Start-up

1. At first start-up, verify that the rotation direction is correct.
2. Check the pump is fed correctly.
3. Start-up the pump without any load.
4. Check that the rotation rpm during operation does not
exceed the nominal rpm of the pump.
5. Let the pump run for a time of no less than 3 minutes,
before putting it under pressure.
6. Before each pump stop, reset pressure by means of the
control valve or with any relieving devices.
Should there be any priming trouble due to
insufficient supply, it is possible to remove the
three plugs in front of the head (except for the
LK36 version) as shown in pos.  Fig. 11.

PUMP STORAGE

12.1 Method for filling pump with anti-corrosion
emulsion or anti-freeze solution
Method for filling pump with anti-corrosion emulsion or anti-
freeze solution using an external diaphragm pump based on
the layout shown in par. 9.6:
a) Close the filter drainage, if open.
b) Make sure the connecting pipe is clean, spread with grease
and connect them to the high pressure discharge.
c) Fix the suction pipe to the diaphragm pump, open the
pump suction connection and attach the pipe between it
and the diaphragm pump.
d) Fill the container with solution/emulsion.
e) Insert the free ends of the suction pipe and the high
pressure exhaust pipe inside the container.
f ) Switch on the diaphragm pump.
g) Pump the emulsion until it exits from the high pressure
exhaust pipe.
h) Continue pumping for at least another minute. The
