Product Overview
Water table level control and mining applications are primary duties for the Lowara ZN8125-04/2B-3R. The pump also serves water supply from deep wells, pressure boosting in civil and industrial systems, irrigation, supply of surge tanks and reservoirs, and firefighting and washing systems. The pump is suitable for borehole installation, with horizontal arrangements possible at a 3-degree minimum inclination.
Rated at 26 kW with a current draw of 56.5 Amps at 415V three-phase, the pump develops 88.3 m of head at 30 m³/h with a maximum flow of 2600 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 houses the hydraulic section with a semi-axial flow impeller configuration. The assembly weighs 140.6 kg and operates at liquid temperatures up to 25°C. Sand handling capacity is rated at 100 g/m³.
Motor protection is achieved through Class F winding insulation, complemented by an IP68-rated enclosure for submerged duty. NEMA-compliant flange mounting and coupling dimensions meet standard motor connection requirements.
