A double mechanical shaft seal isolates the motor of the Calpeda MXSM 304CG, utilizing an oil chamber filled with oil for food machinery and pharmaceutic use. The close-coupled construction incorporates a chrome-nickel stainless steel AISI 304 external jacket and delivery casing. It features a float switch, built-in thermal protector, and triple impregnation humidity-proof dry winding.
Designed for water supply from tanks, the unit is utilized for domestic clean water transfer, rainwater harvesting, and garden irrigation. It handles liquid at temperatures up to 35°C in continuous duty scenarios. The compact 5-inch structure is compatible with narrow wells having a 140 mm minimum diameter.
Hydraulic output reaches a maximum flow rate of 75 L/min and a maximum head of 41.5 m. Powered by a 0.55 kW single-phase 240v motor drawing 4.1 Amps, the pumped liquid dissipates motor heat during operation. This permits safe operation during partial submersion in standing positions.
The hydraulic section incorporates multiple stainless steel impellers housed within stage casings to move clean liquid. An integrated suction strainer at the base prevents the entrance of solids with a diameter bigger than 2 mm, protecting the internal stages. The capacitor is incorporated in the float switch for ease of electrical configuration.
