2.5 Hydraulic connection
After the exact installation of the pump (see generalities), proceed with the connection.
Suction:
connect the suction tube (PVC soft cristal) to the foot filter that is supplied and put it in the
hose clamp, lock the tube closing the nut. If it utilises a level probe, this one has to be connected to
the filter through the support that is supplied. Put the foot filter into the liquid suction lift tank.
Connect the other extremity to the suction of the pump (lower part of the pump head), unscrew the
nut from the nipple, take off the rubber white disk situated on the tube connection. Let pass the tube
through the nut and the adaptor for the 4x6 tube with a simultaneous action of pressing and
rotating, put the tube on the nipple conical connection (hose clamp) till the end; lock up everything
by closing the nuts well. See fig. 7

Connect the other extremity to the delivery of the pump (upper part of the pump head), by repeating
the instructions above. See fig. 7
Purge:

urge (2 mt PVC crystal) in the hose clamp
situated on the pump head lower to the right, while the other extremity is to be put into the suction
lift tank. See fig. 8
INSTRUCTION FOR PRIMING
For the priming of the pump in case of high against pressure in the injection, turn the purge knob for
a quarter or a half of round (see fig. 8) until the head pump is completely full. Screw down again the
knob.
ATTENTION!!
If it is necessary to take the pump off the plant, it is important to put the white
disk in again, so as to avoid any exit of the liquid contained in the pump head
from dripping out. - During the installation ensure that the discharge tubing is
fixed correctly to avoid that it does not rub against hard bodies. Avoid also
use less bends both on discharge and suction tubing.

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.
