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.

• 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.

CAUTION

Page 3

• 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.

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 switch indicating that work is in progress.

• 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.

Other Precautions

CAUTION

• Do not attempt to remodel the pump.

• Install a protective barrier or other preventive action to cope with a chemical spill just in case one occurs. Also take steps to ensure that the pump will not get wet from the chemical.

• When it comes time to dispose of the pump, entrust its disposal to an industrial waste disposal company whose operations have been authorized in accordance with applicable laws and regulations.

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).

CAUTION

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.

Installation

Mounting bolt positions

Use the pump-mounting bolts (×2) provided to secure the pump. ✽ The pump can be installed at any pitch ranging from 87 to 110 mm.

Page 10

Piping

• 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.

•

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.

•

Installation

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.

•

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.

* Refer to the “Explanation of terms” on page 53.

CAUTION

■Pulsation

• 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 5-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.

The piping procedure will be described by pump type.

Installation is described with an example using PZ-31-VEC and TACMINA tank.

• If the valve has not been opened or clogging by foreign matter has occurred inside the pipe at the discharge side of the pump, the chemical will gush out from the relief/air-release port. Therefore, always have a relief/air-release hose installed, and lead its end back into the tank or other container.

• Install a valve for releasing abnormal pressure that has built up inside the discharge-side pipe. The 3-way valve on the washing water line may be used instead.

■ When installing the pump

below the tank

(1)

Connect the suction valve of the tank and the suctionside joint of the pump using the hose/tube.

(2) Connect the discharge-side joint of the pump and

main pipe (injection point) using the tube. When doing this, attach the anti-siphon check valve at the injection-point side end of the tube.

(3) Return the end of the relief/air-release hose which

has already been attached to the relief/air-release port to the tank or other container.

✽ It is also recommended that a valve, meter, etc. be

installed to make it easy to carry out maintenance and other such jobs.

■ When installing the pump

above the tank

(1) Using the pump-mounting bolts provided, secure the

pump to the prescribed position on top of the tank.

(2) Pass the suction-side hose/tube with foot valve and

ceramic weight (tube only) attached through the hole in the suction-pipe cover on top of the tank, and connect it to the suction-side joint of the pump. At this time, adjust the length of the hose/tube and cut it so that the foot valve is 30 mm higher than the bottom of the tank.

(3) Connect the discharge-side joint of the pump and

main pipe (injection point) using the tube. When doing this, attach the anti-siphon check valve at the injection-point side end of the tube.

(4) Return the end of the relief/air-release hose which

has already been attached to the relief/air-release port to the tank or other container.

✽ Installing the pump above the tank is not recommend-

ed for chemicals in which air bubbles tend to form.

✽ This pump’s static suction head is −1.5 m for water.

Its suction capability may decrease when the valve seats inside the pump head are dry.

✽ Be absolutely sure to connect the foot valve provided

to the end of the suction-side hose/tube to prevent dirt or foreign matter from entering the pump head and valve seat area.

✽ It is also recommended that a valve, meter, etc. be

Model for injection of sodium hypochlorite: PZ-31/61/12-CL

Installation is described with an example using PZ-31-CL and TACMINA tank.

• It is extremely dangerous for the user to forget to open the valve or for there to be the clogging of foreign matter inside

the pump’s discharge-side pipe. Be absolutely sure to install a relief valve, which will automatically release abnormally high pressure levels, on the discharge-side pipe.

• Install a valve for releasing abnormal pressure that has built up inside the discharge-side pipe. The 3-way valve on the

washing water line may be used instead.

• To prevent gas lock and other such types of trouble, be absolutely sure to use the pump with a push-in pipe (when the

pump is to be placed lower than the tank).

• In order to prevent gas lock caused by gases generated and building up inside the pipes, make the pipe connections

as short as possible.

■ When installing the pump

below the tank

✽ Do not install the pump above the tank. (1)

Connect the suction valve of the tank and the suctionside joint of the pump using the hose. When doing this, tilt the pipe at a downward gradient so that no air will be trapped inside the pipe.

(2) Connect the tube to the discharge-side joint of the

pump.

(3) Attach a 3-way joint to the discharge-side tube (near

the pump’s discharge-side joint), and install a relief valve. Return the end of the relief pipe to the tank or other container.

(4) Connect the end of the other discharge-side tube

extending from the 3-way joint to the main pipe (injection point). When doing this, attach the antisiphon check valve with duck-bill cap at the injection-point side end of the tube.

(5) Attach one end of the air-release hose to the air-

release port, and return the other end to the tank or other container.

