LUBRICATION
Seal Cavity
Check the oil level in the seal cavity before initial
startup, after the first two weeks of operation, and
every month thereafter.
Check the oil level only when the pump
is cool. If the oil level plug is removed
when the pump is hot, pressure in the
seal cavity can cause hot oil to be
ejected as the plug is removed.
To check the seal cavity oil, lay the pump on its side
and remove the seal cavity plug (8) in the interme­
diate. Tip the pump and drain off a small amount of
oil into a transparent cup. If the oil level is abnor­
mally low, or the color milky or dark, refer to Drain­
ing Oil From Seal Cavity in this section for instruc­
tions and troubleshooting tips. If the oil is clear, ap­
ply `Loctite Pipe Sealant With Teflon No. 592.' or
equivalent to the threads of the pipe plug, before
reinstalling the plug.
To fill the seal cavity, remove the pipe plug (10) and
add the recommended grade of submersible
pump oil. Apply `Loctite Pipe Sealant With Teflon
No. 592.' or equivalent to the threads of the pipe
plug, before reinstalling the plug.
See Table E‐2 for quantity of lubricant when lubri­
cating a dry (overhauled) pump. See Table E‐3 for
lubricant specifications.
The grade of lubricant used is critical to the opera­
tion of this pump. Use premium quality hydraulic oil
as specified in the following table. Oil must be
stored in a clean, tightly closed container in a rea­
sonably dry environment.

Motor Housing Cavity
With the pump in an upright position, remove the
pipe cap (30) on the top of the pump. See Table E‐2
and add the recommended grade of lubricant
(Table E‐3) to the motor cavity. Maintain the oil at
this level. Apply `Loctite Pipe Sealant With Teflon
No. 592' or equivalent sealant to the threads of the
