Hydraulic design principles based on a five-stage configuration with three reduced impellers characterize this 8-inch series pump. It is engineered for agricultural systems needing high volume delivery and precise pressure matching for distribution lines from deep wells. The assembly is compatible with vertical borehole installations or horizontal mounting in tanks where a minimum incline is maintained. This model serves as a specialized tool for municipal water extraction and large-scale industrial projects.
Technical delivery capabilities for this model include a maximum total head of 117.5 m and a flow capacity up to 1216 L/Min via the 125 mm outlet. Powered by an 18.5 kW motor on a 415v three-phase supply, the unit draws a rated current of 38.5 Amps during operation. A semi-axial flow arrangement ensures consistent delivery with a nominal flow rate of 55 m³/hr at 2900 rpm. All technical specifications are verified for liquids with a density of 1.0 kg/dm³.
Primary components such as the impellers, diffusers, and delivery casing are constructed from cast AISI 316 Stainless Steel for material integrity. The motor is also made of 316 Stainless Steel and is rated for contact with liquids up to 25°C. The design handles water containing suspended sand levels of 100 g/m³ through its five-stage hydraulic arrangement. A duplex stainless steel shaft and coupling are utilized to transmit power to the hydraulic end to handle generated torque.
The unit handles immersion depths of 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 diameter, fitting within standard 8-inch borehole casings. Internal wear surfaces are managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes to ensure mechanical alignment and hydraulic performance. The unit is designed for heavy-duty industrial extraction and municipal supply applications.
Features
- 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.
- 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 stainless steel suction strainer excludes large particles from entering the hydraulic stages.
- 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.
