Zenit CTG750 5.50kW Three Phase Submersible Grinder Sewage Pump with Chopper Impeller (Max 2940LPM/200kPa)

The Zenit CTG750 5.50kW Three Phase Submersible Grinder Sewage Pump is a high-capacity commercial wastewater pump designed to handle heavily contaminated sewage and wastewater containing solids, rags, wipes, and fibrous materials. Featuring Zenit's advanced open channel chopper impeller and cutting system, the CTG750 efficiently cuts and shreds difficult waste before it enters the hydraulic passage, helping prevent blockages while maintaining exceptional pumping performance and reliability.

Designed for demanding municipal, industrial, agricultural, and commercial applications, the CTG750 combines the high flow capabilities of an open channel impeller with the superior solids handling performance of a vortex-style hydraulic design. Its heavy-duty cast iron construction, dual silicon carbide mechanical seals, integrated thermal protection, leakage monitoring, and corrosion-resistant epoxy coating ensure dependable operation and long service life in the harshest wastewater environments.
