INSTALLATION AND USE

BC submersible pumps are suitable for draining dirty and sewage water in domestic and civil applications. They come equipped with a DOUBLE-CHANNEL stainless steel 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.

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: single-phase 220 V – 60 Hz
with thermal overload protector incorporated into the winding
BC: three-phase 380 V – 60 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, result- ing in an absolute insulation from moisture and water infiltration.
H07 RN-F” type (with Schuko plug for single-phase versions only)
Standard length:
– 5 metri for BC 10/50,
– 10 metri for BC 15/50, BC 20/50
