Product Overview
Construction features based on high-grade cast alloys characterize this seven-stage 8-inch submersible unit for deep-well water supply. It provides robust lifting capabilities for irrigation systems and industrial distributions requiring high flow and head potential from underground sources. The unit is suitable for vertical installation in boreholes or horizontal deployment in pressure boosting stations with an inclination. This model serves as an efficient extraction tool for large-scale municipal water networks.
The model achieves performance metrics including a maximum head of 188.7 m and delivery capacity up to 1333 L/Min through its 125 mm outlet. Electrical specifications feature a 30 kW motor drawing a rated current of 63.8 Amps from a 415v three-phase supply. Efficiency is maintained at a rotation speed of 2900 rpm through precisely engineered hydraulic geometry designed for large-volume lifting. Performance data is verified based on clean water with standard kinematic viscosity.
Material integrity is ensured through cast AISI 316 Stainless Steel for wetted parts including the delivery head, suction support, and internal diffusers. The motor is also constructed from 316 Stainless Steel and is rated for contact with liquids up to 25°C during service. The assembly processes water containing suspended sand levels of 100 g/m³ through its seven-stage hydraulic arrangement. A duplex stainless steel shaft is used to transmit power to the hydraulic end during industrial service.
This electric pump supports immersion depths of 350 meters and features a non-return valve built into the head to prevent backflow during shutdown. Physical dimensions include a 198 mm maximum overall diameter, fitting within standard borehole casings including motor cable covers. Internal tolerances are managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes supporting the shaft alignment. This design is intended for continuous duty cycles in municipal water systems.
FEATURES
- Mechanical connection of the 8-inch motor follows NEMA standards for industrial system compatibility.
- 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.
- 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.
- Stainless steel cable covers provide mechanical protection for motor power leads along the casing.
