DESIGN FEATURES
The hydraulic part is connected to the electric motor using a rigid coupling. Impellers and diffusers are made of NORYL technopolymer. The hydraulic housing, shaft with coupling, filter and cable protection strip are made of stainless steel. The support and pressure pipe are made of brass. The check valve is built into the hydraulics. The submersible asynchronous two-pole electric motor is entirely made of AISI 304 stainless steel with brass flanges. The copper squirrel cage rotor rotates on a Kingsbury thrust bearing. The thrust bearing block and bushings are cooled by a mixture of water and glycol, eliminating the risk of contamination. The starting capacitor unit for single-phase models has built-in overload protection. The closed stator housing is made of AISI 304 stainless steel, filled with thermosetting rubber with high insulating ability and excellent heat dissipation.
