The increased number of stages provides the hydraulic lift required for deeper installations while maintaining a maximum flow of 275 L\/Min.\u003c\/p\u003e\u003cp\u003eIts ZN6 pump-end 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 and the replaceable coupling is Duplex stainless steel UNS S 32304. With an L6W motor, operating water temperature is limited to 35°C and suspended sand up to 100 g\/m³ is permitted.\u003c\/p\u003e\u003cp\u003eThe ZN612\/21 achieves a maximum head of 238 metres and has hydraulic performance specified to EN ISO 9906 Grade 3B. The standard Rp 2 1\/2” (65 mm) threaded delivery connection provides the outlet. A standard 6-inch NEMA motor connection allows coupling with an L6W submersible motor, with maximum immersion depth of 350 metres using L6W motors.\u003c\/p\u003e\u003cp\u003eThe microcast ASTM CF-8M (AISI 316 cast) discharge head and lower support incorporate an integrated stainless steel non-return valve. Safety-hook holes are provided in the discharge head to assist with lowering and securing the pump end during borehole installation.\u003c\/p\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003eThe twenty-one-stage radial arrangement supplies the high hydraulic lift required for deep-borehole applications.\u003c\/li\u003e\n\u003cli\u003eRemovable wear rings provide serviceable hydraulic clearances within the radial stages.\u003c\/li\u003e\n\u003cli\u003eAISI 316L impellers and diffusers provide the specified stainless-steel construction of the hydraulic stages.\u003c\/li\u003e\n\u003cli\u003eThe Duplex UNS S 31803 shaft is selected for the rotating assembly.\u003c\/li\u003e\n\u003cli\u003eThe replaceable Duplex UNS S 32304 coupling provides the specified coupling material.\u003c\/li\u003e\n\u003cli\u003eAISI 316L tie rods and cable guard form part of the stainless-steel external assembly.\u003c\/li\u003e\n\u003cli\u003eThe ASTM CF-8M microcast discharge head incorporates the non-return valve and lower support.\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":51059137052919,"sku":"ZN612\/21","price":9389.16,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn612-21-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller.png?v=1787570558","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn612-21-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
