This robust unit helps manage incoming fluid accumulation, maintaining stability during continuous submerged deployment in extraction setups.\u003c\/p\u003e\u003cp\u003eFluid dynamics within the volute are calibrated to handle a maximum flow rate of approximately 708 L\/Min alongside a maximum vertical head of 13.8 meters. The primary pathway utilizes a precision semi-open impeller maintaining a 10 mm free passage, developed to process particulates securely without causing internal blockages.\u003c\/p\u003e\u003cp\u003eConstructed from EN-GJL-250 cast iron, the primary housing assists in resisting abrasive wear. An intermediate oil chamber pre-filled with non-toxic oil is intended to support the 0.9 kW three-phase motor by providing thermal buffering. A double shaft seal cartridge facilitates field replacements without specialized hydraulic tools.\u003c\/p\u003e\u003cp\u003eRegistering a net weight of 44.5 kg, this explosion-proof machine is suitable for deployment in hazardous zones. The system supports guide rail installations utilizing an automatic coupling arrangement keyed to P\/N 97644486 to grant maintenance access without wet well entry. A hermetically sealed plug employs polyurethane potting to restrict ambient moisture.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eEngineered for maximum operating pressures reaching up to 6 bar\u003c\/li\u003e\n\u003cli\u003eOperational liquid temperature tolerance extending from 0 to 40 °C\u003c\/li\u003e\n\u003cli\u003eSpecified to securely handle up to 30 cyclic motor starts per hour\u003c\/li\u003e\n\u003cli\u003eStandard operational current load accurately specified at 2.8 Amps\u003c\/li\u003e\n\u003cli\u003eClassified strictly with an IP68 enclosure and Class F insulation\u003c\/li\u003e\n\u003cli\u003eInternal kinetic impeller components cast from EN-GJS-500-7 iron\u003c\/li\u003e\n\u003cli\u003eFitted internally with premium deep-groove greased-for-life bearings\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901026603255,"sku":"96104205","price":3067.71,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-dp10-50-09-ex-2-50b-cast-iron-explosion-proof-wastewater-pump-for-groundwater-with-semi-open-impeller.png?v=1782722193","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-dp10-50-09-ex-2-50b-cast-iron-explosion-proof-wastewater-pump-for-groundwater-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
