Zenit CTG550 4.00kW Three Phase Submersible Grinder Sewage Pump with Chopper Impeller (Max 2280LPM/185kPa)

The Zenit CTG550 4.00kW Three Phase Submersible Grinder Sewage Pump is a premium heavy-duty wastewater pump designed to reliably handle heavily contaminated sewage and wastewater containing solids, rags, wipes, and fibrous materials. Equipped with Zenit's advanced open channel chopper impeller and cutting system, the CTG550 efficiently cuts and shreds difficult waste before it enters the hydraulic passage, dramatically reducing the risk of blockages while maintaining outstanding hydraulic performance.

Combining the high flow capabilities of an open channel impeller with the superior solids handling of a vortex-style hydraulic design, the CTG Series is built for continuous operation in demanding commercial, industrial, municipal, and agricultural environments. Featuring robust cast iron construction, dual silicon carbide mechanical seals, integrated thermal protection, leakage monitoring, and a corrosion-resistant epoxy coating, the CTG550 delivers dependable performance and a long service life in harsh wastewater applications.
