The Lowara ZN616\/6-3 submersible pump delivers 73.6 metres of shut-off head, featuring a 6-inch AISI 316 stainless steel wet end with 6-inch motor connection. Its microcast stainless steel construction ensures durability for continuous borehole operation.\u003c\/p\u003e\u003cp\u003eThe engineering choices directly impact operational lifespan. AISI 316 stainless steel resists corrosion from aggressive groundwater, reducing the risk of premature failure. The stainless steel impeller with removable wear ring handles suspended sand up to 100 grams per cubic metre, while the integrated suction strainer protects internal clearances. The replaceable coupling simplifies maintenance without full pump extraction.\u003c\/p\u003e\u003cp\u003eDriven by a 5.5 kW three-phase motor at 415V, the pump draws 12.7 Amps and delivers 367 L\/Min maximum flow. Shut-off head reaches 73.6 metres, with the 65 mm discharge port connecting to standard pipework. Performance complies with EN ISO 9906 Grade 3B tolerances.\u003c\/p\u003e\u003cp\u003eImmersion depths up to 350 metres are supported by Class F insulation and IP68 enclosure rating. The Duplex stainless steel shaft, AISI 316L tie rods, and NEMA-compatible coupling ensure long-term reliability. The unit meets ErP ecodesign requirements.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eZ = 6\" wet end with 6\" Lowara L6C motor\u003c\/strong\u003e\u003c\/p\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eDelivery port incorporates integrated safety hook attachment points\u003c\/li\u003e\n\u003cli\u003eDrive shaft is manufactured from Duplex stainless steel UNS S 31803\u003c\/li\u003e\n\u003cli\u003eExternal tie rods are constructed from AISI 316L stainless steel\u003c\/li\u003e\n\u003cli\u003eSupplied with a replaceable coupling component for standard maintenance\u003c\/li\u003e\n\u003cli\u003eIntake strainer is fabricated from AISI 316L stainless steel\u003c\/li\u003e\n\u003cli\u003eLower motor support matches standard NEMA mounting dimensions\u003c\/li\u003e\n\u003cli\u003eMaximum permissible suspended sand concentration of 100 g\/m3\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e* Motor and pump supplied separately - requires assembly\u003c\/p\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":50996249067767,"sku":"ZN616\/6-3","price":6868.4,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn616-6-3-stainless-steel-5-5kw-deep-well-submersible-pump-with-radial-flow-impeller.png?v=1785838702","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn616-6-3-stainless-steel-5-5kw-deep-well-submersible-pump-with-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
