Product Overview
Municipal water supply and high-rise pressure boosting rely on the Lowara ZN875-04-3R, which features an AISI 316 stainless steel pump with a Duplex stainless steel motor. Agricultural irrigation and industrial water distribution also benefit from its corrosion-resistant materials. The Duplex motor provides corrosion-resistant construction for aggressive environments.
A 22 kW motor drawing 47.3 Amps at 415V three-phase develops 105.8 m of head and a maximum flow of 1833.3 L/Min. The 125 mm discharge port includes an integrated non-return valve. Hydraulic performance is presented according to ISO 9906:2012 Grade 3B standards.
The AISI 316 stainless steel pump casing contains a semi-axial flow impeller trimmed to 143 mm. The assembly weighs 131.6 kg and processes sand up to 100 g/m³ at 25°C. The Duplex stainless steel motor offers corrosion-resistant construction for challenging water conditions.
Class F insulation and IP68 protection enable immersion to 350 m depth. The L6WR220 motor incorporates water-lubricated thrust bearings. NEMA flange mounting and dual cable covers maintain the 198 mm diameter for 8-inch well compatibility.

What elevation height can this multi-stage submersible pump achieve?
With a maximum dynamic head rating of 105 m, the ZN875-04-3R efficiently lifts groundwater from deep borehole shafts and elevates it to surface storage.
How much water flow can this 8-inch bore pump deliver continuously?
The ZN875-04-3R achieves a peak water delivery rate of 1833.3 L/Min through its integrated 125 mm top outlet connection.
Is this bore pump constructed with high-grade stainless alloys?
The ZN875 04 3R is built using cast AISI 316 stainless steel pump casing with a duplex stainless steel motor, ensuring long-term structural integrity in demanding borehole environments.
What motor kilowatt rating powers this multi-stage pump assembly?
The ZN875_04_3R is driven by a 22 kW / 415v motor requiring 415V three-phase electrical power for high-demand pumping.
Does the discharge head feature a spring-assisted non-return valve?
Yes. The ZN875-04-3R includes an integrated non-return check valve with a stainless steel spring in the discharge port to limit backflow during shutdown.
