rotary back on the sleeve until it is about 1 inch
beyond the stuffing box face. Push the gland back
onto the studs, pushing the rotary back along the
sleeve. Tighten the gland nuts. This ensures
contact, no other adjustments are needed. The lip
seal is pressed into the gland and no adjustment
is required. Both seals are designed to run dry, so
no flush is required.
NOTE: HT 3196, NM 3196, 3796, and 3198 are
not available with dynamic seal options.
Pumps that are not self-priming must be
fully primed at all times during operation.
The only model line in this manual that is
self-priming is the 3796.
PRIMING PUMP
(3196, CV 3196, HT3196, LF 3196, 3198, and NM 3196)
Never start the pump until it has been properly
primed. Several different methods of priming can be
used, depending upon type of installation and service
involved.
Suction Supply Above Pump
1. Slowly open the suction valve (Fig. 30).
2. Open air vents on the suction and discharge
piping until water flows out.
3. Close the vent valves.
Suction Supply Below Pump (except 3796)
A foot valve and outside source of liquid may be used
to prime the pump. Outside source of liquid can come
from a priming pump, pressurized discharge line, or
other outside supply (Fig. 31 and 32).
NOTE: Model 3796 is a self-priming pump and
does not require the use of a foot valve in the
suction line. Refer to the pump’s performance
curve to determine the time required for
priming.
1. Close discharge valve and open air vents in
casing.
2. Open valve in outside supply line until only liquid
escapes from vent valves.
3. Close the vent valves and then the outside supply
line.
