Advantages

• Better accuracy with low flow rate injection starting at 0.002 gph (0.1ml per minute)
• Digital settings from 0 to 300 pulses per minute
• High stroking speed ensures more uniform distribution of chemical at low feed rates
• Worlds first* wide voltage range power supply (AC90 to 264V); all models operate on any single phase voltage from 94 VAC to 264 VAC
• Pump can be installed outside; no pump cover is needed (equivalent to IEC specification, IP65)
• Pump head rotates to three different positions in 90 degree increments; can easily be fitted into piping and equipment

PZ Series

Electronic Pump Systems

Applications

• Injection of chemicals to boilers and cooling towers
• Chlorine sterilization for food plants, small-scale water-supply systems, buildings and swimming pools
• Injection of nutrients and disinfectants in the livestock industry, such as poultry and hog producers, as well as for hydroponic cultivation
• Very low flow rate injection of low viscosity liquids for any application (100 CPS max.)

Superior Engineering

• Liquid ends designed for any chemical
• Double check valve configuration on suction and discharge
• High compression head and diaphragm
• Integrated air release valve.
• Great look and rugged feel.

Model FC-1 FLOW CHECKER

The Model FC-1 Flow checker output provides vital information for water treatment programs requiring feed verification to manage chemistry and monitor drum inventory.

• The flow checker mounts directly to the discharge of PZ and PZi metering pumps.
• The flow checker is an oval gear flow meter which measures the pump output and
• transmits one pulse for each 1 ml of flow.
• Flow checker output can be connected to Model PZi8 Pumps for instantaneous indication of pump output displayed on
• the pump LCD. The flow checker output can also be connected to a Neptune Model FLC100-B Flow Indicator–Totalizer,
• to display both instantaneous flow and totalized flow.
• Connect the flow checker output to your controller or PLC.

Model PZiA

Automatic Flow Control Electronic Metering Pump

Features

• Built-in calibration
• Maintains precise feed rate by correcting for changes in pressure/viscosity
• Precise batch injection

PZiA Electronic Metering Pumps are the first in the world to feature an integrated automatic discharge volume control. Special circuitry allows onboard calibration of pump flow under actual process conditions. Each PZiA is furnished with a Flow Checker for feed verification and a constant pressure valve for the best possible accuracy.

Once calibrated, the pump can be manually set or can be controlled by an analog signal. The pump then automatically adjusts by increasing or decreasing the stroking speed to maintain the precise flow rate regardless of changes in temperature, pressure, or viscosity. PZiA pump accuracy has been verified by KEMA.
