Product Overview
Water supply from deep wells and pressure boosting in civil and industrial systems are the primary duties for the Lowara ZN8125-01-3R. 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 at a minimum recommended inclination of 3 degrees.
Rated at 7.5 kW with a current draw of 18.3 Amps at 415V three-phase, the pump develops 24.6 m of head at 30 m³/h with a maximum flow of 3000 L/Min. The 125 mm discharge outlet includes an integrated non-return valve. Performance is presented according to ISO 9906:2012 Grade 3B tolerances.
The AISI 316 stainless steel pump casing encloses the hydraulic section with a semi-axial flow impeller. The assembly weighs 72.9 kg and operates in liquid temperatures up to 25°C. Sand handling capability reaches 100 g/m³.
Submerged borehole duty is supported to 350 m, with Class F insulation and IP68-rated enclosure providing motor protection. NEMA-compliant flange mounting and coupling dimensions meet standard motor connection requirements.

Which electrical supply and motor rating are necessary to power this borehole unit?
Running the motor for the ZN8125-01-3R demands a 7.5 kW power source operating across 380–415 V, 50 Hz, three-phase, with nominal current at 18.3 A.
Does this submersible pump include a discharge check valve and support horizontal layout?
Integrated into the delivery casing, an integrated spring-loaded check valve protects the ZN8125-01-3R from backflow, and horizontal operation is permitted at a minimum recommended 3° incline with the motor at the lowest position.
Can this deep well pump manage substantial vertical lifting depths from deep water reservoirs?
Delivering strong vertical pressure, the ZN8125 01 3R provides a peak dynamic head rating of approximately 24.6 m to push water up from deep subterranean wells.
Which plumbing thread connects to the discharge port and what maximum water flow is delivered?
Plumbing connections attach to the 125 mm (Rp 5") discharge head, enabling the ZN8125_01_3R to supply a peak flow rate of approximately 3000 L/Min inside standard 8-inch well casings.
What corrosion defense and wear resistance does this submersible pumping unit provide?
Engineered to withstand corrosive groundwater environments, the ZN8125-01-3R utilizes AISI 316 stainless steel and provides abrasion-resistant durability up to 100 g/m³.
