procedure. 
 
Fluid end component inspections should 
be performed more frequently than every 
six  months  if  pressures  above  2500  psi 
are  used  in  the  discharge  system  or  if 
corrosive,  abrasive,  flammable  or  hot  
(over 110º F) fluids are being pumped.   
 
Proper  stuffing  box  packing  selection  is 
important for safe pump operation.  Contact 
a Gardner Denver service representative for 
assistance  in  selecting  the  proper  packing 
before beginning operation. 
 
Before  starting  the  pump  the  first  time,  and 
periodically  thereafter  check  the  pump, 
suction  and  discharge  system  fastener 
torques versus the values listed on page 12 
to  insure  proper  tightness.    Over  and under 
torquing  can  damage  threaded  pipes, 
connections  and  fasteners,  which  may  lead 
to  component  damage  and/or  failure.  
Replace  all  components  found  to  be 
damaged or defective.  On pumps equipped 
with  stuffing  boxes,  the  gland  must  be 
engaged by at least three (3) threads to hold 
the discharge pressure of the pump. 
 

 

 

DANGER 

 

Do  not  attempt  to  service,  repair  or 
adjust  the  plunger  packing  or  other-
wise work on the pump while the unit 
is  operating.  Shut off the pump drive 
engine  and  relieve  the  fluid  pressure 
in the suction and discharge systems 
before  any  work  or  investigation  is 
performed  on  the  pump  or  pump 
systems. 

 
 
Block the crankshaft from turning and make 
certain  that  all  pump  drive  motor  or  engine 
start  switches  or  starter  controls  are  clearly 
tagged  with  warnings  not  to  start  the  pump 
while repair work is in process. 

 
Whenever 

the 

pump 

is 

operating, 

continually  monitor  the  entire  suction, 
discharge  and  pump lubricating systems for 
leaks.  Thoroughly investigate the cause for 
leakage  and  do  not  operate  the  pump  until 
the  cause  of  the  leak  has  been  corrected.  
Replace  any  parts  which  are  found  to  be 
damaged  or  defective.    When  a  gasketed 
joint is disassembled for any reason, discard 
the  used  gasket  and  replace  it  with  a  new, 
genuine  Gardner  Denver  gasket  before 
reassembling the joint. 
 
Due to the high working pressures contained 
by  the  fluid  end,  discharge  manifold  and 
discharge 

piping, 

welding 

on 

these 

components  is  not  recommended.    If 
welding  on  the  discharge  system  cannot  be 
avoided, only experienced, qualified welders 
should be used.  In addition, the welded part 
should  be hydrostatically proof tested in the 
shop with water or hydraulic fluid to one and 
one  half  times  maximum  discharge  system 
working  pressure,  with  no  observable  fluid 
leakage,  before the part is reinstalled in the 
pump system. 
 
In summary, high pressure fluid streams can 
possess  sufficient  energy to cause personal 
injury,  death  and/or  equipment  damage.  
These  results  can  occur  either  through 
direct  contact  with  the  fluid  stream  or  by 
contact  with  loose  objects  the  fluid  stream 
has  propelled,  if  the  pump  system  is 
improperly  used,  or  if  the  fluid  is 
misdirected,  or  allowed  to  escape  from 
defective 

or 

improperly 

maintained 

equipment. 
 
FLAMMABLE, HOT, COLD OR 
CORROSIVE FLUID PUMPING 

 

 

 

DANGER 

 

Extreme  caution  must  be  exercised 
by trained and experienced operators 
when 

flammable, 

hot, 

cold 

or 

corrosive  fluids are being pumped to 
avoid  personal  injury,  death  an/or
