N. Unpackaging
After receiving the pumping unit, inspect for
missing hardware, flange covers or possible
damage. In general, check to make sure the
shipment complies with the purchase order.
Inspect any parts containers that may be
shipped with unit (i.e. coupling, seals, etc.).
Immediately report any damage or shortage to
the carrier’s agent or factory. Claims that are
made at a later time cannot be accepted.
O. Packaging
If the pumping unit is sent back to Carver Pump
Company for repair, drain the unit, and re-seal
all flanges and connections that were covered or
plugged. Ship the pump(s) in an assembled
condition to prevent damage to sealing faces of
individual components. A Material Safety Data
Sheet (MSDS) is required on all returned
pumps. Copies of MSDS records should be kept
and maintained by the customer. The customer
is responsible for cleaning and flushing the
pump before it is returned to the factory. Make
sure to specify the fluid used in the service.
P. Inspection upon Arrival
NOTE
The pump and equipment, as shipped
from Carver Pump Company, have
adequate protection for short-term
storage. If the equipment is NOT
immediately installed and operated,
store the equipment in a covered, clean,
dry, well-ventilated location, free from
vibrations, moisture, and rapid or wide
variations in temperature.
Q. Storage of Pump
If the equipment is NOT immediately installed
and operated, Carver Pump Company
recommends rotating each shaft several
revolutions at least once every two weeks to
prevent flat spots on ball bearings.
Consider a unit to be in storage when any of the
following situations occur:
•
The pump has been delivered to the job site
and is waiting to be installed.
•
The pump has been installed but operation
is delayed pending completion of
construction.
•
There are long (30 days or more) periods
between operating cycles.
•
The plant (or department) is shut down for
periods of longer than 30 days.
caution
A pump which is made of cast or ductile
iron that sits in extreme heat, high
humidity, or full or partially full water
over 30 days will rust and will most likely
seize. If the pump rusts and/or seizes, a
complete overhaul and repair may be
necessary to refurbish the pump.
Storage requirements vary depending
on the length of storage, the climatic
environment, and the equipment. For
storage periods of three months or
longer, contact a representative from
Carver Pump Company for specific
instructions. Improper storage will
damage the equipment and will require
non-warranty restoration and/or non-
warranty product failures. Refer to
Section V, Maintenance and Repair, for
pump disassembly and assembly
procedures. When disassembling the
pump, replace and repair rusted parts,
as necessary.
R. Pump Protection during
Prolonged Shutdown
NOTE
If the customer anticipates that the
pump/equipment will be subject to an
extended period of storage after
installation, (for example, a unit used for
seasonal operation), contact a
representative from Carver Pump
Company. If this is the case, Carver will
provide specific instructions and special
protection for the equipment during the
extended period of storage. In general, if
a pump is to be shut down for an
extended period, the following steps are
recommended:
1. Shut down the pumping unit in
accordance with the Operating
Procedures outlined in this manual.
2. Shut off system suction and
discharge valves.
3. Drain the unit.
4. Fill unit with mineral oil or suitable
non-corrosive protectant that is
compatible with the system.
5. Provide pump and motor with a
protective cover.
