Speroni 7.5 HP Multistage Submersible Pump SX 300-18 Specifications

This pump is configured for applications requiring a combination of high head and stable flow, reaching 117 m of delivery height while maintaining a maximum output of 300 l/min through an 18-stage design. Submersion capability extends to 150 m, with operational limits set at 35 °C liquid temperature and a sand tolerance of 50 g/m³. All main structural and hydraulic components, including the casing, motor shaft, stages, and impellers, are produced from stainless steel AISI 304 to maintain uniform material behavior under submerged conditions. Within the Speroni submersible pumps range, the SX 300-18 is positioned above lower-stage variants where additional lift is required without increasing flow volume. Compared to other Speroni multistage submersible pump configurations, this model emphasizes vertical pressure development driven by stage count, making it suitable for deeper installations where head height is the primary selection parameter rather than discharge capacity.
