Product Overview
For high-pressure groundwater supply and deep-well extraction, the ZN612/11 provides an eleven-stage radial flow pump end designed to deliver increased hydraulic lift within a six-inch borehole installation. The arrangement provides a maximum flow of 275 L/Min.
Following the ZN6 construction specification, the pump end uses AISI 316 stainless steel, with AISI 316L stainless steel impellers and diffusers and removable wear rings. The rotating shaft is Duplex stainless steel UNS S 31803 and the replaceable coupling is Duplex stainless steel UNS S 32304. With an L6W motor, operating water temperature is limited to 35°C, with suspended sand permitted up to 100 g/m³.
The ZN612/11 achieves a maximum head of 124 metres and is specified to EN ISO 9906 Grade 3B for hydraulic performance. The Rp 2 1/2– (65 mm) threaded connection provides the delivery outlet, while the standard 6-inch NEMA motor connection permits coupling with an L6W submersible motor. Maximum immersion depth is 350 metres with L6W motors.
A microcast ASTM CF-8M (AISI 316 cast) discharge head and lower support complete the discharge assembly. The integrated stainless steel non-return valve is incorporated into the head, while safety-hook holes provide a practical attachment point for borehole lowering and installation.

How deep can the Lowara ZN612/11 push water from underground?
With a maximum head of 124 m, it easily lifts water from deep bore shafts and pushes it across long pipe runs without losing pressure.
Can the Lowara ZN612 11 handle dirty or gritty bore water?
The pump is designed for the documented sand/particle conditions; do not exceed the manufacturer's stated limits. The impellers are built from heavy-duty materials designed to resist abrasion and sediment wear.
Can I run the Lowara ZN612-11 off a farm generator or solar inverter?
Yes, as long as your generator matches its Continuous-Duty Electric Motor requirement. It's built for continuous duty on 415V three-phase or standard rural power setups.
Is the Lowara ZN612_11 safe to use in mineral-heavy or salty groundwater?
The pump uses stainless-steel wetted components; suitability for saline or aggressive water should be confirmed against the manufacturer's liquid-compatibility limits.
