The Zenit GRG 400\/2\/G50H DOET5 is a 3.0 kW submersible grinder pump with ATEX Zone 1 certification, featuring a heavy-duty grinding mechanism that processes solid and fibrous waste. The unit is suitable for explosive gas atmospheres in industrial and municipal applications.\u003c\/p\u003e\u003cp\u003ePerformance specifications include a maximum head of 33.6 metres and a maximum flow of 288 L\/Min, powered by a 415V three-phase motor drawing 6.4 Amps. The 3.0 kW motor uses direct starting with 38.7 Amps starting current and produces 10.0 Nm of rated torque. These characteristics suit medium-flow applications requiring significant head capability with grinding performance.\u003c\/p\u003e\u003cp\u003eHydraulic design incorporates an open channel impeller with grinder system, with the impeller manufactured from Cast Iron EN-GJL 250. The grinder mechanism uses chromium steel cutter and cutting disk (X102 CrMo17 KU) that process all incoming solids. Free passage is 0 mm as all solids are reduced by the grinding system. Hydraulic efficiency is rated at 43.9%.\u003c\/p\u003e\u003cp\u003eConstruction consists of 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 45 kg. A ZENS9024.006 Ring Stand is required for free-standing operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOpen channel impeller with grinder system for solids processing\u003c\/li\u003e\n\u003cli\u003eChromium steel cutter and cutting disk X102 CrMo17 KU\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 coating on all cast iron components\u003c\/li\u003e\n\u003cli\u003eHydraulic efficiency of 43.9%\u003c\/li\u003e\n\u003cli\u003eMaximum starts per hour: 30\u003c\/li\u003e\n\u003cli\u003eRequires ZENS9024.006 Ring Stand for free-standing installation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Zenit","offers":[{"title":"Default Title","offer_id":50924034752759,"sku":"807379","price":5395.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/zenit-grg400-2-g50hd0etex-cast-iron-grinder-pump-for-industrial-effluents-with-multi-channel-impeller.png?v=1783508495","url":"https:\/\/foundationpumps.com.au\/products\/zenit-grg400-2-g50hd0etex-cast-iron-grinder-pump-for-industrial-effluents-with-multi-channel-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
