MODEL NUMBER SELECTION–
The complete model number consists of three parts: TYPE + SIZE + MATERIAL CODE
TYPE – Specify PZ or PZD for manual control; specify PZi4 for external input; specify PZi8 for programmable models.
The largest models are the PZiG Series, available in full programmable type only.
SIZE – Size code selects the capacities per the charts on page 3. Sizes -31, -61 and -12 are available for type PZ.
Higher capacity sizes -32 and -52 are available for type PZD. All five sizes are available for types PZi4 and PZi8. The very high PZiG capacities are shown in a separate chart.
MATERIAL CODE – Select from charts on page 4.
Example – The complete model for a pump with a Kynar liquid end with Viton seals rated at 160 ml/min capable of accepting a 4-20mA input would be:
Type PZi4 + Size -61 + Material code -FFC
The complete model number becomes
PZi4-61-FFC

Type PZD /PZi-32 /52 High Capacity Models
PZD Series pumps offer higher capacities. These models feature an extra large keyboard and the injection rate can be entered directly in milliliters per minute.
The injection rate can be set three ways by direct entry of:
– Stroke speed: 1 to 300 spm – Percentage: 1 to 100% – Injection rate: ml/min.
Onboard calibration measures the

actual discharge volume under the exact operating condition of the specific installation and chemical, then stores that value to insure the correct injection rate.
Type PZiG Programmable Large Volume Models
PZiG Models offer capacities typically requiring motor driven pumps. Special models easily handle viscosities of 1000 CPS (up to 4000 CPS at reduced volume).
Powerful onboard controls allow proportional flow rate, pH and residual chlorine control by direct analog connection eliminating the PID Controller and Inverter (plus the control panel to house them), that are required by similar sized motor driven pumps.
The injection rate can be set three ways by direct entry of:
– Stroke speed: 1 to 300 spm – Percentage: 1 to 100% – Injection rate: ml/min.
• Manual stroke length adjustment 20% to 100%.
Control Functions also include (see pages 8 & 9):
Onboard calibration measures the actual discharge volume under the exact operating condition of the specific installation and chemical, then stores that value to insure the correct injection rate.
• Multi-pump proportional flow rate injection from a single direct flowmeter signal (pulse/analog).
• Two point level switch control (see page 9)
Note: Install a pulsation dampener for discharge lines greater than 7 feet to achieve maximum pressure capability.

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.
(shown with
PZi8 type
pump)
• Flow checker output can be connected to Model PZi8 Pumps for instantaneous indication

Advantages
Digital settings from 15 to
• 300 pulses per minute on PZ models and from 1 to 300 pulses per minute on PZi and PZD models
• High stroking speed ensures more uniform distribution of chemical at low feed rates
• Pump delivery is constant at any voltage from 94 to 264 VAC single phase and is not affected by voltage fluctuations
• Outdoor use—pump is water and UV resistant. Equivalent to IEC specification IP65. Dust proof, wash down duty (with proper electrical connection).
Cross Sectional view applies to PVC, Kynar and Type CL Heads; does not apply to Material Codes ARPZ, SS or any PZiG Liquid Heads.
ome models use single check balls.
S
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. except high viscosity models)
ANALOG SIGNAL INPUT

The proportional band can be adjusted within a range of ±1% to ±999%. Pump response to increasing input signal is easily reversed from min. 4mA
and max. flow at 20mA to max. flow 20mA and min. flow at 4mA. 0mA to 20mA range on PZi8 models.

Programmable Models PZi8 & PZiG Control System Examples
YOUR SYSTEM IS ENHANCED BY OUTSTANDING CONTROLLABILITY
Proportional Flow Rate Control – Models PZi8 & PZiG
Flow meter signals are received directly according to the flow rate of the main piping and the discharge volume is automatically controlled.
Advantage
This eliminates the need for control devices, which have been needed up until now, and reduces the cost of devices.
Cost benefits: Digital panel meters, PID controllers and inverters are no longer required.
Advantage
pH Control – Model PZiG only
Control signals from the pH meter are received and chemicals are automatically injected according to the preset pH value.This simplifies the configuration of the control devices.
Cost benefits: Two PID controllers and two inverters are no longer required.
Advantage
Sterilization – Model PZiG only
Automatic control is possible on the pump unit merely by receiving signals directly from the residual chlorine meter and setting the target residual chlorine value.
Cost benefits: Control panels (PID controllers and inverters) are no longer required.
