The KSB UPA 300 submersible pump is a multistage vertical centrifugal pump engineered for deep well extraction and high flow water supply applications. Its body and impellers are manufactured from AISI 304 or AISI 316 stainless steel, providing excellent resistance to corrosion and abrasion. The pump features a nominal discharge diameter of 300 mm and can deliver flow rates up to approximately 850 m³/h with a maximum head of 450 meters. Bearings are water lubricated, and a multilayer mechanical seal minimizes leakage under high pressure operating conditions.
The UPA 300 is compatible with submersible motors ranging from 45 to 400 kW and is equipped with an IP68 protection class to ensure continuous underwater operation. Its mixed axial radial hydraulic design enhances efficiency and reduces vibration. This model is ideal for raw water transport, potable water supply, power plant utilities, large-scale irrigation, and desalination systems. The anti corrosion external coating and modular construction simplify maintenance and extend the operational lifetime.

The KSB UPA 300 submersible pump is engineered for deep-well installations with an operational depth of up to approximately 300 meters, providing stable pressure and suitable flow for agricultural and water supply systems. Its multistage hydraulic design and high-efficiency motor ensure continuous operation in temperatures ranging from 5 to 35 degrees Celsius and in water containing limited suspended particles. The stainless steel body and wear-resistant impellers allow long-term performance in corrosive environments. Ensuring sufficient bottom clearance for proper water circulation, preventing cavitation, and precise cable arrangement are key requirements for correct installation of this model.
