Product Overview
Pressure boosting and water distribution in civil and industrial systems are addressed by the Lowara ZN8125-03-3S. 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 22 kW with a current draw of 47.5 Amps at 415V three-phase, the pump delivers 73.9 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 pump casing encloses the hydraulic section with a semi-axial flow impeller. The assembly has a dry weight of 122.4 kg and operates in liquid temperatures up to 25°C. Sand handling capability reaches 100 g/m³. The motor is constructed from AISI 316 stainless steel.
Winding protection is ensured by Class F insulation, with an IP68-rated enclosure for submerged operation. The AISI 316 stainless steel motor features water-lubricated thrust bearings. NEMA flange mounting and coupling dimensions are specified for standard motor mounting.

How does this submersible pump resist harsh borehole minerals and suspended abrasive grit?
Underground mineral resistance is assured by AISI 316 stainless steel construction in the ZN8125-03-3S, which tolerates abrasive sand particulates up to 100 g/m³.
Which electrical power source and supply voltage are necessary for this borehole pump?
Operating the motor on the ZN8125-03-3S requires a 22 kW electrical feed on a 380–415 V, 50 Hz, three-phase power supply, with full-load current rated at 47.5 A.
Does this borehole pump have a built-in check valve and can it operate on an incline?
Backflow prevention is managed by an integrated spring-loaded check valve in the ZN8125 03 3S discharge head, and horizontal mounting is supported at a minimum recommended 3° incline with the motor at the lowest position.
Can this submersible unit push water up from deep underground aquifers?
Operating across challenging underground depths, the ZN8125_03_3S develops a maximum dynamic head rating of approximately 73.9 m to overcome tall vertical risers and pipe friction.
What diameter pipe fits the top delivery port and how much water volume does it discharge?
Fitted with a heavy-duty 125 mm (Rp 5") discharge connection, the ZN8125-03-3S produces a maximum delivery capacity of approximately 3000 L/Min for installations in standard 8-inch well casings.
