Zenit ZUGV080A7.5/2AWPAEX Cast Iron Heavy Duty Industrial Sewage Pump for Sludge Recycling with Vortex Impeller

Optimized for the management of sewage and the recycling of raw or activated sludges, this heavy-duty three-phase unit provides a professional wastewater handling solution. It is engineered to handle biological liquids and rainwater containing solids in civil and industrial treatment plants. The pump's industrial construction ensures long-term reliability in submerged wet installations for large collection basins.

Hydraulic performance provides exceptional lifting capacity, as the unit delivers a maximum head of up to 21.5 m and a flow rate of up to 2010 L/Min. Driven by a robust 7.5 kW three-phase motor configured for 415v power systems, it meets Premium Efficiency (IE3) class requirements. This model provides high stability across demanding discharge conditions for discharging soiled wastewater over significant elevations.

The vortex impeller creates an 80 mm free passage that allows solids and fibrous materials to pass with minimal impeller contact, reducing the likelihood of blockage while maintaining efficient wastewater transfer and smooth discharge flow. This hydraulic configuration maintains reliable liquid handling even when pumping heavily soiled civil wastewater containing larger suspended matter.

Mechanical design involves a durable cast iron EN-GJL 250 body and a high-strength AISI 431 stainless steel shaft, ensuring long-term alignment in submerged wet installations. Motor protection includes three bimetal thermal protectors (Klixon) and a leakage sensor, while two silicon carbide (SiC) mechanical seals protect the motor against liquid ingress. The entire assembly is coated with a thick 120 µm bi-epoxy layer to resist corrosion and chemical attack.
