VACUUBRAND MV 10 - Manual (Page 37)

page 37 of 51
Ensure that maintenance is done only by suitably
trained and supervised technicians.
The valves and diaphragms as well as the motor capac-
itors are wear parts. If the rated ultimate vacuum is no
longer achieved or in case of increased noise level, the
pump interior, the diaphragms and the valves must be
cleaned and the diaphragms and valves must be checked
for cracks or other damage.
All bearings are encapsulated and are filled with long-life
lubricant. Under normal operating conditions, the drive
system is maintenance free.
In demanding circumstances, it may be efficient to
check and clean the pump heads on a regular basis. In
normal use, the lifetime of the diaphragms and valves
is typically 15,000 operating hours.
- Prevent internal condensation, transfer of liquids or
dust. The diaphragms and valves will be damaged if
liquid is pumped in significant amount.
- Carry out maintenance frequently if the pump is ex-
posed to corrosive media or in case of deposits.
- Regular maintenance will improve the lifetime of the
pump and also protect both users and the environment.
