Operating Voltage Range: 3 phase 300V to 440V / 1 Phase 160V to 240V.
Maximum overall efficiency at duty point 415 Volt for Three Phase and 220 Volt for Single Phase.
Black shaded column shows maximum effieciency (output) at Duty Point.
Performance table shows the entire working range. so, It is always advisable to select the pumpset "accounting to operating head range" mentioned in the black shaded column.
All the above performance are bases on rated power supply 415 volt for three phase and 220 volt for single phase at 50 Hz.
Do not run pumpset in dry condition either for testing of for normal running.
As continues improvements / modification in the product are contemplated, product supplied may differ than the specification given.
"CORSA" reseves the rights to change specifications without prior notice.
Performance may very by 5 to 10% due to Voltage and frequency fluctuations and different pipe losses.
Installation depth should not be more than duty point head of pumpset.
Delivery pipe should be smooth internally and sufficient in size.
Each joint of the delivery pipe should be perfectly sealed to withstand high pressure of water.
USE E.C. Grade 3-core cable having sufficient size to minimize power loss.
Select proper starter panel according to H.P. of pumpset.
Black column indicates duty point head and discharge.
