Product Overview
Application in large-scale agricultural irrigation and industrial distribution characterize this six-stage 8-inch series submersible electric pump. The reduced impeller configuration is intended for exact pressure delivery from deep borehole sources to surface facilities and municipal networks. The assembly supports vertical borehole installation and horizontal mounting in distribution systems with a 3-degree minimum incline. This configuration serves sectors requiring reliable head and large flow capacities.
Operating characteristics for this model include a maximum head of 150 m and a delivery capacity of 1216 L/Min through the 125 mm outlet. Electrical specifications feature a 30 kW motor drawing a rated current of 63.8 Amps from a 415v three-phase supply. Performance is maintained through a semi-axial hydraulic configuration achieving high efficiency with a nominal flow rate of 55 m³/hr. These metrics are verified for liquids with standard density at 2900 rpm.
Primary components such as the impellers, diffusers, and suction casing are constructed from cast AISI 316 Stainless Steel for material integrity. The motor is also constructed from 316 Stainless Steel and is rated for contact with liquids up to 25°C. The system handles liquids with suspended sand levels of 100 g/m³ through its six hydraulic stages. A duplex stainless steel shaft and coupling are used to transmit power to the assembly during continuous service.
The electric pump is rated for immersion depths up to 350 meters and features an integrated non-return valve to prevent fluid backflow. Physical dimensions include a 198 mm maximum diameter including motor cable covers, fitting within standard 8-inch borehole casings. Internal wear is managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes supporting the shaft assembly. This design is intended for heavy-duty municipal and industrial extraction tasks.
FEATURES
- Stainless steel cable covers provide mechanical protection for motor power leads along the casing.
- Mechanical connection of the 8-inch motor follows NEMA standards for industrial system compatibility.
- A duplex stainless steel taperlock system secures the impellers to the shaft for torque transfer.
- 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.
- 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.

What electrical input parameters ensure safe operation of this 26 kW / 415v bore motor?
Electrical safety protocols for the ZN855-06/2A-3S require a properly grounded 415V three-phase supply for its 26 kW / 415v motor.
What dynamic head pressure is available at the discharge port of this pump?
Fluid pressure output at the discharge port of the ZN855-06-2A-3S reflects its maximum dynamic head limit of 150 m.
Is the 125 mm outlet flange standard for industrial riser pipe connection?
Standard flange dimensions on the ZN855 06 2A 3S allow direct coupling of 125 mm riser pipe for 1216 L/Min flow delivery.
How do the stainless steel wetted parts prevent rust accumulation over time?
Rust accumulation on wetted surfaces is eliminated in the ZN855_06_2A_3S by using cast AISI 316 stainless steel wet end components and 316 motor construction.
What backflow check valve feature protects the motor shaft during pump shutdown?
Fluid backflow shock during sudden power interruption is prevented in the ZN855-06/2A-3S by an integrated check valve.
