Product Overview
Firefighting and washing systems and irrigation are served by the Lowara ZN8125-04/2A-3S. The pump also handles water supply from deep wells, pressure boosting in civil and industrial systems, supply of surge tanks and reservoirs, 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 30 kW with a current draw of 64.5 Amps at 415V three-phase, the pump delivers 93.1 m of head at 30 m³/h with a maximum flow of 2600 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 143.6 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.
Insulation class F protects the motor windings, while the IP68 enclosure rating supports full submersion. The AISI 316 stainless steel motor features water-lubricated thrust bearings. NEMA flange mounting and coupling dimensions are specified for standard motor mounting.

Does this submersible pump feature an integrated non-return valve for horizontal service?
System piping protection is ensured by an integrated spring-loaded check valve in the ZN8125-04/2A-3S, which also allows horizontal installation with a minimum recommended 3° incline and motor in the lowest position.
How high can this groundwater extraction pump raise water from deep down a well shaft?
Across vertical elevation duties, the ZN8125-04-2A-3S generates a maximum dynamic head capacity of approximately 93.1 m to elevate groundwater efficiently from deep subterranean strata.
Which pipe dimension mates with the discharge outlet and what maximum flow is achieved?
Delivery lines couple to the top 125 mm (Rp 5") outlet port, allowing the ZN8125 04 2A 3S to pump up to approximately 2600 L/Min while operating inside standard 8-inch well casings.
Is this pump manufactured from corrosion-resistant alloy to withstand underground elements?
Equipped with robust AISI 316 stainless steel hydraulic components, the ZN8125_04_2A_3S prevents surface deterioration while supporting a sand tolerance of up to 100 g/m³.
What electrical power specifications and phase supply does this borehole motor require?
Proper motor operation for the ZN8125-04/2A-3S necessitates a 30 kW capacity on a 380–415 V, 50 Hz, three-phase electrical system, with a current demand of 64.5 A.
