MAINTENANCE
PERIODIC MAINTENANCE
Check the oil level daily for the first week of
operation and weekly thereafter. The oil level
should be about midway on the sight gauge when
operating at low inlet pressures. However, the oil
level will change with large changes in pump inlet
pressure. If there are no changes in the oil level,
check for obstructed oil passages.
Check the condition of the oil periodically by
draining a small quantity of oil into a clean
container and visually inspecting it for solid or liquid
contaminants.
Change the oil when it is contaminated. There is
no fixed interval for changing the pump oil, since
applications vary widely. This interval can be
determined only by experience or deterioration of
pump performance. At minimum, change the pump
oil after each 3-month operating (not storage or
idle) period.
CHANGING THE OIL
All moisture, as well as other vapors present in the
system, will be drawn into the pump. Some may be
condensed and will collect in the backing stage oil
reservoir, contaminating the pump oil and causing
poor pump performance. Proper use of gas ballast
will minimize the amount of condensate and reduce
the frequency of oil changes.
Change the oil when it becomes contaminated
with foreign matter or with chemicals. The period
between changes is best determined by the user
for his or her particular operation.
To drain the oil:
1. Remove both drain plugs on the side of the
cylinder.
2. If drain valves are provided, open both drain
valves.
3. To clear all the oil out of the cylinder, open the
pump inlet (suction) to atmosphere. Turn the
pump over a few revolutions to drive the oil out
of the cylinder.
4. Replace the drain plugs.
5. Fill the pump with oil as described in
Filling
the Pump with Oil on page 10
.
NOTE:
N
If the oil is severely contaminated, it
may be necessary to flush the pump by
changing the oil several times, with a
short period of operation between each
change, to check the pump’s blank-off
pressure.
