The system helps manage the continuous transfer of untreated effluents, providing predictable routing for facilities facing volatile sub-surface challenges.\u003c\/p\u003e\u003cp\u003eHydraulic mechanics are specifically tuned to deliver a maximum flow output of approximately 774 L\/Min combined with a maximum vertical head of 22.5 meters. Processing fluids through a 50 mm port, the system utilizes a single-vane semi-open impeller maintaining a rigid 30 mm free passage, helping to prevent the accumulation of fibrous materials.\u003c\/p\u003e\u003cp\u003eBuilt primarily from heavy-duty EN-GJL-250 cast iron, the external housing is designed to assist in preventing abrasive degradation. An intermediate non-toxic oil chamber serves as a dependable thermal buffer, intended to support the 1.5 kW three-phase 415v motor. This internal reservoir continuously lubricates the double shaft seal cartridge mechanism.\u003c\/p\u003e\u003cp\u003eWith a verified net weight of 42.0 kg, this explosion-proof certified unit operates securely within hazardous environments. It supports guide rail installations utilizing an automatic coupling base matching P\/N 97644486, permitting rapid extraction access without requiring personnel entry. A polyurethane potted cable plug tightly limits moisture intrusion.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eEngineered for a maximum safe hydraulic operating pressure of 6 bar\u003c\/li\u003e\n\u003cli\u003eVerified operational capability in continuous liquid temperatures up to 40 °C\u003c\/li\u003e\n\u003cli\u003eClassified strictly with IP68 enclosure protection and Class F insulation\u003c\/li\u003e\n\u003cli\u003eStandard electrical current consumption accurately rated at 3.8 Amps\u003c\/li\u003e\n\u003cli\u003eInternal multi-vane impeller structurally cast from EN-GJS-500-7 iron\u003c\/li\u003e\n\u003cli\u003eCapable of successfully managing up to 30 cyclic motor starts per hour\u003c\/li\u003e\n\u003cli\u003eFitted internally with long-life deep-groove greased ball bearings\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901029191927,"sku":"96104197","price":2779.93,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-ef30-50-15-ex-2-50b-cast-iron-explosion-proof-wastewater-pump-for-buildings-with-semi-open-impeller.png?v=1782722225","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-ef30-50-15-ex-2-50b-cast-iron-explosion-proof-wastewater-pump-for-buildings-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
