Overview
Overview
Introduction
Pump characteristics, features and part names are described in this sec-
tion.
Introduction
The TD series is the mechanically-driven diaphragm pump. Its pulse-reduction design en-
sures low ow pulsation without the need of an air chamber. A wide selection range of wet
ends allows for delivery of acid, alkaline, viscous liquid, slurry and solvent in various plants or
built-in applications.
Pump structure & Operating principle
Motor rotation is transmitted to an eccentric cam via a reduction gear and then converted to reciprocating
motion. Volumetric change occurs in the pump chamber as the diaphragm moves back and forth, so liquid is
delivered through the outlet with the assistance of the suction and discharge check valves.
Suction process
When the diaphragm moves back, negative pressure in the pump head opens the suction check valve to take
in liquid while closing the discharge check valve.
Discharge process
When the diaphragm moves forward, positive pressure in the pump head opens the discharge check valve to
deliver liquid while closing the suction check valve.

Pump mechanism
■ Flow pulsation reduction mechanism
The reduction mechanism consists of the two factors. One is the use of a highly-precise constant-velocity cam,
which makes a trapezoidal waveform of each discharge. The other is the phase shift of two different discharge,
The rear head moves out of phase with the front by 180 degrees to make a constant synthesized waveform.
The ow rate of the TD can change with a motor rotation speed (inverter frequency).
* Note suction pulsation is not reduced.
Constant-velocity cam and Phase shift
Discharge/Suction waveform
NOTE
The mechanically-driven diaphragm pump including the TD by its nature involves flow pulsation during op-
eration. The reduction mechanism can reduce but can't eliminate the pulsation completely, and the pulsation
becomes greater as a discharge pressure gets higher. This is because the diaphragm transiently depressed
under a high pressure as with every other mechanically-driven diaphragm pumps.

Installation
Installation
This section describes the installation of the pump, piping and wiring.
Read through this section before installation is performed.
Points to be observed
Observe the following points when installing the pump:
• Be sure to turn off power to stop the pump and related devices before installation is per-
formed.
• If you notice any abnormal or dangerous conditions, suspend operation immediately and
inspect/solve problems.
• Do not place explosive or ammable material near the pump.
• Do not use a pump that has been damaged to avoid the risk of electrical damage or
shock.
• Use care handling the pump. Do not drop. An impact may affect pump performance.
• Keep the pump as level and as low as possible when it must be lifted up.
• Fumes or vapours can be hazardous with certain solutions. Ensure proper ventilation at
the operation site.
• Observe information on the appropriate drawing and specification sheet.
Pump mounting
Before installation
Check if installation doesn't adversely affect facility, surrounding equipment and the pump. Install the pump ac-
cording to the following instructions to ensure the optimum performance, safety and service.
• Allow sufcient space around the pump for easy access and maintenance.
• Select a level location, free from vibration, that won't hold liquid. Always use a level gauge.
• Install the pump as close to a supply tank in a ooded suction system.
• Avoid installing the pump:
- In direct sunlight or wind & rain.
- In a dusty/humid place.
- In a corrosive atmosphere.
- In a place where proper ventilation is not maintained.

16 Pipework
Pipework
Pipework must be done according to the following instructions to ensure the optimum per-
formance, safety and service.
Piping layout
Arrange pump and pipework based on the following piping layout for a long period of operation.
NOTE
• Design an optimal layout to meet NPSHr, especially when planning to deliver slurry.
• If pipework directory weighs on the pump, the pump may be damaged. Be sure to install pipe supports.

Installation
Necessary devices
The following devices are needed to the metering pump. Be sure to install, or personal injury or property dam-
age may result.
■ Relief valve
The metering pump by nature keeps working, exceeding the limit pressure of discharge line if it is blocked. This
may damage the pump/piping system and burn out the motor. Install a relief valve close to the pump and x its
set pressure below the maximum allowable pressure of the pump/discharge line.
■ Back pressure valve
Discharge line pressure must be 0.03MPa or higher than suction line pressure. Otherwise, check valve may
not check ow and overfeeding may result. Install a back pressure valve on the discharge line to keep the mini-
mum pressure difference as necessary.
■ Strainer
Provide a 40-mesh strainer at the end of a suction line and clean it periodically. Otherwise, clogging may
result.
■ Pressure gauge
Install a pressure gauge to monitor the discharge line pressure.
Overfeeding is the condition that check valves in the pump head stay open and liquid continues flowing
into discharge line. Always keep the discharge line pressure 0.03MPa or higher than a suction line pres-
sure.

Pump inlet/outlet connections
Arrange the pump inlet and outlet according to a piping system in which the pump is incorporated.
■ Tube connection
Cut the tube ends at.
NOTE
Otherwise a leak may result.
Pass a tube into the tting nut and stopper and
then slide it down to the tube adapter as far as
it will go.
NOTE
The tube end must come within at least 2mm from the
bottom of the adapter.
Place an O ring into the inlet/outlet unit (part # 70/71).
Secure the tube end (with the tube adapter) on the inlet/outlet unit by hand-tightening the
tting nut.
NOTE
The plastic tting nut may be broken if tightened too much.
■ Union connection
Connect the union socket (72) to a plastic ange or joint of your piping system. Use an adhesive to secure the
connection.
NOTE
Do not allow an extra amount of adhesive to enter the pump.

Installation
Piping precautions
• Foreign matters such as sand and scale may enter pipework while service is performed. They may cause
fatal damage to the pump. Be sure to blow them out before operation. Also, do not apply adhesive too much
or leave a screw or nut.
• If pipework directory weighs on the pump, the pump may deform. Be sure to install pipe supports.
• Flange connection must be free from any tension or distortion, or a leak or pipe damage may result.
• The suction line I.D. should be equal to or wider than the I.D. of the pump inlet.
• Always keep the inlet of the pump below the liquid level of the supply tank (ooded suction).
• The pump suffers greater pressure loss as the piping length gets longer. Excessive piping resistance may
damage the pump depending on operating conditions such as liquid viscosity, liquid specic gravity and pip-
ing length. Contact us for detail.
■ Prohibited piping
P

Drain
Slurry delivery
The TD can deliver slurry with some limitations. Contact us for allowable particle size and concentration.
• Branch a drain line from the discharge line.
• Do not allow any inverted arch line in pipework where slurry can stay.
• Reduce (optimise) the suction and the discharge line I.D. as long as the NPSHr is satised in order to obtain
the maximum possible speed of ow.
• Install a ushing line (tap water) for removing slurry from the pump and piping after delivery.
• Do not use a back pressure valve. The valve may be damaged or clogged by slurry.
• With no use of a back pressure valve, the minimum differential pressure (0.03MPa or higher discharge pres-
sure than suction pressure) may not be satised and overfeeding may occur. In this case extend the dis-
charge line upwards to increase the pressure to the necessary level.
• If the relief valve has opened to release overpressure and been contaminated by slurry, take apart and clean
the inside to remove slurry.
• If an injection point at the end of discharge line is located at a lower position than a tank liquid level, siphon
will take place. In this case extend the rising part of discharge line over the liquid level and then separate the
falling part of it before the tank liquid level.
