3.1 Pump storage
If the pump is inactive for more than 3 months, remove
the hose or the shoes. If you do not wish to remove the
hose or the shoes, operate the pump for 5 minutes once
a week.
Check that the wheel is always in such a position that
one of the shoes can be seen through the window.
For storage at temperatures below 0 °C (32 °F), specific
precautions must be taken. Refer to § LUBRICATION.
3.2 Hose storage
Hose shelf life is limited to two years from the date of
purchase.
The hoses must be stored in a cool place protected from
light. Exposure to ultraviolet rays accelerates deteriora-
tion of the material, thus reducing shelf life.
3.3 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.
3.4 Pump filled with product at shutdown
In the case where the pumping circuit is situated between
isolating valves and/or has a check valve, you must bear
in mind the variations in temperature that can occur, lea-
ding in particular to the expansion of the product in the cir-
cuit. In this case, provide a means of releasing the expan-
sion 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 deposi-
ted products will not affect the start-up of the pump.

can cause
personal injury
or property damage.
When the hose breaks, there is a risk that the lubricant
