Continuous submersion in abrasive borehole conditions demands equipment that minimizes maintenance interruptions, and this 2.2 kW unit delivers through its all-stainless construction and replaceable coupling. The integrated non-return valve prevents backflow, while the 142 mm overall diameter fits standard casings.\u003c\/p\u003e\n\u003cp\u003ePowered by a 415V three-phase motor drawing 6.1 Amps, maximum flow reaches 275 L\/Min with shut-off head of 45.4 metres. Performance curves comply with EN ISO 9906 Grade 3B, ensuring predictable operation. The 65 mm discharge port connects to standard pipework, and the suction strainer limits sand ingress to 100 g\/m3.\u003c\/p\u003e\n\u003cp\u003eAISI 316 stainless steel throughout the wet end resists corrosion from aggressive groundwater and abrasive particles. The radial flow impeller includes a removable wear ring, allowing component replacement without full pump disassembly. The replaceable coupling simplifies routine servicing, reducing downtime in critical applications.\u003c\/p\u003e\n\u003cp\u003eWeighing 27 kg, the pump features microcast stainless steel head and motor support castings. Safety hook holes on the discharge head facilitate secure lowering during installation. Liquid temperature tolerance extends to 60°C, and the unit accepts both C4S and L6W motor configurations.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eShaft manufactured from Duplex stainless steel UNS S 31803 for high strength\u003c\/li\u003e\n\u003cli\u003eExternal tie rods constructed from AISI 316L stainless steel for corrosion protection\u003c\/li\u003e\n\u003cli\u003eShaft sleeves provide wear protection for internal rotating components\u003c\/li\u003e\n\u003cli\u003eLower motor support uses ASTM CF-8M cast stainless steel construction\u003c\/li\u003e\n\u003cli\u003eElastomers utilize EPDM materials for reliable fluid sealing\u003c\/li\u003e\n\u003cli\u003eThrust bearings incorporate PTFE and Graphite for friction management\u003c\/li\u003e\n\u003cli\u003eErP 2009\/125\/EC compliant with MEI ≥ 0.40 at 2900 rpm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e* Motor and pump supplied separately - requires assembly\u003c\/p\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":50994308546807,"sku":"4ZN612\/4-3","price":3787.45,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn612-4-3-stainless-steel-2-2kw-three-phase-submersible-pump-with-radial-flow-impeller.png?v=1785755075","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn612-4-3-stainless-steel-2-2kw-three-phase-submersible-pump-with-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
