3.1 Storage
In the case of prolonged shutdown or storage, we
recommend dismantling the pump and greasing it tho-
roughly. If it cannot be dismantled, it should be filled with
oil via its orifices (inlet and outlet) and rotated slowly by
hand to allow the oil to penetrate. The flange seal surfa-
ces should be thoroughly greased to protect them
against atmospheric oxidation.
3.2 Pumping hot products
CAUTION
THE SURFACES OF THE PUMP CAN
BE AT A TEMPERATURE LIABLE TO
CAUSE INJURY OR SEVERE DAMAGE.
Excessive temperature-
can cause injury or
severe damage.
When pumping products at high temperatures, take care
when starting the pump for the fist time, tighten the bolts
to compensate for expansion effects.
3.3 Pump filled with product at shutdown
WARNING
FAILURE TO INSTALL ADEQUATELY
SIZED PRESSURE RELIEF VALVE(S)
CAN CAUSE PROPERTY DAMAGE, PER-
SONAL INJURY OR DEATH.
Hazardous pressure
can cause
personal injury
or property damage.
In the case where the pumping circuit is situated bet-
ween isolating valves and/or has a check valve, you
must bear in mind the variations in temperature that can
occur, leading in particular to the expansion of the pro-
duct in the circuit. In this case, provide a means of relea-
sing the expansion volume.
The use of a relief valve can suffice for this function. The
opening pressure of this valve must be compatible with
the pressure allowed by the parts composing the circuit.
With products including particles that settle at shutdown,
it is necessary to ensure that the consistency of the
deposited products will not affect the start-up of the
pump.

3. USE
3.4 Starting-up the pump
WARNING
Hazardous pressure
can cause
personal injury
or property damage.
WARNING
Do not operate
without guard
in place.
Before starting up the pump, always ensure that the
pumping conditions are correct, with the corresponding
valves open, especially the inlet valve. For products
requiring heating, they must be brought to their pumping
temperature before starting the pump.
3.5 Shutting down the pump
When shutting down the pump, we recommend waiting
for the pump to stop completely before closing the val-
ves, especially the inlet valve.
3.6 Scrapping
The pump must be scrapped in compliance with the
regulations in force.
During this operation, particular care must be paid to the
drainage stages of the pump (pumped product).
