Drainage submersible pump Dreno At 50/2/110 C.225 with two-channel impeller

Pump application: the BIC series is used for pumping clean water or light wastewater. The high hydraulic performance makes this series particularly suitable for pumping rainwater, surface water, ground water, lakes and rivers. Feature: the main components are made of GG20 cast iron in the standard configuration, a cuff seal is installed on the engine side, and a mechanical seal on the impeller side is also available on request in the new " EVO " version with a double mechanical seal at the rear located in the oil chamber. Motor range: 2-pole short-circuited rotor motor; thermal protection integrated in the winding; only for BIC PRO and AM-at 50/2/110, thermal protection T1 and T2 integrated in the motor winding (connected to the three-pole Contactor on the control panel); insulation Class F 155°; motor protection class IP68. Engine cooling: the engine is cooled by the liquid in which the pump is immersed. Limits of use: maximum permissible liquid temperature: 40°C when the pump is fully submerged; on request, special version (except ATEX); for BIC PRO and am-at 50/2/110 withstand liquid temperatures up to 60 ° C when the pump is fully connected, maintenance-free S1; maximum immersion depth: 20 m; permissible pH value: 6-10; hydraulic characteristics suitable for liquids with a density <1.1 kg / DM3; permissible voltage: 220v/380V ±5%; permissible frequency: 50 Hz ±2%.
