VERSION
Wastewater pump as monobloc unit with submersible motor and electric connection cable. Submersible motor in pressure-resistant version, with internal sealed active cooling. The unit is filled with medicinal white oil. The motor seal on the shaft employs two bidirectional wear-resistant mechanical seals. Both seals are cooled and lubricated with medical white oil. The motor compartment is equipped with a terminal board. Two maintenance-free ball bearings are used for storage. Retrofit option of sealing chamber monitoring with pencil electrode for protection against penetrating moisture. The motor and pump components are made of grey cast iron. Shaft and connection elements are made of stainless steel. The motor is suitable for continuous duty (S1) under full load in immersed and completely non-immersed state.
