Product Overview
For groundwater lowering at substantial depth, the ZN616/26 provides a twenty-six-stage radial flow pump end with a maximum head of 319 metres. The six-inch configuration retains a maximum flow of 367 L/Min for high-capacity borehole applications.
The ZN6 wet end is manufactured from AISI 316 stainless steel, with AISI 316L stainless steel impellers and diffusers fitted with removable wear rings. The rotating shaft uses Duplex stainless steel UNS S 31803 and the replaceable coupling uses Duplex stainless steel UNS S 32304. Suspended sand up to 100 g/m³ is permitted.
The standard L6W motor configuration limits operating water temperature to 35°C. Hydraulic performance is specified to EN ISO 9906 Grade 3B. Discharge is through the Rp 2 1/2– (65 mm) threaded connection, with a standard 6-inch NEMA motor connection and maximum immersion depth of 350 metres.
A microcast ASTM CF-8M (AISI 316 cast) discharge head and lower support incorporate the integrated stainless steel non-return valve. Safety-hook holes provide attachment points for installation and controlled lowering.
FEATURES
- Twenty-six radial stages provide the hydraulic lift required for deep groundwater lowering.
- Removable wear rings make the hydraulic clearances serviceable.
- AISI 316L impellers and diffusers form the specified stainless-steel hydraulic stages.
- The Duplex UNS S 31803 shaft provides the rotating assembly.
- The replaceable Duplex UNS S 32304 coupling provides the specified motor connection.
- AISI 316L tie rods and cable guard extend the stainless-steel construction.
- The microcast discharge head incorporates the lower support and stainless steel non-return valve.
* Submersible motor sold separately - requires coupling and assembly

Can this pumping unit lift borehole water upwards through tall vertical risers?
High-elevation water transfer is achieved by the ZN616/26, which delivers a maximum dynamic head of approximately 319.1 m from deep well shafts.
What is the top discharge connection size and what maximum flow rate can be expected?
Coupling to surface delivery pipes requires the top Rp 2 1/2" (65 mm) threaded outlet, where the ZN616-26 delivers up to a peak flow of approximately 367 L/Min inside standard 6-inch borehole installations.
What construction grade provides corrosion resistance against harsh groundwater chemistry?
Protection against electrochemical corrosion is ensured by the 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 construction of the ZN 616 26, which accommodates sand levels up to 100 g/m³.
What are the electrical requirements and voltage parameters for operating this pump?
Connecting the ZN_616_26 to power involves a 6-inch NEMA L6W motor rated at 18.5 kW operating across 380–415 V, 50 Hz, three-phase with 38.5 A current, with operating limits up to 35°C and immersion to 350 meters.
Does this borehole pump feature a built-in non-return valve and permit horizontal setup?
Reverse fluid flow is arrested by an integrated stainless steel non-return valve in the ZN616/26 discharge head, while horizontal orientation is supported at a minimum recommended 3° incline with the motor in the lowest position.
