Zenit Group Products Applications Tools EN Account Zenit F Series electric submersible pumps The most compact ATEX certified range on the market, thanks to use of reliable materials and innovative technical features Previous Next F Series Range Details Specifications Accessories Downloads CONFIGURE YOUR PRODUCT › Home Products Electric submersible pumps F Series F Series electric submersible pumps The main feature of the F series models is ATEX certification, which allows them to be used where a standard submersible electric pump would be unacceptable due to the explosive nature of the liquids or environment. Every detail, from the cable to the metal fasteners, meets extremely high safety requirements to eliminate the risks inherent in use in potentially explosive atmospheres. They are available: with vortex impeller (DGF) with ample free passage, recommended for use with soiled liquids; multi-channel open impeller (DRF), intended mainly for lifting clean or lightly soiled liquids; with grinding system (GRF), suitable where there are fibres andfilaments in the wastewater; with high head (APF), intended for use with wastewater with sand and suspended abrasives. The mechanical seals are housed in a large, inspectable oil chamber to guarantee a long working life. The oil chamber can be fitted with an optional sensor connected to a special electrical panel to alert the user to any water seepage due to wear of the outermost mechanical seal in good time to allow it to be changed, preventing damage to the motor. Each model undergoes dual pressurised testing at the end of the line to ensure that the motor compartment is airtight and the mechanical seals have been correctly fitted, to guarantee excellent reliability.
