1. Introduction
1.1 AMS Series AMS metering pumps are the ideal solution for low / middle dosing of chemicals.
Flow rate is determined by the stroke length and by the stroke speed. The stroke length is adjustable from 0 to
100% using the stroke length adjustment knob. However dosing accuracy is guarantee within an adjustment
range from 30% to 100%.
1.2 AMSA Series AMSA is the AMS version with self-venting pump head.
Self-venting pump head must be used when using chemicals that produce gas (i.e. hydrogen peroxide, ammonium,
sodium hypoclorite at particular conditions).
For connections

1.3 AMS AC Series AMS AC is the AMS version with double supply: compressed air and power supply. Compressed air without
lubrifiant and/or condensed water. Air supply pressure range must be from 6 to 10 bar.
For connections

Each series is available in different models:
SERIES MODEL HOW DOES IT WORK
AMS AMSA AMS AC CO Constant pump with stroke speed (frequency) adjustment
AMS AMSA AMS AC CL
Constant pump with level control, stroke speed (frequency)
adjustment
AMS AMSA - IS
Constant-proportional pump driven by external digital signal with
level control: to each external pulse correspond one pump stroke
AMS AMSA - PV
Constant-proportional pump driven by external digital signal with
pulse divider mode (ratio 1 to 1000) and level control
AMS AMSA - PVM
Constant-proportional pump driven by external digital signal, level
control , with pulse divider mode (ratio 1 to 100) and multiplier
mode (ratio 1 to 10)
AMS AMSA - IC
Constant-proportional pump driven by current signal (0/4mA = 0
pulses; 20mA = max pulses) and level control
