Product Overview
Performance characteristics optimized for consistent extraction define this 8-inch submersible electric pump designed for rural infrastructure. The two-stage configuration with one reduced impeller is intended to handle demanding borehole lifting tasks while maintaining specific hydraulic parameters. The system is suitable for vertical well installation or horizontal deployment where layout requires a low-profile incline. This unit serves as a robust solution for irrigation and livestock needs from underground sources.
The system achieving a maximum head of 48.1 m and delivery rates scaling up to 1216 L/Min through its its 125 mm discharge outlet. Power is delivered by an 11 kW motor operating on 415v with a rated current draw of 24.2 Amps during service. The semi-axial flow design is used to move high volumes of water efficiently at a rotation speed of 2900 rpm. All performance values are calculated for liquids with a density of 1.0 kg/dm³.
Material construction features cast AISI 316 Stainless Steel for wetted parts including the impellers, diffusers, and delivery head. This model is equipped with a Duplex Stainless Steel motor, providing durability in aggressive water conditions found in deep wells. The assembly processes water containing suspended sand concentrations up to 100 g/m³ and is rated for temperatures of 25°C. The internal pump shaft is made of duplex stainless steel to resist mechanical stress.
The system is rated for a maximum immersion depth of 350 meters and features a 198 mm overall diameter including cable covers. A built-in non-return valve with a stainless steel spring protects the internal components from backflow and pressure surges. Internal wear is managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes which support the shaft assembly. The pump is intended for continuous industrial duty in large-scale water distribution projects.
FEATURES
- A stainless steel suction strainer excludes large particles from entering the hydraulic stages.
- 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.
- 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.

What continuous power output is delivered by the motor of this 7.5 kW / 415v pump?
Delivering steady mechanical shaft power, the ZN855-02/1A-3R motor requires 7.5 kW / 415v from a 415V three-phase supply.
How does the hydraulic stack generate a maximum total dynamic head of 48.1 m?
Total dynamic head development in the ZN855-02-1A-3R reaches 48.1 m, providing superior vertical pumping power.
Is this 1216 L/Min max flow rate verified for continuous high-capacity transfer?
High-volume transfer certification confirms the ZN855 02 1A 3R delivers up to 1216 L/Min through its 125 mm outlet.
Are all wetted pump components fabricated from high-grade stainless steel alloys?
Comprehensive corrosion resistance across the ZN855_02_1A_3R is achieved by utilizing cast AISI 316 stainless steel hydraulics and a Duplex Stainless Steel motor.
How do POM-C wear rings and EPDM bearings extend pump life in sandy boreholes?
Wear-resistant POM-C rings in the ZN855-02/1A-3R minimize internal recirculation and prevent sand abrasion during operation.
