Product Overview
Installation compatibility for vertical boreholes or horizontal deployment in storage tanks characterizes this 8-inch series submersible unit. It features a two-stage hydraulic end with one reduced impeller diameter to allow for fine-tuned pressure delivery in pumping projects. The assembly requires a minimum recommended incline when installed horizontally to ensure the motor remains in the lowest position. It serves as a high-capacity tool for lifting clean water from underground aquifers.
Technical performance metrics include a maximum head of 48.1 m and a maximum delivery rate of 1216 L/Min through the 125 mm outlet. The motor provides 11 kW of power from a 415v three-phase supply, drawing a rated current of 24.2 Amps. Performance characteristics are maintained through a semi-axial flow arrangement rotating at 2900 rpm. These specifications are based on the processing of clean water with standard density and kinematic viscosity.
Wet end components are constructed from cast AISI 316 Stainless Steel for the delivery casing, suction support, and internal diffusers. This material choice allows the unit to handle liquids with suspended sand levels reaching 100 g/m³ during standard operation. The motor is also made from 316 Stainless Steel and is rated for contact with liquids up to 25°C. The internal pump shaft and coupling are constructed from duplex stainless steel to manage mechanical loads.
This electric pump supports immersion depths of 350 meters and features a non-return valve built into the head to prevent backflow. Physical dimensions include a 198 mm maximum overall diameter, fitting within standard 8-inch well casings. Internal clearances are maintained by EPDM 70 bearing bushes and technopolymer wear rings to ensure mechanical alignment and hydraulic efficiency. The unit is designed for heavy-duty 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.
- 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.
- 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.
