1. Safety
These operating instructions:
• must be considered as part of the product.
• must be read by the operator of the pump before placing it into operation and must be followed during operation.
• must be given to any subsequent owners or users of the product.
• must be updated by the user for any addendum received.
Warning! Chemical hazard!
These pumps have been designed to deliver a variety of liquids and chemicals. Please heed the notes regarding disposal
when performing maintenance and repairs.
Warning!
Safety risks for personnel mainly arise from improper use or accidental damages.
These risks may be of an electrical nature as far as the non-synchronous motor is concerned and may cause injury to
hands if working on an open pump. Risks may also arise due to the nature of the liquids pumped. It is therefore of utmost
importance to closely follow all the instructions contained in this manual so as to eliminate the causes that may lead to
pump failure and the consequent leakage of liquid dangerous for both personnel and the environment.
Risks may also arise from improper maintenance or dismantling practices.
In any case five general rules are important:
A) all services must be carried out by specialised personnel or supervised by qualified personnel depending on the type of
maintenance required
B) install protection guards against eventual liquid sprays (when the pump is not installed in remote areas) due to an accidental
pipe rupture. Arrange for safety basins to collect possible leakage
C) when working on the pump always wear acid-proof protective clothing
D) arrange for proper conditions for suction and discharge valve closing during disassembly
E) make sure that the motor is completely disconnected during disassembly
Proper design and building of the plants, with well positioned and well marked piping fitted with shut-off valves, adequate passages
and work areas for maintenance and inspections are extremely important (should the plant be faulty constructed or present wear-
and-tear defects, the pressure developed by the pump could lead to failure).
It must be stressed that the major cause of pump failures leading to a consequent need to intervene is due to the pump running
dry in manually operated plants. This is generally due to:
• the suction valve (if present) being closed at start-up or
• the suction tank being emptied without stopping.

• Transport (after the electrical leads have been disconnected by qualified personnel)
Actions that may be performed by trained personnel (technical abilities required: Knowledge of mechanical operations, the ability
to prevent damage during handling due to rubbing or impact, technical knowledge regarding fastening of screws and bolts on
various materials such as plastic/metal, use of precision measuring instruments:
• Opening and closing the pump casing
• Removing and replacing of rotating parts

6
1.4 Improper use
The pump is to be used solely to deliver liquids.
The pump cannot be used to generate isostatic or counter pressures.
The pump must not be used to mix liquids that undergo exothermic reactions.
The pump must be installed vertically in a stationary position.
The pump must be connected at the pressure port to a suitable hydraulic system with appropriate piping.
A shut-off mechanism independent of the pump must be installed in the system.
Handling of chemically aggressive liquids requires specific knowledge.
1.5 Disposal
Materials: Separate the plastic parts from the metal parts, and have them disposed of by an authorised company.

2. General
2.1 Field of application
Series B80 pumps are designed and built to transfer liquid chemical products with a specific gravity, viscosity, temperature and
stability of state appropriate for use with centrifugal pumps in a fixed installation, from a tank at a lower level to a tank or a pipe
at a higher level. The characteristics of the liquid (pressure, temperature, chemical reactivity, specific gravity, viscosity, vapour
pressure) and ambient conditions must be compatible with the characteristics of the pump and are defined when ordering. Impeller
and static casings, in contact with the liquid, are constructed from thermoplastic materials; other parts in high chemical-resistant
materials.
The performance of the pump (pump capacity, delivery head and rpm) is defined upon ordering and specified on the identification
plate.
Series B80 HME and KME pumps are single-stage vertical centrifugal pumps. The pumps are directly immersed in the liquid
to be pumped. Series HME is equipped with a cantilever shaft at the bottom part and can be operated beside the container in
a dry-well installation. They are connected by a rigid coupling to an electrical ansynchronous motor. The suction connection is
axially facing downwards. The pressure connection is positioned laterally and, if requested, can be equipped with a discharge
pipe for connection onto a piping (hydraulic) system outside of the tank. The support plate must be fastened to a rigid support
structure (see Installation instructions).
Series B80 pumps are not self-priming and as a consequence they must always start with the filled pump housing. Once the pump
has been started, the level must not drop below the minimum level in order to avoid the defusing of the pump (see Application
limits and Installation instructions).
Series B80 HME and KME pumps can run dry occasionally when liquid is absent, but not for periods longer than 15 minutes; to
resume pumping the pump body must be immersed.
Clockwise rotation seen from the motor side.
Make sure that the chemical and physical characteristics of the liquid have been carefully evaluated for pump suitability.
The maximum pressure that the pump can be subjected to is 1.5 times the maximum prevalence value. The pump must not
operate with the delivery closed
The submerged part (liner) must not be subject to lateral hydrodynamic thrusts by the liquid mass being moved.
The pump does not include any non return valve nor any liquid flow control or motor stop device.
When calculating the head, consider the actual level of the liquid in the suction tank and not the outlet connection.

