Solenoid-driven Diaphragm Metering Pump PZ Series OPERATION MANUAL Please read this OPERATION MANUAL carefully before use. Operating the pump incorrectly in disregard of these instructions may lead to death, injury and/or cause property damage. Applicable Models PZ-31/61/12 ARPZ-31/61/12 This illustration is for PZ-31 7Thank you for purchasing this TACMINA product. Please read this OPERATION MANUAL carefully in order to ensure that you will use the product safely and correctly.
How to operate the pump safely In order to ensure that the pump will be operated correctly and safely, this OPERATION MANUAL contains some guidelines for the user in the form of important safety precautions and considerations which, depending on their seriousness, are categorized as set forth below. Be absolutely sure to heed these precautions and considerations.
• 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.

Introduction Description of product This is a solenoid-driven diaphragm metering pump with liquid-end parts which are resistant to chemicals and with a compact body. It can be operated on any supply voltage from AC 100V to AC 240V (±10%). Its discharge capacity has been adjusted so that it will remain constant over the supply voltage range.
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. CAUTION • 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.
Piping Installation ! 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.
Piping Model for injection of general chemicals: PZ-31/61/12-VEC/VFC/FEC/FFC/FTC ■When installing the pump below the tank Injection point (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.
Piping Model for injection of boiler chemicals: PZ-31-FEC (PP) Installation Installation is described with an example using PZ-31-FEC (PP) 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.
Piping 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.
Piping Installation Model w/ automatic air-release function for injection of sodium hypochlorite: ARPZ-31/61/12 Installation is described with an example using ARPZ-31 and TACMINA tank. • Unlike other models, this pump has a discharge-side joint at the front of the pump head and an air-release side joint on its top. • 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.

Connecting ■Anti-siphon check valve Installation 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.
Connecting Model for injection of general chemicals: PZ-31/61/12-FEC/FFC/FTC • When bending the tube, provide sufficient leeway in the bending so that the tube will not break. Also ensure that it will not be rubbed against or trodden on. • Insert the 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.

Also ensure that it will not be rubbed against or trodden on.
Connecting ■Anti-siphon check valve w/ duck-bill cap (1) The anti-siphon check valve with duck-bill cap has an R1/2 external thread. Provide an Rc1/2 internal thread at the injection point. (2) Wind sealing tape around the external thread of the anti-siphon check valve with duck-bill cap, 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.
Electrical wiring ! WARNING ! CAUTION • 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. Power cable (2m) is already attached. Example of wiring ●When operating the pump in tandem with an irrigation pump, etc.

Operating precautions ! WARNING • 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.
Air releasing ! WARNING • 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. IMPORTANT • When using the pump for the first time or when the chemical container has been replaced, proceed with the task of air releasing prior to operating the pump.
Air releasing Model for injection of sodium hypochlorite: PZ-31/61/12-CL (1) Insert the air-release hose provided into the air-release port. (2) Return the other end of the air-release hose to the tank or other container, and secure it firmly. Airrelease port Operation Air-release hose (3) Turn off the pump’s power, and release the pressure inside the discharge-side pipe. (4) Set the discharge volume to the maximum level. (See page 28) (5) Turn on the pump’s power to start operating the pump.

If this happens, adjust the dial again.
Maintenance precautions ! WARNING • 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.
Replacing the diaphragm ✽ This instruction is described with an example using PZ-31 (VEC type). IMPORTANT • When securing the pump head using the head bolts, tighten them up evenly a little at a time in the sequence shown in the figure on the right. If, for instance, the bolts are tightened up in the sequence of 1 → 3 → 2 → 4, the bolts will be tightened unevenly, possibly causing the chemical to leak from the pump head. 1 3 4 2 Removing the diaphragm (1) Remove the head bolts.
Replacing the valve seats and check balls IMPORTANT • Install the parts in the correct sequence and correct directions. • Pay special attention to the sequence and directions for the joints and valve seat assemblies. • Check the O-ring, check balls and valve seats for damage and dirt.
