Installation, Piping & Connections
WARNING
!
• This pump does not have explosion-proof specifications. Do not install it in explosion-proof regions or in explosive
or combustible atmospheres.
• Install the pump in a location that cannot be accessed by anyone but control personnel.
!
• If this pump has been dropped or damaged, consult your vender or a TACMINA representative. Using a dropped or
damaged pump may result in accidents and/or malfunctions.
• Do not install the pump where there is a risk of flooding or where there are high levels of moisture or dust. Doing so
may cause electric shocks and/or malfunctions.
• This pump has a water-proof construction (equivalent to IP65 under IEC standards). However, it is made of plastic
so make every attempt to avoid installing it in a position that will shorten its service life (such as a position where it
will be exposed to direct sunlight, wind or rain).
• Connect the pipes to the pump properly.
CAUTION
1
• Do not connect the pipes above a passageway. Do not install the pipes where the chemical may splash onto people
even if the hose/tube should break.
• When using a pump with a relief-valve function, always attach a hose for relief purposes, and lead the end of the
pipe back to a tank or other container.
• When using a pump without a relief-valve function, be absolutely sure to install a relief valve on the pipe right
outside the pump on the discharge side. If the user has forgotten to open the valve or foreign matter is clogged
inside the pump’s discharge-side pipe, this may cause the pressure to rise above the pump’s specifications range,
liquid to gush out, the pipes to become damaged and/or the pump to malfunction, all of which are dangerous.
• When using the pump in cold regions, the chemical may freeze inside the pump head or pipes, possibly damaging
the pump and its surroundings. Be absolutely sure to install a heating unit or heat-insulating unit.
• The water used for the shipment tests may be left on the liquid-end parts (the parts that come into contact with the
liquid) of the pump. If the pump is to be used for chemical that may harden or give off gas if it reacts with water, be
absolutely sure to dry off the liquid-end parts prior to use.
• When the hoses/tubes become very hot, their ability to withstand pressure will deteriorate. When using hoses/tubes
available on the market, be absolutely sure to use the ones which are resistant to chemical and which can withstand
the temperatures and pressures under which the pump will be used.
•
The durability of a hose/tube differs significantly depending on the chemicals with which it is used, on the temperatures
and pressures and on the presence of ultraviolet rays. Inspect the hoses/tubes, and replace them if they have deteriorated.
•
The control panel cover is made of plastic so do not subject it to excessive force. Otherwise, it may break or be damaged.
Electrical Wiring
!
• This pump cannot be used in explosion-proof regions or in explosive or combustible atmospheres.
• Take steps to ensure that the power will not be turned on during the course of work. Hang a sign on the power
switch indicating that work is in progress.
• Do not operate the pump with wet hands. Doing so may result in electric shocks.
• Securely ground the protective earth terminal, and be absolutely sure to install a ground fault circuit interrupter.
Otherwise, you may receive electric shocks.
• Do not attempt to disassemble the pump body or the circuit parts.
!
• The wiring must be done by a qualified electrician or somebody with electrical knowledge.
• Connect the wires after checking the supply voltage. Do not connect the wires to a power supply that is not within
the rated voltage range.
WARNING
CAUTION
Operation & Maintenance
!
• Ensure that nobody other than the operators and control personnel will operate the pump.
• Take steps to ensure that the power will not be turned on during the course of work. Hang a sign on the power