8
2.2 Construction
The mechanical structure is extremely simple: the impeller is pulled in rotation by the pump shaft connected to the motor shaft
by a rigid coupling; the counter rotation of the impeller and a labyrinth reduce fluid leakage towards the shaft; dynamic loads,
usually reduced in this type of pump, are supported by the motor bearings.
The pump is supplied with a base plate to fasten it to the supports that must be pre-mounted on the system.
The discharge pipe, where it crosses the base plate, is provided with threaded collar (pipe clamp ring) and a lock nut which, by
fastening it to the plate, prevents the volute casing from being affected by mechanical stress from the system. It is abosolutely
necessary to reduce to a minimum any load on the connections. To do that, back the piping up with proper brackets in such a
way to allow thermal expansions (e.g.: expansion coupling, proper configuration).
The coated pump shaft, where it crosses the base plate, is provided with fume seal ring to protect the motor bearing and to reduce
fume dispersion in the environment in case of hot liquids.
2.3 Application limits
2.3.1 Ambient temperature
The range of permissible ambient temperatures depends on the type designation (specified on the identification plate):
0 - +40°C execution WR
-10 - +40°C execution FC
2.3.2 Maximum temperature of pumped liquid
The maximum temperature during continuous operation based on water depends on the type of materials chosen (see identifi-
cation plate).
70°C execution WR
90°C execution FC

GB
2.3.3 Immersion depth
To prevent sludge collecting at the bottom of the tank, the immersion depth can be increased by adding a suction extension (in
any case, ensure that the minimum distance from the bottom "S" is maintained). Should the extension pipe be greater than 250
mm in length, arrange for a bracket to keep lateral movement of the extension within 1 – 3 mm without blocking it whilst allowing
for thermal expansion at the same time. The maximum length of the extension pipe is 500 mm. The nominal bore must be the
same as that at the suction inlet.
2.3.4 Solids
The liquid being pumped may contain a maximum of 20 % of solid, non-abrasive particles not greater than 1 mm in size. The
presence of fibrous, adhesive or abrasive substances is not allowed. The maximum allowed size of objects occasionally present is
3 mm. For pumps with an FC type designation, the maximum concentration of metallic particles is 0.5 %, provided that their size
is less than 0.5 mm. Arrange for proper filtering or sedimentation stages to comply with the above-mentioned limits.
2.3.5 Specific gravity
The specific gravity that can be pumped at a temperature of 25°C (for liquid and ambient) depends on the diameter of the
impeller (shown on the identification plate) and the motor rating (shown on the motor identification plate) and has to be defined
when ordering.
2.3.6 Kinematic viscosity
The kinematic viscosity must not exceed 25 cSt so as not to significantly modify the performance of the pump. Higher values
up to a maximum of 75 cSt are possible provided that the pump is equipped with a suitable impeller and motor (to be specified
when ordering).
2.3.7 Vapour pressure
The vapour pressure value of the liquid to be pumped must exceed (by at least 1.5 m w.c.) the difference between the absolute
total head (suction-side pressure plus positive pressure head, or minus suction lift) and the pressure drops in the suction-side
piping (including the pressure drops across filters and the inlet NPSHr) drops shown on the specific tables.
2.3.8 Minimum delivery rate
The pump must not be allowed to deliver less than 5% of the maximum delivery rate.
2.3.9 External flushing
Flush out the pump at a flow rate of 100 l/h at a pressure of 1.5 bar.

10
2.4 Motor
2.4.1 Electrical connections
The pump’s direction of rotation, which can be verified by observing the cooling fan (in B80 pumps, the cooling fan must rotate
clockwise when viewed from above) is determined by the electrical connection to the terminals.
With single phase motors the direction of rotation may be
reversed by changing the position of the connection plates:
With three-phase motors the direction of rotation may be
changed by swapping any two of the three conductors inde-
pendently of the type of connection to the windings:
The windings of three-phase motors ( e.g. with (a) 230-400
V; (b) 400-690 V) require a delta-connection for lower voltage
( 230 volts for a ; 400 volts for b).
They require a star-connection for higher voltage (400 volts
for a; 690 volts for b).
Star/delta starting is used when the motor is rated above 7.5 kW (10 HP) only in the case of frequent starts and short running
times, but always when the motor is rated above 15 kW (20 HP). This is done to safeguard the pump.
2.4.2 Protection level
The initials IP are followed by two numbers :
The first number indicates the level of protection against penetration of solid objects and in particular :
4 for solids whose dimension is greater than 1mm
5 for dust (eventual internal deposits will not harm operation)
6 for dust (no pentetration)
The second number indicates the protection against the penetration of liquids. In particular:
4 for water sprays from all directions
5 for jets of water from all directions
6 for tidal and sea waves
According to the IP protection indicated on the identification plate of the motor and to the environmental conditions, arrange for
opportune extra protections allowing in any case correct ventilation and rapid drainage of rainwater.

