MSK2-90-44 - 4.0kW/400V - pump with a two -channel rotor with a 90 mm passage

MSK2-90 sewage pumps are intended for pumping sanitary and industrial sewage, as well as drainage and rainwater. They are used in sewage installations, sewage treatment plants and pumping stations and all kinds of dehydration. MSK2-90 are also excellent pumps for recirculation of sediments and process water in sewage treatment plants.
Free flight through the rotor channel of permanent bodies up to 90mm ensures trouble -free cooperation with DN200, DN250 and larger pipelines.
The pumps have a temperature limiter in three phases of engine stator windings and a moisture switch. These elements exclude the possibility of damage to the engine in the event of overloading or moisture into its interior.
The engine is sealed from the pumping unit with a double mechanical seal.