• Do not operate the pump with wet hands. Doing so may result in electric shocks.
• When trouble has occurred (such as when smoke appears or there is a smell of burning), shut down the pump’s
operation immediately, and contact your vender or a TACMINA representative. Otherwise, a fire, electric shocks and/
or malfunctions may result.
• Do not attempt to disassemble the pump body or the circuit parts.
• During the air releasing, chemical may suddenly gush out from the pipes and other parts. Lead the end of the airrelease hose bank to the tank or other container, and secure it so that it will not become disconnected.
• A situation in which the valve inside the pipe at the discharge side of the pump is shut off or becomes blocked
with foreign matter is dangerous in that it may lead to an excessive rise in pressure that will exceed the pump’s
specification range, causing liquid to gush out, the pipe to be damaged and the pump itself to malfunction. Prior to
operating the pump, check the valves and pipes, etc.
WARNING
CAUTION
!
• When working on the liquid-end parts of the pump, wear protective gear suited to the chemical concerned (such as
rubber gloves, a mask, protective goggles and work overalls that are resistant to chemical).
• Before attempting to maintain or repair the pump, release the pressure in the discharge pipe, discharge the liquid in
the pump head, and clean the liquid-end parts.
• The vibration of the pump may cause the hoses/tubes to become loose and disconnected. Before starting
operation, secure the hoses/tubes and check their tightness.
• While the pump is operating, the pump’s surfaces may become hot, reaching a temperature of 60°C or more.
• Idling the pump for prolonged periods of time can lead to malfunctions.
• When diluting sodium hypochlorite, use pure water or water processed with a water softener. Otherwise the pump
may malfunction or discharge trouble may result.

Installing the product
WARNING
!
• This pump does not have explosion-proof specifications. Do not install it in explosion-proof regions or
in explosive or combustible atmospheres.
• Install the pump in a location that cannot be accessed by anyone but control personnel.
!
• Do not install the pump where there is a risk of flooding or where there are high levels of moisture or
dust. Doing so may cause electric shocks and/or malfunctions.
• This pump has a water-proof construction (equivalent to IP65 under IEC standards). However, it is made
of plastic so make every attempt to avoid installing it in a position that will shorten its service life (such
as a position where it will be exposed to direct sunlight, wind or rain).
Installation
Installation location
• Avoid installing the pump in a location exposed to direct sunlight or wind and rain. Although it features a water-proof
construction (equivalent to IP65 under the IEC standards), direct sunlight may cause the temperature of the metal
parts to rise, ultraviolet rays may cause the plastic parts to deteriorate, and sand, dust, and rainwater may damage or
corrode the pump body. When installing the pump outdoors, it is recommended that an awning or cover be installed to
protect the pump from the elements and extend its service life.
• Install the pump in a location where the ventilation is good and where the chemical will not freeze.
• Provide adequate space around the pump to facilitate maintenance and inspections.
• Place the pump in a level location, and secure it so that it will not vibrate. Installing the pump at an angle may result in
discharge trouble or in the inability of pump to discharge.
CAUTION
Mounting bolt positions
Use the pump-mounting bolts (×2) provided to secure
the pump.
✽ Secure the pump in two places opposite each other
among the four possible places.
* The pump can be installed at any pitch ranging from
87 to 110 mm.
Assembling the pump
The direction in which the pump head and solenoid box
part (upper part) and circuit box part (lower part) are
assembled can be changed to one of three directions.

Installing the product
(1) Twist the pump head and solenoid-box part (upper part) counterclockwise by about 30 degrees, and lift slightly (by 2
to 3 cm).
✽ Check whether
the O-ring is
fitted into place
here.
(2) Twist the upper part in the desired direction, align the groove in the coupling of the upper part and the protrusion in
the coupling of the lower part, and insert.
(3) Twist the upper part clockwise, and secure.
IMPORTANT
•
The upper part and lower part are connected by wires. When lifting the upper part, lift it until the upper part and lower
part are separated just slightly (by a gap of 2 or 3 cm). The wires may be broken if the parts are separated too far.
• When twisting the upper part, do not apply pressure to the pump head and especially not to the joint
area and operation panel cover. Otherwise, the parts may be damaged.
•
The fixed part of the pump is made of plastic so refrain from applying excessive force to it. Doing so may damage it.
• Do not excessively twist the wires or pinch them between parts of the pump.
• The assembly directions are left, rear and right as seen from the control panel (only 90 degrees). The
pump cannot be assembled at any midway points.
•
During assembly, twist the upper part firmly until the protrusion touches the right end, and check that it is secured.

