Water supply from deep wells and pressure boosting in civil and industrial systems are the primary duties for the Lowara ZN8125-01-3S. The pump also serves irrigation, supply of surge tanks and reservoirs, firefighting and washing systems, water table level control, and mining applications. The pump is suitable for borehole installation, with horizontal arrangements possible at a minimum recommended inclination of 3 degrees.
Rated at 7.5 kW with a current draw of 18.3 Amps at 415V three-phase, the pump develops 24.6 m of head at 30 m³/h with a maximum flow of 3000 L/Min. The 125 mm discharge outlet includes an integrated non-return valve. Performance is presented according to ISO 9906:2012 Grade 3B tolerances.
The AISI 316 stainless steel pump casing encloses the hydraulic section with a semi-axial flow impeller. The assembly weighs 72.9 kg and operates in liquid temperatures up to 25°C. Sand handling capability reaches 100 g/m³. The motor is constructed from AISI 316 stainless steel.
Submerged borehole duty is supported to 350 m, with Class F insulation and IP68-rated enclosure providing motor protection. The AISI 316 stainless steel motor features water-lubricated thrust bearings. NEMA-compliant flange mounting and coupling dimensions meet standard motor connection requirements.
