Zenit CTG1000 7.50kW Three Phase Submersible Grinder Sewage Pump with Chopper Impeller (Max 3060LPM/235kPa)

The Zenit CTG1000 7.50kW Three Phase Submersible Grinder Sewage Pump is a heavy-duty commercial wastewater pump engineered for the reliable transfer of heavily contaminated sewage and wastewater containing solids, wipes, rags, and fibrous materials. Featuring Zenit's advanced open channel chopper impeller and integrated cutting system, the CTG1000 efficiently cuts and shreds difficult waste before it enters the hydraulic passage, minimising blockages while delivering exceptional hydraulic performance and operational reliability.

Designed for demanding municipal, industrial, commercial, and agricultural applications, the CTG1000 combines the high flow capabilities of an open channel impeller with the superior solids handling performance of a vortex-style hydraulic design. Heavy-duty cast iron construction, dual silicon carbide mechanical seals, integrated thermal protection, leakage monitoring, and a corrosion-resistant epoxy coating ensure long-lasting performance in harsh wastewater environments. The powerful 7.50kW motor utilises star-delta starting, reducing starting current while providing smooth, reliable operation in larger pumping installations.