Installation
NOTE
• It is easier to twist the upper part if you press down on it.
•
When the pump is shipped, it is assembled so that the pump head is facing the left side as seen from the control panel.
Piping
Bear in mind the following points when connecting the pipes.
CAUTION
!
• Connect the pipes to the pump properly.
• Do not connect the pipes above a passageway. Do not install the pipes where the chemical may splash
onto people even if the hose/tube should break.
• When using a pump with a relief-valve function, always attach a hose for relief purposes, and lead the
end of the pipe back to a tank or other container.
• It is dangerous to operate a pump with the discharge side pipe closed off due to valve closing or
clogging with foreign matter, for example, because abnormal pressure will buildup inside the pipe. As a
safety measure, take the action in I or II, whichever is applicable.
I. When the pump is provided with a relief-valve function
Connect a relief hose to the air-release port, bring the end of the hose back to the chemical liquid tank
and secure it.
II. When the pump is not provided with a relief valve function
Attach a relief hose and relief valve to the discharge side pipe, and bring the end of the hose back to
the chemical liquid tank and secure it.
•
When using the pump in cold regions, the chemical may freeze inside the pump head or pipes, possibly
damaging the pump and its surroundings. Be absolutely sure to install a heating unit or heat-insulating unit.
•
When the hoses/tubes become very hot, their ability to withstand pressure will deteriorate. When using
hoses/tubes available on the market, be absolutely sure to use the ones which are resistant to chemical
and which can withstand the temperatures and pressures under which the pump will be used.
•
The durability of a hose/tube differs significantly depending on the chemicals with which it is used, on the temperatures
and pressures and on the presence of ultraviolet rays. Inspect the hoses/tubes, and replace them if they have deteriorated.
10
Piping
IMPORTANT
• Install a pressure gauge on the discharge-side pipe in order to measure the pressure at the discharge
side of the pump.
• Install the pump as close as possible to the tank. If the suction-side pipe is too long, cavitation* may
occur, possibly making it impossible to maintain the pump’s metering capability.
• Install a valve for releasing the pressure inside the discharge side pipe. The 3-way valve on the flushing
water line can be used instead.
• The intake performance may be reduced when the valve seat inside the pump head has dried out. If
liquid is not sucked in, moisten the valve seat with some liquid.
* Refer to the “Explanation of terms” on page 60.
■Pulsation
•
Installation
The occurrence of pulsation will cause the pump’s hoses/tubes to vibrate. Secure the hoses/tubes so that they will not swing about.
•
In order to reduce pulsation, the installation of a damper is recommended. Ask a TACMINA representative for more information.
■Pipe length
• An excessively long hose/tube may result in increased pressure loss, may cause the pressure to exceed the pump’s
allowable pressure, or may give rise to overfeed and/or cause pipe vibration.
•
The pump comes with a 3-meter-long hose/tube for both the discharge side and suction side. If the pressure loss exceeds
the pump’s maximum discharge pressure, thicker pipes will be required. Provide details on the (1) viscosity of the liquid, (2)
length of the pipes (how they are positioned) and (3) specific gravity of the liquid to a TACMINA representative.
■During maintenance
• When disconnecting the hose/tube for maintenance or other purposes and then reconnecting the same hose/tube, cut
about 10 mm off the end of the hose/tube before reconnecting.
• When conducting maintenance, release the pressure of the discharge hose/tube.
■When curving a hose/tube
• Provide a sufficient margin so that the hose/tube will not bend instead of curve round.
• Take steps to ensure that the hose/tube will not bend, rub against other parts, be cut or stepped on. Such actions can
damage the hose/tube.
• Take steps to minimize the number of tight curves in the pipes, joints and other parts that may restrict the flow.
Connecting
The piping procedure will be described by pump type.
✽ Pump above-tank mounting cannot be used for the DCLPW and high-viscosity type.
✽ If at all possible, use pump below-tank mounting position for the CLPW.
✽ When using the pump in an above-tank mounting position, moisten the valve seat area with some water or
chemical liquid before operating the pump.
✽ This pump has a maximum suction height of -1.5 m for water in the condition with the valve seat area mois-
tened. The suction capability may decrease when the valve seat area is dry. (Except the DCLPW, CLPW
and high-viscosity types)

• A thermal relay (TH) is used to protect against heat generation due to motor overload, which makes
it suitable for motor pumps or other equipment that are operated continuously, but it is unsuitable for
this solenoid-driven pump, which is operated non-continuously. In this case, the pump may not operate
properly.

