2.0 - EXACTUS SERIES METERING PUMPS
2.1 - OPERATION
The metering pump is activated by a teflon® diaphragm mounted on a piston of an electromagnet.
When the piston of the electromagnet is attracted, a pressure is produced in the pump body with an expulsion
of liquid from the discharge valve. Once the electric impulse is finished a spring brings the piston back to the
initial position, with a recall of liquid through the suction valve.
The operation is simple the pump does not need lubrication, therefore maintenance is reduced almost to zero.
The materials used for the construction of the pump make it particularly suitable for aggressive liquids.
The metering pump has been designed to feed liquids with capacities from 0 to 20 l/h and pressures from 0 to
10 bar (depending on the model selected).
