This electric unit serves domestic and professional needs effectively, offering suitability for installation in IECEx Zone 2 hazardous areas requiring certified equipment. Its IECEx certification (Ex nA nC IIC T3 Gc) ensures compliance with international safety standards for environments where flammable vapours may accumulate.\u003c\/p\u003e \u003cp\u003eThis model delivers a maximum head of up to 17 m and a flow rate of up to 240 L\/Min, with the hydraulic system driven by a 0.74 kW electric motor. Operating on a standard single-phase 240v supply, it provides sufficient discharge pressure for residential elevations and civil wastewater disposal. The motor includes thermal protection, a starter box, starting capacitor and running capacitor to ensure reliable operation.\u003c\/p\u003e \u003cp\u003eAt its hydraulic core, a rotating chromium steel cutter works against a specialized cutting disk designed to cut fibrous materials and organic solids before they enter the hydraulic passage. The grinder system works in tandem with the open channel impeller to maintain efficient wastewater transfer. This design helps reduce the risk of blockages, ensuring that processed solids are transferred efficiently through the hydraulic flow path during standard duty cycles.\u003c\/p\u003e \u003cp\u003eThe structural assembly is built from heavy-duty EN-GJL 250 cast iron with an EN-GJS 600 foot base for high mechanical stability in wet installations. Motor protection is provided by a dual system of two silicon carbide (2SiC) mechanical seals, while the AISI 431 stainless steel shaft ensures long-term rotating alignment. A thick 120 µm bi-epoxy coating provides a protective shield over all internal and external cast iron surfaces against corrosion and chemical attack.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eIECEx Zone 2 certification (Ex nA nC IIC T3 Gc) ensures safe operation in hazardous environments requiring compliant equipment.\u003c\/li\u003e \u003cli\u003eHigh-strength grinder system with chromium steel cutters macerates organic solids and fibrous materials to reduce blockages.\u003c\/li\u003e \u003cli\u003eProfessional dual mechanical seal arrangement featuring silicon carbide (2SiC) provides protection for the internal motor housing.\u003c\/li\u003e \u003cli\u003eRobust cast iron EN-GJL 250 construction and EN-GJS 600 base offer structural integrity for submerged service.\u003c\/li\u003e \u003cli\u003ePrecision-engineered AISI 431 stainless steel shaft ensures high torsional strength and alignment of rotating elements.\u003c\/li\u003e \u003cli\u003eMotor protection includes thermal protection, starter box, starting capacitor and running capacitor for single-phase duty.\u003c\/li\u003e \u003cli\u003eThick 120 µm bi-epoxy coating protects internal and external cast iron surfaces from corrosion and chemical attack.\u003c\/li\u003e \u003cli\u003eThreaded G 1\"1\/2 discharge connection facilitates standardized integration with wastewater coupling systems and piping.\u003c\/li\u003e \u003c\/ul\u003e ","brand":"Zenit","offers":[{"title":"Default Title","offer_id":50925822738679,"sku":"711420","price":2664.75,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/zenit-grbluep100-2-g40hmex-cast-iron-iecex-grinder-pump-for-civil-wastewater-with-open-channel-impeller.png?v=1783578804","url":"https:\/\/foundationpumps.com.au\/products\/zenit-grbluep100-2-g40hmex-cast-iron-iecex-grinder-pump-for-civil-wastewater-with-open-channel-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
