, thereby affecting the life of the diaphragms.
●Even if the pump is kept stopped with the discharge port valve closed while the pump is under pneumatic pressure, it does not cause a hazardous situation. However, if the piping or diaphragm leaks while it is kept in this state for a long time at night or in an unattended state, the pump will start, and the material will be kept discharged from the leaking point. When keeping the pump stopped for a long time, stop the supply of pneumatic pressure, and open the discharge port valve to discharge the residual pressure from the pump and the piping on the discharge side.
●If the pump is kept stopped for a long time with a liquid containing slurry, the slurry will settle and deposit in the pump, and, when it is used next time, the diaphragms may be damaged or a bending torque may be generated on the disk to bend and break the spool. When the pump has been stopped for a long time, clean the inside to completely remove the slurry, and restart the pump.When the pump is not used for a long time, flush the pump with a solvent applicable to the material. Failure to do so may cause material deposition, thereby disabling the pump or significantly degrading its performance.
●Make sure that the pump has been installed correctly and vibrations are absorbed, and check for leakage.
●For test run, gradually increase the supply air pressure from the min. working pressure. After making sure that the pump operates normally, increase the pressure to the set pressure.
WARNING
CAUTION
●If all oil in the pneumatic lubricator at the pneumatic pressure supply port has been used and the pump is not lubricated, operation failure may be caused.
●If oil (machine oil or spindle oil) other than JIS K2213 Class 1 oil (non-additive turbine oil ISO VG32) or its equivalent is used, the seals in the pump may be swelled, thereby affecting the performance and causing operation failure.

●To lubricate the pneumatic valve parts of the pump, replenish the lubricator at the pneumatic pressure supply port with oil according to the number of times of operation of the pump. ●Periodically discharge the drain and foreign particles
which have collected in the air filter in the pneumatic pressure port. If the drain enters the pump, the oil supplied by the lubricator will be washed away, and the pump performance may be adversely affected. This can cause operation failure.
●The diaphragms, check balls and valve seats are wear parts. It is recommended to replace them when the number of times of use of the pump exceeds the specified number of cycles.
●If the diaphragms are damaged because the pump is not inspected periodically or is inspected late, the liquid will enter the pneumatic circuit in the pump, thereby causing operation failure. In addition, the liquid will be discharged from the exhaust silencer, resulting in bodily injury. Air may be included in the liquid, and unexpected accidents may be caused.
●For the pneumatic lubricator, use JIS K2213 Class 1 oil (non-additive turbine oil ISO VG32) or its equivalent.
CAUTION
The estimated life of the diaphragms is approx. 10 million cycles of operation. (Note: This number of cycles is not a guaranteed value. Inspect and replace the diaphragms using this number as a guide. However, if the liquid contains particles, such as metallic particles, cuttings and hardwearing particles, which can damage the diaphragms, their life will be reduced.)
If the external diameter of the check balls (initial value-TD-08: 12.7 mm, TD-15: 15.9 mm, TD-20: 20.6 mm, TD-25: 25.4 mm, TD-40: 38.1 mm, TD2-25: 34.9 mm) is reduced by 5% or more of the initial value or deformed, the contact between the check balls and the valve seats (sealing ability) is insufficient, and checking failure may occur. In such a case, replace the check balls.

●The pump discharge flow rate significantly varies depending on the quality of the liquid to be flow (viscosity, specific gravity and content of slurry) and transferring conditions (suction head, discharge head, transferring distance, piping diameter, etc.). When selecting the pump, sufficiently consider the piping resistance to the liquid quality, suction head and discharge head.
The pump discharge flow rate is determined by total of head which determined by piping diameter. If the discharge flow rate is not calculated correctly, troubles, such as insufficient flow rate, may be caused. The total head is determined by the friction loss determined by the actual suction head, actual discharge head and piping conditions as shown below. The friction loss varies depending on the piping diameter, length, the fluid average flow velocity, on the number of bends, the shape and number of valves.
●When determining the pump size, select a pump having a capacity of approx. 1.5 times the required discharge flow rate.
●If the piping distance is long and the friction loss is large, use one or two size larger pipes.
●Design the system so that the suction head is 6 m or less in the case of clear water. If the head exceeds 6 m, the discharge flow rate will significantly decrease, and the pump may not discharge the liquid.
●The above curve shows the change in discharge flow rate with viscosity with respect only to the pump. When selecting a pump, sufficiently examine the piping resistance.
●When the pump is installed in a suction manner, a viscous fluid may not be sucked due to increase in piping resistance. In the case of a viscous fluid, it is recommended to install the pump in a pushing manner.
●If the piping friction loss is large, reduce the piping length, or increase the piping diameter.
●The viscosity changes with temperature. Select a pump based on the viscosity at the working temperature.
●If the liquid to be flow has a high viscosity, see “Notes on transferring viscous fluid” for the selection of a pump.

