SAFETY INFORMATION AND INSTRUCTIONS
IMPROPER INSTALLATION, OPERATION OR MAINTENANCE OF PUMP MAY CAUSE SERIOUS INJURY
OR DEATH AND/OR RESULT IN DAMAGE TO PUMP AND/OR OTHER EQUIPMENT. VIKING’S WARRANTY
DOES NOT COVER FAILURE DUE TO IMPROPER INSTALLATION, OPERATION OR MAINTENANCE.
THIS INFORMATION MUST BE FULLY READ BEFORE BEGINNING INSTALLATION, OPERATION OR
MAINTENANCE OF PUMP AND MUST BE KEPT WITH PUMP. PUMP MUST BE INSTALLED, OPERATED
AND MAINTAINED ONLY BY SUITABLY TRAINED AND QUALIFIED PERSONS.
THE FOLLOWING SAFETY INSTRUCTIONS MUST BE FOLLOWED AND ADHERED TO AT ALL TIMES.

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
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 the 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 the above listed
precautionary measures may result in
serious injury or death.
ROTATION:
See Figure 3. Viking 4076/4176 pumps are directional due to
the loading groove in the head. Standard rotation is clockwise
as viewed from the shaft end.
If rotation is to be reversed, the following items need to be
changed:
1. The head and pin assembly must be replaced.
2. Position of the relief valve will have to be changed. Install
so the adjusting screw cap points towards the suction
side of the pump.
3. The flush line must be switched to the opposite port.
LOADING GROOVE
PRESSURE RELIEF VALVES:
Viking pumps are positive displacement pumps and must be
provided with some form of pressure protection. This may
be a relief valve mounted directly on the pump, an in-line
pressure relief valve, a torque limiting device or a rupture
disk.
Pumps equipped with relief valves have them mounted on
the casing.
If pump rotation is reversed during operation, pressure
protection must be provided on both the sides of the pump.
The relief valve adjusting screw cap must always point
towards the pump suction port.
Pressure relief valves are intended for use as a protection for
the pump only and should not be used to control pump flow
or regulate discharge pressure.
MAINTENANCE
Viking 4076/4176 pumps are designed for long, trouble-free
service life under a variety of application conditions with a
minimum of maintenance. The following points will help
provide long service life.
LUBRICATION:
External lubrication must be applied slowly with a hand gun to
the lubrication fitting every 500 hours of operation with multipurpose grease, NLGI #2. Do not over-grease. Applications
involving very high or low temperatures will require other
types of lubrication. Refer to Engineering Service Bulletin
ESB-515. Consult factory with specific lubrication questions.
Note that the bushings used in this pump do not require any
external lubrication.
CLEANING THE PUMP:
Keep the pump as clean as possible. This will facilitate
inspection, adjustment and repair work and help prevent
overlooking a dirt covered grease fitting.
STORAGE:
If the pump is to be stored, or not used for six months or
more, pump must be drained and a light coat of non-detergent
SAE 30 weight oil must be applied to all internal pump parts.
Lubricate the fittings and apply grease to the pump shaft
extension. Viking suggests rotating the pump shaft by hand
one complete revolution every 30 days to circulate the oil.
SUGGESTED REPAIR TOOLS:
The following tools must be available to properly repair
Viking series 4076/4176 pumps. These tools are in addition
to standard mechanics’ tools such as open end wrenches,
pliers and screw drivers. Most items can be obtained from an
industrial supply house.
1. Soft headed hammer
2. Allen wrenches
3. Bearing locknut spanner wrench
4. Spanner wrench, adjustable pin type for use on bearing
housing end cap
5. Brass bar or wood block
6. Arbor press
