Description
New version of the DC series completely designed and made even more reliable with the introduction of the double mechanical seal and the cataphoresis treatment of all cast iron parts.
The DC submersible pumps, built in cast iron of considerable thickness, exceptional strength, resistance to abrasion and durability over time, are recommended for draining clear or slightly dirty water.
They stand out for their robustness and reliability in fixed installations with automatic operation.
