Pressure  Test  (If  oil  has  been 
drained)  - 

Remove  pipe  plug  from 

housing.  Apply  pipe  sealant  to 

pressure gauge assembly and tighten 
into  hole.  Pressurize  motor  housing 
to  10  PSI.  Use  soap  solution  around 

the  sealed  areas  and  inspect  joints 

for "air bubbles". 

After  leak  is  repaired,  dispose  of  old 
oil properly, and re ill with new oil.

f

Oil  Replacement -

 

  Set  unit  upright 

and refill with new cooling oil as per 

table below . Fill to just above motor, 
but  below  capacitor  as  an  air  space 
must remain in the top of the housing 

to  compensate  for  oil  expansion. 
Apply  pipe  thread  compound  to 

threads  of  pipe  plug  then  assemble 
to housing.

Oil Testing

Ÿ

Drain oil into a clean, dry container 

by  placing  pump  on  it’s  side, 

remove  pipe  plug  (20),  from 

housing (10).

Ÿ

Check oil for contamination using 
an oil tester with a range to 30 

 

kV 

breakdown.

Ÿ

If  oil  is  found  to  be  clean  and 

uncontaminated 

(measuring 

above 15  V breakdown), re ill the 

 

k

f

housing.

Ÿ

If  oil  is  found  to  be  dirty  or 
contaminated (or measures below 

 

15   breakdown), the pump must 

kV

 

be carefully inspected for leaks at 

 

the shaft seal, conduit box, o-rings, 

 

pipe  plug  and  pressure  valve, 
before  re illing  with  oil.  To  locate 

f

the leak, perform a pressure test.

 

Pressure  builds  up  extremely 

fast,  increase  pressure  by 

"TAPPING"  air  nozzle.  Too 
much  pressure  will  damage 
seal. 

DO NOT exceed 10 PSI.

Pressure  Test  (If  oil  has  NOT  been 
drained)  - 

Oil  should  be  at  normal 

level.  Remove  pipe  plug  from 
housing.  Apply  pipe  sealant  to 

pressure gauge assembly and tighten 
into hole. Pressurize motor housing to 
10 PSI. Use soap solution around the 
sealed  areas  above  the  oil  level  and 

inspect  joints  for  "air  bubbles".  For 
sealed areas below oil level, leeks will 
seep  oil.  If,  after  five  minutes,  the 

pressure is still holding constant, and 
no "bubbles"/oil seepage is observed, 
slowly bleed the pressure and remove 
the gauge assembly. Replace oil. Leek 

must  be  located  and  repaired  if 
pressure does not hold.

DO 

NOT

 

overfill 

oil. 

Overfilling of housing with oil 
can  create  excessive  and 

dangerous  hydraulic  pressure 

which  can  destroy  the  pump 

and create a hazard.

Overfilling oil voids warranty.

Cooling  Oil  - 

Anytime  the  pump  is 

removed from operation, the cooling 

oil  in  the  motor  housing  should  be 
checked  visually  for  oil  level  and 

contamination. To  check  oil,  set  unit 

upright.  Remove  pipe  plug  from 

housing.  With  a  flashlight,  visually 

inspect the oil in the housing to make 
sure it is clean and clear, light amber 

in  color  and  free  from  suspended 

particles. Milky white oil indicates the 

presence of water. Oil level should be 
just  above  the  motor  when  pump  is 

in vertical position.

Servicing

If,  after  five  minutes,  the  pressure  is 

still  holding  constant,  and  no 
"bubbles" are observed, slowly bleed 

the  pressure  and  remove  the  gauge 
assembly.  Replace  oil.  Leek  must  be 
located and repaired if pressure does 
not hold.

Disassembly & Assembly

Impeller  U-cup, V-ring  and Volute: 

Disconnect  power.  Remove  cap 
screws and lock washers vertically lift 
motor,  housing  and  seal  plate 
assembly  from  volute.  Clean  out 
volute  if  necessary.  Inspect  gasket 

and replace if cut or damaged. Check 
U-cup  for  damage.  If  replacement  is 
needed,  cut  the  U-cup  from  the 

volute  and  clean  surface  of  bore. 

Clean  and  examine  impeller,  for 
cracks  or  breakage  and  replace  if 
required. To remove impeller, place a 

flat screwdriver in the slot of the end 

of  the  shaft  to  hold  the  shaft 
stationary  while  unscrewing  the 
impeller.
