Product Overview
Deep well water supply tasks are the primary use for this 8-inch series submersible electric pump. It serves as a solution for extracting clean water from deep borehole sources where vertical or horizontal mounting is required. The design is suitable for installation in systems requiring high volume delivery for municipal or industrial service networks. This unit functions in environments where the motor remains in the lowest position with a minimum inclination of 3 degrees during horizontal deployment.
Technical performance metrics are defined by a 5.5 kW motor output operating on a 415v three-phase electrical supply. This model achieving a maximum head of 27 m and a maximum flow rate of 1333 L/Min through its 125 mm discharge outlet. The system draws a rated current of 12.7 Amps during continuous duty operation at a rotation speed of 2900 rpm. All performance values are calculated for liquids with a density of 1.0 kg/dm³ and standard kinematic viscosity.
Construction features cast AISI 316 Stainless Steel for the pump body, diffusers, and impellers to handle specific water chemistry in borehole conditions. This wet end construction is fabricated from cast stainless steel to withstand water containing sand content up to 100 g/m³. The assembly utilizes a semi-axial flow design and a 316 Stainless Steel motor rated for contact with liquids up to 25°C. The internal pump shaft and coupling are constructed from duplex stainless steel to manage the mechanical torque requirements.
Operational limits include a maximum electric pump immersion depth reaching 350 meters below the static water level. The unit maintains an overall diameter of 198 mm, including the two motor cable covers, making it compatible with 8-inch well casings. A rewindable motor design is utilized to support industrial duty cycles and maintenance requirements. Thermal protection is provided by the motor enclosure rating, and the assembly is intended for borehole wells with specified minimum diameters.
FEATURES
- 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.
- Mechanical connection of the 8-inch motor follows NEMA standards for industrial system compatibility.
- Stainless steel cable covers provide mechanical protection for motor power leads along the casing.
- A duplex stainless steel taperlock system secures the impellers to the shaft for torque transfer.

What motor power and electrical supply specification apply to this borehole pump?
The ZN855-01-3S has a 5.5 kW / 415v three-phase motor requiring a 415V electrical supply.
How high above the static water level can this pump elevate discharge water?
Pushing water high above the wellhead, the ZN855-01-3S maintains strong hydraulic output up to 27 m of head.
What maximum volumetric flow can be moved through the 125 mm discharge outlet?
The maximum fluid volume moved by the ZN855 01 3S reaches 1333 L/Min through its heavy-duty 125 mm discharge flange.
What alloy grades are used to fabricate the impellers and casing of this bore pump?
High-grade alloy selection for the ZN855_01_3S includes cast AISI 316 stainless steel wet end components and 316 motor construction for maximum corrosion protection.
How does the 198 mm overall diameter clear standard 8-inch well casing walls?
Borehole casing clearance for 8-inch pipes is ensured by the compact 198 mm maximum diameter of the ZN855-01-3S.
