The Lowara 4ZN631\/4-3 processes 667 L\/Min through a 6-inch wet end with 4-inch motor connection. Its radial flow impeller arrangement delivers efficient hydraulic performance for water table management.\u003c\/p\u003e\u003cp\u003eShaft protection comes from Duplex stainless steel UNS S 31803, providing torsional strength during extended operation. The suction strainer limits suspended sand to 100 grams per cubic metre, safeguarding internal clearances. A removable wear ring on the impeller allows maintenance access. The integrated non-return valve prevents reverse flow during shutdown periods.\u003c\/p\u003e\u003cp\u003eA 415V three-phase motor drawing 12.6 Amps drives the pump to 57.9 metres shut-off head. Flow capacity is 667 L\/Min through the Rp 3 discharge port.
