Pump Solutions Group Neptune Series PZ_PZi_PZiG Pulse Metering Pumps - Manual (Page 5)

• 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.
• Connect the flow checker output to your
controller or PLC (external power supply
required if not used with PZi8 type pump).

CAUTION – ALL MODELS
• Ambient temperature: 32 to 104°F (0 to 40°C)
Pumped liquids:
Temperature: 32 to 104°F (0 to 40°C),
Viscosity: 100 CPS max. except as noted
• This pump is designed for outdoor use. Avoid
installing pump in a location where service life
could be shortened (i.e., where it is exposed to
direct sunlight or driving rain).
• This pump cannot pump liquids containing a slurry.
• A relief valve should be installed on the discharge
side, if the pump does not have a built-in relief
valve and the discharge piping has a shutoff valve.
