The Zenit DRG 300\/4\/80HG0ETEX is a 2.2 kW submersible drainage pump with ATEX Ex d certification, designed for industrial stormwater dewatering, wastewater treatment, and low to medium density activated sludge handling. The unit is compatible with both free-standing ring stand installations and fixed bottom coupling arrangements.\u003c\/p\u003e\u003cp\u003ePerformance specifications include a maximum head of 12.1 metres and a maximum flow of 1938 L\/Min, driven by a 415V three-phase motor drawing 5.2 Amps. The 2.2 kW motor uses direct starting with 25.3 Amps starting current and produces 14.9 Nm of rated torque. These performance parameters suit medium-flow dewatering operations where moderate head requirements are typical.\u003c\/p\u003e\u003cp\u003eSolids passage capability is provided by an open channel impeller with a free passage of 75 mm, one of the largest in this class. The multi-channel open impeller design maintains hydraulic efficiency while processing solids-laden liquids. The hydraulic system is manufactured from Cast Iron EN-GJL 250, with the impeller of the same material, and performance curve tolerance complies with UNI EN ISO 9906:2012.\u003c\/p\u003e\u003cp\u003eThe casing is Cast Iron EN-GJL 250 with bi-epoxy 200 ?m sea water resistant coating. A stainless steel AISI 431 shaft and two silicon carbide mechanical seals (2SiC) form the rotating assembly. Motor protection includes Class H insulation, IP68 ingress rating, thermal protection, and a leakage sensor. Cable length is 10 metres with 4G1,5+3x1 conductor configuration, and the unit weighs 60.2 kg. A ZENS9024.007 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 75 mm free passage for large solids handling\u003c\/li\u003e\n\u003cli\u003eHydraulic efficiency of 65.8% for optimised energy usage\u003c\/li\u003e\n\u003cli\u003eDouble silicon carbide mechanical seals for reliable shaft sealing\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 surfaces\u003c\/li\u003e\n\u003cli\u003eMaximum starts per hour: 30 for intermittent duty operation\u003c\/li\u003e\n\u003cli\u003eDirect starting with 25.3 Amps starting current\u003c\/li\u003e\n\u003cli\u003eRequires ZENS9024.007 Ring Stand for free-standing installation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Zenit","offers":[{"title":"Default Title","offer_id":50924032393463,"sku":"807390","price":5670.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/zenit-drg300-4-80hg0etex-cast-iron-drainage-pump-for-activated-sludges-with-multi-channel-impeller.png?v=1783508483","url":"https:\/\/foundationpumps.com.au\/products\/zenit-drg300-4-80hg0etex-cast-iron-drainage-pump-for-activated-sludges-with-multi-channel-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
