Loaded wastewater containing solids and fibrous waste in agricultural, construction, and industrial processing requires pumps with effective chopping and high flow capability. The Zenit CTG 1000/4/100 is a 7.5 kW submersible impeller chopper pump that combines Open Channel hydraulics with Vortex solids management capacity and an active chopper cutting system. The unit is suitable for heavy-duty applications across wastewater management, agriculture, construction, and industrial processing.
Performance specifications include a maximum head of 23.6 metres and a maximum flow of 3066 L/Min, powered by a 415V three-phase motor drawing 14.2 Amps. The 7.5 kW motor uses direct starting with a starting current of 21.3 Amps and produces 50.4 Nm of rated torque. These characteristics suit high-volume applications requiring significant flow capability with effective solids chopping.
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 34 mm for processed material. Hydraulic efficiency is rated at 69.9%, 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 Class H insulation, IP68 rating, thermal protection, and a leakage sensor. Cable length is 10 metres with 7G1,5+3x1 configuration, and the unit weighs 178.2 kg. An accessory (code 9024.091) is required for installation.
