DESIGN FEATURES
Motor housing, hydraulic part and impeller – cast iron EN GJL 200. Single mechanical seal – silicon carbide/silicon carbide on the hydraulic side in the oil chamber. The pumps are equipped with an asynchronous electric motor. The rotor rotates on oversized bearings filled with grease for life. A version with a moisture detection sensor in the oil chamber is available on request. Single-phase models can be equipped with a built-in float switch for automatic operation.
* Single-phase models are supplied complete with a starting capacitor unit that has built-in overload protection and an electrical power cable with a Schuko plug.
To protect the three-phase electric motor, overload protection must be provided in accordance with current regulations.
