Product Overview
Firefighting and washing systems and irrigation are served by the Lowara ZN8125-04/2A-3R. The pump also handles water supply from deep wells, pressure boosting in civil and industrial systems, supply of surge tanks and reservoirs, 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 30 kW with a current draw of 64.5 Amps at 415V three-phase, the pump delivers 93.1 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. The assembly has a dry weight of 143.6 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.

What is the maximum vertical elevation pressure delivered by this deep well pump?
Lifting water across steep vertical profiles, the ZN8125-04/2A-3R develops a maximum dynamic head of approximately 93.1 m, maintaining pressure through long delivery lines.
What connection dimensions exist on the discharge outlet and how much flow is discharged?
Fluid discharge is directed through the 125 mm (Rp 5") outlet port, where the ZN8125-04-2A-3R attains a maximum flow capacity of approximately 2600 L/Min inside standard 8-inch well casings.
Is this submersible borehole pump built to resist corrosion from mineralized water?
Long-lasting subterranean operation is supported by AISI 316 stainless steel metallurgy in the ZN8125 04 2A 3R, which tolerates sand content up to 100 g/m³.
What power supply voltage and motor kilowatt rating are required for this borehole pump?
Operating requirements for the ZN8125_04_2A_3R specify a 30 kW motor running on 380–415 V, 50 Hz, three-phase, with full-load amperage rated at 64.5 A.
Is an internal check valve built into the discharge and does it support horizontal positioning?
Reverse drainage is prevented by an integrated spring-loaded check valve in the ZN8125-04/2A-3R discharge head, while horizontal mounting is supported at a minimum recommended 3° incline with the motor lowest.
