Its higher stage count provides the additional head required for deeper groundwater applications while maintaining a maximum flow of 275 L\/Min.\u003c\/p\u003e\u003cp\u003eThe pump-end construction uses AISI 316 stainless steel, with AISI 316L stainless steel impellers and diffusers incorporating removable wear rings. The rotating shaft is Duplex stainless steel UNS S 31803 and the replaceable coupling is Duplex stainless steel UNS S 32304. With a C4S motor, the installation operates within the motor-compatible temperature range up to 60°C and permits suspended sand up to 100 g\/m³.\u003c\/p\u003e\u003cp\u003eThe 4ZN612\/11 reaches a maximum head of 124 metres, with hydraulic performance specified to EN ISO 9906 Grade 3B. Its discharge connection is the standard Rp 2 1\/2” (65 mm) threaded port, while the standard 4-inch NEMA motor connection permits coupling with a C4S submersible motor. Maximum immersion depth is 300 metres when paired with C4S motors.\u003c\/p\u003e\u003cp\u003eAt the discharge end, the microcast ASTM CF-8M (AISI 316 cast) head and lower support incorporate the integrated stainless steel non-return valve. Pre-drilled holes provide a defined attachment point for safety hooks, supporting the lowering and securing of the pump end during borehole installation.\u003c\/p\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003eThe eleven-stage radial hydraulic arrangement provides substantially greater lift than the lower-stage versions.\u003c\/li\u003e\n\u003cli\u003eRemovable wear rings provide a serviceable arrangement for maintaining the hydraulic clearances.\u003c\/li\u003e\n\u003cli\u003eAISI 316L impellers and diffusers provide the specified stainless-steel construction for the hydraulic stages.\u003c\/li\u003e\n\u003cli\u003eThe Duplex UNS S 31803 shaft provides the specified material for the rotating assembly.\u003c\/li\u003e\n\u003cli\u003eThe Duplex UNS S 32304 coupling is replaceable and forms part of the motor coupling arrangement.\u003c\/li\u003e\n\u003cli\u003eAISI 316L tie rods, cable guard and strainer extend the corrosion-resistant construction through the assembly.\u003c\/li\u003e\n\u003cli\u003eThe integrated stainless steel non-return valve is incorporated into the microcast discharge assembly.\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":51059136692471,"sku":"4ZN612\/11","price":6738.93,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn612-11-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller.png?v=1787570537","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn612-11-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
