Special Mounting
Requirements
Vertical pumps must use
the Price Pump Company
vertical mounting plate to
support column. The
mounting plate must be
securely bolted to a rigid
surface.
Direction of Rotation
Note: Motor shaft rotation
is viewed from the suction
end of pump. A rotational
arrow is shown on the front
of the pump volute casing.
Incorrect rotation can
cause pump damage,
failure or reduced
performance, voiding
warranty. It is best to
check rotation by
momentarily energizing or
jogging the motor prior to
filling pump with liquid.

Warning! Do not
operate pump without
liquid for more than a
few seconds, as
damage will result to
bushing.
PLUMBING
All piping should be
supported independently of
the pump. Piping should not
exert any stress on the pump
connections.
Suction piping must be
designed to prevent air from
being trapped in high spots in
the piping. This condition
may cause the pump to vapor
lock as the air bubble moves
into the pump.
1. Discharge Piping.
For flow and discharge head
control it is advisable to
install a valve (globe, ball, or
other adjustable and non-leak
type) in the discharge line
close to the pump. The valve
may be closed during system
repairs to prevent backflow.
By installing a check valve in
the discharge line backflow
can also be prevented during
maintenance or during
periods of pump stoppage.
2. Vertical Pumps
Care must be taken when
attaching piping to the
discharge of vertically
mounted pumps to avoid
piping stress (axial or radial
force) on the discharge port.
Such force will push the
pump out of vertical
alignment, causing premature
failure. No piping stress can
be allowed against the
discharge connection.
Vertically mounted pumps
must have impeller
submerged at start-up. Also,
inlet of pump must be
submerged far enough to
prevent vortexing and the
resulting entrance of air into
the pump. Where conditions
limit how far pump can be
submerged tank baffles
should be used to prevent
vortex formation. The use of
a standpipe (vertical pipe
connected to pump suction)
will allow liquid to be drawn
down below level of the
impeller during operation.
Note, however, that pump
must be submerged during
start-up in order to gain
prime.
OPERATION
Priming. All centrifugal
pumps must be filled with
liquid prior to start up. For
the pump illustrated in this
manual completely fill the
volute and suction lines prior
to operation. It is suggested
that during initial start up the
discharge valve be closed and
then opened as the motor
develops full rpm’s. If pump
does not build up pressure as
motor speed increases, shut
down and reprime pump.
Make sure that liquid flow
into pump is not restricted
(see “Troubleshooting”).
Note: A centrifugal pump’s
flow and head (pressure) will
vary with the amount of
resistance (friction and flow
restrictions) in the discharge
line. As a valve on the
discharge line opens the flow
and motor amp draw will
increase and head will drop.
As a valve on the discharge is
closed the flow and amp draw
will decrease and the head
will increase. If resistance in
the discharge line is not
sufficient the pump will
operate at a condition of
maximum (or “choked”)
flow, also sometimes called
“end of performance curve.”

Maximum horsepower is
required to operate at this
point and motor overload
may result. If excessive amp
draw and motor overload is
recurring, reduce the system
flow by installing a valve on
the discharge line and
restricting flow.
Alternatively, reduce pump
head by trimming impeller to
a smaller diameter. Consult
local Price Pump dealer for
assistance.
CAUTION
Disconnect power to pump
before servicing to avoid
dangerous or fatal electrical
shock hazards.
If pump has been used to
pump hazardous materials
be certain that all materials
have been removed prior to
working on the pump.
Inverting pump with liquid
in it could cause liquid to
get into motor bearings and
cause damage. Before
disassembling be certain all
liquid is removed from the
pump.

TYPE LT Vertical MAINTENANCE AND REPAIR I&O IN162LTV
Before attempting any repairs under warranty, contact Distributor to obtain factory authorization.
Repairs carried out without authorization may void warranty. Many causes of pump system failure are
due to improper system design. Refer to the Trouble Shooting List in this manual before carrying out
pump inspection. CCW = Counter Clockwise CW = Clockwise
DISASSEMBLY
1. Disconnect power source to
motor.
2. Disconnect electrical
connections tagging wires
carefully to preserve correct
rotation. Loosen motor base.
3. Remove pump and motor
assembly to repair area.
Observe position of all parts
prior to disassembly.
4. Remove bolts and remove
volute cover from pump.
5. Remove impeller locknut and
impeller. Unscrew CCW. A
small pair of c-clamp vise grips
may be clamped to the pump
shaft to prevent rotation while
unscrewing impeller locknut.
Avoid damaging the set screws
of the shaft with the vise grips.
7. Remove four motor bolts and
remove column from motor.
8. Loosen setscrews in pump
shaft and remove shaft from
motor. Note: New setscrews
must be used when shaft is
reinstalled.
9. Remove allen cap bolts in
bushing plate assembly and
remove bushing plate
assembly. Note: New bushing
should be used when
rebuilding pump.
REASSEMBLY
1. Clean pump and motor shaft
thoroughly.
2. Assure that the shaft is not
grooved and that there is no
evidence of pitting or fretting
where the bushing rides. If the
shaft is grooved, fretted or
worn, replace it.
3. Install the pump shaft onto the
motor shaft. Ensure all debris
and burrs are removed from the
motor shaft.
4. Install bushing and plate into
column. Tighten three allen
cap screws securely (Note:
Non-galling thread compound
must be used on the allen cap
bolts).
5. Install column onto motor
being careful not to damage
bushing.
6. Install motor bolts and tighten.
7. Install impeller and impeller
locknut. Ensure shoulder of

thread locknut on CW until
snug. Note: Serviceable loctite
must be used on the impeller
locknut.
8. Install new volute gasket and
mount volute cover. Secure
with bolts and tighten evenly.
9. Set impeller clearance. Slide
pump shaft towards volute
cover until impeller touches
volute cover. Back the
impeller and shaft away from
the volute cover approximately
.020" and tighten both pump
shaft setscrews at this time.
Note: Ensure both setscrews
are securely tightened.
10. Invert pump and rotate pump
shaft by hand to ensure
impeller does not rub against
volute cover.
11. Return pump to installation,
reconnect electric connections.
12. Start pump momentarily to
observe shaft rotation. If
rotation corresponds to the
rotation arrow, pump may be
put into service. If rotation is
incorrect, switch any two leads
on 3-phase motors. Check
wiring diagram of motor for
single phase rotation.
13. Start pump allowing adequate
time to purge all air from
system. Observe any gauges,
flow meters, etc., to see of
pump performs properly.
