Product Overview
Operating environment requirements for high lift potential are met by the nine-stage configuration of this 8-inch submersible pump. It is designed for intensive water distribution in agricultural and industrial sectors requiring high volume delivery from underground borehole sources. The assembly is compatible with vertical installations in deep wells or horizontal deployment provided a minimum 3-degree incline is maintained. This configuration serving municipal infrastructure projects needing precise pressure thresholds.
Technical performance parameters include a maximum head of 231.1 m and a flow capacity of 1216 L/Min through the 125 mm outlet. Equipped with a 37 kW motor for 415v three-phase power, the unit draws a rated current of 81.8 Amps during continuous duty. The semi-axial flow design achieves nominal delivery rates for high efficiency in water transfer tasks at 2900 rpm. performance metrics are verified for liquids with a density of 1.0 kg/dm³ during service.
Primary components such as the impellers, diffusers, and delivery head are made of cast AISI 316 Stainless Steel to handle aggressive borehole media. The motor is also constructed from 316 Stainless Steel and is rated for operation in liquids at temperatures up to 25°C. The system handles liquids containing suspended sand levels of 100 g/m³ through its nine stages and reduced impellers. A duplex stainless steel shaft and coupling are used to transmit power to the assembly.
The unit supports immersion depths reaching 350 meters and features a built-in non-return valve with a stainless steel spring to prevent backflow. Physical dimensions include a 198 mm maximum overall diameter, fitting within standard 8-inch borehole well casings. Internal tolerances are managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes supporting the shaft assembly. This design is intended for continuous industrial duty where reliable flow capacity is required.
FEATURES
- 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.
- 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.
- 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.
