Zenit DGG400/4/80HM0ETEX Cast Iron ATEX Submersible Pump for Process Wastewater Treatment with Vortex Impeller

Durable and efficient, this submersible pump is optimized for process wastewater treatment in industrial and civil drainage systems. It handles soiled liquids and sewage containing significant concentrations of suspended solids and fibrous matter. The unit is highly suitable for industrial process handling, civil lifting applications, and large-scale wastewater management systems.

Pumping capacity is provided by a 3 kW motor adjusted for a 415v supply, delivering balanced liquid movement for high-volume tasks. It delivers a flow capacity approx 1656 L/Min and reaches a vertical head upto 10.9 m. These performance values ensure the system meets high-volume transfer requirements typical of industrial process water networks.

The hydraulic system features a set-back vortex impeller integrated into the body, which helps reduce the risk of clogging when managing heavily polluted liquids. The configuration uses centrifugal force to move material away from the center of the pump, allowing solids to pass through the wide casing. This action ensures stable hydraulic performance when handling wastewater with fibrous materials and industrial waste.

Features Cast iron EN-GJL 250 construction for the casing and motor housing, providing a robust exterior resistant to abrasive operating environments. The drive assembly uses an AISI 431 shaft and double mechanical seals in silicon carbide (2SiC). ATEX certification ensures the pump is compliant for installation in Zone 1 hazardous atmosphere locations.

FEATURES
