Its additional hydraulic stages provide increased lift while maintaining a maximum flow of 275 L\/Min.\u003c\/p\u003e\u003cp\u003eIts ZN6 construction uses AISI 316 stainless steel throughout the pump end, with AISI 316L stainless steel impellers and diffusers fitted with removable wear rings. A Duplex stainless steel UNS S 31803 shaft supports the rotating assembly, while the replaceable coupling is Duplex stainless steel UNS S 32304. The pump end is specified for suspended sand concentrations up to 100 g\/m³.\u003c\/p\u003e\u003cp\u003eWith a C4S motor, the combined installation is suitable for water temperatures up to 60°C and achieves a maximum head of 90 metres. Performance is specified to EN ISO 9906 Grade 3B, with delivery through the Rp 2 1\/2” (65 mm) threaded connection. A standard 4-inch NEMA motor connection allows coupling with the C4S submersible motor, with maximum immersion depth of 300 metres.\u003c\/p\u003e\u003cp\u003eThe microcast discharge head incorporates an integrated stainless steel non-return valve and dedicated holes for safety-hook attachment. Together with the lower support, the ASTM CF-8M (AISI 316 cast) discharge construction provides the specified arrangement for lowering and securing the pump end in deep borehole installations.\u003c\/p\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003eThe eight-stage radial arrangement provides the hydraulic lift required for deeper groundwater applications.\u003c\/li\u003e\n\u003cli\u003eRemovable wear rings allow the specified hydraulic clearances to be maintained through servicing.\u003c\/li\u003e\n\u003cli\u003eAISI 316L stainless steel impellers and diffusers form the hydraulic stages of the pump end.\u003c\/li\u003e\n\u003cli\u003eThe Duplex UNS S 31803 shaft is selected for the rotating assembly.\u003c\/li\u003e\n\u003cli\u003eThe Duplex UNS S 32304 replaceable coupling provides the specified motor connection component.\u003c\/li\u003e\n\u003cli\u003eAISI 316L tie rods and cable guard extend the stainless-steel construction through the external assembly.\u003c\/li\u003e\n\u003cli\u003eThe ASTM CF-8M microcast discharge head combines the lower support, non-return valve and safety-hook provisions.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e* Submersible motor sold separately - requires coupling and assembly\u003c\/p\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":51059136659703,"sku":"4ZN612\/8","price":5742.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn612-8-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller.png?v=1787570535","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn612-8-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
