The Lowara 4ZN660\/2-3 processes 1300 L\/Min through its 6-inch wet end with 4-inch motor connection, handling large volumes for construction site dewatering and municipal water transfer projects. The radial flow impeller arrangement delivers efficient hydraulic performance across the operating range.\u003c\/p\u003e\u003cp\u003eCorrosion resistance comes from AISI 316 stainless steel throughout the wet end, protecting internal components from aggressive groundwater. The impeller includes a removable wear ring for maintenance access without complete disassembly. The suction strainer limits suspended sand to 100 grams per cubic metre, safeguarding internal clearances. The integrated non-return valve prevents reverse flow during motor shutdown, while safety hook holes facilitate installation and retrieval.\u003c\/p\u003e\u003cp\u003ePower comes from a 4 kW three-phase motor at 415V drawing 10.2 Amps. Maximum head reaches 21 metres at shut-off with flow capacity of 1300 L\/Min through the 80 mm discharge port. Hydraulic performance meets EN ISO 9906 Grade 3B tolerances for reliable operation across varying duty points.\u003c\/p\u003e\u003cp\u003eClass F insulation with IP68 rating supports immersion to 300 metres. The Duplex stainless steel shaft and AISI 316L tie rods provide mechanical durability. NEMA motor compatibility simplifies assembly, and the microcast stainless steel construction ensures long-term structural integrity in 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":51001341313271,"sku":"4ZN660\/2-3","price":4728.4,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn660-2-3-stainless-steel-4kw-deep-well-submersible-pump-with-radial-flow-impeller.png?v=1786007634","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn660-2-3-stainless-steel-4kw-deep-well-submersible-pump-with-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
