Product Overview
Where pressure boosting requires higher borehole lift, the ZN616/10 provides ten radial stages within a six-inch pump-end configuration. Its maximum head is 123 metres, while the hydraulic capacity remains 367 L/Min.
The pump end uses AISI 316 stainless steel, with AISI 316L impellers and diffusers fitted with removable wear rings. The shaft is Duplex stainless steel UNS S 31803 and the replaceable coupling is Duplex stainless steel UNS S 32304. The wet end is specified for suspended sand up to 100 g/m³.
With an L6W motor, operating water temperature is limited to 35°C. Performance is specified to EN ISO 9906 Grade 3B, with water delivered through the Rp 2 1/2– (65 mm) threaded outlet. The standard 6-inch NEMA motor connection accommodates the L6W motor, with maximum immersion of 350 metres.
A microcast ASTM CF-8M (AISI 316 cast) discharge head and lower support form the discharge assembly. The integrated stainless steel non-return valve provides backflow control, while safety-hook holes assist with borehole installation.

What thread size is featured on the discharge outlet and what maximum flow rate is possible?
Plumbing discharge connects directly through the top Rp 2 1/2" (65 mm) port, where the ZN616/10 discharges up to a peak flow of approximately 367 L/Min inside standard 6-inch borehole installations.
What construction materials protect this borehole pump against underground chemical attack?
Constructed from high-grade 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, the ZN616-10 resists mineral oxidation and erosion while managing suspended sand up to 100 g/m³.
What are the motor power rating and electrical voltage specifications for this unit?
Electrical operation involves pairing the ZN 616 10 with a 6-inch NEMA L6W motor rated at 7.5 kW on 380–415 V, 50 Hz, three-phase pulling 17 A, rated for water temperatures up to 35°C and submersion to 350 meters.
Is an internal non-return valve built into this pump and is horizontal orientation supported?
Preventing line drainage during shutdown, the ZN_616_10 incorporates an integrated stainless steel non-return valve in the microcast ASTM CF-8M discharge head and permits horizontal installation at a minimum recommended 3° incline with the motor lowest.
How high can this submersible bore pump elevate water from deep underground water tables?
Under full operating conditions, the ZN616/10 achieves a maximum vertical dynamic head of approximately 123.3 m, ensuring strong discharge pressure from deep borehole shafts.
