ORIENTATION AND REVERSING OF BYPASS
Bypass orientation
The bypass will protect the pump only for one direction of
rotation, but can be reversed. It is therefore important to
ensure that it is correctly orientated by checking that the cap
is on the suction side, reversing it if necessary.
Short duration (≤ 1 month)
WARNING
IF PUMPING HAZARDOUS OR TOXIC
FLUIDS, THE SYSTEM MUST BE FLUSHED
PRIOR TO PERFORMING ANY SERVICE
OPERATION.
Toxic or hazardous
fluids can cause
serious injury.
MOUVEX pumps and motor-driven pumps are well lubricated
when delivered to protect the internal parts during brief storage
in a building where :
• the temperature remains between 10°C and 50°C.
• the relative humidity does not exceed 60%.
• exposure to vibration is limited.
• pump is stored in an area sheltered from bad weather
and sun.
Long duration (> 1 month)
The recommendations from the manufacturer should be follo-
wed if the pump is stored with its gear motor.
Pump ports should be filled with a non-corrosive liquid that it
compatible with the pump components in order to prevent
corrosion.
Unpainted external surfaces of the pump (e.g. shafts, couplings,
etc.) should be covered in some form of anti-corrosion protec-
tion.

Reversing bypass
Unscrew cap 833 and loosen adjusting nut 834 so as to relax
spring 824 as much as possible.
Remove part 828 and the parts fast with it. Remove valve
823, spring 824 and guide 825 and assemble them all on the
other side.
Fit plug 812 and gasket 848 in the position previously occu-
ped by part 828.
Then adjust the bypass by tightening up adjusting nut 834 so
as tighten spring 824.
Screw cap 833 back into position.
STORAGE
The bearing should be well greased. If the pump is to be stored
for more than the life of the grease, this one should be replaced
in time to prevent an excessive degradation of its qualities.
The best storage conditions are inside a building that meets
the conditions set out above.
If inside storage is not possible, the materials should be cove-
red to prevent direct exposure to sun and bad weather. This
protection should also prevent condensation.
The pump should be turned a few revolutions manually every
two months.
Restarting
Follow the standard start-up procedure for the pump/ motor-
driven pump, as well as the instructions below.
Turn the pump by hand to make sure the parts move freely.
Replace the grease used to lubricate the bearing.
If the pump has a safety bypass, remove it and inspect the
parts and make sure they move freely.
