Its six-stage configuration increases the available head while retaining the 275 L\/Min maximum flow rating of the range.\u003c\/p\u003e\u003cp\u003eThe pump end follows the ZN6 AISI 316 stainless steel construction, with AISI 316L stainless steel impellers and diffusers incorporating removable wear rings. The shaft is Duplex stainless steel UNS S 31803, while the replaceable coupling uses Duplex stainless steel UNS S 32304. The specified construction permits suspended sand up to 100 g\/m³ and, when matched with a C4S motor, supports operation up to 60°C.\u003c\/p\u003e\u003cp\u003eMaximum head is 68 metres, with hydraulic performance specified according to EN ISO 9906 Grade 3B. Water is delivered through the Rp 2 1\/2” (65 mm) threaded connection, while the standard 4-inch NEMA motor connection allows the pump end to be coupled with a C4S submersible motor. Maximum immersion depth is 300 metres when used with the C4S motor.\u003c\/p\u003e\u003cp\u003eThe discharge assembly combines a microcast ASTM CF-8M (AISI 316 cast) discharge head and lower support with an integrated stainless steel non-return valve. Holes provided for safety-hook attachment assist with lowering and securing the pump end during deep borehole installation.\u003c\/p\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003eThe six radial stages provide greater hydraulic lift than the lower-stage configuration while retaining the specified flow rating.\u003c\/li\u003e\n\u003cli\u003eAISI 316L impellers and diffusers provide the corrosion-resistant hydraulic surfaces specified for the ZN6 construction.\u003c\/li\u003e\n\u003cli\u003eRemovable wear rings allow the hydraulic clearances to be serviced as required.\u003c\/li\u003e\n\u003cli\u003eThe Duplex UNS S 31803 shaft provides the specified material strength for the rotating assembly.\u003c\/li\u003e\n\u003cli\u003eAISI 316L tie rods, cable guard and strainer form part of the stainless-steel pump-end arrangement.\u003c\/li\u003e\n\u003cli\u003eThe integrated stainless steel non-return valve is positioned within the discharge assembly for backflow control.\u003c\/li\u003e\n\u003cli\u003eThe microcast discharge head provides the structural connection and safety-hook provisions required for installation.\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":51059136594167,"sku":"4ZN612\/6","price":5158.89,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn612-6-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller.png?v=1787570533","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn612-6-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