✽ If it is unavoidable for the pump to be placed higher

than the tank, be absolutely sure to connect the foot valve supplied to the end of the suction-side hose to ensure that no dirt or foreign matter will be mixed inside the pump head or valve seat.

✽ It is also recommended that a valve, meter, etc. be

installed to make it easy to carry out maintenance and other such jobs.

(5) Attach one end of the air-release hose to the air-

release port, and return the other end to the tank or other container.

✽ If it is unavoidable for the pump to be placed higher

than the tank, be absolutely sure to connect the foot valve supplied to the end of the suction-side hose to ensure that no dirt or foreign matter will be mixed inside the pump head or valve seat.

✽ It is also recommended that a valve, meter, etc. be

installed to make it easy to carry out maintenance and other such jobs.

• When bending the hose/tube, provide sufficient leeway in the bending so that the hose/tube will not break. Also ensure that it will not be rubbed against or trodden on.

• Insert the hose/tube firmly so that it will not become disconnected, and tighten the nuts securely. Do not excessively tighten the nuts. Doing so may damage or break the joint.

• If the temperature of a liquid or ambient temperature is higher than room temperature, the tightening force will be reduced, and the hose/tube may become disconnected. After operation has started, tighten up the nuts as appropriate.

• When tightening the nuts, hold the hose/tube to prevent it from being twisted. The joints and other areas may be loosened by the return force of the hose/tube.

• The pump comes with a 5-meter long hose/tube for both the discharge side and suction side. When longer hose/tube is used, the pressure loss may exceed the pump’s maximum discharge pressure so thicker hose/tube 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 who will select the appropriate hose/tube size.

• When disconnecting the hose/tube for jobs such as maintenance and then afterwards re-connecting the same hose/ tube, cut about 10 mm off the end of the hose/tube before re-using them.

■Anti-siphon check valve

This pump is provided with an anti-siphon check valve. Use this valve at the injection point unless there is a good reason not to do so. Be absolutely sure to install it in the following cases.

• When the injection point is open to the atmosphere and liquid is to be injected at a position lower than the level of the liquid in the tank (prevention of siphoning)

• When the liquid is to be injected inside the suction-side pipe of a volute pump, etc.

• When a chemical greatly exceeding the pump’s rated discharge volume is being fed (prevention of overfeed) ✽ Even with a rising pipe, overfeed may occur if the pipe is too long.

(1) The anti-siphon check valve has an R1/2 external thread. Provide an Rc1/2 internal thread at the injection point.

Installation

(2)

Wind sealing tape around the external thread of the anti-siphon check valve, and screw the valve into the injection point.

✽ If it is hard to screw the valve in, grasp the nozzle grip using a tool such as pliers, and tighten the valve gently. ✽ When connecting the tube with the anti-siphon check valve already mounted on it to the main pipe, be absolutely

sure to hold the valve body and turn the nut. If the nut is turned without holding the body, the threaded part on the nozzle may be damaged.

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).

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.

WARNING

CAUTION

Check whether the amount of liquid is sufficient. If it is not, replenish it.

Check whether any pipes have become disconnected or damaged. If so, re-connect or make repairs.

Check that the valves are open. If a valve is closed, open it.

Check that the pump is connected properly to the prescribed power supply.

Take special care in cases where the chemicals or processes involved would be adversely affected if air were sucked in.

−

Closed valves can cause dangerous situations in which the pressure rises excessively, liquid gushes out and/or the pipes are damaged.

If it is not, the electronic circuits and solenoids may burn out.

Operation

Procedure for prolonged shutdown of operation

Follow the steps below when shutting down the pump for a prolonged period.

To shut down the pump

(1) Operate the pump so that clean water or cleaning fluid is sucked in and discharged for about 30 minutes to

clean the inside of the pump head. (2) Turn off the power completely. (3) Place the cover over the pump to protect the pump from the build-up of dust and corrosive environments.

To resume operation

(1) Check the inside of the tank for any sediment that may have accumulated, and check for signs of trouble such

as cloudy liquid. If the liquid quality has deteriorated, clean the inside of the tank, and replace all the existing

liquid with fresh chemical. (2) Check the valve seat areas and check balls inside the joints for dirt and other foreign matter. (3) Check the items in the section “Before operation” on page 25.

Page 30

Maintenance precautions

• 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 switch indicating that work is in progress.

• 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.

• 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.

Check the following points.

WARNING

Replacing the relief valve

✽ This instruction is described with an example using PZ-31 (VEC type).

IMPORTANT

Take the following action when the relief-valve function has been activated by clogging of the dischargeside pipe, for instance.