3. Installation and operating instructions
3.1 Transport
• Cover the hydraulic connections.
• When lifting the unit, do not exert force on the plastic hydraulic fittings.
• Place the pump on its base or fixing plate during transport.
• If the road is particularly rough, protect the pump by means of appropriate shock-absorbing supports.
• Bumps and shocks may damage important working parts vital for safety and the functionality of the unit.
3.2 Storage
1) When it is necessary to store the pump prior to installation, don’t remove it from the original packaging. The packaged pump
must be stored in an enclosed, clean and dry environment.
2) If the pump’s packaging seems damaged upon receipt, inspect the pump to check its integrity. Place it in new packaging for
further storage.
3) Store the pump at an ambient temperature between -5°C and 40°C, and at a relative humidity below 80%. The packaged
pump must not be subjected to shocks, vibrations or other loads.
4) Check the condition of the grease in the bearing casing (support) prior to installation, if the pump has been stored for more
than 6 months. If necessary, add more grease.
3.3 Installation
• Arrange for a particularly rigid support structure: maximum deflection must be less than 0.2 mm based on the pump weight at
the installation site.
• Paint the support structure with epoxy enamel or a similar material to prevent corrosion.
• Arrange for adequate passage and install protective guards to protect personnel in compliance with applicable safety regulati-
ons.
• For motors, provide additional protection in the case of outdoor installation. Ensure proper air flow to the motor fan wheel and
that rainwater drains quickly.
• The tank under the pump must be covered appropriately in the case of hot liquids or liquids generating corrosive fumes (damaging
to metallic components of the pump outside the tank). Seal the base plate by means of thin, but not overly soft seals that are
well compressed by the fixing bolts.
• Do not use anti-vibration pads to mount the pump.
• Anti-vibration joints are recommended at the outlet pipe connection.
• Clean the system before connecting the pump.
• Make sure that no foreign bodies are left in the pump. Remove the safety caps from the hydraulic ports.

12
Follow the instructions indicated in the following diagram:
1) Install a shut-off valve on the discharge side.
2) Install a check valve (particularly with vertical or horizontal pipe runs; mandatory when pumps are connected in parallel).
3) Provide a connection point for a pressure gauge or safety pressure control device.
4) Secure all piping firmly. Use expansion joints (indispensable with long pipe runs or hot liquids).
5) Max. fluid speed on the pressure side: max. 3 m/s.
6) Install 45° bends in the pressure line to facilitate pump installation and removal. Do not attach elbows (or other fittings)
close to the pump (outlet or inlet).
7) Minimum suction head during start-up (see Dimensions); for suction head during pumping, (see Application limits).
8) A vertical suction extension for bottom suction lift is allowed (Not in order to empty the container completely).
9) Use a foot strainer (3-5 mm mesh screen), if solid matter (open tanks) or coarse impurities are present.
10) Arrange for drainage of liquids from the base plate.
11) Use all of the fixing holes to install the pump. The fixing points must be kept at the same level.
12) Maintain the minimum distance from the bottom and the walls (or other working pumps).

• Install extra protective guards for the pump and personnel as the need arises.
• Install an equivalent pump in parallel as a backup.

14
3.4 Start-up
• Verify that the instructions outlined in the installation section have been followed.
• Verify the correct direction of rotation (clockwise as seen from the motor end) by supplying the motor with short impulses.
• Ensure that the NPSH available is greater than that required by the pump (in particular with hot liquids, liquids with a high vapour
pressure, if a long suction extension is used or in the case of negative suction head).
• The suction pipe (if present) and the pump must be totally submerged.
• Start the pump with the discharge valve partially closed.
• Regulate the delivery rate by slowly opening the discharge valve (never by means of the suction valve) and make sure that the
current draw (power consumption) of the motor does not exceed the rated value indicated on the motor identification plate.
• Do not operate the pump at the limits of its performance curve: max. delivery head (discharge valve completely closed) or max.
delivery rate (total absence of delivery flow and geodetic head on the delivery circulation).
• Set the operating point to that for which the pump is intended.
• Ensure that there are no abnormal vibrations or noise due to inadequate mounting or cavitation.
• Avoid short and/or frequent starts by properly setting the control devices.
Motor rating (kW) 0.75 - 1.5 2.2 - 4 5.5 - 7.5 11 - 15 18.5 - 30 37 - 110
Max. starts/hour 36 28 20 15 10 6
Ensure that the temperature and pressure as well as the liquid characteristics are as specified at the time of order.

