Product Overview
Wastewater management across agricultural settings and municipal wastewater systems requires pumps that can handle solids and fibrous materials while maintaining high flow performance. The Zenit CTG 550/4/80 is a 4.0 kW submersible impeller chopper pump that integrates a high-speed chopper mechanism to shred solid filaments before they enter the high-efficiency open channel casing. The unit is suitable for heavy-duty commercial dewatering, municipal wastewater systems, and industrial sewage slicing and transfer.
Performance specifications include a maximum head of 18.5 metres and a maximum flow of 2400 L/Min, powered by a 415V three-phase motor drawing 8.4 Amps. The 4.0 kW motor uses direct starting with 49.3 Amps starting current and produces 26.7 Nm of rated torque. These characteristics suit high-volume applications requiring effective solids chopping 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 30 mm for processed material. Hydraulic efficiency is rated at 74.6%, with suction and discharge configurations of DN 100 (undrilled) and DN 80 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 Class H insulation, IP68 rating, thermal protection, and a leakage sensor. Cable length is 10 metres with 4G1,5+3x1 configuration, and the unit weighs 147.2 kg. An accessory (code 9024.114) is required for installation.
