Zenit DGG300/4/80HE0ETEX Cast Iron ATEX Submersible Pump for Heavily Soiled Wastewater with Vortex Impeller

Optimized for handling heavily soiled wastewater and industrial drainage systems, this robust submersible pump is built for professional liquid management. It is a preferred choice for stormwater management, civil lifting stations, and commercial drainage where high solid content is present. The unit's design ensures efficient wastewater transfer through complex civil and industrial systems.

The motor delivers 2.2 kW of power rated for 415v, providing steady liquid movement across its four-pole configuration for constant drainage management. It achieves a maximum vertical head approx 11.0 m and maintains a flow capacity upto 1386 L/Min. These parameters provide effective pumping capability during peak demand periods in commercial and industrial systems.

Integration of a set-back vortex impeller helps reduce the risk of clogging by allowing solids and filaments to bypass the rotating parts. By creating a powerful centrifugal vortex, the hydraulic configuration moves polluted liquids without material making constant contact with the impeller vanes. This reduces mechanical stress and prolongs the service life of the hydraulic components.

Constructed from Cast iron EN-GJL 250, the casing and motor housing are treated with a 200 µm bi-epoxy coating for durability in abrasive operating environments. The internal drive system features an AISI 431 stainless steel shaft and double mechanical seals in silicon carbide (2SiC). ATEX certification ensures the unit is suitable for hazardous area installations where explosive gases may be present.
