BOOSTER SETS wITH VARIABLE SPEED with frequency inverter directly installed on each pump

 

Booster sets with 1-2-3 pumps (variable speed
by inverter mounted for each pump)
GENERAL DATA
Applications
Booster sets designed and built to ensure a constant pressure, specifically suita-
ble for domestic applications and small or medium systems for civil, agricultural or
industrial uses.
Booster sets strengths and benefit: constant pressure, low noise operation, low
running costs, low water consumption, protection against dry running.
Is recomended to use the sets with membrane pressure tanks.
Construction features
• Nr. 1, 2-3 electric pumps depending from the model of booster set (mecha-
nical seal, Hz 50)
• Base in painted steel (only for booster sets with more then one pump, for
single pump skid is not included)
• Suction and delivery galvanized steel manifolds, threaded (only for booster
sets with 2 or more pumps)
• Ball valves with union on suction and discharge of each pump (only for bo-
oster sets with 2 or more pumps, the single pump is supplied without on-off
valves)
• Check valve in to delivery of each pump
• Nr. 2 cast iron female plugs for closing manifolds (only for booster sets with
2 or more pumps)
• Nr. 1 electronic pressure transducer for each pump installed
• Sets supplied with membrane pressure tank connections
Electrical section
• Inverter module installed for each pump
• Electric protection control panel containing thermal magnetic (for pump only
supply not connected)
Inverter
The INVERTER module is a device installed on the pump, that includes a electronic
pressure transducer and an electronic inverter. Installed on the outlet discharger
line of each electronic pump, it controls the pump's speed rotation which is connec-
ted and maintain a fixed pressure at the setted flow rate variance.
Functioning
In case of pressure drop in/reduction, caused by water withdrawal, the first pump
start to satisfy at the requested flow rate. When the first pump reaches the maxi-
mum rotation speed the others pump (if present and necessary) start in cascading.
The pump pressure can be setted by the user with switches button on the inverter
(normally all pumps are setted at the same pressure level).
In parallel inverter installations (booster sets with two or three pumps), each inverter
controls and protects it’s pump and the operation is shared among all the connec-
ted pumps to average out pump wear. In case of failure, the remaining pumps will
maintain the pumping operation.
Each inverter also provides motor protection and monitoring , such as: protection
against overload and dry running, integrated soft-start and soft-stop functions, ex-
tending the life of the system and reducing peak absorption, indication of input
current and supply voltage, recording running hours and loggins errors and alarms
reported by the system, connect to other inverters to get combined operation. The
liquid cristal illuminated display ensures is easy to operate and a buzzer provides
an immediate indication of alarm.
Dry running signal via cosφ value
If pump runs dry, its cosφ value drops below a settable cosφ value, and the inverter
stops the pump after 2 seconds. Inverter will try to start the pump every 10,20,40,80
and 160 minutes, after which it will declare an alarm and stop the pump if the con-
dition persists.
In case of use under inverter and with membrane tanks, is necessary a total volu-
me of the tank (expressed in liters) not lower than the 10% of the maximum single
pump flow rate.
