- Connect the pump to the plant always through the injection valve (1/2"Gm)
supplied with the installation kit.
- Connect the soft PVC tubing only in suction (on the foot filter side), instead
connect the PE tubing in delivery by verifying that the cut of the tubing is
clean and that lateral crushing is not caused; it is advisable to utilise a
cutter instead of scissors.
2.6 Operation
The metering pump is activated by a Teflon diaphragm mounted on a piston enclosed into a
electromagnet, which is fed by continuous current producing a square wave moving the piston
thus, a pressure is produced in the pump body with an expulsion of liquid from the discharge
valve. Once the electric impulse is over, the return of the piston is spring assisted thus producing
the suction action to the initial position, with a recall of liquid through the suction valve. The
material used for the construction of the pump makes it particularly suitable for aggressive liquids.
We suggest you in any case to use the compatibility tables or our technical department.

2.7 Use of the device
The use of the device must comply with the methods and instructions set out in this manual.
The device can dose chemicals that can be harmful to human health and for this reason it is
essential that they are used by qualified personnel who adopt the appropriate safety methods and
personal protective equipment.
AVOID IMPROPER USE of the equipment in order to avoid damage to things and people, due to
uncontrolled splashes, drips, electrical contacts, etc.
The following uses can be considered improper uses, in indicative and non-exhaustive form:
- Dosing of products not consistent with the materials with which the pump is made;
- Dosing of explosive and / or flammable products;
- Dosing of fluids with excessive viscosity (1000 cps), such as to prevent the priming of the pump
itself;
- Dosage of food liquids, if intended to maintain such use;
- Avoid inverting the pump delivery and suction;
- Avoid powering the pump with voltages other than those indicated in the technical specifications;
- Avoid connecting any equipment other than specific equipment to the signal outputs (level, pulse
counter, current signal, etc.).
2.8 Programming
The HC 100 pump can only operate in constant mode (maximum frequency 105 pulses / minute).
The flow rate is regulated by varying the injection frequency from 0 to 100% using the analog
trimmer (D) on the front panel.
