+
Allow sufficient cooling of the pump before
starting maintenance.
+
Vent the pump and isolate it from the
vacuum system before you start mainte-
nance. Drain catchpots, if applicable.
Ensure that maintenance is done only by suitably
trained and supervised technicians.
The valves and diaphragms as well as the motor capaci-
tors (MD 1C with AC motor) are wear parts. If the rated
ultimate vacuum is no longer achieved or in case of in-
creased 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.
NOTICE
+
Service only one side of the pump at a time to avoid the mixing of
parts.
+
In case, support the pump appropriately.
