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.

●  P

ump  rotation  is  correct  for  the  desired  direction  

  of flow.

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.

WARNING

SAfETY INfORMATION AND INSTRUCTIONS

Danger - 

Failure to follow the indicated 

instruction  may  result  in  serious  injury  

or death.

Warning - 

In addition to possible serious 

injury  or  death,  failure  to  follow  the 

indicated instruction may cause damage 

to pump and/or other equipment.

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.
