The Zenit GRG 300\/2\/G50H COET5 is a 2.2 kW submersible grinder pump with ATEX Zone 1 certification, featuring a high-efficiency grinder system with a high-speed rotary knife that slices particles before they reach the impeller. The unit is suitable for civil, residential, professional, and industrial applications including underground carparks and livestock farms.\u003c\/p\u003e\u003cp\u003eMaximum head reaches 29.9 metres with a maximum flow of 324 L\/Min, driven by a 415V three-phase motor drawing 4.6 Amps. The 2.2 kW motor uses direct starting with 28.2 Amps starting current and produces 7.3 Nm of rated torque. These performance characteristics suit medium-head applications requiring effective solids grinding and pumping.\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 a 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 before pumping. Hydraulic efficiency is rated at 49.4%.\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 43.2 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 fibrous waste 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 reliable sealing\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 49.4%\u003c\/li\u003e\n\u003cli\u003eDirect starting with 28.2 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":50924034490615,"sku":"807378","price":4665.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/zenit-grg300-2-g50hc0etex-cast-iron-grinder-pump-for-carpark-drainage-with-multi-channel-impeller.png?v=1783508494","url":"https:\/\/foundationpumps.com.au\/products\/zenit-grg300-2-g50hc0etex-cast-iron-grinder-pump-for-carpark-drainage-with-multi-channel-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
