10.2 Start-up
1. When starting the pump for the first time, check for
the correct direction of rotation.
2. The pump must be started off-load.
3. Verify correct feeding pressure.
4. During operation, check that the rotating speed does
not exceed the rated value.
5. Before putting the pump under pressure let it run for
at least 3 minutes.
6. Before stopping the pump, release the pressure by
acting on the adjustment valve or on any discharging
device.
In case of priming problems caused by insuffi-
cient feeding, it’s possible to intervene by
removing the three front caps on the head (see
position 3, fig. 11).

12. STOPPING THE PUMP FOR LONG PERIODS
12.1 Filling the Pump With An Anti-Corrosion
Emulsion or Anit-freeze By Using An External
Diaphragm Pump As In The Layout Shown in
Paragraph 9.7.
a) Close the filter draining, if open.
b) Be sure that the connecting hose is clean, spread
with grease and connect it to the high pressure outlet
port.
c) Fit a suction hose to the membrane pump. Open the
pump suction connection and fit hose between it and
the membrane pump.
d) Fill the container with the solution/emulsion.
e) Put the free extremeties of the suction line and the
high pressure outlet hose inside the container.
f) Start up the diphragm pump.
g) Pump the emulsion until it comes out of the high
pressure hose.
h) Continue pumping for at least another minute; if
needed, the emulsion can be reinforced by adding,
for example, Shell Donax
i) Stop the pump, remove the hose from the suction
connection and close it with a plug.
j) Remove the hose from the high pressure outlet port.
Clean, grease and plug both connections and the
hoses.
12.2 Hoses
a) Before greasing and protecting the hoses according
to the previously described procedure, dry the con
nections using compressed air.
b) Cover with polyethelene.
c) Do not wrap them too tightly; be sure there is no
bending.
