Product Overview
Water table level control and mining applications are primary duties for the Lowara ZN8125-04/2B-3S. The pump also serves water supply from deep wells, pressure boosting in civil and industrial systems, irrigation, supply of surge tanks and reservoirs, and firefighting and washing systems. The pump is suitable for borehole installation, with horizontal arrangements possible at a 3-degree minimum inclination.
Rated at 26 kW with a current draw of 56.5 Amps at 415V three-phase, the pump develops 88.3 m of head at 30 m³/h with a maximum flow of 2600 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 houses the hydraulic section with a semi-axial flow impeller configuration. The assembly weighs 140.6 kg and operates at liquid temperatures up to 25°C. Sand handling capacity is rated at 100 g/m³. The motor is constructed from AISI 316 stainless steel.
Motor protection is achieved through Class F winding insulation, complemented by an IP68-rated enclosure for submerged duty. The AISI 316 stainless steel motor incorporates water-lubricated thrust bearings. NEMA-compliant flange mounting and coupling dimensions meet standard motor connection requirements.

What voltage and kilowatt rating are required to run this submersible pumping system?
The electrical motor driving the ZN8125-04/2B-3S is rated at 26 kW and operates on 380–415 V, 50 Hz, three-phase, drawing a nominal 56.5 A.
Is a check valve included in the discharge head and can this unit be installed horizontally?
The discharge head of the ZN8125-04-2B-3S houses an integrated spring-loaded check valve to eliminate reverse flow, with horizontal orientation supported at a minimum recommended 3° incline with the motor lowest.
What total dynamic head is this borehole pumping system capable of overcoming?
Drawing water from deep well installations, the ZN8125 04 2B 3S attains a peak dynamic head rating of approximately 88.3 m, generating dependable vertical lift for storage and distribution.
What connection size is on the pump discharge head and what is its peak flow output?
Discharge piping attaches to the integrated 125 mm (Rp 5") threaded head, enabling the ZN8125_04_2B_3S to achieve a peak flow rate of approximately 2600 L/Min within standard 8-inch well casings.
What metallurgy is used in this borehole pump to prevent corrosion from groundwater?
Protection against aggressive groundwater chemistry is achieved through AISI 316 stainless steel, enabling the ZN8125-04/2B-3S to manage abrasive solids up to 100 g/m³ without premature wear.
