markings where non -observance of an instruction
would cause hazards. The specific safety markings
are:
This symbol indicates electrical safety
instructions where non -compliance would affect
personal safety.
This symbol indicates safety instructions where
non-compliance would affect personal safety.
This symbol indicates safety instructions where
non-compliance would affect protection of a safe life
environment.
This symbol indicates safety instructions
where non-compliance would affect the safe operation or
protection of the pump or pump unit.
This symbol indicates explosive atmosphere
zone marking according to ATEX. It is used in safety
instructions where non -compliance in the hazardous
area would cause the risk of an explosion.
This sign is not a safety symbol but indicates
an important instruction in the assembly process.
1.6.2 Personnel qualification and training
All personnel involved in the operation, installation,
inspection and maintenance of the unit must be
qualified to carry out the work involved. If the
personnel in question do not already possess the
necessary knowledge and skill, appropriate training and
instruction must be provided. If required the operator
may commission the manufacturer/supplier to provide
applicable training.
Always coordinate repair activity with operations and
health and safety personnel, and follow all plant safety
requirements and applicable safety and health laws
and regulations.
1.6.3 Safety action
This is a summary of conditions and actions to
prevent injury to personnel and damage to the
environment and to equipment. (For products used
in potentially explosive atmospheres section 1.6.4
also applies.)
PREVENT EXCESSIVE EXTERNAL
PIPE LOAD
Do not use pump as a support for piping. Do not mount
expansion joints, unless allowed by Flowserve in
writing, so that their force, due to internal pressure, acts
on the pump flange.
ENSURE CORRECT LUBRICATION
(See section 5, Commissioning, startup, operation and
shutdown.)
START THE PUMP WITH OUTLET
VALVE PART OPENED
(Unless otherwise instructed at a specific point in the
user instructions.)
This is recommended to minimize the risk of
overloading and damaging the pump motor at full or
zero flow. Pumps may be started with the valve further
open only on installations where this situation cannot
occur. The pump outlet control valve may need to be
adjusted to comply with the duty following the run-up
process. (See section 5, Commissioning start -up,
operation and shutdown.)
NEVER RUN THE PUMP DRY
INLET VALVES TO BE FULLY OPEN
WHEN PUMP IS RUNNING
Running the pump at zero flow or below the
recommended minimum flow continuously will cause
damage to the seal.
DO NOT RUN THE PUMP AT
ABNORMALLY HIGH OR LOW FLOW RATES
Operating at a flow rate higher than normal or at a flow
rate with no back pressure on the pump may overload
the motor and cause cavitation. Low flow rates may
cause a reduction in pump/bearing life, overheating of
the pump, instability and cavitation/ vibration.
NEVER DO MAINTENANCE WORK
WHEN THE UNIT IS CONNECTED TO POWER
HAZARDOUS LIQUIDS
When the pump is handling hazardous liquids care
must be taken to avoid exposure to the liquid by
appropriate siting of the pump, limiting personnel
access and by operator training. If the liquid is
flammable and/or explosive, strict safety procedures
must be applied.
Gland packing must not be used when pumping
hazardous liquids.
DRAIN THE PUMP AND ISOLATE PIPEWORK
BEFORE DISMANTLING THE PUMP
The appropriate safety precautions should be taken
where the pumped liquids are hazardous.
Page 5 of 54
FRBH, FRBHX AND FRBHS USER INSTRUCTIONS ENGLISH 71569178 10 -04
®
FLUORO -ELASTOMERS (When fitted.)
When a pump has experienced temperatures over 250
ºC (482 ºF), partial decomposition of fluoro -elastomers
(eg Viton) will occur. In this condition these are
extremely dangerous and skin contact must be
avoided.
HANDLING COMPONENTS
Many precision parts have sharp corners and the
wearing of appropriate safety gloves and equipment is
required when handling these components. To lift
heavy pieces above 25 kg (55 lb) use a crane
appropriate for the mass and in accordance with
current local regulations.
GUARDS MUST NOT BE REMOVED WHILE
THE PUMP IS OPERATIONAL
THERMAL SHOCK
Rapid changes in the temperature of the liquid within
the pump can cause thermal shock, which can result in
damage or breakage of components and sho uld be
avoided.
NEVER APPLY HEAT TO REMOVE IMPELLER
Trapped lubricant or vapour could cause an explosion.
HOT (and cold) PARTS
If hot or freezing components or auxiliary heating
supplies can present a danger to operators and
persons entering the immedi ate area action must be
taken to avoid accidental contact. If complete
protection is not possible, the machine access must be
limited to maintenance staff only, with clear visual
warnings and indicators to those entering the
immediate area. Note: bearing housings must not be
insulated and drive motors and bearings may be hot.
If the temperature is greater than 68 °C (175 °F) or
below 5 °C (20 °F) in a restricted zone, or exceeds
local regulations, action as above shall be taken.
1.6.4 Products used in potentially explosive
atmospheres
Measures are required to:
• Avoid excess temperature
• Prevent build up of explosive mixtures
• Prevent the generation of sparks
• Prevent leakages
• Maintain the pump to avoid hazard
The following instructions for pumps and pump units
when installed in potentially explosive atmospheres
must be followed to help ensure explosion protection.
Both electrical and non-electrical equipment must meet
the requirements of European Directive 94/9/EC.
1.6.4.1 Scope of compliance
Use equipment only in the zone for which it is
appropriate. Always check that the driver, drive coupling
assembly, seal and pump equipment are suitably rated
and/or certified for the classification of the specific
atmosphere in which they are to be installed.
Where Flowserve has supplied only the bare shaft
pump, the Ex rating applies only to the pump. The party
responsible for assembling the pump set shall select the
coupling, driver and any additional equipment, with the
necessary CE Certificate/ Declaration of Conformity
establishing it is suitable for the area in which it is to be
installed.
The output from a variable frequency drive (VFD) can
cause additional heating affects in the motor and so, for
pumps sets with a VFD, the ATEX Certification for the
motor must state that it is covers the situation where
electrical supply is from the VFD. This particular
requirement still applies even if the VFD is in a safe
area.
1.6.4.2 Marking
An example of ATEX equipment marking is shown
below. The actual classification of the pump will be
engraved on the nameplate.

