Pressure Boosting Sets
Fixed speed pump units
New electrical control panels
for fixed speed pump units.
New electrical control panels for pressurisation units, all with
electronic card with microprocessors, for managing pump
operation.

The microprocessor carries out continuous secure checks during

all the various work phases of the pumps and incorporates all
necessary functions, thus reducing electrical and electronic
components inside the panel.

In particular:
- pumps starting in a cascade sequence according to water
demand.
- changeover of pump starting sequence.
- delay start-up of the 2nd/3rd pump in case of breakdown of
pressure switch 1 or after a power cut.
- avoid pump starting in case of water hammering.
- activate the alarm when pressure 1 fails.
- activate the alarm when air cushion in the vessel drops.
- stop the pump when air cushion is over*.
* Patent pending

Maximum clarity for all signals

The status of the unit can easily be identified on the front of the
electronic card with the following signals:
- Power on led.
- No water led.
- Failure led.
- Pump running led (1 for each pump).
- Thermal block led (1 for each pump).
- Pump automatic operation led (1 for each pump).
- Pump stop led (1 for each pump).

Maximum simplicity of control

The front of electronic card features the following signals and controls:
- AUT-STOP push-button (1 for each pump)
- MAN push-button (1 for each pump)
- RESET push-button.

Optional remote control

The new panels have been designed to remotely reproduce all the electronic card signals (excluding the buttons), using RC 100 - RC 200 - RC 300
panels, connected with a simple two-pole cable.
The RA 100 panel enables a remote warning light and acoustic signal.

Control panel for units up to 6 pumps

Using the MPS 6000 (Multi Pumps System) electronic card it is possible to control pressure units up to a maximum of 6 fixed speed pumps with a
single pressure calibration.

Automatic air supply systems

The pump control panels are completed by microprocessor controlled systems for automatic air supply in the pressure vessels by means of a
compressor or solenoid valve.

Operation
For booster sets made up to three pumps: according to the pressure decrease in the system, the pressure switches make the pumps to start in
cascade mode and the starting changeover is made by the microprocessor.
For sets made of 4, 5, 6 pumps: Operation controlled by a microprocessor with signal from a pressure transducer. The pumps operate with only one
pressure setting.

Pressure Boosting Sets
Variable speed pump units with frequency converter

New electrical control panels

for variable speed pump units.
New electrical control panels for pressurisation units with variable
speed pumps.
These are indispensible in all those cases where constant pressure
is required and when high pressure pumps are being controlled.
All the various working phases are managed and controlled by the
MPS 6000 (Multi Pumps System) electronic card with microproces-
sor, which can operate up to 6 pumps working simultaneously.

Maximum clarity of signals

All the various calibration parameters appear as messages on the
display of the MPS 6000 electronic card.
If there are any faults or defects a message appears on the display
giving details of the problem.

Possibility of remote control

The pump status can be displayed and the unit can be controlled by
means of a special computer program.
It is possible to obtain a remote warning light and acoustic signal on
the RA 100 panel.

Constant or increased pressure

All the pumps can work with the same pressure value (set point), or, for
systems with high head losses, the pressure can be increased
depending on the number of pumps operating.

Silent operation
Motors working at reduced speed and check valves that close gradually mean that operation is particularly quite.

Long life for pumps

All the mechanical components of the pumps and motors are stressed to a minimum, due to the variable speed operation.

Energy savings
The motors consume only the precise level of power necessary moment to moment, in order to supply the quantity of water required by the system.

No more high capacity vessels

The use of inverters means that high capacity pressure vessels and membrane vessels are no longer necessary. Even units with high flowrate pumps
only require a small number of 20 litre membrane vessels.

Great versatility
The great versatility of the MPS 6000 electronic card enables the construction of special units with operational logics different from those of normal pres-
surisation units, depending on the requirements and characteristics of the systems.

Operation
Depending on water consumption, one or more pumps are activated, all at variable speed, in order to guarantee the quantity of water required at the set
pressure.

Pressure boosting sets for domestic use with two electric pumps
Fixed speed pump or Variable speed pump (frequency converter)

Construction
Automatic pressure boosting plant consisting of two pumps complete with ball, non return valve on the suction side and ball valves on the discharge
side.
Suction and delivery manifolds are in AISI 304 stainless steel.
Connections are located on the delivery manifold for the installation of two 20 litres cylindrical vessels.
Electrical control boards:
- with microprocessor for fixed speed pump units (see page 400).
- with frequency converter for variable speed pump units (see page 401).
The unit includes one pressure gauge and two adjustable differential pressure switches or pressure transducer (for sets with frequency converter).

Operation
BS 2F Fixed speed pump
Depending on the reduction of the pressure in the system, the pressure switches determine the starting up of the pumps in sequence and the
microprocessor alternates the starts.

BS1V1F Pumps at variable speed with one frequency converter

According to the water consumption, one or more pumps start, one at variable speed and the others at fixed speed, to grant the water
quantity required at the set pressure.

BS2V Pumps at variable speed with two frequency converter

Depending on water consumption, one or more pumps are activated, all at variable speed, in order to guarantee the quantity of water requi-
red at the set pressure.

Applications
For drawing water out a well.
As pressure boosting pump to increase water pressure when needed (follow local rules).

Motors
2-pole induction motors, 50 Hz, n = 2900 rpm.
- Three-phase 230/400V ± 10% up to 3 kW, suitable for operation with frequency converter;
400/690V ± 10% for 4 kW, suitable for operation with frequency converter;
- Single-phase 230 V ± 10%, with thermal protector.
Insulation class F.
Protection IP 54.
Constructed in accordance with: IEC 60034.

