The Zenit GRG 550\/2\/G50H D0FT5 is a 4.0 kW submersible grinder pump with ATEX Zone 1 certification, featuring a robust cast iron construction designed for maximum reliability with a built-in high-head grinder system. The unit is suitable for livestock farm effluents, carparks, and explosive atmosphere environments.\u003c\/p\u003e\u003cp\u003eMaximum head for this model is 42.5 metres with a maximum flow of 270 L\/Min, driven by a 415V three-phase motor drawing 7.7 Amps. The 4.0 kW motor uses direct starting with 54.1 Amps starting current and produces 13.3 Nm of rated torque. These performance characteristics suit high-head applications requiring significant pressure capability for long-distance transfer or high elevation pumping.\u003c\/p\u003e\u003cp\u003eHydraulic design incorporates a multi-channel open 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 solids and fibrous materials. Free passage is 0 mm as all solids are reduced by the grinding system. Hydraulic efficiency is rated at 43.4%.\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 57.6 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\u003eMulti-channel open impeller with grinder system for solids reduction\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 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\u003c\/li\u003e\n\u003cli\u003eHydraulic efficiency of 43.4%\u003c\/li\u003e\n\u003cli\u003eDirect starting with 54.1 Amps starting current\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":50924034851063,"sku":"807380","price":6950.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/zenit-grg550-2-g50hd0ftex-cast-iron-high-head-grinder-pump-for-sewage-extraction-with-multi-channel-impeller.png?v=1783508496","url":"https:\/\/foundationpumps.com.au\/products\/zenit-grg550-2-g50hd0ftex-cast-iron-high-head-grinder-pump-for-sewage-extraction-with-multi-channel-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
