The Watchdog
®
oiler system was designed for use on closed system environments. The
Inpro VBXX-D labyrinth seals used on these pumps can create a situation where unequal
pressure causes the oiler to overfill. This might occur during intermittent operation. In
order to eliminate the pressure differential that creates this problem, Watchdog supplies a
breather with a filter.
If plant environments or requirements are not suitable for vented bearing frames, then do
not use the Watchdog oiler.
Install the Watchdog oiler in the connection for the sight glass. The oiler does not require
any setting dimensions.

Greased-for-life bearing lubrication
The bearing manufacturer fills greased-for-life bearings with grease and seals them at the factory. You do
not need to lubricate or seal these bearings. Refer to the Maintenance chapter for re-greasing and
maintenance procedures for these bearings.
Shaft-sealing options
In most cases, the manufacturer seals the shaft before shipping the pump. If your pump does not have a
sealed shaft, see the Shaft-seal maintenance section in the Maintenance chapter.
This model uses these types of shaft seals:
• Cartridge mechanical seal
• Conventional inside-component mechanical seal
• Dynamic seal
• Packed-stuffing-box option
Mechanical seal options
Pumps are usually shipped with mechanical seals installed. If they are not, then refer to the mechanical seal
manufacturer's installation instructions.
These are the mechanical seal options for this pump:
• Cartridge mechanical seal
• Conventional inside component mechanical seal