A pump having a discharge flow rate of 45 ℓ/min is TD-20 (54 ℓ/min). Determine the intersection A of the total head of 18.21 m with a discharge flow rate of 45 ℓ/min from the performance curve of TD-20. The intersection A is on the left side of the performance curve of working pneumatic pressure of 0.7 MPa. This indicates that the pump meets the discharge flow rate with allowance.
❶Then, determine the required quantity of air. From the point B, draw a vertical line which intersects with the air consumption curves for 0.3 MPa and 0.5 MPa. The intersections are named point C and point D.
❷The intersection C with the curve for 0.3 MPa corresponds to the required amount of air of 150 ℓ/min, and the intersection D for 0.5 MPa corresponds to 260 ℓ/min. Therefore, the required amount of air at 0.4 MPa is 205 ℓ/min.
❸The number of cycles of diaphragm pump varies depending on the liquid temperature, viscosity and specific gravity. Select a compressor taking allowance of about 30% into account. The estimated capacity of compressor is 100 ℓ/min for 0.75 kW. In this case, 205×1.3=266.5 ℓ/min. Therefore, a compressor of 2.2 kW or more must be selected.

■How to read performance curve
Determination of model (bore)Example) Which model should be selected when the total
head is 10 m and the required discharge flow rate is30 ℓ/min? (Nitrile rubber diaphragms are used.)
Answer) ❶Multiply the required discharge flow rate by 1.5taking allowance for the pump into account. Discharge flow rate=required discharge flow rate×1.5
=30×1.5=45ℓ/min❷From the performance curve of TD-20, determinethe intersection of the total head of 10 m with adischarge flow rate of 45 ℓ/min.
❸The intersection is on the left side of theperformance curve for the working pneumaticpressure of 0.7 MPa. This indicates that the model meets the discharge flow rate with allowance.
❹As the result of the above examination, selectTD-20.
1. Fluid to be handled
2. Fluid temperature
3. Required flow rate
4. Heads and conditions
5. Air source
・ Fluid name ・ Concentration ・ Specific gravity ・ PH・ Liquid viscosity(at working temperature) ・ Inclusion of slurry, etc.
Pressure(MPa)・ air capacity(ℓ/min)〈ANR〉[or compressor output (kW)]
Note) If the fluid viscosity varies depending on the temperature,the piping resistance on the suction and discharge sideschanges, and, as a result, the discharge flow rate may change.

Operation
◆Make sure that the rated voltage of the product is identical to the AC power supply voltage. If they are not identical with each other, personal injury or fire may be caused.
◆Wire the pump in accordance with the electric maintenance engineering standards and internal wiring regulations. Failure to do so may cause burnout, electric shock, personal injury or fire.
◆The motor is not provided with a protective device. The electric maintenance engineering standards oblige to install an overload protective device. It is recommended to install a protective device (earth leakage circuit breaker, etc.) in addition to the overload protective device. Failure to do so may cause burnout, electric shock, personal injury or fire.
◆Connect the electric cable with a crimp-style terminal. Sufficiently insulate the connected parts with insulating tape.
◆When measuring the insulation resistance, do not touch any terminal. Failure to do so may cause electric shock.
◆Check that the product has been correctly installed and the mounting bolts are not loose. If the pump is operated with mounting bolts loosened, personal injury or damage to machines around the pump may be caused.
◆When the pump is used for an ignitable fluid, ground the pump using the supplied ground wire. If it is operated without grounding, a fire or an explosion may occur, resulting in personal injury or property damage.
◆Check that the pump has been wired correctly and surely. Failure to do so may cause burnout, electric shock, personal injury or fire.

