Product Overview
Hydraulic design principles utilizing high lift potential characterize this five-stage 8-inch submersible electric unit intended for industrial service. It serves as an efficient tool for moving clean water from deep boreholes to surface distribution networks or industrial storage facilities. The unit supports vertical well installation or horizontal deployment where the system layout allows for a 3-degree minimum incline. This model provides high head potential while maintaining large flow capacities from aquifers.
Technical parameters include a maximum total head of 134.8 m and peak flow rates of 1333 L/Min through the 125 mm discharge head. For power, the unit is equipped with a 22 kW motor drawing a rated current of 47.3 Amps from a 415v three-phase supply. Efficiency occurs through a semi-axial hydraulic arrangement designed for efficient lifting at a rotation speed of 2900 rpm. Performance data is verified for clean water based on standard density and viscosity characteristics.
Material construction features cast AISI 316 Stainless Steel for wetted parts including the delivery head, suction support, and diffusers. This variant 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. A duplex stainless steel shaft is utilized to transmit power to the five hydraulic stages.
The unit is rated for an immersion depth of 350 meters and maintains a maximum overall diameter of 198 mm including cable protection covers. A non-return valve with an integrated spring is situated in the delivery outlet to protect against reverse rotation and surges. Internal tolerances 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 industrial distribution projects.
FEATURES
- 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.
- 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.
- 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.
- Mechanical connection of the 8-inch motor follows NEMA standards for industrial system compatibility.
