Its large number of hydraulic stages is intended for demanding deep-well applications and provides a maximum flow of 275 L\/Min.\u003c\/p\u003e\u003cp\u003eThe ZN6 construction uses AISI 316 stainless steel, with AISI 316L stainless steel impellers and diffusers incorporating 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 the standard 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\/28 reaches a maximum head of 318 metres, with hydraulic performance specified to EN ISO 9906 Grade 3B. Water is delivered through the standard Rp 2 1\/2” (65 mm) threaded connection. A standard 6-inch NEMA motor connection permits coupling with an L6W submersible motor, and maximum immersion depth is 350 metres with L6W motors.\u003c\/p\u003e\u003cp\u003eAt the discharge end, the microcast ASTM CF-8M (AISI 316 cast) head and lower support incorporate the integrated stainless steel non-return valve. Safety-hook holes are provided for attachment during deep-well installation, supporting the controlled lowering and securing of the pump end.\u003c\/p\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003eThe twenty-eight-stage radial layout provides the high hydraulic lift required for deep-well groundwater extraction.\u003c\/li\u003e\n\u003cli\u003eRemovable wear rings allow the hydraulic clearances to be serviced when required.\u003c\/li\u003e\n\u003cli\u003eAISI 316L radial 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\u003eThe replaceable Duplex UNS S 32304 coupling forms part of the motor coupling arrangement.\u003c\/li\u003e\n\u003cli\u003eAISI 316L tie rods and cable guard maintain the specified stainless-steel external construction.\u003c\/li\u003e\n\u003cli\u003eThe microcast discharge head integrates the lower support and 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":51059137151223,"sku":"ZN612\/28","price":12156.21,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn612-28-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller.png?v=1787570563","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn612-28-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
