Product Overview
Pressure boosting and water distribution in civil and industrial systems are addressed by the Lowara Z8125-05-3. The pump supports water supply from deep wells, 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 3-degree inclination.
Rated at 37 kW with a current draw of 80 Amps at 415V three-phase, the pump delivers 123.2 m of head at 30 m³/h with a maximum flow of 3000 L/Min. The 125 mm discharge outlet incorporates a non-return valve. Hydraulic performance is presented according to ISO 9906:2012 Grade 3B standards.
The AISI 304 stainless steel pump casing encloses the hydraulic section with a semi-axial flow impeller. The assembly has a dry weight of 168.9 kg and operates in liquid temperatures up to 25°C. Sand handling capability reaches 100 g/m³. The unit is identified as 304S/S PUMP & STD MOTOR.
Motor protection is achieved through Class F winding insulation, complemented by an IP68-rated enclosure for submerged duty. The standard motor incorporates water-lubricated thrust bearings. NEMA-compliant flange mounting and coupling dimensions meet standard motor connection requirements.
