Product Overview
Construction features based on a three-stage hydraulic end characterize this 8-inch submersible pump intended for high-volume clean water transfer. It is designed for distribution from deep boreholes to surface storage reservoirs or agricultural irrigation networks. The unit supports both vertical installation in deep wells and horizontal deployment in pressure tanks with a 3-degree incline. This model serves as a dedicated solution for municipal networks needing consistent lift and flow capacity.
Hydraulic performance is defined by a maximum head of 80.9 m and a flow rate of 1333 L/Min through the 125 mm discharge outlet. Equipped with a 15 kW motor for 415v three-phase power, the unit draws a rated current of 32.1 Amps during operation. The semi-axial flow design achieves high delivery efficiency for large-scale extraction tasks at a rotation speed of 2900 rpm. All metrics are validated for liquids with a density of 1.0 kg/dm³ during industrial service.
Primary components such as the impellers, diffusers, and suction 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 system handles water with suspended sand concentrations of 100 g/m³ through its three-stage hydraulic arrangement. A duplex stainless steel shaft and coupling transmit power to the hydraulic stages during continuous duty.
This electric pump is rated for immersion depths up to 350 meters and features a built-in non-return valve with a stainless steel spring. Physical dimensions include a 198 mm maximum overall diameter, fitting within standard 8-inch borehole casings. Internal clearances are maintained by technopolymer POM-C wear rings and EPDM 70 bearing bushes to ensure mechanical alignment and efficiency. The unit is designed for heavy-duty industrial extraction and municipal water supply applications.
FEATURES
- Internal technopolymer POM-C wear rings maintain hydraulic clearances and reduce internal friction.
- 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.
- 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.
