| 1. Assign job number. |
2. Preliminary Inspection / Evaluation
If possible, all pumps
are checked for rotation and performance. Motors are
also checked for correct amperage and noise. Line cords
and switches are examined. All results are then recorded.
Please note: In many cases, pumps do not require
overhauls. Our philosophy and mission is to treat our
customers properly and to maintain our business ethics.
This means "if it's not broken, don't fix
it"! Somestimes all that is needed is a seal replacement,
flushing and/or minor cleaning. NOT necessarily a complete
"tear down"
|
3. On request, photos can be taken
and emailed to the customer for inspection.
Note: Our doors
are always open, and we invite our customers to visit
the shop. |
4.
Disassembly.
Nandor completely
disassembles each pump. This includes not just the pump,
but the removal of all guards, motors, pulleys and bases.
Every bolt and screw is removed for cleaning. The complete
unit / package is serviced. On units which are only
serviced, we also address these items!

5. Cleaning.
We do not use sandblasting!
Sandblasting creates tremendous heat and is very abrasive.
It can easily damage parts and is difficult to clean
hard to reach areas. Nandor's wet-blasting process,
even with various types of media, we are able to remove
all deposits, contaminants and paint without damaging
any of the surfaces. Even blind holes are thoroughly
cleaned! All pump parts including bases, guards,
pulleys etc. are cleaned and stripped using our cleaning
technologies. Motors are also cleaned and preped for
paint (if required).

6. Internal
inspection
All parts are visually
inspected for damage and tolerances. |
| 7. Quote generated and customer
contacted for approval. |
8. Prep for assembly (deburred & painted).
Prior to assembly (on
direct drive pumps) the housings, bases, motors are
painted. On belt drive pumps, the bases, guards and
pulleys are painted. It is more time consuming, however,
a "like new" appearance is obtained. There
is no oil whatsoever on the finished product. It is
extremely difficult to find a service facility that
will go to these lengths to ensure your pump not only
works as it should, but looks as it should! |
 |
9. Assembly.
We
meticulously check for any protrusions and ensure ease
of rotation throughout the assembly process. This eliminates
many unseen problems and premature failures.
|
 |
10. Testing.
Nandor tests the pumps
for a minimum of 24 hours. Most are tested for 48 hrs.
Pump pressures, temperatures and noise are checked and
logged. The pumps receive multiple oil changes (2-3).
We only use first generation oil in each of the changes!
This further ensures optimal performance and longevity.
|
 |
11. Pump wrapped for delivery
& shipping.
After final testing
and inspection, the pump is then tagged and clear wrapped.
By doing this our customer knows which pumps are ready
for service, and protects them from outside exposures.
When a pump is delivered, it goes back to the customer
with a FULL CHARGE of appropriate fluid! Should the
pump be shipped, it will be forwarded without fluid.
