SECTION: SERVICE AND REPAIR

1) Lubrication:

Anytime the pump is removed from operation, the cooling oil 
in the motor housing should be checked visually for oil level 
and contamination.

1.1) Checking Oil:
Motor Housing -

 To check oil, set unit upright. Remove pipe 

plug from motor housing. With a fl ashlight, visually inspect the 
oil  in  the  motor  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.

1.2) Testing Oil:
1.) 

Place pump on it’s side, remove pipe plug, from

 

motor housing and drain oil into a clean, dry container.

2.)

  Check oil for contamination using an oil tester with a

 

range to 30 Kilovolts breakdown.

3.) 

If oil is found to be clean and uncontaminated

 

(measuring above 15 KV. breakdown), refi ll the motor

 

housing as per paragraph 1.4.

4.) 

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, cord

 

assemblies, square ring and pipe plug, before refi lling 

 

with oil. To locate the leak, perform a pressure test as per  

 

paragraph 1.3. After leak is repaired, dispose of old oil  

 

properly, and refi ll with new oil as per paragraph 1.4.

1.3)  Pressure Test:
Pumps  that  have  been  disassembled,  Motor  Housing  -

  If 

the  pump  has  been  disassembled,  the  oil  should  be  drained 
before  a  pressure  test,  as  described  in  paragraph  1.2. 
Remove pipe plug from motor housing. Apply pipe sealant to 
pressure  gauge  assembly  and  tighten  into  hole  (See  Figure 
1).    Pressurize  motor  housing  to  10  P.S.I.  Use  soap  solution 
around  the  sealed  areas  and  inspect  joints  for  “air  bubbles”.
If,  after  fi ve  minutes,  the  pressure  is  still  holding  constant, 
and  no  “bubbles”  are  observed,  slowly  bleed  the  pressure 
and remove the gauge assembly. Replace oil as described in 
section 1.4. If the pressure does not hold, then the leak must 
be located and repaired.

Pumps that have NOT been disassembled, Motor Housing- 

The pressure test may be done with the oil at its normal level.  
Remove pipe plug from motor housing. Apply pipe sealant to 
pressure  gauge  assembly  and  tighten  into  hole  (See  Figure 
1).  Pressurize  motor  housing  to  10  P.S.I.  Use  soap  solution 
around the sealed areas above the oil level and inspect joints 
for “air bubbles”. 

For sealed areas below the oil level, leaks will seep oil. If, after 
fi ve  minutes,  the  pressure  is  still  holding  constant,  and  no 
“bubbles”/oil seepage is observed, slowly bleed the pressure 
and remove the gauge assembly. If the pressure does not hold, 
then the leak must be located and repaired.

CAUTION ! Pressure builds up extremely 
fast, increase pressure by “tapping” air 
nozzle. Too much pressure will damage 
seal. DO NOT exceed 10 P.S.I.

1.4)  Replacing Oil:
Motor Housing- 

Set unit upright and refi ll with new cooling oil 

as per Table 1. Fill to just above motor as an air space must 
remain in the top of the motor housing to compensate for oil 
expansion. Apply pipe thread compound to threads of pipe 
plug then assemble to motor housing.

Important ! - For single phase units, oil level 
should be below capacitor

Warning ! - Do not overfi ll oil. Overfi lling of 
motor housing with oil can create excessive 
and dangerous hydraulic pressure which 

can destroy the pump and create a hazard. 
Overfi lling oil voids warranty.
