RECEIVING AND HANDLING
ACCEPTANCE
Thoroughly inspect this equipment before
accepting shipment from the transportation
company. If any of the goods called for in the
bill of lading or express receipt are damaged or
the quantity is short, do not accept them until the
freight or express agent makes an appropriate
notation on your freight bill or express receipt.
If any concealed loss or damage is discovered
later, notify your freight or express agent at once
and request him to make an inspection. We will
assist you in collecting claims for loss or damage
in shipment; however, this willingness on our part
does not remove the transportation company's
responsibility in reimbursing you for collection of
claims or replacement of material. Claims for loss
or damage in shipment must not be deducted
from the Reliance Electric invoice, nor should
payment of the Reliance Electric invoice, be
withheld awaiting adjustment of such claims, as
the carrier guarantees safe delivery.
If considerable damage has been incurred and
the situation is urgent, contact the nearest
Reliance Electric Sales Office for assistance.
Please keep a written record of all such
communications.
UNPACKING
If facilities for the shelter of equipment are not
available, repack motor and store shaft down
until ready for use.
After unpacking and inspecting to see that all
parts have been received in good condition, turn
the motor shaft by hand to be sure that there are
no obstructions to free rotation.
The motor should be checked for oil leaks after
being removed from the crate. If positive
indication of an oil leak is found around the shaft
seal or drive end bracket, notify the nearest
Reliance Electric Sales Office.
APPLICATION
All Reliance Submersible Pump Motors include
thermal devices as standard. These devices are
required by UL on all motors 1 HP and larger
listed Class I, Groups C and D. These devices
are not recognized by UL for motors less than
1 HP but are included by Reliance for additional
motor protection. Motors less than 1 HP are
supplied with a cautionary label and are
suitable on applications where vapor or gas
ignition temperatures exceed 280°C. These
motors are listed for Class I, Group D only.
Reliance Electric stocks common ratings
through 100 HP continuous duty submerged
in liquid, 15 minutes duty in air at nameplate
horsepower. Designs through 250 HP and
special continuous in air ratings are also
available. (Continuous in Air Designs have a
1.0 Service Factor.)
Normally, there are four conditions during which
a submersible sewage pump may be operated
in gases or vapors.
1. When the wet well is being dewatered.
2. When the pump motor assembly is being
lowered down the guiderails. The flow from
the pump is needed during the installation
process to insure that solids are cleared from
the discharge flange area to insure proper
seating.
3. When lowĆlevel cutoff controls fail.
4. When lowĆlevel sensors are positioned at the
bottom of the pump assembly.
NOTE: Outer shaft seal must be in liquid when
motor is operated, whether motor is submerged
or in air.
Seals cannot be run in a dry environment without
a significant reduction in seal life. If seal is to be
run in a dry environment, a special design seal
must be supplied. Standard seals applied in dry
seal applications will not be covered by warranty.
CONTINUOUS OPERATION GASES OR
VAPORS
