With proper application and installation of
monitoring devices, periodic inspection of motor
seals is not required. Should a malfunction occur
the motor has been equipped with a moisture
detection system and thermal protection which
will provide advance warning of impending
failure allowing the user to plan a maintenance
program before failure occurs.
1. RelianceSubmersible Motors utilize an
explosionĆproof Class I, Groups C and D,
tandem seal design, with an oil chamber
separate from the winding area.
2. Wound Stators - Reliance Submersible MoĆ
tors utilize a wound stator which has been
pressed into the frame. The stator insulation
system has been designed for the temperaĆ
ture and electrical rating involved. If the motor
failure is analyzed to encompass a winding
failure, return the motor to an authorized ReĆ
liance Electric Service Shop.
3. Encapsulated Lead Connector Assembly -
The lead connector assembly has been
especially encapsulated to insure integrity of
the motor. The connector can be removed
from the motor in order to reconnect leads.
Should the lead connector assembly be
damaged or the integrity of the encapsulation
be in question, it is required that a replaceĆ
ment lead connector assembly be ordered
from Reliance Electric Company.

4. Hardware - All hardware is stainless steel
and should be replaced with the same type.
5. If the Conduit Connection is used, a corrosion
resistant conduit such as stainless steel is
recommended.
6. When replacement cable assembly is
required, order from Reliance Electric
Industrial Co. using motor identification
number.
U/L listed motors must be returned to an
authorized Reliance Electric Service Facility for
repairs other than to replace the outer seal. (See
note on Table of Content page.)
To inspect the outer seal proceed as follows:
1. Remove outer snap ring (3), replace as
needed.
2. Remove rotating outer seal (4), replace as
needed.
3. Approved lubricating and insulating oil shall
meet Reliance approved source sheet 4824Ć
18ĆAF. Manufacturer's materials currently
meeting this specification are as follows:

After assembly, run motor in shaft down position
for 30 seconds minimum to one minute
maximum to allow seals to seat; then check for
oil leakage. In some cases, a slight oil mist will
appear around the seal. Wipe clean after test.
Before painting motor, cover exposed seal.
Remove any paper, tape, etc., from seal area
before crating motor. These motors can be
shipped in shaft up or shaft down position. Care
must be taken that exposed seal is not damaged
during shipment. Carton must protect exposed
seal from dirt, dust and damage.
