Due  to  the  cost  of  energy  or  BHP 
necessary  to  overcome  the  friction 
generated  by  using  a  smaller 
diameter  pipe,  a  larger  diameter 

discharge  pipe  is  commonly  used 
than  the  required  by  the  volute  or 
body.

Installation & Operation

In  order  to  determine  the  optimal 
size of the piping, compare the total 
cost  of  the  equipment's  operation 

(cost 

of 

the 

pump, 

control 

equipment,  piping  and  energy 
consumption).  By  increasing  the 
discharge  diameter  reasonably,  it 

reduces the required BHP due to the 
low  friction.  Perform  different  tests 
using  several  piping  diameters  until 
you find the more convenient.

The  pipe,  valves,  etc.  should  be 
perfectly  align  with  the  volutes 
suction  and  discharge  centerlines, 

this  to  avoid  any  excessive  loads  on 

the  pumps  volute.  If  needed,  install 
new  expansive  joints  to  protect  the 
pump  from  excessive  thermal  or 

pressure forces.

Figure 6

Discharge piping.

Install  the  foot  valve  at  the  suction 

pipe (Figure 1) and fill with liquid the 
superior  part  of  the  pump´s  body. 
Sometimes  air  is  trapped  inside  the 
body, to remove it you should uncap 

the  male  plug  until  the  liquids  spills 
out. Re-install  the  male  plug  using  a 
sealant.

IMPORTANT!  -  Do  not 
operate  pump  without  
priming first. Operating dry 
will damage seal. 

Pre-Operation

1.

   C

heck  Voltage  and  Phase  - 

Compare  the  voltage  and  phase 

information  stamped  on  the 
pump name plate.

2.

   Check 

Pump Rotation -

 Improper 

motor rotation can result in poor 
pump  performance  and  can 
damage  the motor and/or  pump. 
Check  rotation  on  three  phase 

units  by  momentarily  applying 
power and observe the "kickback". 

4.

   P

riming -

 Every centrifugal pump 

must  be  primed  (suction  pipe  and 
pump´s  body  should  have  liquid), 
before operating.

Kickback  should  always  be  in  a 

counter-clockwise 

direction 

as 

viewed  from  motor  end  or  opposite 

to impeller rotation. Impeller rotation 
is  counter-clockwise  as  viewed  from 

bottom of pump.

3.

   N

ame  Plate  - 

Record  the 

information  from  the  pump  name 

plate  to  drawing  in  front  of  manual 
for future reference.
