The Lowara ZN631\/4-3 combines a 6-inch wet end with 6-inch motor, achieving 667 L\/Min for continuous water delivery. The microcast stainless steel housing provides long-term structural integrity.\u003c\/p\u003e\u003cp\u003eSuction strainer design limits sand passage to 100 grams per cubic metre, preserving internal clearances. The non-return valve secures the water column against reverse flow. AISI 316 stainless steel throughout the wetted components offers corrosion resistance. The impeller incorporates a removable wear ring for maintenance access.\u003c\/p\u003e\u003cp\u003eDriven by 415V three-phase supply drawing 12.7 Amps, shut-off head reaches 57.9 metres.
