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".

Service

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

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.

Figure 4

Pressure  builds  up  extremely 
fast,  increase  pressure  by 
"TAPPING"  air  nozzle.  Too 
much  pressure  will  damage 
seal. 

DO NOT exceed 10 PSI.

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 
(20) then assemble to housing (4).

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.

Disassembly

Impeller, V-ring and Volute:

1. Disconnect power.

2. 

Remove 

capscrews 

and 

lockwashers,  vertically  lift  motor 
housing and seal plate assembly from 
volute. Clean out volute if necessary.

3. Inspect gasket and replace if cut or 
damaged.

4.  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.

5.  Check  v-ring  and  remove  if 
damaged.

Power Cord and Motor:

6.  Remove  pipe  plug  and  drain  oil 
from housing.

7.  Remove  gland  nut,  washer  and 
ring from housing. Pull cord through 
and  disconnect  the  wires  from  the 
terminals on power cord.

8.  Remove  screws  and  lift  motor 
housing and stator from seal plate.

Ÿ

If  oil  is  found  to  be  clean  and 
uncontaminated 

(measuring 

above  15  kV  breakdown),  refill 
the housing.

Ÿ

If  oil  is  found  to  be  dirty  or 
contaminated 

(or 

measures 

below  15  kV  breakdown),  the 
pump 

must 

be 

carefully 

inspected  for  leaks  at  the  shaft 
seal, cable assembly, square ring 
and  pipe  plug,  before  refilling 
with  oil.  To  locate  the  leak, 
perform a pressure test.

Pressure  Test  (If  oil  has  NOT  been 
drained)

  -  Oil  should  be  at  normal 

level.  Remove  pipe  plug  (20)  from 
housing  (4).  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.

10.  Check  motor  capacitor  with  an 
Ohm  meter  by  first  grounding  the 
capacitor  by  placing  a  screwdriver 
across  both  terminals  and  then 
removing  screwdriver.  Connect  Ohm 
meter (set on high scale) to terminals. 
If  needle  moves  to  infinity  (∞)  then 
drifts  back,  the  capacitor  is  good.  If 
needle  does  not  move  or  moves  to 
infinity  (∞)  and  does  not  drift  back, 
replace capacitor.

9. Remove v-ring, replace if damaged.
