Zenit DGG750/2/80HA0FTEX Cast Iron ATEX Submersible Pump for Wastewater Lift Stations with Vortex Impeller

This professional submersible vortex pump is designed for wastewater lift stations and industrial and municipal wastewater applications. It transfers heavily soiled liquids in municipal infrastructure, livestock farms, and industrial wastewater treatment plants. The design provides hydraulic capacity in demanding environments with significant solid content.

Pumping capability is provided by a 5.5 kW motor configured for 415v, delivering consistent liquid movement for professional drainage duties. It achieves a maximum vertical head upto 16.1 m and maintains a maximum flow capacity approx 1680 L/Min. These metrics ensure reliable wastewater transfer in critical lifting and industrial infrastructures where high flow and discharge head are required.

The hydraulic design utilizes a specialized set-back vortex impeller to facilitate the passage of solids through centrifugal action. This design helps reduce the risk of clogging by ensuring that sewage and fibrous solids are moved away from the impeller center. This configuration maintains stable hydraulic performance even when handling heavily polluted soiled liquids.

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

FEATURES

• Set-back vortex impeller design creates an efficient flow path for solids and biological matter.
• 2-pole motor with Class H insulation and IP68 protection for continuous submerged service in industrial environments.
• Cast iron EN-GJL 250 construction for structural durability and weight for stability in lift stations.
