Explanation of Product Outline The metering pump PZiG Series accurately feeds a fixed amount of liquid for a fixed period of time. Liquid is fed by action of the check valve inside the pump head and volumetric changes in the pump head that occur by reciprocating motion of the diaphragm driven by the force of the electromagnet (solenoid). This structure ensures that the discharge volume per single operation of the pump is fixed. The pump can be used on a power supply within the voltage range 90 to 264 V.
Installation ! WARNING ¡This pump is not designed to explosion-proof specifications. It cannot be used in explosion-proof areas, and in explosive/ignitable atmospheres. ¡Install the pump in locations out of reach of personnel other than an administrator.
Piping This section mainly describes hose connection type piping. Contact TACMINA separately for details of other types of piping. Requests during Piping Installation ●Pulsation • The hoses on this pump vibrate as this pump generates pulsation. Secure this pump in such a way that hoses do not vibrate. • We recommend installing a damper to reduce pulsation. Contact TACMINA separately.

■Performance Curves The following performance curves are measurement examples obtained by measuring on test equipment at TACMINA. These performance curves may differ slightly depending on various on-site conditions and product differences. Measure the discharge volume under actual operating conditions, and set the strokes according to the performance curve that is obtained.
■Discharge Performance of High-viscosity Liquids ■Length of Discharge-side Piping and Discharge Volume When a fast stroke speed is set for transferring highviscosity liquids, piping resistance on the suction side may cause the amount of sucked in liquid to be reduced. The graph below shows the relationship between piping length and discharge volume. Installing a damper lessens piping resistance and allows the length of the piping to be extended.
