Its extensive stage arrangement is intended for deep-well groundwater extraction and provides a maximum flow of 275 L\/Min.\u003c\/p\u003e\u003cp\u003eThe pump end uses AISI 316 stainless steel construction, with AISI 316L stainless steel impellers and diffusers incorporating removable wear rings. The rotating shaft is Duplex stainless steel UNS S 31803, while 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\/32 achieves a maximum head of 367 metres, with hydraulic performance specified to EN ISO 9906 Grade 3B. The standard 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\u003eThe discharge arrangement uses a microcast ASTM CF-8M (AISI 316 cast) discharge head and lower support with an integrated stainless steel non-return valve. Safety-hook holes are incorporated into the discharge head to support lowering and securing the pump end during deep-well installation.\u003c\/p\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003eThe thirty-two-stage radial configuration provides the substantial hydraulic lift required for very deep borehole installations.\u003c\/li\u003e\n\u003cli\u003eRemovable wear rings make the hydraulic clearances serviceable through maintenance.\u003c\/li\u003e\n\u003cli\u003eAISI 316L impellers and diffusers provide the specified stainless-steel construction across the radial stages.\u003c\/li\u003e\n\u003cli\u003eThe Duplex UNS S 31803 shaft provides the specified rotating assembly material.\u003c\/li\u003e\n\u003cli\u003eThe replaceable Duplex UNS S 32304 coupling provides the specified coupling construction.\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 ASTM CF-8M microcast discharge head incorporates the lower support and 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":51059137183991,"sku":"ZN612\/32","price":13386.78,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn612-32-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller.png?v=1787570565","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn612-32-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
