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.\u003c\/p\u003e\u003cp\u003ePerformance 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.\u003c\/p\u003e\u003cp\u003eHydraulic 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.\u003c\/p\u003e\u003cp\u003eConstruction 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOpen channel impeller with cutting system for solids chopping\u003c\/li\u003e\n\u003cli\u003eCast Iron EN-GJS 600 impeller material for durability\u003c\/li\u003e\n\u003cli\u003eDouble silicon carbide mechanical seals for containment integrity\u003c\/li\u003e\n\u003cli\u003eStainless steel AISI 431 shaft with corrosion-resistant properties\u003c\/li\u003e\n\u003cli\u003eBi-epoxy 200 ?m sea water resistant coating on all cast iron\u003c\/li\u003e\n\u003cli\u003eHydraulic efficiency of 74.6% for optimised performance\u003c\/li\u003e\n\u003cli\u003eMaximum starts per hour: 20\u003c\/li\u003e\n\u003cli\u003eRequires accessory code 9024.114 for installation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Zenit","offers":[{"title":"Default Title","offer_id":50924036096247,"sku":"813547","price":13508.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/zenit-ctg550-4-80-cast-iron-high-flow-chopper-pump-for-sewer-systems-with-open-channel-impeller.png?v=1783508500","url":"https:\/\/foundationpumps.com.au\/products\/zenit-ctg550-4-80-cast-iron-high-flow-chopper-pump-for-sewer-systems-with-open-channel-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
