1.3 Safety
1.3.1 General
Important!
The pump must not be used for other purposes than recommended and quoted for
without consulting your supplier.
A pump must always be installed and used in accordance with existing national and local
sanitary and safety regulations and laws.
• Always wear suitable safety clothing when handling the pump.
• Anchor the pump properly before start-up to avoid personal injury and/or damage to
the pump unit.
• Install shut-off valves on both sides of the pump to be able to shut off the in- and outlet
before service and maintenance. Check to see that the pump can be drained without
injuring anyone and without damaging the environment or nearby equipment.
• Make sure that all movable parts are properly covered to avoid personal injury.
• All electrical installation work must be carried out by authorized personnel in
accordance with EN60204-1. Install a lockable circuit breaker to avoid inadvertent
starting. Protect the motor and other electrical equipment from overloads with suitable
equipment. The electric motors must be supplied with ample cooling air.
In environments where there is risk of explosion, motors classified as explosion-safe
must be used, along with special safety devices. Check with the governmental agency
responsible for such precautions. Improper installation can cause fatal injuries.
• Dust, liquids and gases that can cause overheating, short circuits, corrosion damage
and fire must be kept away from motors and other exposed equipment. If the pump
handles liquids hazardous for person or environment, some sort of container must be
installed into which leakage can be led.
• If the surface temperature of the system or parts of the system exceeds 60°C, these
areas must be marked with warning text reading ”Hot surface” to avoid burns.
• The pump unit must not be exposed to rapid temperature changes of the liquid without
prior pre-heating/pre-cooling. Absolutely forbidden to flush a hot pump with cold water.
Big temperature changes can cause crack formation or explosion, which in turn can
entail severe personal injuries.
• The pump must not operate above stated performance.
• Before intervening in the pump/system, the power must be shut off and the starting
device be locked. When intervening in the pump unit, follow the instructions for
disassembly/assembly, section 4.0. If the instructions are not followed, the pump or
parts of the pump can be damaged. It will also invalidate the warranty.
• Impeller pumps must not be run dry. Dry running will create friction heat which will
damage the impeller and other parts sensitive to extreme heat. If there is a risk of dry
running, install a suitable dry running protection.
• If the pump does not function satisfactorily, contact your supplier.
1.2.3 Storage
A pump which is not installed immediately should be stored in a cool and dark room and
the impeller should be removed. The rubber material of the impeller ages and should be
treated as perishables. The storage should not exceed 2 years. If the pump has been
out of operation for a longer period of time, the impeller should be greased (for foodstuff
applications use appropriate food grease) before use to obtain optimal suction ability.

A.0100.301 – IM-FIP/08.00 EN (02/2014)
1.3.2 Pump units
1.3.2.1 Pump unit handling
Use an overhead crane, forklift or other suitable lifting device
Secure lifting slings around the front part of the
pump and the back part of the motor. Make sure
that the load is balanced before attempting the
lift. NB! Always use two lifting slings.
Warning
Never lift the pump unit with only one fastening
point. Incorrect lifts can result in personal injury
and/or damage to the unit.
1.3.2.2 Installation
All pump units should be equipped with a locking safety switch to prevent accidental start
during installation, maintenance or other work on the unit.
Warning
The safety switch must be turned to off and locked before any work is carried out on the
pump unit. Accidental start can cause serious personal injury.
The pump unit must be mounted on a level surface and either be bolted to the foundation
or be fitted with rubber-clad feet.
The pipe connections to the pump must be stress-free mounted, securely fastened to the
pump and well supported. Incorrectly fitted pipe can damage the pump and the system.
Warning
Electric motors must be installed by authorized personnel in accordance with EN60204-1.
Faulty electrical installation can cause the pump unit and system to be electrified, which
can lead to fatal injuries.
Electric motors must be supplied with adequate cooling ventilation. Electric motors must
not be enclosed in airtight cabinets, hoods etc.
Dust, liquids and gases which can cause overheating and fire must be diverted away from
the motor.
Warning
Pump units to be installed in potentially explosive environments must be fitted with an
Ex-class (explosion safe) motor. Sparks caused by static electricity can give shocks and
ignite explosions. Make sure that the pump and system are properly grounded. Check
with the proper authorities for the existing regulations. A faulty installation can lead to fatal
injuries.

the unit as well as cause personal injury.
1.3.2.4 Disassembly/assembly of the coupling guard
The coupling guard is a fixed guard to protect the users and operator from fastening and
injuring themselves on the rotating shaft/shaft coupling. The pump unit is supplied with
factory mounted guards with certified maximum gaps in accordance with standard
DIN EN ISO 13857.
Warning
The coupling guard must never be removed during operation. The locking safety switch
must be turned to off and locked. The coupling guard must always be reassembled after it
has been removed. Make sure to also reassemble any extra protective covers. There is a
risk of personal injury if the coupling guard is incorrectly mounted.
a) Turn off and lock the power switch.
b) Disassemble the coupling guard.
c) Complete the work.
d) Reassemble the coupling guard and any other protective covers. Make sure that the
screws are properly tightened.
1.3.2.5 Name plate – CE Declaration of Conformity
Always quote the article/serial number on the name plate together with questions
concerning the pump unit, installation, maintenance etc.
When changing the operating conditions of the
pump please contact your supplier to ensure a safe
and reliable working pump.

