6.2 Maintenance plan
The plan shown in Table: Maintenance plan on page 34 details the roune maintenance
operaons necessary to maintain the pump in normal use. Instrucons for each
operaon are given in the secon shown.
More frequent maintenance may be required if the pump is used to process corrosive or
abrasive gases and vapours, in these circumstances, we recommend you to replace the
pump seals every year. If necessary, adjust the maintenance plan according to
experience.
When carrying out maintenance on the pump, use our spares and maintenance kits,
these contain all the components necessary to complete maintenance operaons
successfully. The item numbers of the spares and kits are given in Spares.
Examine the condion of any external accessory, lters or traps (if ed) when carrying
out maintenance on the pump. Refer to the instrucons supplied with these accessories
for the necessary maintenance procedures.

6.3 Check the oil level
Note:
1. If required, it is possible to check the oil
‑ level while the pump is operang, however
the pump must be switched o. Isolate the pump and other components in the pumping
system from the electrical supply before pouring oil into the pump.
2. Do not mix hydrocarbon lubricants with PFPE or vice versa. If the oil is mixed, drain
and rell with clean oil as described in Replace the oil on page 35.
