Product Overview
Installation flexibility for deep borehole wells or horizontal distribution tanks distinguishes this four-stage 8-inch submersible unit. It features two reduced impellers for head fine-tuning to provide a solution for high-volume distribution in farming infrastructure. The pump is compatible with vertical installation or horizontal deployment in tanks where a 3-degree incline is maintained. This configuration serves agricultural and industrial sectors needing precise pressure parameters and consistent lifting.
Performance metrics are defined by a maximum head of 96.3 m and a maximum delivery rate of 1216 L/Min through the 125 mm outlet. Powered by a 15 kW motor on a 415v three-phase supply, the unit draws 32.1 Amps of rated current during operation. The semi-axial flow design achieves high efficiency in water transfer tasks at a rotation speed of 2900 rpm. These parameters are validated for liquids with a density of 1.0 kg/dm³ and standard clean water viscosity.
Wet end components are fabricated from cast AISI 316 Stainless Steel for wetted parts including the diffusers, impellers, and delivery casing. The motor is also made of 316 Stainless Steel and is rated for contact with liquids up to 25°C during continuous service. The system processes water with suspended sand levels of 100 g/m³ without loss of material integrity. A duplex stainless steel shaft and coupling are used to transmit power to the four hydraulic stages.
The unit handles immersion depths of 350 meters and features a 198 mm maximum overall diameter including cable protection covers. A built-in non-return valve with a stainless steel spring is situated in the delivery head to prevent backflow and reverse rotation. Internal clearance is managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes supporting the shaft assembly. This electric pump is intended for continuous industrial and municipal duty in deep borehole systems.
FEATURES
- A duplex stainless steel taperlock system secures the impellers to the shaft for torque transfer.
- The integrated non-return valve features a stainless steel spring to prevent fluid backflow.
- Mechanical connection of the 8-inch motor follows NEMA standards for industrial system compatibility.
- Internal technopolymer POM-C wear rings maintain hydraulic clearances and reduce internal friction.
- 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.
- Stainless steel cable covers provide mechanical protection for motor power leads along the casing.

What electrical supply setup is needed for this 15 kW / 415v 8-inch submersible unit?
Configuring power for the ZN855-04/2A-3S requires a three-phase 415V supply capable of driving its 15 kW / 415v motor.
Can this submersible unit push water up long overland inclines reaching 96.3 m?
Overland pipeline inclines are smoothly handled by the ZN855-04-2A-3S, featuring a maximum head rating of 96.3 m.
How many liters per minute can this pump transfer to surface storage systems?
Surface storage systems are rapidly filled by the ZN855 04 2A 3S, delivering up to 1216 L/Min through a 125 mm connection.
What alloy specifications make this pump resilient against aggressive well fluids?
Resilience against aggressive well chemistry is a hallmark of the ZN855_04_2A_3S, built with cast AISI 316 stainless steel wet end components and 316 motor construction.
Does the integrated check valve eliminate the need for external backflow valves?
External backflow check valves are unnecessary for the ZN855-04/2A-3S due to its built-in spring-loaded non-return valve.
