Its additional hydraulic stage provides greater lift than the eight-stage configuration while maintaining a maximum flow of 275 L\/Min.\u003c\/p\u003e\u003cp\u003eThe pump end uses the ZN6 AISI 316 stainless steel construction, with AISI 316L stainless steel impellers and diffusers incorporating removable wear rings. A Duplex stainless steel UNS S 31803 shaft forms the rotating assembly, while the replaceable coupling is Duplex stainless steel UNS S 32304. With the standard L6W motor, the operating water temperature is limited to 35°C and suspended sand up to 100 g\/m³ is permitted.\u003c\/p\u003e\u003cp\u003eMaximum head is 102 metres and hydraulic performance is specified to EN ISO 9906 Grade 3B. The pump end uses the standard Rp 2 1\/2” (65 mm) threaded delivery connection and a standard 6-inch NEMA motor connection for coupling with an L6W submersible motor. Maximum immersion depth reaches 350 metres with L6W motors.\u003c\/p\u003e\u003cp\u003eInstallation is supported by the microcast discharge head and lower support, with the integrated stainless steel non-return valve incorporated into the discharge arrangement. Holes in the discharge head provide for safety-hook attachment when the pump end is lowered into the borehole.\u003c\/p\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003eThe nine-stage radial arrangement adds hydraulic lift for deeper borehole transfer duties.\u003c\/li\u003e\n\u003cli\u003eRemovable wear rings provide a maintainable hydraulic clearance arrangement.\u003c\/li\u003e\n\u003cli\u003eAISI 316L stainless steel impellers and diffusers provide the specified corrosion-resistant hydraulic construction.\u003c\/li\u003e\n\u003cli\u003eThe Duplex UNS S 31803 shaft provides the specified material for the rotating components.\u003c\/li\u003e\n\u003cli\u003eThe replaceable Duplex UNS S 32304 coupling supports the specified motor coupling arrangement.\u003c\/li\u003e\n\u003cli\u003eAISI 316L tie rods, cable guard and strainer form part of the external pump-end construction.\u003c\/li\u003e\n\u003cli\u003eThe integrated stainless steel non-return valve is incorporated into the discharge head for backflow control.\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":51059136823543,"sku":"ZN612\/9","price":5792.49,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn612-9-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller.png?v=1787570544","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn612-9-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
