The following maintenance can be carried out on the dry pumping system between the
overhauls. Contact us for the details and training:
▪ Check the oil level. Refer to Checking the oil levels and relling on page 71.
▪ Inspect the connecons, pipelines, cables and ngs. Refer to Inspect the
connecons, pipelines, cables and ngs on page 72.
▪ Inspect and clean the exhaust pipe, elbow and check valve.
5.4.1 Checking the oil levels and relling
WARNING:
The use of suitable protecve gloves and eye protecon is recommended when
carrying out this procedure. Personal protecve equipments should be checked and
used as specied by its supplier.
CAUTION:
Ensure that the oil levels in the dry pump and the mechanical booster pump (where
applicable) are correct. If a pump oil level is incorrect, pump performance may be
aected and the pump may be damaged.
The dry pump and booster (if ed) each have two sight glasses. One is located on the
end cover (refer to Figure: Locaon of the oil sight glass and the ll plug on end cover)
and the other is located on the gearbox (refer to Figure: Locaon of the oil sight glass
and the ll plug on gearbox). Note that the GXS750 dry pumping system has a gearbox
with a sight glass at each end and so Figure: Locaon of the oil sight glass and the ll
plug on gearbox applies to both ends. One is accessible from the le side of the dry
pumping system and the other is accessible from the right side.
The GXS 450, 450/2600, 450/4200, 750, 750/2600 and 750/4200 dry pumping systems
are provided with slots in the side panels to enable the oil levels to be checked without
removal of the side panels. To check oil levels on these systems:
1. Switch o the dry pumping system and allow it to stand for at least 5 minutes.
2. Check that the oil level is in line with the MAX indicator. If the oil level is below the
maximum it must be topped up.
All other GXS pumps require the dry pumping system side panels to be removed in order
to check the oil level. To check oil levels on these systems:
1.
Switch o the dry pumping system and allow it to stand for at least 5 minutes.
2.
Remove the side panels.
3.
Check that the oil level is in line with the MAX indicator. If the oil level is below the
maximum it must be topped up.
To top up the oil levels, all GXS pumping systems require side panels to be removed:
1.
Refer to Figure: Locaon of the oil sight glass and the ll plug on end cover and
Figure: Locaon of the oil sight glass and the ll plug on gearbox to locate the oil
ll plugs on the top of the end cover and gearbox.
2.
Remove the appropriate oil ll plug and carefully top up with oil. Refer to General
technical data on page 15 for specicaon.
