Available Only in Programmable Models
(See page 8 for Direct Connection of pH and Residual Chlorine Control Instruments)
Type PZiG Programmable Large Volume 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.
High Capacity models are
available in material codes
VFC, VEC, SS and FTC only.
VFC model is shown.

Liquid Head
• Manual stroke length adjustment
20% to 100%.
• Set points can be easily viewed
on the LCD.
• Pump head may be rotated to
face in any of the three positions
other than where the keypad
and display are located.
• Pump head can be decoupled
from the controller base for
remote mounting.
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.
• Batch injection • Interval injection
• Proportional control with shift and proportional band function.
• Two line LCD screen displays injection rate and/or operational progress.
