KSB UPA 350 submersible pump
The KSB UPA 350 submersible pump is a heavy duty multistage vertical centrifugal pump engineered for deep well extraction and high volume water supply applications. Its body, shaft, and impellers are manufactured from AISI 304 or AISI 316 stainless steel, providing outstanding mechanical strength and corrosion resistance. The pump features a 350 mm discharge diameter and, depending on the number of stages, can deliver flow rates up to approximately 1200 m³/h with a maximum head of 520 meters. Water lubricated bearings and a multilayer mechanical seal ensure stable and leak free performance under high pressure conditions. Its mixed flow hydraulic design enhances efficiency and reduces energy losses.
The UPA 350 can be coupled with submersible motors ranging from 75 to 500 kW, while its IP68 protection class enables continuous underwater operation. The dynamically balanced shaft minimizes vibration levels and increases bearing life. This pump is ideal for raw water transport, municipal water supply, power plants, large pumping stations, industrial irrigation, and desalination facilities. Its multi layer anti corrosion coating and modular construction simplify maintenance and significantly extend operational lifetime.
