MOUNTING
If only a bare shaft pump has been supplied,
mount it on a level, rigid base. Connect it to a
motor and operate it at the rotational speed shown
in Specifications on page 4 . Wire the motor
so that the direction of the shaft rotation is as
shown by the arrow cast on the pump. On standard
pumps, this is clockwise when facing the pump
pulley.
V-BELT
When installing a V-belt drive, loosen the motor
mounting screws and slide the motor toward the
pump. Position the V-belt on the pulleys. Move the
motor away from the pump to tighten the drive.
To check the tension of the V-belt drive, apply
normal thumb pressure to the top of the V-belt
midway between the two pulleys. The tightest belt
should not depress more than its own thickness.
Adjust the belt tension as required, but do not over-
tighten or under-tighten the drive. A general rule
for correct V-belt tension is to tighten the drive just
enough to prevent slippage when operating at full
load (that is, with the pump gas ballast valve fully
opened). Recheck the tension of the V-belts after
the first 48 hours of operation.
DISCHARGE PIPING
If desired, connect discharge piping to the
discharge fitting on top of the oil mist eliminator to
vent or reclaim the exhaust gases.
When connecting the discharge piping, use a
dropout trap at the connection to the oil mist
eliminator. Otherwise, condensate from the
discharge piping will drip back into the oil separator
and may contaminate the oil.
A simple dropout trap consists of a tee equipped
with a drain cock for condensate removal. Place
a flexible connection, such as rubber hose, at
the discharge of the pump to eliminate a rigid
connection and to provide a convenient disconnect
point for servicing. Turn down the outside end of
the discharge line to prevent rain entry.
VACUUM PIPING
The vacuum piping to the pump inlet should be as
large and as short as possible. Use manifolding
that is no smaller than the pump inlet. Tuthill
recommends arranging the inlet manifolding to
prevent oil migration back into the system. See
Figure 3-1 for recommended arrangements of
vacuum manifolding with integral oil baffles.
