OPERATION PAGE C − 5
LUBRICATION
Do not remove plates, covers, gauges,
pipe plugs or fittings from an over-
heated pump. Vapor pressure within the
pump can cause parts being disen-
gaged to be ejected with great force. Al-
low the pump to completely cool before
servicing.
On a new pump, check the oil level in the seal cav-
ity before initial startup, after the first two weeks of
operation, and every month thereafter.
Before installing or removing the lubrication
plug(s), always clean the area around the plug(s)
to prevent contamination.
Draining Oil
Refer to the Parts List Manual for drain plug loca-
tion.
For the smaller pumps, lay the pump horizontal on
a flat work surface with the seal cavity drain plug
facing up. Remove the drain plug slowly to release
any pressure. Install a short pipe nipple in the hole.
Place a clean container under the plug and roll the
pump on its side to drain the seal housing.
For the larger pumps, remove the drain plug slowly
to release any pressure. Install a short pipe nipple
in the hole. Place a clean container under the plug
and using a hoist, tilt the pump at an angle of ap-
proximately 60 degrees.
Condition Of Oil
Check the condition of the oil drained from the
pump. Clear oil indicates that the pump seal(s) are
functioning properly. If the oil is milky or contains
a small amount of water, it must be changed.
If the oil contains a large amount of water, it must
be changed, and the seal(s) must be checked be-
fore the pump is put back in operation (refer to the
Maintenance and Repair Manual).
Adding Oil
Due to differences in pump design, the quantity of
oil and manner in which oil is to be added to the
seal cavity varies between pump models. Refer to
Table B−2 in INSTALLATION for oil capacities and
positions for filling the seal cavity in each pump.
The grade of lubricant used is critical to the opera-
tion of this pump. Use premium quality submers-
ible pump oil as specified in the following table. Oil
must be stored in a clean, tightly closed container
in a reasonably dry environment.
When lubricating the seal cavity, remove the lubri-
cation plug as indicated in Draining Oil, and posi-
tion the pump as indicated in Table B−2. Add pre-
mium quality submersible pump oil through this
plug hole. If the pump is to be positioned vertically
or at an angle, fill the cavity to the bottom of the
plug hole. If the pump is to be positioned horizon-
tally, completely fill the cavity.
Install and tighten the lubrication plug.
