Horizontal multistage stainless steel pumps of the Speroni RSX/RSXM series have a design in which several impellers sequentially mounted one after another in a stainless steel casing, increase pressure from stage to stage. Pumps for the liquid transferring are capable to create the high pressure in water supply systems with relatively low electrical energy consumption. Pumps have good hydraulic characteristics and high capacity. Due to the low noise level during operation and excellent characteristics, the pumps are used in automatic domestic pressure boosting installations, water treatment systems, irrigation in agriculture and other industrial installations. The maximal working pressure is 10 bars. Liquid temperature up to 90 °C. The ambient temperature is not more than 40 ° C. The maximum suction depth is 7 m. 2-pole electric motor (2850 rpm), insulation class F, protection class IP55. The suction pipe and the engine caliper are made of cast iron. Impellers, diffusers, pump casing, motor shaft made of stainless steel. Mechanical mechanical seal graphite/ceramic.
