Solenoid-Driven Metering Pumps PZiG



Large-Volume Injection

A product lineup of four models up to 300 to 1000mL/min.

Can Be Used With High Viscosity Liquids

Also use for polymer coagulant injections.

  • *
    Transfer of high viscosity liquids may not reach the prescribed maximum discharge volume. To transfer high viscosity liquids, please contact us for application support.

Enter Injection Amounts Directly and Select From Three Patterns of Injection Amount Settings

Set by stroke speed

Setting range
1 to 300 strokes/min (can be set to 1 stroke/min)

Set by discharge amount

Setting range
From 0.1 (maximum discharge amount for selected model)/mL/min (can be set to 0.1mL/min)

Set by percent

Setting range
1 to 100% (for a maximum stroke count (300 strokes/min) of 100%, can be set per 1%)

Large Two-Row Display Panel With Backlight and Simple Operation Keys

Free Power Supply

100 to 240 VAC (±10%) operation means you do not need to worry about voltage fluctuations at the site. This pump can be used at a variety of locations and for a variety of purposes.

Water-Resistant, Dustproof Construction

IEC standard
IP65 equivalent

An Array of Wetted Part Materials to Handle a Wide Variety of Chemicals and Uses

  • *
    Stainless steel types (SS304/316) are also available by special order.

Simple Correction to Actual Discharge Amount

Simple correction function to automatically discharge 300 strokes of chemicals. Just enter the discharge amount into this device to use the actual flow amount for an easy and accurate correction.

Analog Input Proportional Control

Injection amount (stroke speed: 0 to 300 strokes/min) can be set based on analog input signals (4 to 20 mA) from an external source to control pH, residual chlorine and a wide variety of other uses.

Motor Driven Pump Inverter required Narrow control range of 1:10(6 to 60 Hz) Raw liquid must be diluted since the discharge volume per stroke is large. PZiG Inverter not required Wide control range of 1:300(1 to 300 strokes/min) Raw liquid can be injected since the discharge volume per stroke is small.

Pulse Input Proportional Control and Stop Input Control From Outside

Not only can the pump ON/OFF be controlled via an external input, injection amount (1/9999 to 9999 strokes/pulse) can also be set based on pulse input signals. Interlocking with a pulse-emitting flow meter or level measurement enables simple execution of a variety of simple automatic controls.

Two-Point Control of Level Measurements

Control alarm display and generation, pump stop and other controls based on the amount of chemicals remaining in the tank.
