3 SAFETY
3.1 Failure to comply with the safety regulations
NOTE!
Failure to comply with the safety regulations described in these Operating Instructions and common sense safety rules could
result in hazards to persons, the environment and the machine.
Specifically, this could lead to:
 failure of the machine and/or system to carry out key functions
 damage to the machine and/or system
 electrical, mechanical and/or chemical danger to persons
 environmental hazards caused by leakage of dangerous substances.
Failure to observe or comply with the safety regulations will invalidate warrant
ies and lead to loss of compensation for damages.
3.2 Startup, operation and maintenance
The plant of destination for the progressing cavity pump is not an integral part of the supply, consequently the customer is required to verify the
suitability of the machine for the specific requirements, to provide the process data necessary to ensure that the right pump is selected and to
ensure that any accessories required to guarantee the safety of the plant are included in the order. If the user maintains that certain accessories
he considers useful or essential have not been included in the Order Confirmation, it is the customer’s responsibility to inform the Manufacturer
and to request that the parts in question be installed on the machine.

4 DESCRIPTION OF THE PUMP
4.1 Main technical characteristics of the pump
The main characteristics of the pump are:
 uniform flow rate proportional to the rpm of the pump;
 minimum suction capacity of 4 mWC (NPSH), depending on the size, the number of stages and rpm of the pump;
 capacity to pump heterogeneous products, containing gases, abrasives, solid and fibrous materials in the liquid matrix;
 capacity for pumping high or low viscosity liquids;
 liquid metering capacity;
 pulse-free pumping with minimum tensile stress on the fluid;
 high pumping pressure of 6 bar per stage,
 1-2-4-and 8 number of stages depending on the required pressure .
4.2 Operating Principle
The progressing cavity pump is a self priming rotary positive displacement machine. The hydraulic part of the pump consists of a rotor (11 -
Fig.1) and a stator (12 - Fig.1).
The rotor, typically made of metal, is a single- or multi-start screw with round thread, extremely large pitch, considerable height and high
eccentricity in relation to the core diameter.
The stator, typically made of elastic material, is impressed with a cavity in the shape of a two or more start screw, double thread compared to
the rotor and with the same eccentricity.
The rotor, rotating within the stator, is forced to perform a hypocycloid roto-translational movement. This coupling of the two elements always
creates a line of contact along the profile that guarantees the seal between them. This movement creates an airtight chamber that shifts with a
helical movement, from the suction casing to the delivery casing.
The theoretical flow rate (Qt) is directly proportional to the number of revolutions of the pump and it can be calculated using the following
equation:
Qt = theoretical flow rate [m³/h]
D = rotor diameter [mm]
e = rotor eccentricity [mm]
P = rotor pitch [mm]
n = revolutions per minute [rpm]
The absorbed power is calculated using the following equation: ::
P = absorbed power [kW]
Q = flow rate [m³/h]
H = differential pressure [bar]
ɳ = overall efficiency (is the product of the volumetric efficiency and the mechanical efficiency)
In progressing cavity pumps the axis of rotation of the rotor does not coincide with the axis of rotation of the drive (3 - Fig.1). The rotor receives
motion from a double-jointed drive shaft (1 - Fig.1). The function of the rotating unit, consisting of drive shaft, hollow shaft (2 - Fig.1) and rotor, is
to transfer the torque given by the drive, support the eccentricity of the pumping unit (rotor + stator), bear the axial loads generated by back
pressure and the reaction generated by the roto-translation between rotor and stator.
4.3 Structure of the pump
For a description of the pump see Fig.1.
The pump can be coupled to the drive (3) with 2 types of coupling, defined as:
 type D: the drive is coupled directly to the coupling flange (4) and the hollow shaft (2); in this case the pump stress is absorbed by the
drive.
 type J: the bearing housing (6) is positioned between the drive (3) and the coupling flange (4). The drive is connected to the male shaft
with a flexible coupling fitted with a protective shield. The bearing support absorbs the pump stress and consequently increases its
reliability and sturdiness. This solution includes high performance bearings that require correct lubrication to work properly.
The pump can be made in various construction types, depending on the type of pump body (7) for pumps N and V or hopper for pumps H, HB,
HE, HP, HS. The HB and HP constructions include bridge breaker hopper with additional motor-driven product pushers. Various shapes and
sizes of connections are available, flanged or with quick couplings, terminal, threaded or special. Additional connections can also be made for
C.I.P. applications (Cleaning In Place).
The dimensions of each construction type of pump/hopper body are optimised for the type of fluid to be pumped guaranteeing suitability for high
viscosity fluids containing solids.
There are two joints (9) inside the pump body that enable the transmission of torque in presence of eccentricity. They are sealed with a rubber
protection and filled with oil to ensure perfect lubrication of the internal components.
The standard shaft has a single mechanical type seal (10), but the pump can also be configured with PTFE gland packing seals or double
mechanical seals. On request, cartridge or other types of seals can also be used. For both mechanical and gland packing seals suitable
housings are available for flushing the seals..
NOTE!
All variations must be defined and agreed with the Manufacturer at both the Offer and the Order Confirmation stage. The
operational limits of the pump are agreed at the Order Confirmation stage.

