Pumps

Halward Aqua Systems offers Pumps. These are vertical stainless steel in-line centrifugal pumps. These pumps come as skid mounted systems available in variable frequency drives (VFD), a very energy efficient system. The motor increases and reduces the pump speed accordingly to water and head requirement - making these ideal for hotels, hospitals, commercial complexes, high rise buildings, club houses, etc. Variable frequency drives system: the control panel shall drive 2 or 3 pumps, two on fix speed and one on variable speed. On start the variable speed shall start first. The transducer shall provide signal to the VFD pump in such a manner that as long as the consumption is within the capacity of one VFD pump, a constant pressure shall be maintained by varying the speed of the motor proportionate to the demand. Should the consumption be more one fix speed pump shall automatically cut in and the VFD pump shall adjust its speed automatically to maintain constant pressure.
