3.3.4 How to choose the pump
As the number of m
3
of water to be treated in the system is known, and the quantity of product to be dosed,
expressed in P.P.M. (parts per million) it is possible to define the
minimum hourly capacity of the dosing pump
required, using the following formula:
L/H
flow of the HC150 PI pump.
PPM quantity of product to dose (gr/m
3
).
K
concentration of the chemical product to dose (pure product K=1).
Example: Sodium hypochlorite at 12%; K = 100:12 = 8.3.
m
3
maximum flow of the water to be treated expressed in m
3
/ H.
3.3.5 How to set the “N” parameter in 1/N mode
To identify the value of N (position of the knob) proceed as follows:
N
number to set on the HC150 PI pump.
pul/L
pulses per litre provided by the counter.
cc
quantity of product dosed per single injection (expressed in cc) of the pump.
PPM quantity of product to dose (gr/m
3
).
K
concentration of the chemical product to dose (pure product K=1).
If in the calculation the "N" parameter is:
N<1 (N less than 1) it is necessary to install a counter with a number higher than the number of pulses per
litre or a pump with a greater capacity per injection.
N>1000 (N greater thasn1000) it is necessary to install a pump with a lower capacity per injection.
When setting the "N" parameter remember that when the knob is at its maximum it corresponds to
the lowest N value of the selected interval.
