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.
