Operating  a  pump  against  a  blocked  or 
restricted  discharge  line  can  produce 
excessive  pressures  in  the  entire  discharge 
system,  which  can  damage  or  burst 
discharge system components.   

 

 

DANGER 

 

Never  operate  a  pump  without  a 
properly sized pressure relief valve or 
working  overpressure  shutdown    in 
the 

discharge 

line 

immediately 

adjacent to the pump discharge. 
 

The  relief  valve  should  be  placed  in  the 
flowing  discharge  line  and  not  at  the 
opposite  end  of  the discharge manifold in a 
dead  end  connection.    The  dead  end  may 
become  clogged  with  solid  material  carried 
in  the  fluid,  which  could  prevent  proper 
relief valve operation. 
 
 

  

 

 

DANGER 

 

Never place a shut-off valve or any 
other component between the pump 
discharge connection and the 
pressure relief valve.
 

 
 
Make  sure  the  pressure  relief  valve  is 
installed so any pressurized relief discharge 
from  the  valve  is  directed  away  from 
possible  contact  with  people  or  equipment.  
The  relief  valve  must  be  set  to  relieve  at  a 
pressure  equal  to  or  below  the  maximum 
pressure  values  shown  on  the  pump  data 
plate.    However,  if  a  component  is  used  in 
the  discharge  system  with  a  lower  rated 
pressure  capability  than  that  listed  on  the 
pump  data  plate,  the  pressure  relief  valve 
must be set to relieve at a pressure equal to 
or  below  the  rated  capability  of  the  lowest 
rated component. 
 
Before  starting  the  pump  every  time, 
check to insure: 
 

 

The pressure relief valve is in good 
operating  condition and has been set to 
the proper relief pressure. 

 

 

Any  pipe  line used to direct pressurized 
relief flow to another location, such as a 
collecting tank, is not blocked. 

 

 

The  discharge  system  is  not  blocked 
and  all  the  discharge  line  valves  are 
open. 

 
Check  all  fluid  end  discharge  system 
components  including  pipes,  elbows 
connections,  threads,  fasteners,  hoses, 
etc.,  at  least  once  every  six  months  to 
confirm  their  structural  adequacy.
    With 
time,  wear,  corrosion  and  fatigue  can 
reduce  the  strength  of  all  components.  
Magnetic  iron  and  steel  components should 
be  checked  with  magnetic  particle  or  dye 
penetrant 

crack 

detection 

equipment.  

Nonmagnetic  materials  should  be  checked 
for  cracks  with  dye  penetrants.    All  metallic 
components 

should 

also 

be 

visually 

checked  during  these  inspections  for  signs 
of  corrosion.    If  a  component  shows 
evidence of cracking or loss of material due 
to  corrosion  it  must  be  replaced  with  a  new 
part. 
 
Continually  monitor  suction  and  discharge  
hose  assemblies  when  the  pump  is 
operating  for  leakage,  kinking,  abrasion, 
corrosion  or  any  other  signs  of  wear  or 
damage. 
 
Worn  or  damaged  hose  assemblies 
should be replaced immediately
.  At least 
every six months examine hose assemblies 
internally 

for 

cut 

or 

bulged 

tube, 

obstructions  and  cleanliness.    For  segment 
style  fittings,  be  sure  that  the hose butts up 
against  the  nipple  shoulder,  the  band  and 
retaining  ring  are  properly  set  and tight and 
the  segments  are  properly  spaced.    Check 
for  proper  gap  between  nut  and  socket  or 
hex  and  socket.    Nuts  should  swivel  freely.  
Check the layline of the hose to be sure that 
the assembly is not twisted. Cap the ends of 
the  hose  with  plastic  covers  to  keep  them 
clean  until  they  are  tested  or  reinstalled  on 
the  pump  unit.    Following  this  visual 
examination,  the  hose  assembly  should  be
