Product Overview
For deep aquifer extraction, agricultural irrigation and mine dewatering systems requiring substantial hydraulic lift, the ZN612/19 provides a nineteen-stage radial flow pump end for six-inch installations. Its nineteen-stage arrangement is intended for high-lift groundwater applications and provides a maximum flow of 275 L/Min.
The ZN6 pump end uses AISI 316 stainless steel construction, with AISI 316L stainless steel impellers and diffusers fitted with removable wear rings. A Duplex stainless steel UNS S 31803 shaft forms the rotating assembly, while the replaceable coupling uses Duplex stainless steel UNS S 32304. The standard L6W motor configuration permits suspended sand up to 100 g/m³ and limits operating water temperature to 35°C.
Maximum head reaches 215 metres, with hydraulic performance specified to EN ISO 9906 Grade 3B. The standard Rp 2 1/2– (65 mm) threaded connection provides the delivery outlet, and the standard 6-inch NEMA motor connection allows coupling with an L6W submersible motor. Maximum immersion depth is 350 metres with L6W motors.
The discharge assembly uses a microcast ASTM CF-8M (AISI 316 cast) discharge head and lower support with an integrated stainless steel non-return valve. Safety-hook holes are included for attachment during deep-well installation, providing the specified means of securing the pump end during lowering.

How much maintenance does the Lowara ZN612/19 need?
Virtually none. The sealed bearings and shaft seals are lubricated for life, giving you years of trouble-free daily pumping.
How deep can the Lowara ZN612/19 push water from underground?
With a maximum head of 215 m, it easily lifts water from deep bore shafts and pushes it across long pipe runs without losing pressure.
Can the Lowara ZN612 19 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 ZN612-19 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.
