The arrangement provides a maximum flow of 275 L\/Min.\u003c\/p\u003e\u003cp\u003eFollowing the ZN6 construction specification, the pump end uses AISI 316 stainless steel, with AISI 316L stainless steel impellers and diffusers and 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, with suspended sand permitted up to 100 g\/m³.\u003c\/p\u003e\u003cp\u003eThe ZN612\/11 achieves a maximum head of 124 metres and is specified to EN ISO 9906 Grade 3B for hydraulic performance. The Rp 2 1\/2” (65 mm) threaded connection provides the delivery outlet, while the standard 6-inch NEMA motor connection permits coupling with an L6W submersible motor. Maximum immersion depth is 350 metres with L6W motors.\u003c\/p\u003e\u003cp\u003eA microcast ASTM CF-8M (AISI 316 cast) discharge head and lower support complete the discharge assembly. The integrated stainless steel non-return valve is incorporated into the head, while safety-hook holes provide a practical attachment point for borehole lowering and installation.\u003c\/p\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003eThe eleven-stage radial arrangement provides additional lift for deep groundwater and high-pressure supply.\u003c\/li\u003e\n\u003cli\u003eRemovable wear rings allow the hydraulic clearances to be serviced as part of maintenance.\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 provides the specified material for the rotating assembly.\u003c\/li\u003e\n\u003cli\u003eA replaceable Duplex UNS S 32304 coupling forms part of the motor connection arrangement.\u003c\/li\u003e\n\u003cli\u003eAISI 316L tie rods and cable guard extend the stainless-steel construction through the assembly.\u003c\/li\u003e\n\u003cli\u003eThe ASTM CF-8M microcast discharge head incorporates the 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":51059136889079,"sku":"ZN612\/11","price":6443.91,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn612-11-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller.png?v=1787570548","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn612-11-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
