DESCRIPTION OF CHARACTERISTICS AND OPERATION
The "VP2-HT PH / RX" dosing pumps series are ideal for dosing acid and chlorine in small, medium and large pools.
They can operate in Manual, ON-OFF and Proportional mode and the flowrate is adjustable from 10% to 100% of the
maximum flowrate. They can adjust the flowrate by varying the rotation speed of the roll holder.
In standard version pumps it is possible to set a “delay on” switching on that allows to stabilize the measurement before
dosing and it is possible to set an overdose alarm (“TAL”).
Optionally, these pumps can be equipped with a peristaltic tube break sensor which, in case of chemical leaks, blocks the
dosage and they can optionally have a relay output, configurable for the repetition of an alarm (for example: flow alarm,
level, peristaltic hose breakage, etc).
THE FIRST THING TO DEFINE ON THE VP2-HT PH / RX PUMP IS IF THE PUMP MUST MEASURE PH OR RX.
