Its staged hydraulic arrangement provides the lift required for extracting clean groundwater from deeper borehole systems while maintaining a maximum flow capability of 275 L\/Min.\u003c\/p\u003e\n\u003cp\u003eThe ZN6 pump end is built in AISI 316 stainless steel, with AISI 316L stainless steel used for the impellers and diffusers. Removable wear rings allow the hydraulic clearances to be serviced, while the rotating shaft is Duplex stainless steel UNS S 31803 and the replaceable coupling is Duplex stainless steel UNS S 32304. This construction is specified for clean water containing suspended sand up to 100 g\/m³.\u003c\/p\u003e\n\u003cp\u003eWith a C4S submersible motor, the assembly is suitable for operation up to 60°C and can reach a maximum head of 45 metres. Hydraulic performance is specified to EN ISO 9906 Grade 3B, with water discharged through the Rp 2 1\/2” (65 mm) connection. The pump end uses a standard 4-inch NEMA motor connection and permits maximum immersion of 300 metres when used with a C4S motor.\u003c\/p\u003e\n\u003cp\u003eInstallation is supported by a microcast ASTM CF-8M (AISI 316 cast) discharge head and lower support, with an integrated stainless steel non-return valve helping manage backflow within the discharge assembly. Safety-hook holes are incorporated into the discharge head for lowering and securing the pump end during borehole installation.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRemovable wear rings make the radial hydraulic stages serviceable during maintenance.\u003c\/li\u003e\n\u003cli\u003eDuplex UNS S 31803 shaft provides the rotating assembly with the specified mechanical strength.\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 32304 coupling provides a replaceable connection for the motor assembly.\u003c\/li\u003e\n\u003cli\u003eAISI 316L tie rods and cable guard support the pump-end construction and installation arrangement.\u003c\/li\u003e\n\u003cli\u003eThe integrated stainless steel non-return valve provides backflow control at the discharge.\u003c\/li\u003e\n\u003cli\u003eThe ASTM CF-8M microcast discharge head and lower support provide the specified structural arrangement for borehole installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e* Submersible motor sold separately - requires coupling and assembly\u003c\/p\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":51059136561399,"sku":"4ZN612\/4","price":4452.03,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn612-4-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller.png?v=1787570531","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn612-4-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
