Product Overview
Operating characteristics optimized for high-pressure lifts define this seven-stage 8-inch series submersible electric unit for industrial extraction. It serves as an efficient extraction tool for agricultural distribution projects and municipal water networks needing consistent groundwater delivery from borehole sites. The unit supports vertical well installation or horizontal deployment where the system design allows the motor to remain at the lowest position. This model providing specific lift capacity via reduced impeller matching.
Operating parameters include a maximum total head of 177.1 m and delivery rates scaling up to 1216 L/Min through the 125 mm outlet. Power is supplied by a 30 kW motor drawing a current of 63.8 Amps from a 415v three-phase electrical supply. High delivery efficiency occurs through a semi-axial flow arrangement designed for deep borehole service at a rotation speed of 2900 rpm. performance metrics are verified for clean water based on standard density.
Construction utilizes high-grade cast AISI 316 Stainless Steel for wetted hydraulic parts to provide resistance in aggressive media environments. This variant features a Duplex Stainless Steel motor, providing enhanced durability in borehole wells with aggressive water chemistry. The assembly handles water containing suspended sand concentrations up to 100 g/m³ and is rated for temperatures up to 25°C. A high-grade duplex stainless steel pump shaft manages mechanical stresses during service.
Operational ratings include a 350-meter maximum immersion depth and a 198 mm maximum overall diameter including motor cable protection covers. A built-in non-return valve with a stainless steel spring is situated in the delivery head to prevent backflow and mechanical surges. Internal wear surfaces are managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes supporting the shaft alignment. The pump is designed for continuous duty cycles in municipal infrastructure.
FEATURES
- 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.
- Internal technopolymer POM-C wear rings maintain hydraulic clearances and reduce internal friction.
- Stainless steel cable covers provide mechanical protection for motor power leads along the casing.
