Speroni RA 5 RA 40 RA 50
Multi-impeller self-priming electric pump

Speroni RA - Three-phase Multiimpeller Self-priming Electric Pump

The Speroni RA electric pumps are multi-impeller self-priming pumps with horizontal axis which offer considerable pressure and a high water flow rate , while guaranteeing low energy consumption. Thanks to their silence and excellent hydraulic characteristics , these pumps are used in various sectors, including domestic systems , small sprinkler irrigation , vehicle washing and the assembly of booster sets such as autoclaves .

RA electric pumps have technical specifications that make them versatile and suitable for various uses. As regards the limits of use, they can operate with a liquid at a temperature of up to 35°C for domestic use according to the EN 60335-2-41 standard, while for other uses the maximum temperature allowed is also 35° C. The ambient temperature can reach up to 40°C , and the manometric suction height can reach 7 metres . Furthermore, these pumps are designed for continuous service .

The motor of the Speroni RA electric pumps is available both in the single-phase 230V-50Hz version and in the three-phase 230/400V-50Hz version. It is a 2 pole induction electric motor with a speed of 2850 RPM. The motor is Class F insulated and has IP 44 protection for the Speroni RA 5 models and IP 55 protection for the Speroni RA 40-50 models.
