lubricated units should be lubricated (refer to Section
III) to protect the bearings. Grease lubricated units are
lubricated at the factory during assembly. Turn the
rotor over by hand at least once a week to maintain a
protective film on the bearing components.
2.4.2
LONG-TERM STORAGE
More than precautions are required if long-term storage
in excess of 90 days from factory shipment is
unavoidable.
The internal surfaces of the pump should be sprayed
with a rust preventative such as a water soluble oil or
other suitable alternative. Particular attention should
be given to the impeller, wear plate and stuffing box.
An optional method of protection is to suspend bags of
desiccant material inside casing and completely seal all
openings from the surrounding atmosphere. The
stuffing box should be packed with clean. dry rags.
Use of this method requires that the casing be initially
free of liquid. The desiccant material should be
checked at regular intervals to ensure that it has not
absorbed excessive water vapour. A warning
instruction, advising that the desiccant must be
removed prior to installation should be wired to the
pump.
A rust inhibitor should be added to the lubricating oil of
oil lubricated units to give additional protection without
destroying the lubricating properties of the oil. For
specific recommendations, consult your lubrication
dealer. Grease lubricated units, which can be identified
by the grease fitting at each bearing location, should be
well lubricated prior to placing in storage. Small
amounts of additional grease should be added at
regular intervals during storage. Refer to Section III for
additional information related to grease lubrication.
Storage of pumps in areas of high ambient vibration
should be avoided to prevent bearing damage due to
brinelling. The risk of such damage can be reduced by
frequent rotation of the shaft.
The pump half coupling and key should be removed
from the shaft, coated with rust preventative and
wrapped to prevent metal-to-metal contact. Exposed
surfaces of the pump shaft should be protected with a
rust preventative. All dismantled parts should be
wrapped and tagged according to pump serial number
and a record kept of their location.
Pumps covered with plastic should
not be stored in a cool environment because
resulting condensation can cause rusting
.
2.5
Recycling and end of product life
At the end of the service life of the product or its parts,
the relevant materials and parts should be recycled or
disposed of using an environmentally acceptable
method and in accordance with local regulations. If the
product contains substances that are harmful to the
environment, these should be removed and disposed of
in accordance with current local regulations. This also
includes the liquids and/or gases that may be used in
the "seal system" or other utilities.
Make sure that hazardous substances are
disposed of safely and that the correct personal
protective equipment is used. The safety specifications
must be in accordance with the current local
regulations at all times.

PUMP DESCRIPTION
3.1
Configurations
Flowserve "FRBH" pumps are single stage, end
suction centrifugal pumps specifically designed for the
pulp and paper industry and consequently are ideally
suited to many process fluids. A volute type casing
with integrally cast feet and top centerline discharge
nozzle is standard. The semi-open impeller with rear
pump-out vanes is capable of passing pulpy material
and solids of a limited size. Sealing is provided at the
impeller to shaft fit to prevent corrosion and thereby
facilitate impeller removal. The rigid three point thrust
bearing housing support permits precision bearing
alignment. The back pull-out feature, typical of all
FRBH pumps, permits quick removal of the entire
rotor/frame assembly without disturbing the casing or
driver.
The pump is sealed using non-asbestos packing in the
stuffing box. An optional hydrodynamic seal,
commonly referred to as an expeller is available and
various mechanical seal designs as specified by the
customer may be installed at the factory or retrofitted in
the field.
All pumps are carefully inspected and prepared for
shipment. All exterior machined surfaces are coated
with a rust preventative compound and openings are
provided with covers or plugs. Shaft packing, when
required, is shipped loose with the pump and should
not be installed until the pump is ready to run.
Mechanical seals, when provided, are factory installed
and adjusted prior to shipment. The axial impeller
running clearance is preset at the factory but should be
checked prior to final alignment in case of tampering.
