The DT55KZN-H serves as a proven performer pumping muddy liquids and slurries across severe environments. It efficiently executes ground and nuisance water removal for subterranean tunnel and dam infrastructure.\u003c\/p\u003e\n\u003cp\u003eThe hydraulic drive utilizes a 5.5 kW motor connected to a 415v three-phase circuit, drawing a rated current of 11.5 Amps. Engineered as a high head slurry configuration, it develops an approximate maximum head of 17.5 metres. The system generates an approximate maximum flow rate of 1700 L\/Min via an 80 mm discharge port.\u003c\/p\u003e\n\u003cp\u003eAbrasive liquid handling is governed by a multivane semi-open impeller, processing solid concentrations up to 70 percent by weight. Positioned beneath the intake, a heavy duty high chrome agitator actively works the fluid, causing solids to move in suspension. This prevents clogging while passing 25 mm solids.\u003c\/p\u003e\n\u003cp\u003eTo combat relentless friction, the pump body is cast from FCD450 hardened ductile iron with extra thick walls rated at 300 Brinnell hardness. A 410 stainless steel shaft provides the rotational backbone alongside a high chrome iron suction cover. The IP68 rated assembly operates in 40 degree Celsius liquids.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInternal motor water jacket combined with a top discharge allows the unit to safely pump within inches of the bottom without overheating.\u003c\/li\u003e\n\u003cli\u003eHardened surface wear plate acts as a sacrificial component to inhibit performance-reducing erosion along the critical suction boundary.\u003c\/li\u003e\n\u003cli\u003eAbrasion resistant double silicon carbide mechanical seals reside within an isolated oil chamber for uncompromised motor protection.\u003c\/li\u003e\n\u003cli\u003eHeavy duty nitrile lip seal supplements the primary sealing arrangement by deflecting highly abrasive suspended grit.\u003c\/li\u003e\n\u003cli\u003eSleek vertical slimline design significantly minimizes the chance of damage to the outlet during transit or deployment down shafts.\u003c\/li\u003e\n\u003cli\u003eRemovable stainless steel shaft sleeves provide a highly economical replacement pathway to bypass premature central shaft wear.\u003c\/li\u003e\n\u003cli\u003eLarge open steel strainer physically blocks oversized destructive solids before they can enter the internal impeller cavity.\u003c\/li\u003e\n\u003cli\u003eHeavy duty lifting rings are securely mounted to the top shell for easy lifting and transportation of the pump.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Davey","offers":[{"title":"Default Title","offer_id":50868531364087,"sku":"DT55KZN-H","price":7470.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/davey-dt55kzn-h-ductile-iron-3-high-head-submersible-slurry-pump-for-tunnels-with-semi-open-impeller.png?v=1781669246","url":"https:\/\/foundationpumps.com.au\/products\/davey-dt55kzn-h-ductile-iron-3-high-head-submersible-slurry-pump-for-tunnels-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
