Its stage configuration provides increased hydraulic lift for applications where a lower-stage pump end may not provide sufficient head.\u003c\/p\u003e\u003cp\u003eThe ZN6 pump end is manufactured in AISI 316 stainless steel, with AISI 316L stainless steel impellers and diffusers and removable wear rings. The rotating shaft uses Duplex stainless steel UNS S 31803, while the replaceable coupling is Duplex stainless steel UNS S 32304. When matched with a C4S motor, the installation is limited to 60°C operating water temperature and permits suspended sand up to 100 g\/m³.\u003c\/p\u003e\u003cp\u003eA maximum flow of 275 L\/Min and maximum head of 136 metres are specified for the 4ZN612\/12, with hydraulic performance assessed to EN ISO 9906 Grade 3B. The standard Rp 2 1\/2” (65 mm) threaded connection provides the delivery outlet, while the standard 4-inch NEMA motor connection allows coupling with a C4S submersible motor. Maximum immersion depth is 300 metres with C4S motors.\u003c\/p\u003e\u003cp\u003eThe discharge arrangement uses a microcast ASTM CF-8M (AISI 316 cast) discharge head and lower support, incorporating the stainless steel integrated non-return valve. Safety-hook holes are also provided to assist with controlled lowering and securing during borehole installation.\u003c\/p\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003eThe twelve radial stages provide the hydraulic lift required for higher-head groundwater and pressure applications.\u003c\/li\u003e\n\u003cli\u003eRemovable impeller wear rings make the hydraulic clearances serviceable during maintenance.\u003c\/li\u003e\n\u003cli\u003eAISI 316L impellers and diffusers provide the specified material construction for the radial stages.\u003c\/li\u003e\n\u003cli\u003eThe Duplex UNS S 31803 shaft is used for the rotating assembly.\u003c\/li\u003e\n\u003cli\u003eThe replaceable Duplex UNS S 32304 coupling supports the specified motor connection arrangement.\u003c\/li\u003e\n\u003cli\u003eAISI 316L tie rods and cable guard maintain the stainless-steel construction around the pump end.\u003c\/li\u003e\n\u003cli\u003eThe microcast ASTM CF-8M discharge assembly combines the lower support with the integrated 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":51059136725239,"sku":"4ZN612\/12","price":7060.68,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn612-12-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller.png?v=1787570538","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn612-12-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
