Product Overview
Performance characteristics based on precise hydraulic matching define this four-stage 8-inch submersible pump intended for irrigation networks. The reduced impeller configuration is optimized for lifting groundwater from deep underground reservoirs to surface distribution points. The unit supports vertical well installation or horizontal deployment provided the motor remains in the lowest position during service. This model serves as an efficient extraction tool for municipal water supply projects requiring significant lift potential.
Hydraulic characteristics for this configuration include a maximum head of 96.3 m and delivery rates scaling up to 1216 L/Min. The electrical section consists of a 15 kW motor with a rated current of 32.1 Amps from a 415v three-phase supply. Efficiency is achieved through a semi-axial hydraulic arrangement rotating at 2900 rpm for efficient lifting in borehole environments. All technical performance values are verified for liquids with standard density and kinematic viscosity.
Material construction features cast AISI 316 Stainless Steel for the wetted components including the suction casing and diffusers. This variant is equipped with a Duplex Stainless Steel motor, providing enhanced material performance in aggressive borehole media. The system handles liquids with suspended sand concentrations up to 100 g/m³ and is rated for temperatures of 25°C. A duplex stainless steel pump shaft is fabricated to withstand the mechanical stresses of four hydraulic stages.
Ratings include a 350-meter maximum immersion depth and a 198 mm overall diameter including cable protection covers. A non-return valve with an integrated stainless steel spring is built into the assembly to prevent reverse rotation and backflow. Internal wear surfaces are managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes supporting the shaft alignment. This electric pump is designed for continuous duty cycles in municipal infrastructure and industrial projects.
FEATURES
- 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.
- 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.
- Stainless steel cable covers provide mechanical protection for motor power leads along the casing.

How does the 15 kW / 415v motor rating influence electrical breaker requirements?
Electrical circuit breakers protecting the ZN855-04/2A-3R should be rated for its 15 kW / 415v 415V three-phase motor.
What vertical head range makes this pump suitable for deep borehole extraction?
Deep shaft water recovery relies on the ZN855-04-2A-3R, which offers a total dynamic head capacity of 96.3 m.
What high-volume flow performance is delivered through the 125 mm outlet port?
High-flow water extraction with the ZN855 04 2A 3R produces up to 1216 L/Min through its standard 125 mm discharge port.
How does the stainless motor housing protect internal electrical windings from corrosion?
The motor housing of the ZN855_04_2A_3R features cast AISI 316 stainless steel hydraulics and a Duplex Stainless Steel motor to protect internal windings from groundwater ingress.
Is this 8-inch pump suitable for both vertical well shafts and horizontal pipelines?
Dual-mounting capability permits the ZN855-04/2A-3R to function in vertical deep wells or horizontal transfer pipelines.
