SPECIAL ALLOY Series electric submersible pumps

The DRX, DRY and DGX models are constructed in CF8_M (AISI 316) stainless steel and have multi-channel open impeller suitable for strained liquids (DRX) or for liquids with solids (DRY), and vortex impeller for soiled wastewater (DGX).
The oil-bath motor and dual mechanical seal cooled by the motor oil guarantee continuous service even in heavy-duty conditions. They are recommended for applications with corrosive and aggressive liquids, and can therefore be used for industrial plants in the chemical and pharmaceutical sector, or with seawater.

DRB and DGB electric pumps are constructed in aluminum-bronze and have multi-channel open impeller suitable for strained wastewater (DRB) and vortex impeller for soiled wastewater (DGX). The oil-bath motor and dual mechanical seal cooled by the motor oil guarantee continuous service even in heavy-duty conditions.
They are recommended for applications with seawater or brine, in the fish processing and livestock farming sectors.
