Product Overview
Performance characteristics optimized for robust distribution characterize this eight-stage 8-inch series submersible electric pump. It provides high pressure and flow for agricultural and municipal distribution projects requiring head potential from borehole sites. The unit supports vertical well installation or horizontal deployment where the layout allows the motor to be in the lowest position. This model serves as an efficient extraction tool for industrial water supply projects needing specific lift parameters.
Technical parameters include a maximum head of 204.1 m and delivery capacity up to 1216 L/Min through its 125 mm discharge outlet. Electrical power is supplied by a 37 kW motor drawing 81.8 Amps of rated current from a 415v three-phase supply. Delivery efficiency occurs through a semi-axial hydraulic arrangement designed for deep borehole service at a rotation speed of 2900 rpm. All performance data is verified based on liquids with standard clean water density.
Material integrity is ensured through cast AISI 316 Stainless Steel for components including the delivery casing, suction casing, and diffusers. This variant features a Duplex Stainless Steel motor, providing resistance in aggressive borehole media found in deep wells. The assembly processes water containing suspended sand concentrations up to 100 g/m³ and is rated for temperatures up to 25°C. The internal duplex stainless steel shaft manages the generated mechanical torque during rotation.
Rated for immersion depths of 350 meters, the unit features a maximum overall diameter of 198 mm including motor cable protection covers. A non-return valve with an integrated stainless steel spring is built into the assembly to prevent reverse rotation and surges. Internal clearances are maintained 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.
FEATURES
- 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.
- Mechanical connection of the 8-inch motor follows NEMA standards for industrial system compatibility.
- 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 durable are the internal components during submerged operation?
The ZN855-08/2A-3R is built using cast AISI 316 stainless steel pump casing with a duplex stainless steel motor, ensuring long-term structural integrity in demanding borehole environments.
Does this pump require a three-phase power connection?
The ZN855-08-2A-3R is driven by a 37 kW / 415v motor requiring 415V three-phase electrical power for high-demand pumping.
How does the pump prevent reverse liquid flow during shutdown?
Yes. The ZN855 08 2A 3R includes an integrated non-return check valve with a stainless steel spring in the discharge port to limit backflow during shutdown.
How high can this borehole pump push water up to the surface?
Capable of reaching a maximum total head of 204.1 m, the ZN855_08_2A_3R delivers strong vertical pressure for deep well water extraction.
What size pipe connects to the top discharge outlet?
Outputting up to 1216 L/Min through its 125 mm outlet port, the ZN855-08/2A-3R provides rapid fluid distribution for water networks.
