Product Overview
Pressure boosting and water distribution in civil and industrial systems are addressed by the Lowara ZN8125-03-3R. 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.
Winding protection is ensured by Class F insulation, with an IP68-rated enclosure for submerged operation. NEMA flange mounting and coupling dimensions are specified for standard motor mounting.

Is an integrated non-return valve built into the head and can this pump mount on an angle?
Safeguarding discharge piping against drainage, the ZN8125-03-3R features an integrated spring-loaded check valve in the head and allows horizontal installation at a minimum recommended 3° incline with the motor lowest.
Can this pumping unit lift borehole water upwards through tall vertical risers?
Subterranean borehole lifting duties are served by the ZN8125 03 3R, which reaches a maximum dynamic head of approximately 73.9 m under standard test ratings.
What size riser pipe connects to the delivery port and how much water flow does it produce?
Discharge connections are made using the 125 mm (Rp 5") threaded port, through which the ZN8125_03_3R supplies up to approximately 3000 L/Min inside standard 8-inch well casings.
What grade of stainless steel alloy protects this pump from corrosive well environments?
Groundwater minerals and abrasive particulates are resisted by AISI 316 stainless steel in the ZN8125-03-3R, which supports a sand capacity of up to 100 g/m³.
