Product Overview
Water supply from deep wells and pressure boosting in civil and industrial systems are primary applications for the Lowara ZN8125-02-3R. 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.
Rated at 15 kW with a current draw of 34.2 Amps at 415V three-phase, the pump delivers 49.3 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 316 stainless steel casing encloses the hydraulic section with a semi-axial flow impeller. The assembly weighs 102.2 kg and operates in liquid temperatures up to 25°C. Sand handling capability reaches 100 g/m³.
Insulation class F protects the motor windings, while the IP68 enclosure rating supports full submersion. NEMA flange mounting and coupling dimensions are specified for standard motor mounting.

Which discharge fitting connects to the pump outlet and what peak flow volume is supplied?
Piping infrastructure attaches to the 125 mm (Rp 5") delivery port, with the ZN8125-02-3R maintaining a maximum flow capacity of approximately 3000 L/Min in standard 8-inch well casings.
How does the metallurgy of this submersible bore pump prevent corrosion and erosion?
Superior metallurgical durability is built into the ZN8125-02-3R using AISI 316 stainless steel, protecting hydraulic passages against erosion and sand up to 100 g/m³.
Which operating voltage and motor kilowatt rating are required for this submersible unit?
The motor for the ZN8125 02 3R requires a dedicated 15 kW connection on 380–415 V, 50 Hz, three-phase, with rated operating current of 34.2 A.
Is a check valve incorporated into the discharge port and is angled mounting possible?
To protect against backflow during shutdown, the ZN8125_02_3R includes an integrated spring-loaded check valve in the head and supports horizontal mounting at a minimum recommended 3° incline with the motor lowest.
How much total vertical column pressure can this borehole pump generate from depth?
To overcome substantial vertical depths, the ZN8125-02-3R achieves a maximum dynamic head performance of approximately 49.3 m, lifting water reliably to surface tanks.
