The Lowara 4ZN660\/4-3 delivers 1300 L\/Min from its 6-inch wet end with 4-inch motor connection, providing reliable water transfer for city supply systems and large-scale farming operations. The radial flow hydraulic design ensures efficient energy transfer across the operating range.\u003c\/p\u003e\u003cp\u003eThe pump incorporates AISI 316 stainless steel throughout the wet end, protecting every component from corrosion and abrasive wear. The impeller includes a removable wear ring for simplified maintenance access. The integrated non-return valve prevents water column reversal during shutdown. The suction strainer limits suspended sand to 100 grams per cubic metre, preserving internal component integrity. Safety hook holes on the discharge head enable secure handling during installation.\u003c\/p\u003e\u003cp\u003eDriven by a 7.5 kW three-phase motor at 415V, the pump draws 18.1 Amps and achieves 42.8 metres of shut-off head. Flow capacity is 1300 L\/Min through the 80 mm discharge port. Performance complies with EN ISO 9906 Grade 3B tolerances for consistent hydraulic output.\u003c\/p\u003e\u003cp\u003eClass F insulation with IP68 rating supports immersion depths to 300 metres. The Duplex stainless steel shaft and AISI 316L tie rods provide mechanical durability. NEMA motor coupling simplifies assembly, and the microcast stainless steel head and motor support provide structural integrity for demanding applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e4Z = 6\" wet end with 4\" Lowara motor\u003c\/strong\u003e\u003c\/p\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003eDischarge head features pre-drilled holes for safety hook attachment\u003c\/li\u003e\n\u003cli\u003eShaft utilizes Duplex stainless steel UNS S 31803 metallurgy\u003c\/li\u003e\n\u003cli\u003eBracing tie rods are built from AISI 316L stainless steel\u003c\/li\u003e\n\u003cli\u003eMechanical coupling component is replaceable for standard servicing\u003c\/li\u003e\n\u003cli\u003eSuction strainer uses AISI 316L stainless steel mesh\u003c\/li\u003e\n\u003cli\u003eFlange assembly conforms to standard NEMA motor connections\u003c\/li\u003e\n\u003cli\u003eMaximum immersion depth of 300 metres with C4S motors\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":51001341378807,"sku":"4ZN660\/4-3","price":6136.65,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn660-4-3-stainless-steel-7-5kw-deep-well-submersible-pump-with-radial-flow-impeller.png?v=1786007638","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn660-4-3-stainless-steel-7-5kw-deep-well-submersible-pump-with-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
