Product Overview
For agricultural irrigation systems operating from deeper boreholes, the ZN616/22 combines twenty-two radial stages with a maximum head of 270 metres. Its maximum flow of 367 L/Min provides the capacity needed for substantial irrigation water delivery.
The ZN6 pump end uses AISI 316 stainless steel, with AISI 316L stainless steel impellers and diffusers fitted with removable wear rings. The rotating shaft is Duplex stainless steel UNS S 31803 and the replaceable coupling is Duplex stainless steel UNS S 32304. Suspended sand up to 100 g/m³ is permitted.
The standard L6W motor configuration supports water temperatures up to 35°C. Hydraulic performance is specified to EN ISO 9906 Grade 3B. The Rp 2 1/2– (65 mm) threaded connection serves as the discharge outlet, while the standard 6-inch NEMA motor connection allows coupling with an L6W motor. Maximum immersion is 350 metres.
The microcast ASTM CF-8M (AISI 316 cast) discharge head and lower support contain an integrated stainless steel non-return valve. Safety-hook holes provide the required installation attachment points.
FEATURES
- Twenty-two radial stages provide the high lift required for agricultural irrigation.

Which electrical supply and motor rating are necessary to power this borehole unit?
Proper motor operation for the ZN616/22 demands a 6-inch NEMA L6W motor rated for 18.5 kW on a 380–415 V, 50 Hz, three-phase line at 38.5 A, rated for fluid temperatures up to 35°C and immersion to 350 meters.
Does this submersible pump include a discharge check valve and support horizontal layout?
Integrated into the delivery casing, an integrated stainless steel non-return valve protects the ZN616-22 from backflow, and horizontal operation is permitted at a minimum recommended 3° incline with the motor at the lowest position.
How much total vertical column pressure can this borehole pump generate from depth?
Delivering strong vertical pressure, the ZN 616 22 provides a peak dynamic head rating of approximately 270 m to push water up from deep subterranean wells.
Which plumbing thread connects to the discharge port and what maximum water flow is delivered?
Plumbing connections attach to the Rp 2 1/2" (65 mm) discharge head, enabling the ZN_616_22 to supply a peak flow rate of approximately 367 L/Min inside standard 6-inch borehole installations.
What corrosion defense and wear resistance does this submersible pumping unit provide?
Engineered to withstand corrosive groundwater environments, the ZN616/22 utilizes AISI 316 stainless steel pump end, AISI 316L stainless steel impellers and diffusers with removable wear rings, Duplex UNS S 31803 shaft, and Duplex UNS S 32304 coupling and provides abrasion-resistant durability up to 100 g/m³.
