Product Overview
Material construction using cast alloys defines the durability of this dual-stage 8-inch submersible electric pump intended for intensive distribution. It provides the high flow and head required for agricultural distribution from deep wells or borehole networks. The unit is designed for vertical borehole installation or horizontal deployment in pressure boosting stations with a specific minimum inclination. This model serves as a high-capacity extraction tool for large-scale municipal water supply projects.
Performance metrics are defined by a maximum head of 53.9 m and a delivery capacity of 1333 L/Min through the 125 mm discharge outlet. The unit is powered by an 11 kW motor drawing 24.2 Amps of rated current from a 415v three-phase supply. Operation is achieved through a semi-axial hydraulic geometry rotating at 2900 rpm for efficient lifting from underground reservoirs. All technical specifications are validated for liquids with standard density and kinematic viscosity.
The wet end is constructed from cast AISI 316 Stainless Steel for all wetted parts including the suction casing and diffusers. This variant features a Duplex Stainless Steel motor, providing enhanced material performance in specific borehole environments. The assembly handles liquids with suspended sand concentrations of 100 g/m³ and is rated for temperatures up to 25°C. A duplex stainless steel pump shaft is made to withstand mechanical stresses during high-volume water movement.
Operational ratings include an immersion depth limit of 350 meters below the surface in municipal or industrial wells. The pump has a maximum overall diameter of 198 mm, which accounts for the inclusion of two motor cable covers. A stainless steel non-return valve with an integrated spring is built into the assembly to prevent reverse rotation and mechanical shocks. Internal tolerances are maintained by technopolymer POM-C wear rings and EPDM 70 bearing bushes.
FEATURES
- Stainless steel cable covers provide mechanical protection for motor power leads along the casing.
- Internal technopolymer POM-C wear rings maintain hydraulic clearances and reduce internal friction.
- The integrated non-return valve features a stainless steel spring to prevent fluid backflow.
- A stainless steel suction strainer excludes large particles from entering the hydraulic stages.
- EPDM 70 bearing bushes support the pump shaft assembly and handle mechanical loads during rotation.
- A duplex stainless steel taperlock system secures the impellers to the shaft for torque transfer.
- Mechanical connection of the 8-inch motor follows NEMA standards for industrial system compatibility.

What amperage draw and voltage rating characterize this 9.3 kW / 415v borehole unit?
The electrical profile of the ZN855-02-3R is defined by a 9.3 kW / 415v motor operating on 415V three-phase current.
Is this 53.9 m maximum dynamic head rating sufficient for high-altitude delivery?
High-altitude water delivery is made possible by the ZN855-02-3R, engineered for a maximum dynamic head of 53.9 m.
How much water volume can this pump extract per minute from deep boreholes?
Deep borehole water extraction with the ZN855 02 3R yields a maximum delivery rate of 1333 L/Min via a 125 mm port.
How does the alloy construction prevent rust formation during long immersion periods?
Long immersion cycles for the ZN855_02_3R produce no rust accumulation thanks to its cast AISI 316 stainless steel hydraulics and a Duplex Stainless Steel motor.
Can this submersible unit be used in horizontal water storage tank setups?
Reservoir pressure boosting with the ZN855-02-3R supports horizontal mounting down to a minimum 3-degree tilt angle.
