Product Overview
At the highest stage count in this group, the ZN616/30 provides thirty radial stages for applications demanding exceptionally high hydraulic lift. The six-inch wet end reaches a maximum head of 368 metres and retains a maximum flow of 367 L/Min.
The pump end uses AISI 316 stainless steel throughout its main construction, with AISI 316L stainless steel impellers and diffusers incorporating 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 limits operating water temperature to 35°C. Hydraulic performance is specified to EN ISO 9906 Grade 3B. Water is discharged through the Rp 2 1/2– (65 mm) threaded connection, with a standard 6-inch NEMA motor connection and maximum immersion of 350 metres with an L6W motor.
The microcast ASTM CF-8M (AISI 316 cast) discharge head and lower support incorporate the integrated stainless steel non-return valve. Safety-hook holes are provided to assist with controlled lowering and securing during deep borehole installation.

Will this borehole pump withstand mineral-laden water and suspended grit underground?
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 design of the ZN616/30 provides exceptional resistance to oxidation, safely passing suspended borehole sand up to 100 g/m³.
What electrical power input and supply voltage does this borehole pump demand?
Driving the heavy-duty assembly of the ZN616-30 requires a 6-inch NEMA L6W motor operating on 380–415 V, 50 Hz, three-phase at 47.3 A current draw, supporting well depths to 350 meters and temperatures to 35°C.
Does this submersible unit include an internal non-return valve for horizontal operation?
Internal piping safeguards in the ZN 616 30 feature an integrated stainless steel non-return valve in the delivery head, enabling horizontal mounting at a minimum recommended 3° incline with the motor positioned lowest.
What is the maximum vertical elevation pressure delivered by this deep well pump?
Pumping from subterranean water tables, the ZN_616_30 generates a peak dynamic head of approximately 368.2 m to maintain steady discharge flow.
What thread diameter attaches to the top outlet and what is the maximum delivery output?
Connecting the delivery riser to the Rp 2 1/2" (65 mm) top outlet allows the ZN616/30 to pump a peak flow volume of approximately 367 L/Min within standard 6-inch borehole installations.
