The Lowara 4ZN616\/3-3 submersible pump features a 6-inch AISI 316 stainless steel wet end with a 4-inch motor connection, providing corrosion resistance for demanding borehole applications. Its microcast stainless steel construction ensures durability for continuous operation.\u003c\/p\u003e\u003cp\u003eWhy does the material matter? AISI 316 stainless steel resists corrosion from aggressive groundwater, extending the pump's service life. The stainless steel radial flow impeller with removable wear ring handles suspended sand up to 100 grams per cubic metre, while the integrated suction strainer protects internal components. The replaceable coupling simplifies maintenance without pump removal.\u003c\/p\u003e\u003cp\u003eDriven by a 2.2 kW three-phase motor at 415V, the pump draws 5.6 Amps and delivers 367 L\/Min maximum flow. Shut-off head reaches 36.6 metres, with the 65 mm discharge port connecting to standard pipework. Performance complies with EN ISO 9906 Grade 3B tolerances.\u003c\/p\u003e\u003cp\u003eClass F insulation with IP68 rating supports immersion up to 300 metres. The Duplex stainless steel shaft, AISI 316L tie rods, and NEMA-compatible coupling ensure long-term reliability. The unit meets ErP ecodesign requirements for energy efficiency.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e4Z = 6\" wet end with 4\" Lowara 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 utilizes Duplex stainless steel UNS S 31803 composition\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 immersion depth of 300 metres with C4S motor\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":50996248838391,"sku":"4ZN616\/3-3","price":3787.45,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn616-3-3-stainless-steel-2-2kw-deep-well-submersible-pump-with-radial-flow-impeller.png?v=1785838689","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn616-3-3-stainless-steel-2-2kw-deep-well-submersible-pump-with-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
