Product Overview
Hydraulic design principles based on semi-axial flow characterize this 8-inch submersible unit intended for large-scale water extraction. The unit features a configuration compatible with both vertical borehole setups and horizontal pressure boosting stations. This specific model moves large volumes of water from deep underground reservoirs to surface distribution points. It serves as a dedicated extraction tool for irrigation systems and industrial water networks requiring consistent flow rates.
Operating characteristics for this single-stage configuration include a maximum total head of 27 m and a delivery capacity of 1333 L/Min. The power section utilizes a 5.5 kW motor drawing 12.7 Amps of rated current from a 415v three-phase supply. Performance is maintained at a rotation speed of 2900 rpm for liquids with standard density and viscosity. These metrics are verified through precise hydraulic geometry designed for deep borehole service.
Material construction utilizes cast AISI 316 Stainless Steel for wetted components including the suction support, diffusers, and impeller. This variant is equipped with a Duplex Stainless Steel motor, providing specific material properties for aggressive media contact. The assembly handles liquids with a maximum temperature of 25°C and processes water containing suspended sand levels of 100 g/m³. The internal shaft is made of high-grade duplex stainless steel to resist mechanical stress.
This electric pump is rated for immersion depths of 350 meters and features a 198 mm maximum overall diameter. A stainless steel non-return valve with an integrated spring is built into the delivery casing to protect the internal components. The system utilizes EPDM bearing bushes and technopolymer wear rings to maintain hydraulic efficiency during continuous duty cycles. The structure is designed for borehole wells where consistent water delivery and high material integrity are required.
FEATURES
- Stainless steel cable covers provide mechanical protection for motor power leads along the casing.
- The integrated non-return valve features a stainless steel spring to prevent fluid backflow.
- EPDM 70 bearing bushes support the pump shaft assembly and handle mechanical loads during rotation.
- 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.
- Internal technopolymer POM-C wear rings maintain hydraulic clearances and reduce internal friction.

What specific voltage and phase ratings apply to this 5.5 kW / 415v submersible motor?
Factory specifications for the ZN855-01-3R mandate a 415V three-phase electrical supply for its 5.5 kW / 415v motor.
What maximum pressure head is developed by the impellers of this 27 m unit?
Impellers in the ZN855-01-3R are trimmed to develop a maximum dynamic pressure head of 27 m in deep wells.
How many liters of water per minute pass through this 1333 L/Min rated bore pump?
Operating at 1333 L/Min, the ZN855 01 3R delivers high-volume water transfer through its standard 125 mm outlet connection.
How does this pump resist pitting and rust when deployed in brackish deep wells?
Brackish deep well deployment for the ZN855_01_3R is made safe through its corrosion-proof cast AISI 316 stainless steel hydraulics and a Duplex Stainless Steel motor.
What internal bearing materials resist abrasive wear when pumping gritty groundwater?
Grit resistance in the ZN855-01-3R is enhanced by EPDM 70 guide bearing bushes that support the duplex stainless steel shaft.