Construction
Automatic pressure boosting plant consisting of two vertical multi-stage close coupled pumps complete with ball, non return valve on the suction side
and ball valves on the discharge side.
Suction and delivery manifolds are in AISI 304.
Connections are located on the delivery manifold for the installation of two 20 litres cylindrical vessels (for 2MXV-B 25-32-40).
Connections are located on the delivery manifold for the installation of one 20 litres cylindrical vessel (for 2MXV-B 50).
Electrical control boards:
- with microprocessor for fixed speed pump units (see page 400).
- with frequency converter for variable speed pump units (see page 401).
The unit includes one pressure gauge and two adjustable differential pressure switches or pressure transducer (for sets with frequency converter).

Operation
BS 2F Fixed speed pump
Depending on the reduction of the pressure in the system, the pressure switches determine the starting up of the pumps in sequence and the
microprocessor alternates the starts.

BS1V1F Pumps at variable speed with one frequency converter

According to the water consumption, one or more pumps start, one at variable speed and the others at fixed speed, to grant the water
quantity required at the set pressure.

BS2V Pumps at variable speed with two frequency converter

Depending on water consumption, one or more pumps are activated, all at variable speed, in order to guarantee the quantity of water requi-
red at the set pressure.

Applications
To supply water in civil and industrial buildings.
As pressure boosting pump to increase water pressure when needed (follow local rules).

Motors
2-pole induction motors, 50 Hz, n = 2900 rpm
- Three-phase 230/400V ± 10%, suitable for operation with frequency converter.
- Single-phase 230V ± 10% (up to 2,2 kW).
Insulation class F.
Protection IP 54.
Constructed in accordance with: IEC 60034.
Other voltages and frequencies on request.

Construction
Automatic pressure boosting plant consisting of two vertical multi-stage pumps complete with ball, non return valve on the suction side and ball valves
on the discharge side.
Suction and delivery manifolds are in AISI 304.
Connections are located on the delivery manifold for the installation of two 20 litres cylindrical vessels (for 2MXV 25-32-40).
Connections are located on the delivery manifold for the installation of one 20 litres cylindrical vessel (for 2MXV 50-65-80).
Electrical control boards:
- with microprocessor for fixed speed pump units (see page 400). Motor starting is D.O.L. up to 5,5 kW and Y/∆ for power rating 7,5 up to 15 kW.
- with frequency converter for variable speed pump units (see page 401).
The unit includes one pressure gauge and two adjustable differential pressure switches or pressure transducer (for sets with frequency converter).

Operation
BS 2F Fixed speed pump
Depending on the reduction of the pressure in the system, the pressure switches determine the starting up of the pumps in sequence and the
microprocessor alternates the starts.

BS1V1F Pumps at variable speed with one frequency converter

According to the water consumption, one or more pumps start, one at variable speed and the others at fixed speed, to grant the water
quantity required at the set pressure.

BS2V Pumps at variable speed with two frequency converter

Depending on water consumption, one or more pumps are activated, all at variable speed, in order to guarantee the quantity of water requi-
red at the set pressure.

Applications
To supply water in civil and industrial buildings.
As pressure boosting pump to increase water pressure when needed (follow local rules).

Connections are located on the delivery manifold for the installation of two 20 litres cylindrical vessels (for 3MXV 50-65-80).
Electrical control boards:
- with microprocessor for fixed speed pump units (see page 400). Motor starting is D.O.L. up to 5,5 kW and Y/∆ for power rating 7,5 up to 15 kW.
- with frequency converter for variable speed pump units (see page 401).
The unit includes one pressure gauge and three adjustable differential pressure switches or pressure transducer (for sets with frequency converter).

Operation
BS 3F Fixed speed pump
Depending on the reduction of the pressure in the system, the pressure switches determine the starting up of the pumps in sequence and the
microprocessor alternates the starts.

BS1V2F Pumps at variable speed with one frequency converter

According to the water consumption, one or more pumps start, one at variable speed and the others at fixed speed, to grant the water
quantity required at the set pressure.

BS3V Pumps at variable speed with three frequency converter

Depending on water consumption, one or more pumps are activated, all at variable speed, in order to guarantee the quantity of water requi-
red at the set pressure.

Applications
To supply water in civil and industrial buildings.
As pressure boosting pump to increase water pressure when needed (follow local rules).

Motors

3 NM Pressure boosting sets with three Centrifugal Pumps
Fixed speed pump or Variable speed pump (frequency converter)

Construction
Automatic pressure boosting plant consisting of three centrifugal pumps complete with ball, non return valve on the suction side and ball valves on the
discharge side.
Suction and delivery manifolds are in steel.
Electrical control boards:
- with microprocessor for fixed speed pump units (see page 396). Motor starting is D.O.L. up to 5,5 kW and Y/∆ for power rating 7,5 up to 55 kW.
- with frequency converter for variable speed pump units (see page 397).
The unit includes one pressure gauge and three adjustable differential pressure switches or pressure transducer (for sets with frequency converter).

Operation
BS 3F Fixed speed pump
Depending on the reduction of the pressure in the system, the pressure switches determine the starting up of the pumps in sequence and the
microprocessor alternates the starts.

BS1V2F Pumps at variable speed with one frequency converter

According to the water consumption, one or more pumps start, one at variable speed and the others at fixed speed, to grant the water
quantity required at the set pressure.

BS3V Pumps at variable speed with three frequency converter

Depending on water consumption, one or more pumps are activated, all at variable speed, in order to guarantee the quantity of water requi-
red at the set pressure.

Applications
To supply water in civil and industrial buildings.
As pressure boosting pump to increase water pressure when needed (follow local rules).

Motors
2-pole induction motors, 50 Hz, n = 2900 rpm, suitable for operation with frequency converter.
- Three-phase 230/400V ± 10% up to 3 kW;
400/690V ± 10% from 4 to 55 kW.
