Speroni RSM electric pumps are multi-impeller centrifugal electric pumps featuring a horizontal axis . These pumps are capable of generating considerable pressure and, at the same time, a high water flow rate with low energy consumption. Thanks to their great silence and excellent hydraulic characteristics , they are widely used in domestic systems , for small sprinkler irrigation , vehicle washing and for the assembly of pressure groups such as pressure tanks .
Speroni RSM pumps can work with a liquid at a maximum temperature of 35°C , according to the EN 60335-2-41 standards for domestic use . However, they can also be used in other applications with a maximum liquid temperature of 35°C . The ambient temperature in which these pumps can operate is up to 40°C .
The maximum manometric suction lift of these pumps is 7 meters . This means they can draw water from a depth of up to 7 meters below the pump itself, offering greater flexibility in applications.
Speroni RSM electric pumps are single-phase, 230V versions. They are powered by a 2-pole induction motor with a rotation speed of 2850 rpm. It features Class F insulation for greater safety. Furthermore, the motor is protected by an IP 55 enclosure, making it resistant to dust and splashes of water .
Regarding the materials used in the construction of Speroni RSM pumps, the pump body and motor support are made of cast iron , ensuring strength and durability over time . The impeller and diffusers are made of Noryl , a high-performance plastic material . The pump jacket and motor shaft are made of AISI 304 stainless steel. The mechanical seals used are of the silicon/silicon/NBR type, which offer good sealing and resistance to chemical agents.
