WARNING
Danger - Failure to follow the indicated
instruction may result in serious injury
!
or death.
BEFORE opening any liquid chamber (pumping
chamber, reservoir, relief valve adjusting cap fitting,
etc.) be sure that :
● Any pressure in the chamber has been completely
vented through the suction or discharge lines or
other appropriate openings or connections.
● The pump drive system means (motor, turbine,
engine, etc.) has been “locked out” or otherwise
been made non-operational so that it cannot be
started while work is being done on the pump.
● You know what material the pump has been
handling, have obtained a material safety data
sheet (MSDS) for the material, and understand
and follow all precautions appropriate for the safe
handling of the material.
BEFORE operating the pump, be sure all drive guards
are in place.
DO NOT operate pump if the suction or discharge
piping is not connected.
DO NOT place fingers into the pumping chamber or
its connection ports or into any part of the drive train
if there is any possibility of the pump shafts being
rotated.
DO NOT exceed the pumps rated pressure, speed, and
temperature, or change the system/duty parameters
from those the pump was originally supplied, without
confirming its suitability for the new service.
BEFORE operating the pump, be sure that:
● It is clean and free from debris
● all valves in the suction and discharge pipelines
are fully opened.
● All piping connected to the pump is fully supported
and correctly aligned with the pump.
● Pump rotation is correct for the desired direction
of flow.

WARNING
Warning - In addition to possible serious
injury or death, failure to follow the
indicated instruction may cause damage
to pump and/or other equipment.
INSTALL pressure gauges/sensors next to the
pump suction and discharge connections to monitor
pressures.
USE extreme caution when lifting the pump. Suitable
lifting devices should be used when appropriate. Lifting
eyes installed on the pump must be used only to lift
the pump, not the pump with drive and/or base plate.
If the pump is mounted on a base plate, the base plate
must be used for all lifting purposes. If slings are used
for lifting, they must be safely and securely attached.
For weight of the pump alone (which does not include
the drive and/or base plate) refer to the Viking Pump
product catalog.
DO NOT attempt to dismantle a pressure relief valve
that has not had the spring pressure relieved or is
mounted on a pump that is operating.
AVOID contact with hot areas of the pump and/or
drive. Certain operating conditions, temperature
control devices (jackets, heat-tracing, etc.), improper
installation, improper operation, and improper
maintenance can all cause high temperatures on the
pump and/or drive.
THE PUMP must be provided with pressure protection.
This may be provided through a relief valve mounted
directly on the pump, an in-line pressure relief valve,
a torque limiting device, or a rupture disk. If pump
rotation may be reversed during operation, pressure
protection must be provided on both sides of pump.
Relief valve adjusting screw caps must always point
towards suction side of the pump. If pump rotation is
reversed, position of the relief valve must be changed.
Pressure relief valves cannot be used to control pump
flow or regulate discharge pressure. For additional
information, refer to Viking Pump’s Technical Service
Manual TSM 000 and Engineering Service Bulletin
ESB-31.
THE PUMP must be installed in a matter that allows
safe access for routine maintenance and for inspection
during operation to check for leakage and monitor
pump operation.

SPECIAL INFORMATION
5. Pressure relief valves cannot be used to control pump
flow or regulate discharge pressure.
For additional information on pressure relief valves, Refer
to Technical Service Manual TSM000 and Engineering
Service Bulletin ESB-31.
SPECIAL MECHANICAL SEALS:
Extra care should be taken in repair of these pumps. Be sure
to read and follow all special instructions supplied with your
pump.
DANGER !
Before opening any Viking pump liquid
chamber (pumping chamber, reservoir,
relief valve adjusting cap fitting, etc.)
Be sure:
1. That any pressure in the chamber has
been completely vented through the
suction or discharge lines or other
appropriate openings or connections.
2. That the driving means (motor,
turbine, engine, etc.) has been “locked
out” or made non-operational so that
it cannot be started while work is
being done on pump.
3. That you know what liquid the
pump has been handling and the
precautions necessary to safely
handle the liquid. Obtain a material
safety data sheet (MSDS) for the
liquid to be sure these precautions
are understood.
Failure to follow above listed
precautionary measures may result in
serious injury or death.
ROTATION: Viking pumps operate equally well in a
clockwise or counterclockwise rotation. Shaft rotation
determines which port is suction and which is discharge.
Port in area where pumping elements (gear teeth) come out
of mesh is suction port.
PRESSURE RELIEF VALVES:
1. Viking pumps are positive displacement pumps and
must be provided with some sort of pressure protection.
This may be a relief valve mounted directly on the pump,
an inline pressure relief valve, a torque limiting device or
a rupture disk.
2. There are relief valve options available on those pump
models designed to accept a relief valve. Options may
include a return to tank relief valve and a jacketed relief
valve. Pumps equipped with a jacketed head plate are
generally not available with a relief valve.
3. If pump rotation is reversed during operation, pressure
protection must be provided on both sides of pump.
4. Relief valve adjusting screw cap must always point
towards suction side of pump. If pump rotation is
reversed, remove pressure relief valve and turn end for
end.
MAINTENANCE
Series 124A, 4124A, 126A, 4126A, 123A, 4123A, 127A, and
4127A pumps are designed for long, trouble-free service life
under a wide variety of application conditions with a minimum
of maintenance. The points listed below will help provide
long service life.
LUBRICATION: External lubrication must be applied slowly
with a hand gun to all lubrication fittings every 500 hours
of operation with multi-purpose grease, NLGI # 2. Refer to
Engineering Service Bulletin ESB-515. Consult factory with
specific lubrication questions. Applications involving very high
or low temperatures will require other types of lubrication.
PACKING ADJUSTMENT: New packed pumps require initial
packing adjustment to control leakage as packing “runs in”.
Make initial adjustments carefully and do not over -tighten
packing gland. After initial adjustment, inspection will reveal
need for packing gland adjustment or packing replacement.
Refer to instructions under Disassembly and Assembly,
page 7, regarding repacking pump.
CLEANING PUMP: Keep pump as clean as possible. This
will facilitate inspection, adjustment and repair work and help
prevent overlooking a dirt covered grease fitting.
STORAGE: If pump is to be stored, or not used for six months
or more, pump must be drained and a light coat of
light oil must be applied to all internal pump parts.
Lubricate fittings and apply grease to pump shaft extension.
Viking suggests rotating pump shaft by hand one complete
revolution every 30 days to circulate the oil. Tighten all pump
assembly bolts before putting pump in service after being
stored.
SUGGESTED REPAIR TOOLS: The following tools must
be available to properly repair series 124A, 4124A, 126A,
4126A, 123A, 4123A, 127A, and 4127A pumps. These tools