• Shut down the pump immediately, remove the cause of the trouble, and take steps to prevent its recurrence.

• The relief valve is a consumable. Replace it once it has been activated.

Replacing the relief valve

(1) Hold the retaining nut (the part shown by the arrow), and turn it counterclockwise.

(2) Check the O-ring of the new relief valve for dirt or foreign matter.

✽ The large O-ring comes coated with fluorine-based grease. Use it as is.

Maintenance

(3) Hold the retaining nut (the part shown by the arrow), turn it clockwise, and install it on the pump head.

(4) After installing the relief valve, rotate the air-release knob by two turns in the clockwise direction to ensure that the

O-ring is seated properly.

O-ring (large) ✽ Coated with fluorine-based grease.

Troubleshooting

• 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 switch indicating that work is in progress.

• 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 relief/air-release 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.

• 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.

WARNING

CAUTION

NOTE

• Use of a flow indicator is recommended as a method to detect discharge trouble. ✽ Refer to “Spare parts & options” on page 53.

Consumables

• Failure to replace the consumables may cause discharge (or injection) trouble and/or malfunctions.

• The replacement timeframes of the consumables have been determined under the prescribed conditions (clean water, room temperature) prevailing at TACMINA’s test facilities.

• Since these timeframes will differ under the individual conditions prevailing on-site, use them as a general guide, and replace the consumables at an earlier rather than later date.

CAUTION

• 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.

NOTE

• TACMINA will continue to supply consumables for its pumps for a period of eight (8) years after the manufacture of the pumps has been discontinued.

• “Parts kits” consisting of a complete set of consumables are available (except for some models).

For details on how to replace the consumables, refer to “Replacing the diaphragm”, “Replacing the valve seats and check balls” and” Replacing the relief valve” (on page 30 to 35).

Spare parts & options

■Spare parts

• Nuts • Retaining rings • Joints • Air-release nozzles

■Options

• Back pressure valve

This valve prevents overfeeding* applying just the right amount of pressure (back pressure) to suppress the in-ertia force of the fluid.

• Relief valve

This valve automatically releases abnormal pressure that occurs in the discharge-side piping, due to blockage by foreign objects and tightening of the valve, to prevent accidents or possible damage to the pump and piping.

• Air chamber

Reciprocating pumps may develop pulsation, which causes pipe vibration and overfeed. If this is the case, use of an air chamber can regulate the chemical into a more continuous flow and alleviate the various problems associated with pulsation. When an air chamber is to be installed, be absolutely sure to provide the relief valve mentioned above.

• Accumulator

The accumulator is provided to reduce pulsation, and the principle behind its operation is the same as that of the air chamber. It is effective at high pressure levels above 0.5 MPa and when using liquids that are affected by air.

• Level Switch

This sensor detects the low chemical level in the tank. Two models, a 1-point (single-sensor) and a 2-point (doublesensor) model, are available.

• Flow checker

This highly acid- and alkali-resistant, low-cost flow meter allows you to monitor injection operation of the pump. It can be directly attached on the discharge side of the pump.

• Flow indicator

The discharge operation can be monitored at a glance by attaching this indicator at the discharge side of the pump. It also helps to prevent injection trouble.

• Deforming joint

Installed on the suction side of the pump, this joint separates air bubbles and fluid to prevent air bubbles from entering the pump head.

• PTU-25/50/100

These are chemical injection units consisting of a metering pump and PE tank (with a capacity of 25, 50 or 100 liters).

• Chemical tank

Tanks made of PE (with a capacity ranging from 25 to 100 liters) or of PVC (with a capacity ranging from 100 to 1,000 liters)

• Solution tank

These tanks (made of PE with a capacity ranging from 50 to 500 liters) can have a metering pump or agitator mounted on top.

• Parts kit

This kit contains a complete set of all required consumables.It is economical, and an easy way to store and managethe parts you need.

and siphoning*2 phenomena by sealing the chemical outlet with a diaphragm and

Explanation of terms

• Overfeed

The phenomenon that the force (inertia) of the discharge during chemical flow with pulsation causes chemicals to continue flowing when chemical flow should stop, resulting in excessive chemical discharge beyond the specified vol-

ume.

• Siphoning

The phenomenon that chemicals continue to be sucked out naturally and continue flowing when the tip of the pump's discharge-side piping is lower than the level of liquid in the suction-side tank.

• Cavitation

This phenomenon that the negative pressure inside the pump head causes air bubbles to form, diminishing the discharge volume and causing abnormal noises and vibration.

✽ For more detailed information, ask for “How to use metering pumps properly,” a technical document provided by

TACMINA.
