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 drain/fill plug (100) in
the motor housing. Tip the pump and drain off a
small amount of oil into a transparent cup. If the oil
level is abnormally low, or the color milky or dark,
refer to Draining Oil From Seal Cavity in this sec­
tion for instructions and troubleshooting tips.
To fill the seal cavity, remove the seal cavity drain/fill
plug (100) and add 7 ounces (0,2 liter) of SAE No.
10 non‐detergent oil. Refer to Section B, Installa­
tion, for positioning of the pump during filling of the
seal cavity. Apply `Loctite Pipe Sealant With Teflon
No. 592.' or equivalent to the threads of the pipe
plug, before reinstalling the plug.
Motor Cavity
The motor cavity is cooled by the liquid being
pumped. No further lubrication is required.
