We are in need of four multistage centrifugal pumps that meet specific operational criteria. The pumps should operate efficiently within a range, starting from a minimum of 63 m³/h at a head of 580 m and achieving a design point of 75 m³/h at 640 m head, with a maximum capacity of 92 m³/h at 680 m head. Additionally, the pumps should be paired with 3-phase induction motors, suitable for VFD usage, operating at 400V, 50Hz. Key motor specifications include a 4-pole design, squirrel cage rotor, IE4 efficiency, and suitable cooling for operation above 38 Hz, all with an IP55 enclosure rating and dynamic balancing standards. Furthermore, we require a combined efficiency of at least 85% for both the pump and motor across the entire operating frequency range, which will be between 38 Hz and 60 Hz.
