The Conforto STM / ST has a single impeller with axial suction and radial top discharge.
These pumps are suited to industrial, civil and agriculture applications, as well as water supply systems (maximum suction depth 7m) and heating. It is recommended that only chemically pure liquids, free of foreign matter, with a temperature below 80°C are pumped.
The STM / ST is a horizontal axis pump with a bronze impeller, the pump body and base support are made of G20 cast iron, with a AISI 416 stainless steel shaft and mechanical seal made of ceramic/ graphite. The impeller can also be made of Noryl with 20% glass fibre for models up to 1 HP.
The pump motor is a closed-type with external cooling fan, IP 44 safety class and F insulation. The single-phase motors are fitted with thermostat controlled safety micro switches, the three-phase motors require external capacitor protection (not supplied).
