Its radial hydraulic arrangement provides the required lift while maintaining a maximum flow of 275 L\/Min.\u003c\/p\u003e\u003cp\u003eIts ZN6 construction uses AISI 316 stainless steel, with AISI 316L stainless steel impellers and diffusers fitted with removable wear rings. The rotating shaft is Duplex stainless steel UNS S 31803, while the replaceable coupling uses Duplex stainless steel UNS S 32304. Suspended sand up to 100 g\/m³ is permitted, while the standard L6W motor limits operating water temperature to 35°C.\u003c\/p\u003e\u003cp\u003eThe ZN612\/8 achieves a maximum head of 90 metres, with hydraulic performance specified to EN ISO 9906 Grade 3B. Water is discharged through the Rp 2 1\/2” (65 mm) threaded connection. A standard 6-inch NEMA motor connection permits coupling with an L6W submersible motor, with maximum immersion depth of 350 metres when used with L6W motors.\u003c\/p\u003e\u003cp\u003eThe discharge head is manufactured in microcast ASTM CF-8M (AISI 316 cast) material and includes an integrated stainless steel non-return valve. Safety-hook holes are incorporated into the discharge head to assist with lowering and securing the pump end during deep-well installation.\u003c\/p\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003eThe eight-stage radial layout provides the hydraulic lift required for groundwater and irrigation duties.\u003c\/li\u003e\n\u003cli\u003eRemovable wear rings make the hydraulic clearances serviceable when maintenance is required.\u003c\/li\u003e\n\u003cli\u003eAISI 316L impellers and diffusers provide the specified stainless-steel hydraulic construction.\u003c\/li\u003e\n\u003cli\u003eThe Duplex UNS S 31803 shaft is designed for the rotating assembly.\u003c\/li\u003e\n\u003cli\u003eThe replaceable Duplex UNS S 32304 coupling provides the specified coupling material and arrangement.\u003c\/li\u003e\n\u003cli\u003eAISI 316L tie rods and cable guard extend the stainless-steel construction around the pump end.\u003c\/li\u003e\n\u003cli\u003eThe microcast discharge head combines structural support with an integrated stainless steel non-return valve.\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":51059136790775,"sku":"ZN612\/8","price":5487.57,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn612-8-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller.png?v=1787570542","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn612-8-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
