The main feature of the O series is the oil bath motor. Together with its robust cast iron structure, it makes this model particularly reliable even in very tough operating conditions.
Simple and rational construction allows easy access for maintenance. As a result, even after its market launch in 1977, the O series continues to meet the requirements of the most demanding customers.
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.