A.0100.301 – IM-FIP/08.00 EN (02/2014)
1.4 Function and operating principle
The impeller pump is designed for circulation, transport, emptying, filtration and dosing of
liquids.
The pumps are self-priming. The suction capacity is related to speed, viscosity and pipe
dimension. An untight suction pipe will reduce the suction capacity considerably.
The impeller pump can handle both high and low viscous liquids as well as liquids
containing solid particles, air and gases.
1.4.1 Operating principle
Due to the eccentric interior cross-section
of the pump body, a partial vacuum is
created as the volume increases between
the flexible impeller wings at the inlet port.
The resulting suction draws the liquid into
the pump.
The rotating impeller carries the liquid from
the inlet towards the outlet port. During this
part of the cycle, the volume between the
wings remains virtually constant. The
distance between the wings allows fairly
large solids to pass through the pump
without any harm being done to the liquid.
The liquid is discharged from the pump in
a continuous, uniform flow when the wings
bend, thus decreasing the volume between
them, as they come into contact with the
flattened part of the eccentric interior walls
of the body.
Liquids can be pumped in the opposite direction by reversing the rotation of the pump.

2.0 Technical information
Important!
The pump must not be used for other applications than recommended and quoted for
without consulting your supplier.
2.1 Dry running
Thanks to the self-priming ability of the pump it will only take a few seconds before the
pump starts to prime. The small amount of friction heat that is being created during these
few seconds will not damage the pump.
Bronze and stainless steel pumps can withstand a dry running period of 30 seconds
without damaging the impeller or the pump. Frequent dry running will however shorten the
service life of the impeller.
2.2 Pump body
2.2.1 Body executions
The FIP-range is available in 3 different
pump body executions:
• Hygienic stainless steel, AISI 316,
polished according to sanitary standards
• Stainless steel, AISI 316
• Bronze, dezincification resistant brass
2.3 Shaft material
• Hygienic stainless steel and industrial
stainless steel pumps are supplied with
double flat drive, stainless steel AISI 329
shafts. The double flat drive is designed
to avoid growth of bacteria in pockets of
stagnant media, and is easy to clean.
• Bronze pumps are supplied with splined
drive stainless steel AISI 329 shafts. The
splined drive ensures that the drive torque
is distributed evenly over an increased area
between the impeller and the shaft.

2.4 Shaft seals
2.4.1 Mechanical seals
Recommended for foodstuffs, solvents and
heavier chemicals. Only FDA mechanical seals
are approved for food applications. Delivered
as standard with seal surfaces in carbon vs
ceramic.
The mechanical seal for hygienic stainless
steel pumps are supplied with an extra O-ring
to seal off the area behind the stationary seal
part. This will allow easy cleaning with seal in
place, and eliminate liquid to remain behind the
seal. Only FDA O-rings are approved for food
applications.
2.4.2 Lip seals
Recommended for sticky and viscous liquids as
lip seals do not require as much lubrication as
mechanical seals.
2.5 Impellers
The impeller is a wearing part and the
performance of the pump will change with the
wear. Flow and pressure will be reduced with
the length of the duty.
Abrasive liquids will shorten the service life of
the impeller, and low speed is recommended.
With low speed, a constant flow will be
achieved during a longer period of time.
Following factors will effect the service life:
• Temperature, see next page
• The working pressure of the pump
• The speed of the pump
• Impeller material properties
• Lubrication properties of the liquid being
pumped

2.5.1 Liquid temperature and impeller life
The service life indicated below is based on several tests with water at 20°C at continuous
duty.
Continuous duty will not effect the service life of the impeller, but in installations with
frequent change of rotation, the service life of the impellers will decrease.
Neoprene end EPDM
• Temperature range +3° to +65°C
• When operating in the lower and upper areas of the indicated temperature range,
performance will be reduced and the service life of the impeller will be shortened
Nitrile
• Temperature range -15° to +65°C
• When operating in the lower and upper areas of the indicated temperature range,
performance will be reduced and the service life of the impeller will be shortened
For higher temperatures please consult your supplier.
2.6 Storage
A pump which is not installed immediately should be stored in a cool and dark room, and
the impeller be removed. The rubber material of the impeller ages and should be treated as
perishables. The storage should not exceed 2 years. If the pump has been out of operation
for a longer period of time, the impeller should be greased (for foodstuff applications use
appropriate food grease) before use, to receive optimal suction ability.

3.0 Installation, operation and maintenance
Note! See also section 1.3 Safety.
3.1 Pumping of foodstuffs
When pumping foodstuffs and other liquids with hygienic demands, the pump and the
system must always be drained and cleaned after every use.
3.2 Pumping of corrosive liquids
Corrosive and sometimes even relatively neutral liquids will attack the material of pump
and pump system. Draining and flushing of the pump and the system are recommended
after every use or after each working day. This is also recommended for liquids that has a
tendency to solidify at a lower temperature than the pumping temperature.
3.3 Installation and piping
• Anchor the pump unit and check that it is properly aligned.
• Install the pump closest possible to the tank to be pumped from.
• Use at least the same diameter of the pipes from and
to the pump as for the diameter of the in- and outlet
ports of the pump.
• If hose is used on the suction side, it ought to be
reinforced.
• Make sure that all pipes to and from the pump are
clean from scraps, slag and other particles that would
damage the pump.
• See to it that all pipe lines are correctly aligned with
the pump connections and unloaded to prevent
loads from being applied to the pump.
• Install shut-off valves on both sides of the pump to be
able to shut off the in- and outlet before service and
maintenance. Check to see that the pump can be drained without injuring anyone and
without damaging the environment or nearby equipment.
• Protect the pump from excessive pressure by installing a suitable safety valve in the
system. Install meters/sensors in the in- and outlet of the system to monitor the system.
• Check the rotation of the pump.
• If there is a risk of dry running, install a suitable dry running protection. Contact your
supplier for advice.
• All electrical installation work must be carrried out by authorized personnel in
accordance with existing regulations.
