Its maximum head of 61 metres provides a higher-lift configuration while retaining the flow capability of the ZN6 range.\u003c\/p\u003e\u003cp\u003eThe pump end uses 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 is used for the rotating assembly, while the motor connection uses a replaceable Duplex stainless steel UNS S 32304 coupling. The construction permits suspended sand up to 100 g\/m³.\u003c\/p\u003e\u003cp\u003eA C4S motor allows operation with water temperatures up to 60°C. The hydraulic performance is specified to EN ISO 9906 Grade 3B, with water discharged through the Rp 2 1\/2” (65 mm) threaded connection. The standard 4-inch NEMA motor connection accommodates the C4S motor, with maximum immersion of 300 metres.\u003c\/p\u003e\u003cp\u003eThe discharge head and lower support are manufactured in microcast ASTM CF-8M (AISI 316 cast) material. The integrated stainless steel non-return valve provides backflow control, while safety-hook holes assist in lowering and securing the pump end.\u003c\/p\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003eFive radial stages provide the additional hydraulic lift required for groundwater lowering.\u003c\/li\u003e\n\u003cli\u003eRemovable wear rings make the hydraulic stages serviceable.\u003c\/li\u003e\n\u003cli\u003eAISI 316L impellers and diffusers provide corrosion-resistant hydraulic surfaces.\u003c\/li\u003e\n\u003cli\u003eThe Duplex UNS S 31803 shaft provides the specified rotating construction.\u003c\/li\u003e\n\u003cli\u003eThe replaceable Duplex UNS S 32304 coupling forms part of the motor connection.\u003c\/li\u003e\n\u003cli\u003eAISI 316L tie rods and cable guard support the external pump-end arrangement.\u003c\/li\u003e\n\u003cli\u003eThe microcast discharge assembly incorporates the stainless steel 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":51059137282295,"sku":"4ZN616\/5","price":5147.01,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn616-5-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller.png?v=1787570571","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn616-5-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
