Product Overview
Material construction using cast alloys defines the durability of this eight-stage 8-inch series pump intended for intensive lifting. It provides a solution for moving large volumes of groundwater from deep boreholes to surface networks or storage facilities in irrigation projects. The unit supports vertical well installation or horizontal deployment in distribution networks provided the motor remains at the lowest position. This model serves as an efficient extraction tool for sectors requiring reliable head potential.
Operating parameters include a maximum head of 215.6 m and delivery rates scaling up to 1333 L/Min through the 125 mm discharge outlet. Electrical power is delivered by a 37 kW motor drawing 81.8 Amps of rated current from a 415v three-phase supply. High delivery efficiency occurs through a semi-axial flow arrangement designed for deep borehole service at a rotation speed of 2900 rpm. All performance values are verified for liquids with standard density and viscosity.
The wet end is constructed from cast AISI 316 Stainless Steel for components including the delivery casing, suction casing, and impellers. This variant features a Duplex Stainless Steel motor, providing durability in aggressive borehole environments found in industrial and municipal wells. The assembly processes water containing suspended sand concentrations up to 100 g/m³ and is rated for temperatures of 25°C. A high-grade duplex stainless steel pump shaft manages theGenerated mechanical torque.
Operational ratings include a 350-meter maximum immersion depth and a 198 mm maximum overall diameter including motor cable covers. A built-in non-return valve with a stainless steel spring is situated in the delivery outlet to protect against backflow and mechanical surges. Internal wear surfaces are managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes supporting the shaft alignment. This electric pump is designed for continuous duty cycles in deep wells.
FEATURES
- Stainless steel cable covers provide mechanical protection for motor power leads along the casing.
- 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.