Maintenance
◆During operation, never open the pump front plate to access or touch any internal rotating part. Your fingers may be involved with the part and injured.
◆If the power goes out, be sure to turn off the power switch. If operators are not aware of when the power comes back on, electric shock, personal injury or damage to the equipment may occur.
◆Do not operate the pump without the terminal box cover. It may cause electric shock.
◆When the discharge rate is controlled by adjusting the frequency, the allowable specified flow velocity at which the material is sucked into the pump varies depending on the material viscosity, specific gravity and suction head. If the specified flow velocity ratio is exceeded, the pump runs faster, the material causes cavitation, and the discharge rate decreases, thereby affecting the life of the diaphragms.
◆Adjust the flow rate with the inverter. Do not adjust it with a valve connected directly to the discharge piping. Never fully close the valves. During operation and before starting operation, check that the valves are open.
◆Use ETD2-2004*T-17 Series in the frequency range of 20 to 70 Hz, ETD2-2004*T-11 Series in the range of 30 to 70 Hz, ETD2-2507 Series in the range of 20 to 80 Hz and ETD2-2515 Series in the range of 20 to 100 Hz.
◆At a frequency from 20 to 60 Hz, use the pump at a current less than the motor rated current. At more than 60 Hz, use it within 90% of the rated current. Failure to do so may cause burnout, electric shock, personal injury and fire.
◆If the pump is kept stopped for a long time with a liquid containing slurry, the slurry will settle and deposit in the pump, and, when it is used next time, the diaphragms may be damaged or a bending torque may be generated on the disk to bend and break the cam ring. When the pump has been stopped for a long time, clean the inside to completely remove the slurry, and restart the pump. When the pump is not used for a long time, flush the pump with a solvent applicable to the material. Failure to do so may cause material deposition, thereby disabling the pump or significantly degrading its performance.
◆During operation, the motor is considerably hot. Take care that your hands or body do not get into contact with it, or you may burn yourself.
◆If any abnormality occurs, stop the pump. Failure to do so may cause burnout, personal injury or fire.
3. Checking in operating state
◆The pump shall be maintained by persons with sufficient knowledge and experience.
◆Never maintain or inspect the pump during operation. Doing so may cause injury accidents.
◆Do not maintain or inspect the pump with current on wires. Before working, be sure to disconnect power. Failure to do so may cause electric shock.
◆Tighten the bolts to the specified torque. If any bolt is tightened to a torque higher or lower than the specified torque, accidents may be caused by nonconformity or rupture.
◆Use our genuine replacement parts. If other manufacturers’ parts are used, the pump performance may be affected, or the pump may malfunction.
◆If the pump is kept used without maintenance, it may be damaged, machines around it may be broken, or personal injury may be caused.
◆We are not responsible for damage, accidents or failures in any case.
CAUTION◆Before lubricating the pump, disconnect the power. Failure to do so may cause personal injury.
◆When measuring the insulation resistance, take care not to touch any terminal. Failure to do so may cause electric shock.
◆During operation, the motor is considerably hot. Take care not to touch them with bare hands, or you may burn yourself.
◆To lubricate the pump, open the front plate. Periodically pour grease through the grease nipple.
◆As a lubricating grease, use Daphne Eponex EP-No.1 (Idemitsu Kosan) grease for high load or its equivalent.
◆The diaphragms, check balls and valve seats are wear parts. It is recommended to replace them when the specified number of times of operation is exceeded.
1. Daily inspection and maintenance
1) Inspection and time of replacement of diaphragmsThe estimated life of the diaphragms is approx. 10 million cycles of operation. (Note: This number of cycles is not a guaranteed value. Inspect and replace the diaphragms using this number as a guide. However, if the liquid contains particles, such as metallic particles, cuttings and hardwearing particles, which can damage them, their life will be reduced.)
<How to calculate time for replacement> (*Use the calculated time as a guide.)
Example) When Model EDT2-2004*T-17 is used at a frequency of 60 Hz (approx. 106 cycles/min) for operating time of 8 hours/day:
2) Time for replacement of check ballsIf the external diameter of the check balls (initial value: 20.6 mm or 39.4 mm) is reduced by 5% or more of the initial value or deformed, the contact between the check balls and the valve seats (sealing ability) is insufficient, and checking failure may occur. In such a case, replace the check balls.
3) Time for replacement of valve seats and cartridgeIf they are deformed due to wear, replace them. It is recommended to replace them when replacing the check balls.
4) RequestReplace the check balls and valve seats when replacing the diaphragms.

Discharge pulsation specific to diaphragm pump is absorbed, and more smooth discharge is realized.●The accumulators can be easily disassembled and reassembled without tools. (Man-hour for cleaning process is considerably reduced.)●They use a small number of parts and can be easily handled and maintained.●Transparent acrylic tubes through which the fluid in the accumulators can be visually seen can be manufactured as options. (Working pressure: 0.2 to 0.5 MPa)

Procedures for replenishing with air
●Install the accumulator in the vertical direction.●The piping to connect the diaphragm pump and the accumulator shall be as short as possible. Use a pipe having as large a diameter as possible. (Reduce the pressure loss caused by piping as low as possible.)●After piping, check for leakage from the connected parts.●Be sure to plug the unused ports.●When the accumulator is used for a long time, replenish it with air at regular intervals depending on the operating conditions.(If the amount of air in the accumulator is small, the pulsation absorber may not function properly.)●If the discharge pressure is low (e.g. when the head is low), the force-fed fluid does not enter the accumulator, and the pulsation absorber may not function properly. In this case, install a throttle valve on the piping on the discharge side (after the accumula-tor), and adjust the valve.
1)Reduce the pressure in the piping to the atmospheric pressure.
2)Discharge the fluid from the piping and accumulator.
3)Loosen the gauge plug to reduce the pressure in the accumulator to the atmospheric pressure.
4)Re-set the gauge plug, start the diaphragm pump, and check for air leakage.
