Product Overview
Water supply from deep wells and pressure boosting in civil and industrial systems are the primary duties for the Lowara Z8125-01-3S. 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 304 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. The motor is constructed from AISI 316 stainless steel.
Submerged borehole duty is supported to 350 m, with Class F insulation and IP68-rated enclosure providing motor protection. The AISI 316 stainless steel motor features water-lubricated thrust bearings. NEMA-compliant flange mounting and coupling dimensions meet standard motor connection requirements.

Does this borehole pump require dedicated three-phase power?
Powered by a 7.5 kW / 415v motor operating on 415V three-phase power, the Z8125-01-3S ensures stable continuous operation.
How does the spring-loaded valve restrict backflow in well pipes?
Yes. The Z8125-01-3S includes an integrated spring-loaded check valve built into the discharge outlet to restrict liquid backflow when powered off.
What vertical head capability sets this submersible pump apart?
With a maximum dynamic head rating of 24 m, the Z8125 01 3S efficiently lifts groundwater from deep borehole shafts and elevates it to surface storage.
How rapidly can this borehole pump fill large storage reservoirs?
The Z8125_01_3S achieves a peak water delivery rate of 3000 L/Min through its integrated 125 mm top outlet connection.
Is the pump casing built to resist long-term underwater wear?
The Z8125-01-3S is built using AISI 304 stainless steel pump casing with an AISI 316 stainless steel motor, ensuring long-term structural integrity in demanding borehole environments.
