Product Overview
Wastewater management, construction, and industrial processing facilities require pumps that combine high flow rates with effective solids chopping for loaded wastewater streams. The Zenit CTG 750/4/100 is a 5.5 kW submersible impeller chopper pump featuring a high-efficiency open-channel hydraulic system with Vortex capabilities and hard-wearing active chopper cutting blades. The unit is suitable for a wide range of heavy-duty applications including wastewater management, agriculture, construction, and industrial processing.
Maximum head for this model is 20.0 metres with a maximum flow of 2982 L/Min, powered by a 415V three-phase motor drawing 11.5 Amps. The 5.5 kW motor provides consistent performance across the operating range, with Class H insulation and IP68 ingress protection. These performance characteristics suit high-volume applications requiring significant flow capability with moderate head requirements.
Hydraulic design incorporates an open channel impeller with cutting system, with the impeller manufactured from Cast Iron EN-GJS 600. The active chopper cutting system processes solids before they enter the impeller, with a free passage of 36 mm for processed material. Hydraulic efficiency is rated at 70%, with suction and discharge configurations of DN 150 (undrilled) and DN 100 respectively.
Construction features a Cast Iron EN-GJL 250 casing with bi-epoxy 200 ?m sea water resistant coating. The shaft is stainless steel AISI 431, and sealing uses two mechanical seals in silicon carbide (2SiC). Motor protection includes thermal protection and a leakage sensor. Cable length is 10 metres with 4G1,5+3x1 configuration, and the unit weighs 149.2 kg. An accessory (code 9024.091) is required for installation.
