NOTES: 1. PZi4 and PZi8 Models in sizes -31/-61 /-12: 50% to 100% stroke length adjustment.
PZi4 and PZi8 Models in sizes -32/-52 plus all PZD and PZiG Models: 20% to 100% stroke length adjustment.
2. PZi8 only when used with Flow Checker shown on page 5.
3. PZi4 has one analog input and one high speed digital pulse input; PZi8 and PZiG have one analog input and two high speed digital pulse inputs. See page 9.
4. Two separate configurable outputs, either open collector (alarm, error, run) or pulse (operational sync or end of cycle).
5. Sizes -31 /-61/ -12 only.

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