15
GB
3.5 Operation
• Switch automatic control on.
• Do not operate any valves whilst the pump is in operation.
• Risk of dangerous water hammer effects in the case of sudden or improper valve actuation (only trained personnel should
operate valves).
• Completely empty and clean the pump before using a different liquid.
• Isolate or empty the pump if the ambient temperature is the same or lower than the crystallisation temperature of the liquid.
• Stop the pump if the liquid temperature exceeds the maximum allowed temperature indicated in the "Application limits" section.
If the temperature exceeds this value by approx 20%, check the condition of internal parts.
• Close the valves in case of leaks.
• Wash with water only if compatible from the chemical point of view. As an alternative, use an appropriate solvent that will not
undergo any dangerous exothermic reactions.
• Contact the supplier of the liquid to be pumped for information on suitable fire-extinguishing measures.
• Empty the pump in case of long periods of inactivity (in particular with liquids which would easily crystallise).

16
3.6 Disassembly
• All of the following maintenance operations must be performed under the supervision of qualified personnel.
• Switch off power to the motor and disconnect the electrical leads. Remove the wires from the terminal box and cover the ends.
• Close the pressure valves.
• Wear gloves, safety goggles and acid-resistant clothing when detaching and washing the pump.
• Loosen the lines and allow enough time for any remaining liquid to drain out of the pump.
• Wash the pump before performing any maintenance work.
• Do not contaminate the environment with the used washing liquid.
• Lift the pump vertically, taking care to not exert any pulling forces on the immersion tube (column).
• Before attempting to dismantle the pump, ensure that the leads have been disconnected from the motor and that the motor
cannot be started accidently.
Now open the pump, observing the sequence given in the spare parts list, and follow the recommendations below:
• The nuts and bolts have right-hand threads.
• To access the impeller, remove the volute casing unthreading the screws that fasten it to the column.
Once the volute casing is open, the impeller must be disconnected, blocking the shaft on the opposite side (remove the motor
fan if necessary); proceed by unscrewing the ogive (right thread), the impeller is then axially unthreaded.
The shaft covering is axially unthreaded with the impeller.
To remove the column and shaft complete motor:
• Remove the locking screws of the half clamps (spare parts list pos.5) (see fig.1 below)
• Remove the two half clamps (pos.4) (fig.1)
• Unscrew the vapour seal counterface (pos.10) keeping the column locked (fig.2)
• At this point, unthread the column
• At this point, proceed with the removal of the shaft (unthread the locking screws of the rigid coupling (pos. 7)) or with the
removal of the upper cover terminal.
Alternatively, if it is only necessary to work on the electromotor
The disassembly of the immersed parts can be avoided (fig. 3):
• Remove the locking screws of the half clamps (pos.5)
• Remove the two half clamps (pos.4)
• Unthread the locking screws of the rigid coupling (pos. 7)

GB
3.7 Maintenance
• All of the following maintenance operations must be performed under the supervision of qualified personnel.
• Clean the filter elements regularly (every 2 - 30 days, depending on the liquid being pumped).
• Inspect the rotating parts of the pump regularly (every 1 - 6 months, depending on the liquid pumped and the operating con-
ditions). Clean, exchange or lubricate parts as necessary (see Recommendations).
• Check for proper functioning of the motor controls regularly (every 3 - 5 months, depending on the liquid pumped and the
ambient conditions). Proper operation of the controls must be assured. Efficiency must be guaranteed.
• Excessive current draw (power consumption) could be an indication of impeller problems.
• Unusual vibrations could be due to an unbalanced impeller (caused by damage or foreign bodies/deposits obstructing the
blades).
• Reduced pump performance could be due to an obstructed impeller or damage to the motor.
• Motor damage could be due to abnormal friction within the pump.
• Damaged parts must be replaced with new original parts.
• The replacement of damaged parts must be carried out in a clean, dry area.
3.8 Repairs
Before sending back the appliance, following must be observed:
• Residuals in the appliance can cause danger to the environment and human health. The appliance must be completely emptied,
rinsed and cleaned.
• Please advise which liquid has been pumped. A respective safety data sheet must be attached to the return consignment.