1.6.4.3 Avoiding excessive surface temperatures
ENSURE THE EQUIPMENT TEMPERATURE
CLASS IS SUITABLE FOR THE HAZARD ZONE
Pumps have a temperature class as stated in the ATEX
Ex rating on the nameplate. These are based on a
maximum ambient of 40 °C (104 °F); refer to Flowserve
for higher ambient temperatures.
The surface temperature on the pump is influenced by
the temperature of the liquid handled. The maximum
permissible liquid temperature depends on the
temperature class and must not exceed the values in
the table that follows.
The temperature rise at the seals and bearings and due
to the minimum permitted flow rate is taken into
account in the temperatures stated.

The responsibility for compliance with the specified
maximum liquid temperature is with the plant
operator.
Temperature classification “Tx” is used when the liquid
temperature varies and when the pump is required to be
used in differently classified potentially explosive
atmospheres. In this case the user is responsible for
ensuring that the pump surface temperature does not
exceed that permitted in its actual installed location.
If an explosive atmosphere exists during the
installation, do not attempt to check the direction of
rotation by starting the pump unfilled. Even a short run
time may give a high temperature resulting from
contact between rotat ing and stationary components.
Where there is any risk of the pump being run against a
closed valve generating high liquid and casing external
surface temperatures it is recommended that users fit an
external surface temperature protection device.
Avoid mechanical, hydraulic or electrical overload by
using motor overload trips, temperature monitor or a
power monitor and make routine vibration monitoring
checks.
In dirty or dusty environments, regular checks must be
made and dirt removed from areas around close
clearances, bearing housings and motors.
1.6.4.4 Preventing the build up of explosive
mixtures
ENSURE THE PUMP IS PROPERLY FILLED
AND VENTED AND DOES NOT RUN DRY
Ensure the pump and relevant suction and discharge
pipeline system is totally filled with liquid at all times
during the pump operation, so that an explosive
atmosphere is prevented. In addition it is essential to
make sure that seal chambers, auxiliary shaft seal
systems and any heating and cooling systems are
properly filled.
If the operation of the system cannot avoid this
condition the fitting of an appropriate dry run protection
device is recommended (eg liquid detection or a power
monitor).
To avoid potential hazards from fugitive emissions of
vapour or gas to atmosphere the surrounding area
must be well ventilated.
1.6.4.5 Preventing sparks
To prevent a potential hazard from mechanical
contact, the coupling guard must be non -sparking and
anti-static for Category 2.
To avoid the potential hazard from random induced
current generating a spark, the earth contact on the
baseplate must be used.
Avoid electrostatic charge: do not rub non -metallic
surfaces with a dry cloth; ensure cloth is damp.
The coupling must be selected to comply with 94/9/EC
and correct alignment must be maintained.
1.6.4.6 Preventing leakage
The pump must only be used to handle liquids for
which it has been approved to have the correct
corrosion resistance.
Avoid entrapment of liquid in the pump and associated
piping due to closing of suction and discharge valves,
which could cause dangerous excessive pressures to

