Product Overview
Pressure boosting and water distribution in civil and industrial systems are addressed by the Lowara ZN8125-02/2B-3R. 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 11 kW with a current draw of 26 Amps at 415V three-phase, the pump delivers 39.1 m of head at 30 m³/h with a maximum flow of 2600 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 pump casing encloses the hydraulic section with a semi-axial flow impeller configuration. The assembly has a dry weight of 90.2 kg and operates in liquid temperatures up to 25°C. Sand handling capability reaches 100 g/m³.
Protection for the motor windings is provided by Class F insulation, while the IP68 enclosure supports submerged operation. NEMA flange mounting and coupling dimensions are specified for standard motor mounting.

Is an integrated check valve present in the head and can this unit be positioned horizontally?
Reverse drainage is arrested in the ZN8125-02/2B-3R via an integrated spring-loaded check valve in the discharge head, with horizontal mounting supported at a minimum recommended 3° incline with the motor lowest.
What vertical lift height does this borehole pump deliver when operating underground?
For deep well pressure requirements, the ZN8125-02-2B-3R yields a maximum dynamic head of approximately 39.1 m, delivering consistent vertical water lift.
What pipe connection diameter is on the pump head and how many liters can it push?
Riser piping mates with the standard 125 mm (Rp 5") outlet port, allowing the ZN8125 02 2B 3R to produce a maximum flow of approximately 2600 L/Min when installed in standard 8-inch well casings.
Is this deep well pump built from corrosion-resistant materials to prevent degradation?
Resistance against aggressive underground minerals is achieved through AISI 316 stainless steel, with the ZN8125_02_2B_3R tolerating suspended abrasive particles up to 100 g/m³.
What power rating and voltage requirements apply to this submersible borehole motor?
Electrical connections for the ZN8125-02/2B-3R require a 11 kW three-phase motor on 380–415 V, 50 Hz, three-phase, pulling approximately 26 A.
