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.\u003c\/p\u003e\u003cp\u003eMaximum 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.\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 36 mm for processed material. Hydraulic efficiency is rated at 70%, with suction and discharge configurations of DN 150 (undrilled) and DN 100 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 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.\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 reliable containment\u003c\/li\u003e\n\u003cli\u003eStainless steel AISI 431 shaft for corrosion resistance\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 70% for optimised performance\u003c\/li\u003e\n\u003cli\u003eMaximum starts per hour: 20\u003c\/li\u003e\n\u003cli\u003eRequires accessory code 9024.091 for installation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Zenit","offers":[{"title":"Default Title","offer_id":50924036194551,"sku":"813548","price":16830.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/zenit-ctg750-4-100-cast-iron-open-channel-chopper-pump-for-construction-dewatering-with-open-channel-impeller_7b7c261e-ff97-4977-911b-7574932934ae.png?v=1783508500","url":"https:\/\/foundationpumps.com.au\/products\/zenit-ctg750-4-100-cast-iron-open-channel-chopper-pump-for-construction-dewatering-with-open-channel-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
