clean oil back into the pump. If you work adequately, you will never have to change the
oil in an oxygen pump.
Maintenance of the pump
When carrying out maintenance work and when users could be injured by
mobile parts and electrical components, the pump must be totally isolated and
disconnected. It is extremely important not to start the unit again during maintenance
work. Do not carry out maintenance work in a pump with working temperature, as there
is risk of hot parts or lubricant.
Read carefully the set up and maintenance manual of the vacuum pump before
handling it.
The oil in the pump must be firstly changed after 100 hour work and then every
500 hour work or every 3 months. The oil filter must be changed at the same time. We
recommend to regularly verify the oil level in the pump and to add some oil if
necessary. Fill ¾ of the oil deposit, never more.
** The oil already used must be eliminated according to the existing
health, security and environment standards. If you decide to use a new
type of oil, you must completely empty the oil separator and cooling unit
(if there is one).**
An anti-emulsion oil must be used when working with high-moisture products.
This type of oil does not mix with water, but we recommend to take out water in order
to work correctly.
On the other hand, it must be said that oxygen pumps need a very expensive
special oil which does not need to be changed at all. Water must also be taken out of
these pumps, but a different procedure must be followed.
