Checking / Maintenance
Before starting any disassembly work, dis-
connect all electrical connections to the
pump. Reliably prevent the pump from run-
ning up.
When the pump has been pumping hazar-
dous substances, determine the nature of
the hazard and make sure that the appro-
priate safety measures are observed.
Observe all safety regulations!
When disposing of the waste oil, observe
the applicable regulations for the safety of
the environment.
Due to the concept of the TRIVAC E these pumps will
hardly require any maintenance under normal operating
conditions. The necessary maintenance work is descri-
bed in the following sections. In addition a maintenance
plan is provided in Section 4.
All work should be left to trained personnel.
Improperly performed maintenance or
repair work endangers the durability and
operational readiness and will lead to diffi-
culties when wanting to file any warranty
claims.
Also available from LEYBOLD are seminars covering
practical aspects like maintenance, repair and checking
of the TRIVAC E which are run under the supervision of
our experts. For more information on these seminars
please contact us at LEYBOLD.
If the pump is used in strongly contamina-
ted ambient air you must ensure that opera-
tion of the gas ballast system and the air
cooling is not impaired.
When the TRIVAC E has been pumping
corrosive media, we strongly recommend
that you conduct any possibly due mainten-
ance immediately in order to avoid corrosi-
on during standstill.
Spare Parts are contained in the Repair Sets and in the
Maintenance Kits. If required, ask us for a quotation on
spare parts.
In the case of custom models and variants please always
state the custom, variant and serial number.
3.1 Checking the Oil Level
During operation the oil level of the TRIVAC E must
always be visible between the marks on oil viewing glass
(7/2 and 7/3). The quantity of oil must be checked and
topped up as required.
Recommendation: The oil level should always be
visible in the middle of the oil
viewing glass.
The pump must be switched off before top-
ping up any oil.
3.1.1 Oil Check
The ageing process of the standard operating agent
N 62 / HE 200 (see Section 1.2.1) basically depends on
the operating conditions of the pump.You may check the
condition of the oil as follows:
• Visually
Normally the oil will be light and transparent. In the case
of increasing discolouration of the oil (it becomes darker)
we recommend that you exchange the oil.
• Chemically
The neutralisation value for N 62 is determined in accor-
dance with DIN 51558. When the neutralisation value
exceeds the value of 2 you must change the oil.
• Mechanically
When the viscosity of N 62 exceeds a value of 240 mPas
at 25 °C (20 % over viscosity of fresh oil) we recommend
that you change the oil.
When gases or liquids are dissolved in the oil, the attain-
able ultimate pressure will be impaired.In such cases the
oil may possibly be degassed by letting the pump run for
about 30 minutes with the intake line closed and the gas
ballast valve open.
