Zenit Water Solutions

Professional/industrial pumps

For industrial and professional applications, Zenit electric submersible pumps are central to water recycling and disposal operations.

In lifting systems like pumping stations and first rainfall tanks, submersible pumps ensure that the water system functions properly.
Pumps with Grinder impeller are able to grind sludges and liquids containing solids.
These pumps have a number of main applications. In the civil sector, they are used above all by municipal authorities in water mains, for flood drainage and for maintenance and repair projects.

In construction and civil engineering, electric pumps are crucial for draining water from excavations and dense sludges from underground deposits.
In industry, they are able to process chemicals and abrasive and corrosive liquids.

These submersible electric pumps must guarantee high efficiency, performance and reliability standards.

This serie includes models with vortex impeller (DGO) which is recommended for use in soiled liquids and with multi-channel impeller (DRO) for lifting clean or slightly soiled water.
Each model undergoes pressurised test to ensure that the motor compartment is airtight and the mechanical seals are fitted correctly, to guarantee excellent reliability.

Zenit F Series electric submersible pumps

F Series

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.
