Changing the LABOVAC oil type
WARNING !
To ensure a smooth working process of the combination pump system may be used
excluding original oils of the type LABOVAC.
If you use oils different from the LABOVAC oils mentioned in this context the
warranty claim terminates!
The chemvac combination pump system is checked with our original oil type
LABOVAC 14 and we enclose a separate bottle of this oil to fill the pump.
If you want to use another type of
LABOVAC
Oil, please note the following:
Our
Mineral oils
LABOVAC 10
and
LABOVAC 12S
may be exchanged among each
other:
- Drain the oil,
see chapter 6.2.1.2
- Flush the vacuum pump with new oil
- Fill the vacuum pump with new oil
The exchange of synthetic oils like
LABOVAC 11
and
LABOVAC 14
with mineral oils like
LABOVAC 10
or
LABOVAC 12S
will be executed in the same way.
The synthetic oil
LABOVAC 13
is an exception which
CANNOT
be mixed or
exchanged with other
LABOVAC
oil types.
Even complete disassembly and cleaning of the vacuum pump always involves the risk of
small quantities of oil remaining. We therefore recommend asking the manufacturer di-
rectly about vacuum pumps with a special oil filling, for example
LABOVAC 13
.
