Product Overview
Water supply from deep wells and pressure boosting in civil and industrial systems are primary applications for the Lowara ZN8125-04-3R. 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 30 kW with a current draw of 64.5 Amps at 415V three-phase, the pump delivers 98.6 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 143.6 kg and operates in liquid temperatures up to 25°C. Sand handling capability reaches 100 g/m³.
Thermal protection for the motor is provided by Class F insulation, with an IP68-rated enclosure enabling submerged operation. NEMA-compliant flange mounting and coupling dimensions meet standard motor connection requirements.

What delivery port thread size is built into the pump and what peak volume is pumped?
Installation to delivery pipes is completed via the 125 mm (Rp 5") discharge head, with the ZN8125-04-3R reaching a peak flow rate of approximately 3000 L/Min within standard 8-inch well casings.
What materials prevent corrosion and abrasive damage inside this borehole pump?
To withstand aggressive water tables, the ZN8125-04-3R is manufactured from AISI 316 stainless steel, ensuring robust resistance against wear and sand up to 100 g/m³.
What are the specific motor power and electrical voltage demands for this unit?
Powering the heavy-duty drive on the ZN8125 04 3R requires a 30 kW motor supported by 380–415 V, 50 Hz, three-phase at 64.5 A.
Does this borehole pump include a non-return valve and can it be arranged horizontally?
Featuring an integrated spring-loaded check valve in the discharge head, the ZN8125_04_3R stops backflow and supports horizontal installation at a minimum recommended 3° incline with the motor at the lowest position.
How effectively does this borehole pump push water up through long vertical pipe columns?
Overcoming deep well hydraulic resistance, the ZN8125-04-3R delivers a peak dynamic head of approximately 98.6 m for reliable water distribution.
