3.0 MAINTENANCE
R5 Series, Single Stage, Rotary Vacuum Pumps
require very little maintenance; however, to insure
optimum pump performance, the following steps are
recommended:
3.1 Pump Oil
3.1.1 Oil Level
With the pump installed relatively level, make
sure that there is sufficient clean oil in the pump.
The oil level should be observed on a daily basis
and/or after 8 hours of operation and should be
replenished if it drops below the 1/4 mark on the oil
sight glass. On R5 series pumps you must first shut
the pump off in order to let the oil flow back into the
oil sump prior to checking the sight glass. Allowing
insufficient time for the oil to drain back into the
sump on R5 series pumps prior to adding oil could
result in overfilling.
Oil level readings should be done only when the
pump is turned off. Oil can be added to the oil fill
port (Pos 88) if the pump is shut off and the circu-
lating oil has sufficient time to return to the oil
sump.
Under normal circumstances, it should not be
necessary to add or drain oil from the pump between
recommended oil changes.
A significant drop in oil level means there is an
oil leak or that an exhaust filter is broken, and the
pump should be smoking excessively. It is normal
for the oil to be foamy and light in color in an oper-
ating pump. However, if the oil is milky colored, it
is an indication that water is present in the oil.
Normally, by operating the pump for an extended
period, with the inlet suction blanked off and the gas
ballast (Pos 440) open on RA pumps, the water will
be purged from the oil. If the oil is dark colored, it
is contaminated or carbonized and must be changed.
3.1.2 Oil Type and Quantity
See Section 1.5 - Oil Filling - for details on oil
type and quantity.
3.1.3 Oil and Filter Change
Oil life is dependent upon the conditions to
which it is exposed. A clean, dry air stream and an
oil operating temperature under 210°F are ideal
conditions. When using R530 (hydrocarbon oil) it
is recommended that oil changes are made every
three (3) to four (4) months or 500 to 750 hours of
operation, or as necessary if high heat is contami-
nating the oil. The use of Busch R570 or R590 syn-
thetic oils could extend the operating hours between
oil changes under ideal conditions. Oil samples
should be taken regularly when exceeding the 500-
750 hour recommendation.
Excessive Heat
When the pump is subjected to operating condi-
tions that will cause the oil to be heated above
210°F, the oil will carbonize and become contami-
nated after a relatively low number of operating
hours. The higher the temperature, the quicker the
oil becomes contaminated. If the oil temperature is
too severe, Busch R570 or R590 synthetic oil should
be used to withstand the elevated temperatures. If
synthetic oil is used, the pump should be flushed
with Busch R568 oil as outlined in the Maintenance

Caution: Do not add oil while the pump is
running since hot unfiltered oil vapor may
escape through the oil fill port.
Caution: When changing the oil and filters, it
may be necessary to flush the pump to remove
any build-up of degraded oil from the sumps, oil
lines, radiators, etc. to ensure proper oil flow
through the pump. Reduced oil flow, especially
through radiators and cooling coils, can cause
mechanical damage or extreme overheating
which could cause the oil vapors to ignite.