occur if there is heat input to the liquid. This can occur
if the pump is stationary or running.
Bursting of liquid containing parts due to freezing must
be avoided by draining or protec ting the pump and
ancillary systems.
Where there is the potential hazard of a loss of a seal
barrier fluid or external flush, the fluid must be
To avoid potential explosion hazards during
maintenance, the tools, cleaning and painting materials
used must not give rise to sparking or adversely affect

If leakage of liquid to atmosphere can result in a
hazard, the installation of a liquid detection device is
recommended.

1.8 Specific machine performance
For performance parameters see section 1.5, Duty
conditions. When the contract requirement specifies
these to be incorporated into User Instructions these
are included here. Where performance data has been
supplied separately to the purchaser these should be
obtained and retained with these User Instructions if
required.
1.9 Noise level
When pump noise level exceeds 85 dBA attention must
be given to prevailing Health and Safety Legislation, to
limit the exposure of plant operating personnel to the
noise. The usual approach is to control exposure time
to the noise or to enclose the machine to reduce
emitted sound. You may have already specified a
limiting noise level when the equipment was ordered,
however if no noise requirements were defined then
machines above a certain power level will exceed 85
dBA. In such situations consideration must be given to
the fitting of an acoustic enclosure to meet local
regulations.
Pump noise level is dependent on a number of factors the type of motor fitted, the operating capacity,
pipework design and acoustic characteristics of the
building. The levels specified in the table below are
estimated and not guaranteed.
The dBA values are based on the noisiest ungeared
electric motors that are likely to be encountered. They
are Sound Pressure levels at 1 m (3.3 ft ) from the
directly driven pump, for "free field over a reflecting
plane". For estimating LwA sound power level (re 1 pW)
add 14dBA to the sound pressure value.
If a pump unit only has been purchased, for fitting with
your own driver, then the "pump only" noise levels from
the table should be combined with the level for the
driver obtained from the supplier. If the motor is driven
by an inverter, it may show an increase in noise level at
some speeds. Consult a Noise Specialist for the
combined calculatio n.
& For units driven by equipment other than
electric motors or units contained within enclosures,
see the accompanying information sheets and
manuals.

2 TRANSPORT AND STO RAGE
2.1 Consignment receipt and unpacking
Immediately after receipt of the equipment it must be
checked against the delivery/shipping documents for its
completeness and that there has been no damage in
transportation. Any shortage and/or damage must be
reported immediately to Flowserve Pump Division and
must be received in writing within one month of receipt
of the equipment. Later claims cannot be accepted.
Check any crate, boxes or wrappings for any
accessories or spare parts that may be packed
separately with the equipment or attached to side walls
of the box or equipment.
Each product has a unique serial number. Ch eck that
this number corresponds with that advised and always
quote this number in correspondence as well as when
ordering spare parts or further accessories.
2.2 Handling
Boxes, crates, pallets or cartons may be unloaded
using fork -lift vehicles or slings dependent on their size
and construction.
The pump should be lifted with suitably sized and
located slings. Do not use the shaft for lifting and take
special care to prevent the pump from rotating in the
slings due to unbalanced weight distribution.
2.3 Lifting
A crane must be used for all pump sets in excess
of 25 kg (55 lb). Fully trained personnel must carry out
lifting, in accordance with local regulations. The driver
and pump weights are recorded on their respective
nameplates or massplates.
2.4 Storage
2.4.1 Short-Term Storage
When it is necessary to store a pump for a short time
before it can be installed, place it in a dry, cool location.
Protect it thoroughly from moisture and condensation.
Protective flange covers should not be removed until
the pump is being installed.
Wrap the exposed portions of the shaft and coupling to
protect against sand, grit or other foreign matter. Oil
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 prot ected 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.

