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.

12.2 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 extremities of the suction line and the high pressure outlet hose inside the container.
f) Start up the diaphragm 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.
