Product Overview
The ZN616/16 provides sixteen radial stages for six-inch borehole installations where high-lift wet-end configuration is required. It has a maximum flow of 367 L/Min and reaches a maximum head of 197 metres.
Its AISI 316 stainless steel construction is complemented by AISI 316L stainless steel impellers and diffusers with removable wear rings. The rotating shaft uses Duplex stainless steel UNS S 31803, while the replaceable coupling is Duplex stainless steel UNS S 32304. The specified wet-end construction permits suspended sand up to 100 g/m³.
When paired with an L6W motor, operating water temperature is limited to 35°C. Hydraulic performance is specified to EN ISO 9906 Grade 3B, with discharge through the Rp 2 1/2– (65 mm) threaded connection. The standard 6-inch NEMA motor connection is provided, with maximum immersion of 350 metres using an L6W motor.
The discharge assembly combines the microcast ASTM CF-8M (AISI 316 cast) head and lower support with an integrated stainless steel non-return valve. Safety-hook holes support controlled lowering and securing.
FEATURES
- Sixteen radial stages provide the high lift required for demanding applications.

Does this submersible pump feature an integrated non-return valve for horizontal service?
System piping protection is ensured by an integrated stainless steel non-return valve in the ZN616/16, which also allows horizontal installation with a minimum recommended 3° incline and motor in the lowest position.
What total dynamic head does this deep well bore pump deliver under full service?
Across vertical elevation duties, the ZN616-16 generates a maximum dynamic head capacity of approximately 197.5 m to elevate groundwater efficiently from deep subterranean strata.
Which pipe dimension mates with the discharge outlet and what maximum flow is achieved?
Delivery lines couple to the top Rp 2 1/2" (65 mm) outlet port, allowing the ZN 616 16 to pump up to approximately 367 L/Min while operating inside standard 6-inch borehole installations.
Is this pump manufactured from corrosion-resistant alloy to withstand underground elements?
Equipped with robust 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 hydraulic components, the ZN_616_16 prevents surface deterioration while supporting a sand tolerance of up to 100 g/m³.
What electrical power specifications and phase supply does this borehole motor require?
Electrical connection specifies a 6-inch NEMA L6W submersible motor rated for 11 kW on 380–415 V, 50 Hz, three-phase drawing 24.2 A for the ZN616/16, supporting water temperatures up to 35°C and immersion to 350 meters.
