Product Overview
Mining applications and water table level control are handled by the Lowara ZN8125-05/3A-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 37 kW with a current draw of 80 Amps at 415V three-phase, the pump develops 114.9 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 168.9 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.
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.

What diameter plumbing connects to the delivery port and how much flow does it produce?
Surface piping connects to the 125 mm (Rp 5") discharge connection, where the ZN8125-05/3A-3S provides a peak flow capacity of approximately 2600 L/Min for standard 8-inch well casings.
How well does this submersible bore pump withstand abrasive sand and corrosive groundwater?
Long-term subterranean durability is provided by AISI 316 stainless steel housing, allowing the ZN8125-05-3A-3S to withstand mineral exposure and suspended sand up to 100 g/m³.
What kilowatt rating and voltage configuration are needed to power this borehole pump?
Connecting the ZN8125 05 3A 3S motor to power requires a 37 kW electrical configuration matching 380–415 V, 50 Hz, three-phase, drawing 80 A.
Does this borehole unit include a built-in non-return valve and can it mount horizontally?
Protection against backflow in the ZN8125_05_3A_3S is provided by an integrated spring-loaded check valve in the delivery head, with horizontal mounting supported at a minimum recommended 3° incline with the motor at the lowest position.
What is the peak vertical lift capacity for this borehole pumping unit?
Capable of overcoming substantial elevation resistance, the ZN8125-05/3A-3S reaches a maximum dynamic head of approximately 114.9 m to supply water from deep borehole reservoirs.
