Its staged hydraulic configuration provides a maximum flow of 275 L\/Min while increasing the available head for pressure supply duties.\u003c\/p\u003e\u003cp\u003eThe ZN6 pump-end construction uses AISI 316 stainless steel, with AISI 316L stainless steel impellers and diffusers incorporating removable wear rings. A Duplex stainless steel UNS S 31803 shaft drives the rotating assembly, and 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\u003eMaximum head is 136 metres, with hydraulic performance specified to EN ISO 9906 Grade 3B. The standard Rp 2 1\/2” (65 mm) threaded delivery connection serves as the outlet, while a standard 6-inch NEMA motor connection permits coupling with an L6W submersible motor. Maximum immersion depth is 350 metres when used with L6W motors.\u003c\/p\u003e\u003cp\u003eThe microcast ASTM CF-8M (AISI 316 cast) discharge head and lower support incorporate an integrated stainless steel non-return valve. Safety-hook holes in the discharge head provide for attachment during installation, allowing the pump end to be lowered and secured within the borehole.\u003c\/p\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003eThe twelve-stage radial configuration provides the additional hydraulic lift required for commercial groundwater supply.\u003c\/li\u003e\n\u003cli\u003eRemovable wear rings allow the hydraulic stages to retain a serviceable clearance arrangement.\u003c\/li\u003e\n\u003cli\u003eAISI 316L stainless steel impellers and diffusers form the specified radial hydraulic components.\u003c\/li\u003e\n\u003cli\u003eThe Duplex UNS S 31803 shaft provides the specified rotating-shaft construction.\u003c\/li\u003e\n\u003cli\u003eThe replaceable Duplex UNS S 32304 coupling forms part of the specified motor connection.\u003c\/li\u003e\n\u003cli\u003eAISI 316L tie rods and cable guard provide the specified stainless-steel external construction.\u003c\/li\u003e\n\u003cli\u003eThe integrated stainless steel non-return valve is incorporated into the microcast discharge head.\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":51059136921847,"sku":"ZN612\/12","price":6738.93,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn612-12-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller.png?v=1787570550","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn612-12-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