General description
4.4 Pump with bypass (optional)
The bypass (Fig.2) is an overpressure protection device. It consists of a valve (on request pre-calibrated or not), tubing and flanges which
connect the delivery casing to the suction casing. When the delivery pressure exceeds valve calibration pressure, the valve opens and the fluid
returns to the suction casing. The valve calibration pressure depends on process requirements, the type of pumped product and the number of
pump stages.
Fig.

–
Bypass operating principle
CAUTION!
The calibration pressure of the bypass valve must be agreed with the Manufacturer. The operating limits must comply with those
specified at the Order Confirmation stage.
With the bypass installed, the pump can only operate in one direction depending on how the bypass is installed, see
Fig.
2
.
4.5 Safety, pressure relief, check valves
The Manufacturer recommends installing the following devices:
 safety valve on the delivery casing to prevent operating pressures exceeding the pump’s specifications;
 check valve on the delivery casing to prevent return flow through the system.
NOTE!
If both a safety valve and a check valve are installed then the safety valve should be positioned closer to the pump than the
check valve.
4.6 Dry run protection
CAUTION!
Running the pump dry, even for just a few seconds, can ruin or even irreparably damage it.
When a continuous flow of liquid is not guaranteed, it is advisable to use special protection against dry running to protect the stator.
For pumps fitted with electric motors, a typical protection that prevents damage to the stator cause by lack of fluid, involves installing a
temperature sensor in the stator and connecting it to the electric panel that powers the motor. If fluid does not arrive, the rubber of the stator
overheats and increased temperature acts on the electrical circuit and shuts off the motor; this device can even be fitted after the pump has
been installed.
Alternatively, flow switches or other systems suitable for specific requirements can be used to directly control product presence; in this case
contact the Manufacturer.

how to correctly handle the pump. If in doubt contact the Manufacturer for more detailed instructions.
Once the packaging has been removed from the horizontal axis pump, it must only be lifted by means of the base (1 - Fig.6). The external fixing
holes or the eyebolts on the base (2 - Fig.6) can be used to lift it.
NOTE!
If the pump is not supplied with a base or eyebolts, use ropes. The ropes must be placed around the pump in such a way to
ensure a balanced lift (3 - Fig.6).

Handling and positioning
7.1.5 Instructions for subsequent handlings and positionings
Subsequent handlings and positionings differ depending on whether the machine is trolley-mounted or not.
7.1.6 For machines that are not trolley-mounted there are no particular instructions, simply refer to 7.1.4 - Instructions for handling and
positioning the pump.
For subsequent handlings and positionings, if the pump is trolley-mounted, proceed as follows:
 put the machine in “MAINTENANCE MODE” as described in 11 - Maintenance;
 verify that the machine is not connected to any plant;
 release the wheel brakes;
 shift the trolley-mounted pump manually, slowly and carefully, and position it in its new position;.
 apply the brakes to the wheels;
 return the machine to normal operating mode as described in 11 - Maintenance.
7.2 Unpacking and disposal of packaging materials
Packaging requirements are discussed and agreed with the Customer at the ordering stage. They can include:
 boxes;
 pallets;
 crates.
Once the pump has been unpacked, check that all machine parts are intact. Contact the Manufacturer if there is evidence of damage and/or
defects. Unpacking and disposal of the packaging are the responsibility of the Customer, who is required to comply with the applicable
