Replacement of vertical shaft pumps with amphibious pumps

Old scenario (year 2021)

Vertical Shaft Pumps (3 sets)

Maximum system flow: 2,304 m³/h(640 l/s)

Installed power: 1,050 HP (772.3 kW)

System pressure 48-50 mca

Power of each engine 350 HP(257.4 kW)

Flow per pump of 768 m³/h (213.3 l/s)

Hydro-energy index of 0.335 kW/m³/h

Monthly Electricity Cost R$ 205,714.00 (R$ 0.37kWh)

Customized study, design and installation according to site conditions;
Maximum system flow increased from 640 l/s to 1,005 l/s (+57%) with the same installed power;
Availability and operational guarantee with a reserve pump installed, where normal operation is carried out with only 02 units;
Modernization of equipment and elimination of existing maintenance problems in long-shaft systems;
Energy gain, with the cost of pumped water going from 0.335 to 0.213 kW/m³/h (-36%);
Projected annual savings of R$ 898,992.00 and a return on investment of 20 months.
