Comparison and gains
- 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.