Electrical wiring
There are two cable grounds, one for the power supply and one for the signals.
Connecting the power supply & protective earth
• A 3-pin detachable connector (including the protective
earth) is used to connect to the AC power supply.
• Use a round tough rubber-sheathed cable (VCTF-3C
or 4C) as the power cable.
✽ With the VCTF-4C, cut one of the wires.

Electrical wiring
External operation and stop input
The pump can be turned on and off using signals from an external device such as an interlock or level switch.
The pump runs or stops while (5) and (6) are shorted (no-voltage contacts) or while (5)+ and (6)- (open collector) are
input.
To set the operation to be performed when the external operation and stop input signals are received, refer to the settings list on page 32.
✽ The displayed settings blink while the pump is stopped by the stop input signal.
✽ If STOP has been selected, the pump will stop operating when the signal is input regardless of the setting.
✽ Even if OPERATION has been selected, the pump will not operate unless the external operation signal has been
input.
Signal input
Installation
● About signal input (SIGNAL IN) terminals
a) Input of non-voltage contact signal to a pulse input-type model
Non-voltage contact pulses produced by devices such as the pulse generator-type flow meter system are input to
terminal numbers (4) and (6). In this case, no considerations are required with regard to polarity. Be sure to use a
pulse signal that has low chattering noise. The contact points of a general control relay are not appropriate.
b) Input of open collector (drain) signal to a pulse input-type model
The electric current direction of the contact points of semiconductor devices (such as open collector and open
drain devices) is fixed due to the characteristics of these devices. Connect the collector (drain) to terminal number
(4) and the emitter (source) to number (6).
c) Input of electric current signal to an analog input-type model
Connect the signal wires (DC4 to 20mA) to terminal number (4) to use it as the positive terminal and to number
(6) to use it as the negative terminal.
● For details about signal specifications, see page 52.

Operating precautions
!
• Ensure that nobody other than the operators and control personnel will operate the pump.
• Do not operate the pump with wet hands. Doing so may result in electric shocks.
• When trouble has occurred (such as when smoke appears or there is a smell of burning), shut down the
pump’s operation immediately, and contact your vender or a TACMINA representative. Otherwise, a fire,
electric shocks and/or malfunctions may result.
• A situation in which the valve inside the pipe at the discharge side of the pump is shut off or becomes
blocked with foreign matter is dangerous in that it may lead to an excessive rise in pressure that will
exceed the pump’s specification range, causing liquid to gush out, the pipe to be damaged and the
pump itself to malfunction. Prior to operating the pump, check the valves and pipes, etc.
!
•
When working on the liquid-end parts of the pump, wear protective gear suited to the chemical concerned
(such as rubber gloves, a mask, protective goggles and work overalls that are resistant to chemical).
• The vibration of the pump may cause the hoses/tubes to become loose and disconnected. Before
starting operation, secure the hoses/tubes and check their tightness.
While the pump is operating, the pump’s surfaces may become hot, reaching a temperature of 60°C or more.
•
• Idling the pump for prolonged periods of time can lead to malfunctions.
• When diluting sodium hypochlorite, use pure water or water processed with a water softener. Otherwise
the pump may malfunction or discharge trouble may result.
Check the following points.

Check whether any liquid is leaking from the hole underneath the auxiliary ring at the back of the pump head.
Check the pressure gauge on the discharge side.
If liquid is leaking, it may mean that the diaphragm is damaged.
Inspect the diaphragm.
If liquid is leaking or there is a loose joint, replace or tighten it.
If liquid still leaks, inspect the O-rings in the joint concerned.
If the gauge shows an abnormal value, a pipe or
valve may be blocked.
Inspect the pipes.