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.
3 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 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.
3.2 Name nomenclature
The pump size will be engraved on the nameplate. The
following example explains how the pump name
identifies the construction features and options.

3.3 Design of major parts
3.3.1 Pump casing
The pump casing is a volute type casing with integrally
cast feet and top centerline discharge nozzle. It is a
one piece pressure retaining casting with gasket
connections to the stuffing box head and the suction
and discharge flanges.
3.3.2 Impeller
The impeller is semi-open design, keyed to the shaft
and secured with a contoured impeller nut. The vanes
of the impeller are Francis type however, the “S”
configuration utilizes straight radial vanes to reduce
blockage. The impeller of the FRBHS pump is recessed
away from volute to reduce shear.
3.3.3 Shaft
The large diameter stiff shaft, mounted on bearings,
has a keyed drive end.
3.3.4 Pump bearings and lubrication
Ball bearings are fitted as standard and may be either
oil or grease lubricated.
Oil lubrication is only available where the pump shaft is
horizontal.
3.3.5 Bearing housing
For oil lubricated bearings, a bulls eye level gauge is
supplied. Constant level oilers can also be fitted. Two
grease nipples enable grease lubricated bearings to be
replenished between major service intervals.

3.3.6 Stuffing box housing
The stuffing box housing has a spigot (rabbet) fit
between the pump casing and bearing housing for
optimum concentricity. The design enables a number
of sealing options to be fitted.
3.3.7 Shaft seal
The mechanical seal(s), attached to the pump shaft,
seals the pumped liquid from the environment. Gland
packing may be fitted as an option. The “FRBHX”
model is fitted with an optional dynamic or expeller seal
for certain applications.
3.3.8 Driver
The driver is normally an electric motor. Different drive
configurations may be fitted such as internal
combustion engines, turbines, hydraulic motors etc
driving via couplings, belts, gearboxes, drive shafts etc.
3.3.9 Accessories
Accessories may be fitted when specified by the
customer.
3.4 Performance and operating limits
This product has been selected to meet the specifications
of your purchase order see section 1.5. The following data
is included as additional information to help with your
installation. It is typical, and factors such as temperature,
materials, and seal type may influence this data. If
required, a definitive statement for your particular
application can be obtained from Flowserve.
3.4.1 Operating limits
Pumped liquid temperature limits up to+177 ºC (350 ºF)
Maximum ambient temperature up to +50 ºC (122 ºF)
Maxim um soft solids in suspension up to 7 % by volume
Maximum pump speed Refer to the nameplate
3.4.2 Speed torque curves
To bring a centrifugal pump up to rated speed, the
driver must be capable of providing more torque at
each speed than required by the pump. The margin
between the available and required torque affects the
time it takes the unit to reach full speed. If the torque
required by the pump exceeds the torque capability of
the drive at any run -up speed, the unit will not
accelerate to full speed. Normally, this is not a problem
with standard induction or synchronous motors
provided the proper voltage is supplied at the motor.
For pumps started at shut valve conditions, 100 percent
full speed torque can be calculated by using the
formula:
Torque (Nm) = 9545 Shutoff Power (kW)
r/min
Torque (lbfx ft) = 5250 Shutoff Power (hp)
r/min
Torque required by the pump at any other speed during
start-up can be determined from the curve above. Note
that the driver manufacturer usually bases 100 percent
torque on the design power of the driver and
consequently the speed-torque curves should be
plotted in torque units (e.g. Nm) instead of percentage
torque to avoid confusion.
