6.1 Lubrication
The hose is lubricated with a special mixture. MOUVEX
lubricant is recommended to lengthen the service life of
the hose.
It is recommended to change the lubricant when :
• Replacing the hose.
• Replacing the hose due to maintenance operation.
• After 2000 hours of operation.
Amount of lubricant required :
A40 and AS40 pumps require
2,5 liters of lubricant.
The minimum working or storage temperature for the
pump lubricant is 0°C (32°F).
For use / storage at lower ambient temperatures, it is
necessary to add ethylene glycol to the MOUVEX lubri-
cant. To maintain optimum lubrication, the volume of
ethylene glycol should remain between 4% and 6% of
the total volume of lubricant, and the total quantity of
lubricant present in the pump must be in compliance
with the value specified above.
In any case, the ambient temperature should never be
lower than -20°C (-4°F).
6.2 Hose
Some pumped liquids require the hose to be cleaned
after each operation to prevent solidification of the fluid
inside the hose.
The hose can be easily washed with a cleaning agent
that is compatible with the hose material and the pumped
product.
It is recommended that the hose be monitored so that it
can be replaced before any breakdown should occur.
Preventive replacement is advisable.
Temperature threshold values for the liquid pumped
depend directly on the materials that make up the hose.
Refer to technical characteristics on the cover page for
the corresponding values.
It is important to note that the temperature of the pumped
liquid influences the limits of use of the pump and that a
rise of the temperature of the pumped liquid has to come
along with a modification of the service pressure / of the
speed of rotation so as to respect the limits defined in §
TECHNICAL SPECIFICATIONS and eventually of a
modification of the shimming of the shoe as specified in
the § SHIMMING THE SHOES.
When required, you can contact our Technical Services
at any time to ask for the information you require.
