The Lowara ZN646\/25-3 delivers 255.1 metres of shut-off head from its 6-inch wet end, with a 37 kW motor configuration that provides substantial power for the most demanding applications. The multi-stage hydraulic assembly ensures efficient energy transfer across the operating range.\u003c\/p\u003e\u003cp\u003eCorrosion resistance is built into the design through AISI 316 stainless steel construction across every wetted surface, protecting against aggressive groundwater and abrasive wear. The impeller and diffuser arrangement incorporates a removable wear ring for simplified maintenance, while the integrated non-return valve prevents backflow during shutdown. The suction strainer limits suspended sand ingress to 100 grams per cubic metre, preserving internal clearances.\u003c\/p\u003e\u003cp\u003eDriven by a 37 kW three-phase motor at 415V, the pump draws 81.8 Amps and achieves 255.1 metres of shut-off head. Flow capacity reaches 1000 L\/Min through the 80 mm discharge port. Hydraulic performance complies with EN ISO 9906 Grade 3B tolerances for consistent output.\u003c\/p\u003e\u003cp\u003eClass F insulation with IP68 rating supports immersion depths to 350 metres. The Duplex stainless steel shaft provides mechanical strength, while AISI 316L tie rods offer structural integrity. Safety hook holes facilitate installation, and NEMA motor compatibility simplifies assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eZ = 6\" wet end with 6\" Lowara L6C motor\u003c\/strong\u003e\u003c\/p\u003e\u003cb\u003eFEATURES\u003c\/b\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\u003c\/ul\u003e\u003cp\u003e* Motor and pump supplied separately - requires assembly\u003c\/p\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":50998501310711,"sku":"ZN646\/25-3","price":23368.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn646-25-3-stainless-steel-37kw-deep-well-submersible-pump-with-radial-flow-impeller.png?v=1785921758","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn646-25-3-stainless-steel-37kw-deep-well-submersible-pump-with-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
