Product Overview
Operating environment requirements for significant head potential are met by this six-stage 8-inch series submersible pump. It is designed for intensive water lifting where large volume delivery is required for municipal and industrial distributions from aquifers. The assembly supports vertical borehole installation and horizontal mounting in storage tanks with a 3-degree minimum inclination. This model provides the high lift and flow required for consistent water supply in residential or farming sectors.
Performance characteristics for this model include a maximum head of 161.7 m and a delivery capacity of 1333 L/Min through the 125 mm outlet. Equipped with a 30 kW motor for 415v three-phase power, the unit draws a rated current of 63.8 Amps during continuous duty. The semi-axial flow design achieves nominal flow rates of 55 m³/hr for efficient movement across the hydraulic assembly at 2900 rpm. All parameters are verified for clean water based on standard density.
Construction features cast AISI 316 Stainless Steel for wetted hydraulic parts including the delivery head, suction casing, and impellers. The motor is also constructed from 316 Stainless Steel and is rated for contact with liquids up to 25°C. The system handles liquids with suspended sand levels of 100 g/m³ through its six full-diameter stage configuration. A duplex stainless steel shaft and coupling transmit power to the impellers during industrial duty operation.
The electric pump is rated for immersion depths up to 350 meters and includes an integrated non-return valve to handle components during shutdown. Physical dimensions include a 198 mm maximum overall diameter, fitting within standard 8-inch well casings. Internal wear is managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes to ensure mechanical alignment and performance. The unit is intended for continuous industrial and municipal duty in borehole systems.
FEATURES
- Internal technopolymer POM-C wear rings maintain hydraulic clearances and reduce internal friction.
- Mechanical connection of the 8-inch motor follows NEMA standards for industrial system compatibility.
- The integrated non-return valve features a stainless steel spring to prevent fluid backflow.
- 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.
- 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.
