Product Overview
Mining applications and water table level control are handled by the Lowara Z8125-03/3A-3S. 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 18.5 kW with a current draw of 42 Amps at 415V three-phase, the pump develops 65.6 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 304 stainless steel pump casing houses the hydraulic section with a semi-axial flow impeller configuration. The assembly weighs 119.4 kg and operates at liquid temperatures up to 25°C. Sand handling capacity is rated at 100 g/m³. The motor is constructed from AISI 316 stainless steel.
Thermal protection for the motor is provided by Class F insulation, with an IP68-rated enclosure enabling submerged operation. The AISI 316 stainless steel motor incorporates water-lubricated thrust bearings. NEMA-compliant flange mounting and coupling dimensions meet standard motor connection requirements.
