INSTALLATION AND USE
BC-ST submersible pumps in stainless steel are recommended for draining dirty and sewage water in domestic, civil and industrial applications. They come equipped with a DOUBLE-CHANNEL impeller and are capable of pumping liquids containing short fibred suspended solids up to Ø 50 mm. They are ideal for pumping sewage, waste water, surface water and water mixed with mud in locations such as blocks of flats and detached houses. These pumps distinguish themselves for their reliability, which can be best appreciated under automatic operating conditions in fixed installations.

ISO 228/1
2| BASE| Stainless steel AISI 304
3| IMPELLER| Precision cast stainless steel AISI 304 DOUBLE-CHANNEL type. The
double-channel impeller produces ex-
cellent performance and high energy efficiency, developing higher pressure and
ensuring the pumping
of solids up to 50 mm in diameter. Definitely the most highly performing
solution for draining wastewater.

10 ELECTRIC MOTOR
Electric motors produced to a high quality standard, subjected to the most
rigorous checks to ensure excellent insulation. The im- pregnation of the
winding, achieved with high quality resins, is fol- lowed by treatment in an
oven for up to eight hours, thus ensuring the long working life of the motor.
BCm-ST: single-phase 230 V – 50 Hz with thermal overload protector
incorporated into the winding
BC-ST: three-phase 400 V – 50 Hz
Insulation: class F
Protection: IP X8
11 POWER CABLE
Power cable encapsulated in epoxy resin both in the area of the grommets
and at the point where the wires exit the sheath, resulting in an absolute
insulation from moisture and water infiltration.
